Mobile Apps and Online Tools

New apps and online tools are being developed on a regular basis to help producers with farm management decisions.  The table below includes info and links to apps related to fertilizer application, crop nutrition, soils, equipment, record keeping and more.  This table will be updated as more tools become available.

Clermont Soil & Water Conservation District’s Fertilizer Recommendation App (FertRec) is a fast and easy way to determine your fertilizer and lime needs based on soil test data. The FertRec app’s recommendations are based on formulas used in the Tri-State Fertility Guide.Clermont Soil & Water Conservation District’s FertRec app is a fast and easy way to determine your fertilizer and lime needs based on soil test data. The FertRec app’s recommendations are based on formulas used in the Tri-State Fertility Guide.

To use the app, follow these simple steps:

1. Select your planned crop from the pull-down menu (corn, soybeans or wheat).

2. Input your average five-year yield for that crop in bushels per acre.

3. Select your previous crop from the pull down menu.

4. For lime recommendations, select either 6.0, 6.5 or 6.8 as your target pH.

5. From your soil test report, enter your soil test data:

a. Enter soil pH

b. Enter buffer pH

c. Enter cation exchange capacity (CEC)

d. Enter the soil phosphorus level in ppm. Important: Select either Bray or Mehlich as the phosphorus test used. Phosphorus recommendations will be incorrect is the wrong test type is selected.

e. Enter the soil potassium level, in ppm.

6. Hit the “Click Here for Recommendations” button.

Precision Agriculture

The term “Precision Agriculture” refers to the use of modern technology in managing operations. Global Positioning Systems (GPS), Mobile Implement Control Systems (MICS), and Global Imaging Systems (GIS) are used to collect data, run machines, and keep records. All of the information is typically collected and sent to Farm Management Information Systems (FMIS) to determine the capacity of crops the grower can produce.

Why Use Precision Ag?
  • Improve Soil Management by maximizing uptake and minimizing nutrient loss
  • Variable Rate Technology with Geo-referenced satellite imaging efficiently plants seeds and lays down fertilizer
  • Data Management Practices Improves yield by making predictive decisions based on previous seasons yield and comparative data.
  • Increase Crop Production and Quality
  • Better Management Costs and Efficiency
  • Better Environmental, Social, and Ecological performance

System Practices

  • Auto-Steer and GPS guidance uses GPS signals to automatically steer or guide a machine or implement. Various accuracies are available and can steer or locate machines and devices within a 1 inch to 2 foot repeatable position (Examples: RTK 1-2”, OmniStar 2-5”, WAAS 6-24”, GLONASS 6-24”)
  • Many of these steering or guidance systems are integrated directly into a MICS controller so a user can control and view different options for where and how these GPS positions interact with a machine, implement or device. GPS is also used with hand-held devices such as smart phones/tablets to show a specific location of a person relative to external data and maps.
  • Planter/Seed Monitors use GPS position to monitor location of seed population, overlaps, and skips while recording and controlling how, where, and when seed is planted.
  • Yield Monitors use GPS position, sensors, and associated electronics mounted on a harvester to quantify the yield for the crop being harvested on an instantaneous and averaging basis. The Yield Monitor data can be combined with the Plant/Seed Monitor data for effective evaluation of farming practices by soil type, variable rate application, nutrient program, etc.
  • FMIS (Farm Management Information Systems): System which visually coordinates and manipulates data mainly from agricultural practices as well as provides general record keeping management. Uses data from MICS controllers and Remote sensed data to create and manage valuable datasets to prescribe decisions and work orders to a field with a MICS controller.
  • Satellite imagery: Color RGB or infrared imagery taken from space (100-500 miles above the earth) to determine vegetative growth and patterns in a field.
  • Aerial imagery: Either color RGB or infrared imagery taken within airspace to determine vegetative growth and patterns in a field. (Examples: Planes, Unmanned Aerial Systems (UAS/Drones)
  • Ground: Used to measure temperature, moisture, EC (electro conductivity), PH, organic matter, etc.
  • Weather: Ground or satellite based equipment used to measure temperature, moisture, sun reflectiveness, wind speed, etc.
  • Mobile: A hand held device or mounted to an implement which records infrared, temp, nitrogen, PH, and other signatures from a plant or soil.
