What is Precision Ag?

Precision Ag is a farm management concept based on observing, measuring, and responding to inter - and intra-field variability in crops. This is also known as Site Specific Crop Management. 

Why Precision Ag? 

Precision Ag tools provide quick and efficiently ways to observe and precisely manage your fields! 

Precision Ag Products and Services:

  • In-Season Imagery (geo-spacial imagery). There are two methods that can be used to obtain this imagery:
    • ‚ÄčDrone scouting:
      • NDVI (Normalized Difference Vegetative Index) images.*
      • High Resolution "Visual" Images: provides a high resolution picture of the field.
    • R7® Tool by :
      • In-season NDVI (Normalized Difference Vegetative Index) Satellite Images.*
      • Bare-Earth Satellite Images.
      • Historical Peak Vegetative Growth Images.
      • Can be used to generate VRT prescription maps.
*NDVI can be used to evaluate the health of plants that are growing by providing a scale that measures the photosynthetic activity which is occurring within a field. Areas with less photosynthetic activity, measured by a lower NDVI score, can be scouted to determine the cause of the decrease in photosynthesis.
  • Agworld Farm Management by : Ag World allows crop advisors to assist growers in record keeping, by allowing growers to convert recommendations from the crop advisors directly into as applied records. Minimizing the need for double entry. Spend more time in the field, and less in the office.
  • Variable Rate: Variable Rate Technology allows growers to begin to manage the variability that exists within fields:
    • Variable Rate Fertilizer:**
      • Variable Rate Fertilizer can address the variability in fertility within a field by placing more fertilizer where fertility is lacking, and less where fertility is plenty.
    • Variable Rate Seeding:**
      • Variable Rate Seeding can be used to address plant stand variability, to promote uniform stands.
    • Variable Rate Irrigation:**
      • Variable Rate Irrigation can be used to address the variability in water holding capacity that can exist within fields.
**Variable Rate Technology requires a geo-spatially referenced data layer, that can be used to then generate a prescription to deliver the correct amount of fertilizer, seed or water over a given portion of the field. The geo-spatially referenced data layers can come from:
  1. Grid Soil Sampling (Generally 2 acre grids)
  2. EC Soil Mapping
  3. Bare Earth Satellite Imagery (Winfield R7 tool)
  4. Historical Peak Vegetative Growth Images (Winfield R7 tool)
  5. Elevation Maps
  6. Yield Monitors
  7. Geo-spatially referenced images (drone images, images taken by an airplane or by a satellite)
  • EC Soil Mapping: Soil EC Mapping is a way to measure soil texture. The EC (electrical conductivity) of a soil correlates strongly to soil particle size and texture. Sandy soils have low conductivity, and clays have high conductivity. Knowing the texture makeup of your fields has several advantages. Soil texture affects: Water holding capacity, cation exchange capacity, drainage, nutrient leaching, and nutrient retention and supply. Different soils have different capacities for producing crops. Knowing the texture of your soils is a starting point to optimizing your inputs and maximizing your yield.
