As I write this it does not seem possible that my first Ag App Blog was written over five years ago. https://osunpk.com/2013/07/30/agriculture-app-for-the-ipad-and-iphone/. When I wrote that first blog I had 76 apps on my iPad a year later I had over 200 apps on the same iPad posted the third app focused blog https://osunpk.com/2014/12/09/agriculture-apps-200-strong-and-growing/.
Today I still enjoy looking for apps and I am also having a lot of fun developing apps. With a team of computer science students we have released twenty eight apps in both iOS and Andriod platforms http://www.dasnr.okstate.edu/apps. After I had picked up a few new apps, broke the 300+ mark, I found that my five year old iPad 2 was not quite as quick as it used to be and I had to upgrade prior to doing my Scouting App Review https://osunpk.com/2017/08/03/scouting-app-review/.
Even after 300+ apps I still have a few of the same original suggestions, like the general rule of thumb “If I cannot figure it out in 3 minutes it’s GONE. An app should be intuitive, easy to use and have a purpose. They only exception to the 3 minute rule is the Scouting and Mapping Apps. Because of their complexity I allow them 5 minutes, and then I am done. Any app with GIS in its name gets much more time”. As far as searching for apps terms such as Corn, Soybean, and Wheat return more games and dietary apps than useful ag apps. Multiple key work searchers is important. If you find a good app go into iTunes or Google Play and check out the other apps created by the developer. Chances are if the developer has made one app you like there will be other well suited to your needs.
But to be honest as you can expect of those 300+ apps 95% only get opened when I have to give a talk. Recently I have had request to update my list of apps but instead of spending the countless hours organizing my thoughts on the 300+, I decided on just sharing with you those apps which have made their way onto my cell phone because I do use them. Many of these are on my original blog 5 years ago.
Tank Mix is a handy app that allows the user to create chemical inventories, plan spray jobs, share the details and save for later. Minus wading through the list of chemical this is a very intuitive app and provides a great deal of information. The ability to create a library of chemical and application really streamlines the systems.
SPRAY SELECT Apple
Spray Select was the first app I downloaded. While over the years it has had its fair share of bugs, in my line of work this app is a gem. In a day I may go from spray a contact, to a fertilizer, to a systemic. Not to mention the wide range of GPAs I run at. Being able to to select my speed and GPA then have a list of tips and droplet sizes makes this app critical for my project. I primarily use TeeJet but if you use Hypro check out AgPhDs SprayTipGuide, if you use Greenleaf download NozzleCalc, JohnDeere has an app for their nozzles also.
I have two Nutrient Removal Calculators on my iPhone the Fert Removal from AgPhD and Nutrient Removal from IPNI. I give Fert Removal the leg up because it provides nutrient values for more than just the macro nutrients.
The AgPhDs put out another nice app in Deficiencies. Nice funcitonality but image library is a bit limited. It is my hopes that they are adding to this over time. Much like with the nutrient removal tools I give second runner up in this group to the IPNI PlantImages app. It has a larger image data base but at the time of this blog it needs updating and is not functioning on all platforms. Both apps are on my phone and are great tools for someone new in the field, or someone who has been around a while but who’s client needs to a see a second opinion.
I like the easy of use for of the Corn Yield Calculator. It is a quick, easy, and clean way to estimate yield. However when I pulled the links for this app it seems as though since I first downloaded the app, a fee has been added, $2.99. For some of you it may be worth the charge. However University of Wisconsin has a nice app named Crop Calculators. It has several functions but the UI (user interface) is not as clean.
Another app by the Ag PhDs is on my list. For me the Harvest Loss App is what I use as an example for the perfect “app”. Harvest loss allows the user to choose the commodity and current price. Then the number of grains found in a square foot after harvest is counted. This provides an economic value to properly setting a combine. What more powerful tool than money lost is there to impact change.
These are not the only Weed Identification apps, but they are my favorite. University of Missouri’s IDWeeds was the first of its kind and has made some fantastic improvements over the years. Monsanto’s WeedID app is, IMHO, one of the cleanest and nicest user interfaces available. Both function similarly, the user selects grass or broadleaf, then chooses the appropriate physiological features of the weed in question. A list of weeds fitting the description is compiled. Pictures and more in-depth descriptions are available.
While this app is built for the UK, being in the southern Great Plains wheat is king and this is a very useful app when it comes to cereal disease. While it does not have a good ID tool it has a great list of diseases, images and very in-depth descriptions.
This app just makes me smile. But it really does have some great features and could be quite useful or any cattle producer. By considering the consistency of the pile the quality of the forage/feed can be estimated.
Of course I have all of the OSUNPK apps on my phone but here are a few that I think were homeruns. The full list can be found at http://www.dasnr.okstate.edu/apps
While Canopeo is not mine its the best thing since sliced bread. This app uses the camera on your phone or tablet to get a % canopy cover. The Android version even has a video version. The applications for this app are endless.
OKSTATE SOIL SAMPLE
Designed for individuals who send samples to the OSU Soil, Water, and Forage Testing Labs (SWFAL). User can collect the GPS location of a sample, add notes, and tie it to your lab ID and sample number via a barcode. I know some who just use this app to get Lat Longs from sample points. At this point the app is not tied to the Lab system. But a file can be emailed with all of the saved data.
Simple calculator that will calculate annual nutrient additions when you have a irrigation water test.
Handy app built to help calibrate grain drills to sow canola with the added function of determining rates of other grains and fertilizers.
Non Ag but extremely popular app designed for a DIY food plot. Pick your species of interest and planting window and a list of applicable plants and their agronomic recommendations are provided. Lists can be saved and shared.
Built to help graduate students prep fertilizer for plot application. The app also has a unit conversation calculator.
If you are free in the middle of July, make your way to InfoAg in St Louis (July 17-19, 2018). I will be going through these app and many more in a app review and demonstration. For more info on InfoAg check out their website. https://infoag.org/

For 2017 InfoAG I was challenged to review the available mobile scouting apps. While I have been reviewing ag apps since the summer of 2013 https://osunpk.com/2013/07/30/agriculture-app-for-the-ipad-and-iphone/ , I had yet try to tackle a group as complex as scouting apps.My first challenge was to locate all relevant apps. My search began using social media and the search terms Crop Scouting, Field Scouting, Ag Scouting, and Farm Scouting for both iPhone and iPad apps. After a week-long hunt I had found around 30 apps, although I am sure I missed a few. As most of these app require payment, I assumed most would have a 30 day free-trial period. So towards the end of June, about a week out from the meetings, I started trying to gain access. As I did this I kept records in an excel file on how the process was going. I found that with nine apps I had immediate access via the app, for seven apps I was able to request a demonstration, and for another six I used the contact us option and requested a demo via that method. By Friday, July 21st, I had access to 17, my presentation was on Wednesday the 26th. I should note that a few more demos were provided after the presentation, but are not included in this review.
After I gained access I went into iTunes and Google play to determine where they could be found.
During the signup and trial phase most apps offered/suggested/preferred that I went through training for supervised demonstration of their applications. I chose to pass on the training. The first reason was simply due to time constraints, as my presentation data was approaching rapidly by this point. More importantly, I wanted this review to be useful to the people I know that are interested in these apps, and I also know that many of these people are just the type to try something without instructions, you know who you are! So my observations are based entirely on how well I was able to intuitively use the applications. There is no question if I had gone through the training I would have picked up on several items I likely missed. Also it should be noted many of the demo versions I had access to had limited functions.
Evaluation of the apps took place in the field, office, and home. Near the end of the project I spent many hours reviewing notes and going back and forth between the mobile and web based versions.
As I was working through each of the apps, I tried to put myself in the shoes of a private crop scout, much like many of my friends are. This is an important point to consider because as I dug deeper into the applications I came to realize that many of these apps were developed with larger consulting firms in mind. The next table has some important ramifications depending upon the user. Almost every application had a downloadable software or web-based form utilized for operation management. Some of the apps that fell into the category of “Needed to Perform” are the apps which a field boundary or scouting trip could not be initiated from the mobile device.
It is those applications that needed a manager to set fields and/or assign task which I deemed where meant for larger consulting groups, as this strategy would not be efficient for a one or two person operation. These applications did have some impressive functions allowing managers to follow scouts progress and direct operations near real time.
One of the first tasks I wanted to review was the creation of field boundaries. From the view point of a private consultant, I put an emphasis on those apps which could draw field boundaries from the mobile device. The use of CLUs (common land units) was an interesting way to load boundaries, more on that in a bit. Most applications that utilized CLUs did so in the desktop program, however several apps also had the option within the mobile device. A few of the desktop apps also allowed the import of shape files to set field boundaries, it was the only option in Field X.
Drawing field boundaries was the one area that some apps really separated themselves in terms of functionality. For me, the mobile device field boundary winner was the AgDNA app. Their use of the cross-hair with pin drop at the top of the screen increased the accuracy of the pin set. Often, when dropping pins or moving the pins in other apps, the placement would be off due to poor finger to eye coordination. Sirrus and Agrian tied for 2nd, and both provided a zoom option for the pin after placement. AgriSiteIPM provided a nice function where the application dropped an additional pin between any two that I placed. I found this to help speed up the task and allowed me to make some refinements a bit quicker. All other applications were equal.
Now back to the CLU conversation. With CLUs the application draws the boundaries for you. I must say that, when it works properly, it is a very nice function. Below are two examples of fields I used CLUs to define field boundaries.
However CLUs did not consistently identify the proper fields. In the examples below, the L field on the right is actually two separate fields with a dirt road between them, the example on the right only identified the grass waterway and left the field unselected. The saving grace is that all of the apps with CLU option also had the draw option, so if the CLU did not work I could just draw it in manually. So in the long run, no harm no foul.
The next task I evaluated was entering crop/field information, such as crop type, variety/hybrid, planting date, fertilizer, and pesticide applications. My preference was that this task could be accomplished from the mobile device. As it turned out many of the applications which would function better for a larger organization did not allow for this information to be entered via the mobile device. Also, as a soil scientist, I was bummed by the lack of apps with the ability to bring in SURGO data, and even more let down that the majority of the desktop versions did not utilize this data layer. So, with that being said, a big props to FarmLogs for being the only mobile app with the capability of downloading SURGO data layers. Climate had an interesting “soils” portion of the app, where it provided a table listing predominate soil texture, percent organic matter, soil pH and CEC. A note on the Climate soils data, while the soil texture, OM, and CEC are not far off the average, I felt that the pH was off by a bit. This is not unexpected however as, of all the reported variables, pH is the most impacted by human activities.
Below is a summation of the weather functions of mobile and desktop applications. I categorized the data as Historical (multi-year average), Past (either calendar or growing period weather), Current (today’s temp and wind), and Forecast (3-10 day forecast on either a daily or hourly basis). From the consultants viewpoint if I am out in a field trying to determine if I should recommend a nutrient or pesticide application weather is a BIG part of that decision process. So having the current weather and forecast in hand when I have to make that call is a great tool. The past/historical data is something I really enjoyed looking at, and could spend hours doing, its impact on management decision is not as critical as forecast, but is still a tool I appreciated. With that, Climate and Sirrus were the only mobile apps with a forecast function while Farm Logs had nice past data functionality.
Within the Scouting Section I was looking for in field functionality of collecting information and sharing. As expected, all apps provided the ability to drop pins via GPS and add notes and images. Some apps also allowed the user to select the location to drop pins. I liked the ability to add stand counts and a few applications actually allowed the users to collect multiple sampling points and provide an average. This is a nice function that promotes proper sampling techniques. Both Agrian and Sirrus provide directed sampling functions, I specifically liked being able to set up a grid on site and sample immediately. From the aspect of a private consultant, I felt it would be extremely important to be able to share scouting reports and recommendations from the application in-field. Some of these were very simplistic emails others send PDFs.
As far as just “cleanness” and functionality of scouting goes, I personally really liked the scouting layout provided by OpenScout. I also gave good marks to AgraScout and Agrian for their user friendly interfaces.
Personally I am a big fan of having pictures of the pest. Aker Scouts function of having images with their pick list was nice and I could see it really coming in handy. Better yet, when the pest was selected a detailed description was presented. AgraScout also had a nice function that when a pest was selected from the picklist an image of the pest would pop up. Unfortunately, at the time of testing this app had a bug and in the insect picklist the wrong insect often came up.
First look at the ScoutPro I loved its function of a step wise pest selection tool to get too my problem. That said, after a few times it wore me out. I did not need this process to identify pigweed and johnsongrass, and felt it was forcing me to make more clicks than necessary.
The final function hearkens back to my precision ag background. Four of the applications provided the opportunity to build management zones, and from what I could determine from my versions, three of the applications could build and export shapefiles for application. With the image arms race so active right now, I also looked at which applications included satellite imagery. The five listed below are the ones that actively promote the purchase of imagery within the mobile or desktop applications.
The following are comments taken directly from my observations. I have left all notes in this, and in some cases you can see where I could not find a function, then later made a note that it was found.

My final take home from this task was that I don’t want to have to do this again. It was a wonderful challenge that took a lot of time and energy, and I still only looked at 50% of the available applications. My comments to those looking for an app, reach out and try as many as possible. Every app has its own fit and there is no one size fits all. If you find one or two you like TAKE THE TRAINING, I know I missed aspects of many of these applications, but I was testing the intuitive nature of the programs. My comments to application developers, don’t forget the private consultant. I really don’t feel like many of the applications I tested had the independent consultant in mind. Instead they are targeting large groups, and this is understandable from a marketing stand point. Consider adding a function that, when a scout leaves the field, a note is sent to the producer notifying them that the field has been checked. I can see this being a great value added product, allowing the producer to immediately know that their scout is taking care of them.
It was just 11 months ago when I wrote my last blog on Ag apps. Since that time I have presented on the topic several times, added nearly 100 new apps, have filmed several designated segment on sunup featuring apps (these can be seen at http://www.youtube.com/osunpk), and released two (soon to be three) apps myself. Below is the introductory slide I have been using in all of my app talks, on this slide you can see how the number of apps have been increasing overtime. In this update I wanted to share some of the new sections I have added to manage the vast number apps and go through some of my favorite apps in each of the sections.
Finding the right app has not changed as I still just give an app 3 minutes before a keep or drop decision is made, however since a year ago some of the key words are now less useful. For example a search for wheat will bring up droves of gluten free diet apps. None of these fit the bill for what I am looking for. Though out the blog you can click on pictures screenshots to get a better view of the app buttons.
Ag News and Weather
Still a very large section with little change for my recommendations, just go with what suits you in layout and reporting. I personally use RonOnRON (Ron Hays, the voice of Oklahoma Agriculture), DTN/PF, AG/Web, and AgWired.
This includes peer review publications, resource guides and extension materials.
The majority of the Calculator apps preform relatively simple functions without the need of cellular or wifi connectivity. The Ag PhDs have two apps in the section I want to highlight, HarvestLoss and Fert. Removal. Both apps are useful tools in making management decisions. HarvestLoss allows the user to calculate the economic loss of a poorly set combine while Fert. Removal allows the user to select from a wide range of crops and see an exit ate of nutrient removal based upon selected yield level. Other useful apps are Growing Degree which allows the user to see cumulative heat units a crop has received anywhere in the US, Corn Yield Calc estimates corn yield based on ear girth and length, Canola Calc is a great apps produced by Pioneer which calculates the proper planting rate of canola based upon several factors and the Kansas Wheat Yield Calculator KWYC, uses growth stage stalk counts, height and/or NDVI to estimate potential grain yield.
This section is filled with University Extension handbooks such as Purdue’s Field Guide ($12.99), University of Arkansas Corn Advisor, University of Kentucky Corn Production, and one private groups MFA Agronomy. Each of these guides are quality apps and should be chosen based upon geography or personal preference. The university apps mirror their respective hard copies however UK’s app added a nice update section highlighting local Ag news. MFA’s app is strong in pesticides with good herbicide performance data.
For any producer who regularly applies animal waste the Manure Calc by the University of Nebraska is a great tool. The University of Wisconsin has a nice app in N Price Calculator and the Saskatchewan Soil Conservation association (SSCA) has created a nice fertilizer blend app. Oklahoma State University has Ammonia Loss Calculator which uses soil pH and environmental conditions to estimate N losses from surface applied urea.
I am also getting into the app game with two recently released apps the Canola Starter and Field Guide. Canola Starter provides a recommendation for safe starter rates based on row width and fertilizer source. Field Guide is app version of my Nutrient Management Field Guide, this app includes a nutrient removal calculator, nutrient deficiency ID tool, and fertilizer rate calculators. Along with these I have several in the wings with titles like Crop Nutrients in Irrigation, GDDs>0, and Wildlife FoodPlot.
As mentioned in my first two blogs the University of Missouri’s IDWeeds app was the first taxonomy based weed identification tool. I still use it regularly but both BASF and Monsanto have brought products to the table, both named WeedID, that are very user friendly and effective. Plant Images ($5.00) is a library of nutrient deficiency photos from a large selection of crops. Years and Ag PhDs also have apps available with deficiency images named Yara Checkit and Crop Nutrient Deficiencies. Cereal Disease ID app by BASF is intended for the UK and DuPonts Pestbook for Australian cotton farmers but I find that both can be very useful even in Oklahoma.
Pay to Play, Registrations
I have heard several good things about many of these apps. However they reguire the user to either be an employee or patron of the company or online registration. In a pay to pay app I would expect an all inclusive tool that could replace several free apps and preform record keeping duties.
To be honest this is not a section I use much as I do not have an operation to maintain records on. However just by walking through the apps Crop Calculator by the University of Wisconsin and Pesticide Recordkeeping (PeRK) by University of Nebraska.
This section has apps that I classify as decision aid tools that could be used by someone scouting crops and apps that can be used to map and or collect field notes. South Dakota State has two great tools in Soy Diseases and NPIPM Soybean Guide. Scout and Sirrus.
Company based, Pioneers app products are some of the best with Plantability and Estimator
Some things haven’t changed I still use Tank Mix Calc and Spray Select on a very regular basis. But over the past year a few companies have added product finders and Clemson University has released a very nice sprayer calibration app named Calibrate.
The last two apps are Mesonet and Climate Corp Basic. You will notice the background on the screen shot is slightly different. That is because neither of these apps is kept Ina folder, both are on my home screen. Whether it is rain, temp, or wind weather impacts all aspects of agriculture therefore these two apps are always within one tap. For any producer in Oklahoma the Mesonet is an amazing system with 120 automated weather stations spread evenly across the state. This app just provides this data with just a few swipes of the finger. For those outside of Ok Climate Basic allows producers to first save field of interest and then monitor rainfall and environmental conditions of each field. While not extremely accurate it is defiantly close enough for those with a wide territory to be a very handy app.
For more information and some screen shots of the apps in action either visit my website http://npk.okstate.edu/presentations or my YouTube site http://www.youtube.com/osunpk under the playlist OSU_NPK on Sunup.
Since my Ag App post in July I have presented on the topic an additional five times and have two more on the books for 2014. A good thing about doing talks is that you have to update the information to remain current. Which in all honesty, when it comes to technology of any kind this is quite challenging and even more so for Smart Phone Apps. In July when I first blogged on the subject I had 76 apps on my iPad. Today (1.3.14) I have 111 apps on my iPad, for both the iPhone and iPad, that I deem to be Ag related. Since the summer I have found new favorites, changed some, and added categories but for the most part I still maintain my 2 minute rule stated in the first blog. I have allowed a bit more leniency in that I now say “If I cannot figure it out in 3 minutes it’s GONE. An app should be intuitive, easy to use and have a purpose. They only exception to the 3 minute rule is the Scouting and Mapping Apps. Because of their complexity I allow them 5 minutes, and then I am done. Any app with GIS in its name gets much more time” I guess I am just getting soft.
Again I must make the obligatory statement; I am not a developer, designer, or expert. I am just a user who has had a chance to look at a few apps. Almost all of the apps I have are free and I am sure I have missed a few. Please share those with me. I am also not discussing Mobi’s, this is another large group of quality decision aid tools. I am also not discussing none apples apps. This is not because they are not relevant or important, it is because I do not have that technology.
I now have nine Ag folders on my iPad:
Ag News/Weather/Markets, Scouting/Mapping, Record Keeping, ID Tools, Crop Tools, Calculators, Sprayer/Chemicals, Fertilizer, Seed Select.
Apps are nice because the majority are stand alone and do not need internet or cell connection. This means they can be used when you are in the middle of nowhere, which is a great deal of Oklahoma, and have no service. This will exclude many of the Ag News/Weather/Markets, Scouting/Mapping, and Record Keeping apps that need positioning or location information.
Now let’s discuss some of the new and old apps.
Not much change in this group however I have added one or two.
This category has changed the most. Record keeping apps have been removed and several new apps added. The only free apps which can create boundaries are still Scout and Sirrus. To date Scout remains to be my favorite app for in field scouting notes. Pictures tagged with Lat Long and a note is very useful. My knock on is app is its boundary creation. It is a challenge every time as it is hard to remember the steps and not make a mistake. That is where Sirrus comes to play, by far the best boundary creation app. Sirrus has easy to use tools for both point and pivot boundaries. I like the edit vertex zoom in tool that resembles a rifle scope. I was able to add 12 fields in a matter of 20 minutes. Being able to create grid soil sampling scheme and record samples is also a very nice tool. My favorite part of the app, the UNDO button, and all apps should include this. The drawback to Sirrus is that it has no ability to take notes such as Scout. An additional nice scouting tool is South Dakota States NPIPM (North Plains IPM) app. This app provides not only a pest id tool with morphological drop down, I will discuss this in the ID Tools cat, but also management recommendation for the identified insect.
The majority of the apps in this category are “Pay to Play”, which makes since as they deal with data management and storage. Many would also fit the Scouting/Mapping category. As I do not pay for many apps I do not have experience with any of these. However this is the category that I would recommend any group to look at as they should be the all-inclusive app. However, PeRK by the University of Nebraska is a free app designed for field records of pesticide applicators.
I have added a few apps to this category but my favorites have not changed. I regularly use Plant Images, ID Weeds, and the Pestbook as references. I will add more discuss to app ID tools. The importance of being able to ID weeds and Pest via morphological drop down menus (ID Weeds and NPIPM) is extremely important. Many of the ID tools just have pictures and names. Well is I am using an ID Tool I likely do not know what I am looking at or what it is called.
Crop Tools includes my second “Paid in Full” app. And this one hurt a bit more. Not because it cost money but because I have multiple versions of the hard copy. However Field Guide by Purdue is one of my most recommended apps. Field Guide is the electronic version of the Purdue Corn and Soybean Field Guide, which the majority of consultants in the Corn Belt likely have this sitting in their truck. The Stoller apps also have nice very nice image bank of plant developmental phases. FieldGuide and CornAdvisor, another good app, are great examples of what I expect to be coming out of the majority of the Land Grant Universities very soon. Cooperative Extension has hundreds if not thousands of quality hard copy publications just waiting to be turned in to handy dandy apps. To be honest I am working on turning my Nutrient Management Field Guide into an app right now.
Only two apps has been added to this category. I am still using Fert.Removal, HarvestLoss and Growing Degrees on a regular basis.
Many apps have been added to this group but none of them have been good enough to kick TankMixCalc and SpraySelect of my favorites list.
Similar to the Sprayer/Chemicals category several apps have been added to this group, including several from Ok State. For me the Fert Cost Calc is still very useful. I do not get to use the Manure Calc I am very impressed by its layout and user friendliness. This app allows for applicator calibration, nutrient recs and manure value estimator.
It is no surprise the apps in this category are company created. I will say for the central Great Plains Pioneer’s Canola Calc is very useful tool for selecting canola planting rate providing input for row spacing live plants, seed weight, Germ percent, and survival percent.
To wrap up this blog I want to share with you may new Favorite none ag app. Bump is a huge time saver for anyone who takes pics with your iPhone or iPad. Bump allows easy transfer between mobile devices but more importantly between your mobile device and desktop by a simple tap of the space bar. This file share will go both directions. This means no more emailing pictures from your phone so that you can have them on your desktop. Bump is a iPhone app that can work on the iPad.
When searching with an IPad, remember to switch the search to include IPhone apps, there are some good ones out there that are IPhone only. Check out www.npk.osktate.edu/presentations to see screen shots from many of my favorite apps.
So I am going to approach a subject in this blog that is Not in my wheelhouse. At the first of the year I was asked by a friend to speak on Ag Apps at the 2013 InfoAg meetings. His thought was, hey this guy teaches Precision Ag and uses a IPad, he must know apps. Well, not so much. From January to the day before the talk in July I spent a great deal of time scouring the App store and working, my wife described it as playing, on my IPad. At info Ag I gave two talks, at the time of first talk on Tuesday I had 53 Free apps (1 paid), by the next morning and my second talk I had 60.
Since the meeting I have had numerous request for the slides and etc, so I thought this would be a good opportunity for a blog. Since InfoAg (7.17.2013) I have picked up even more apps, the total is now 76. However many of the new apps require registration.
On my IPad I have organized the apps into 8 basic folders:
ID Tools, Calculators, Seed, Sprayer/Chemical, Fertilizer, New/Weather/Markets, Scouting, Ag Apps (apps I don’t know what to do with).
While I have 76 Apps I of course don’t use them all. What follows is basically my Editors Choice from each group. Please note I have not had the time to work with all 76 Apps. And I am by no means an expert in Apps or the use of them.
I do have a basic require of any App I use. If I can not figure it out in 2 minutes its GONE. An app should be intuitive, easy to use and have a purpose. They only exception to the 2 minute rule is the Scouting Apps. Because of their complexity I allow them 5 minutes, then I am done.
This Category holds the One and Only App I paid for, Plant Images, a library of Nutrient Deficiency photos. I mean I am a Soil Fertility guy.
I regularly use Plant Images, ID Weeds, and the Pestbook as references. ID weeds is a true ID tool as you can use attributes to ID your weed, while the other two are visual reference tools.
I personally use the two Nutrient Removal Apps the most, but after the latest update AG-PhDs Fert. Removal has become my favorite as it allows you to entire any yield level.
Harvest loss is also a handy App that lets you put $ to combine inefficiencies.
This group contains two of my first Ag Apps and most frequently used.
Being a fertilizer guy herbicides are not my forte however I use the often.
TankMixCalc and SpraySelect has been in my App arsenal from the beginning.
The nice item about many of the Sprayer Apps is the ability to save/store mixes or provide record keeping.
Now the Fertilizer Apps are right up my alley. But the only ones I use are the Cost Calcs. As far as fertilizer recommendations go you must remember they are quite regionally specific so the Wisconsin Corn N rate Calculator does me little to no good.
This is the category that I have the most apps. My first was Agriculture (DTN/PF), so I fall back to it often but I also like AgIndex and AgWeb. With the news/marketing ext apps the biggest key is find one that a) reports on topics of interest to you, they do differ and b) has a layout and design that is easy to use and enjoy.
The Scouting tools are a bit different, most but not all require registration of some kind. I like most that I have tried but each has their own high and low points. The use of a scouting tool will be highly dependent upon uses, goals, and what companies you currently work with. For example Field Notes 360 has some nice points, you can make notes on photos, but you have to be a Pioneer employee or customer to get full use, I like Scout (Connected Farm) note taking capability and the fact you can input GreenSeeker NDVI values. I have the beta version of Sirrus but I can all ready tell you it is shaking out to be my favorite. Two wins for Sirrus, its method of creating and editing boundaries is top notch but what I like the most is its ability to set up a direct grid sampling.
I don’t expect any app to change my life or yours, but it may make it easier.
The ID Tools, Calculators, Sprayer/Chem and Fertilizer apps are nice when I am in the field with a producer and just break out the IPad for easy demo/explanation.
There is a multitude of apps available and more being produced every day. Just as everything else find what suites you regardless of others opinions. When searching with an IPad remember to switch the search to include IPhone apps, there are some good ones out there that are IPhone only.
