Scouting App Review

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.

List of all apps downloaded for the review.

After I gained access I went into iTunes and Google play to determine where they could be found.

Mobile devices applications are available for.

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.

Home work space. Laptop for web applications, iPad mini for app review, iPhone and notebook for in-field notes.

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.

If a web or desktop based program was needed to direct actions I categorized the application as best fit for larger consulting groups.

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.

This table shows which mobile applications can apply field boundaries from the device, which applications utilize CLUs (common land units) and shape files.

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.

Agrian Field boundary draw tool.

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.

Field boundary building utilizing common land units (CLUs). Often this was a very nice feature.

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.

Field boundary building utilizing common land units (CLUs). Just as often this feature did not work for the fields I wanted.

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.

This table list the applications which the crop information (crop type, variety/hybrid, population and planting date. The table also list the applications which had access to SURGO soil type data.

 

FarmLogs brought SURGO data directly into the application.

 

Climate provided fields dominate soil texture, estimated OM%, pH and EC.

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.

This table shows the weather and forecast features on the mobile and desktop applications.

 

Sirrus shows current weather on the fields home screen with the option to look at hourly and 10 day forecast along with historical precip data.

Climate provides current weather, hourly and 6 day forecast along with seasonal weather data based upon field planting date.

FarmLogs scouting app graphed the rainfall and GDD heat unit accumulation over the growing period

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.

This list shows the scouting functions of the applications reviewed.

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.

The Open Scout layout during scouting was quite clean.

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.

Aker Scout had images with each of its pest options.

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.

Scout Pro takes users through a ID tool to help select proper pest.

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.

This table list the applications with can create management zones, send VRT files, and have access to satellite imagery.

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.

 

Agriculture Apps, 200 strong and growing

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.

Coverslide

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

Ag News

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.

 

Ag Resources

Ag Resources

This includes peer review publications, resource guides and extension materials.

 

Calculators

Calculators

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.

 

Crop Tools

Crop Tools

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.

 

Fertilizer

Fetilizer

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.

OSUNPK

OSUNPK

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.

ID Tools

ID Tools

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

Pay To Play

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.

Records

Records

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.

Scouting/Mapping

Scouting_Mapping

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.

Seed Select

SeedSelect

Company based, Pioneers app products are some of the best with Plantability and Estimator

Sprayer Chemical

Sprayer_Chemicals

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.

Weather

Weather

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.
