How it works

From a field boundary to a file the cab can load

Varigro builds variable-rate fertilizer and seed maps without yield monitor history. You set the rails, review the map, and load the file.

Get started For growers

What goes in

  1. A field boundary. Upload a shapefile or draw it on the map.
  2. The crop and yield goal: corn, soybeans, or wheat.
  3. The fertilizer grades and prices you pay, or the seed population, and the minimum and maximum for each.
  4. Soil tests you already have. They are optional.

Build the map

  1. Imagery and layers

    Varigro reads up to ten years of Sentinel-2 crop canopy on the field, Sentinel-1 spring radar, CHIRPS rainfall, USGS 3DEP elevation, and USDA SSURGO soil and land cover. The field is split into 100 ft cells, and each cell gets those layers. See Data sources for citations.
  2. Productivity rank

    Each cell is ranked by expected productivity, mostly from how the canopy has performed, with dryness, spring wetness, and slope. Growers see that rank as yield potential: a percent of the field's best ground.
  3. Management zones

    Cells that behave alike join into connected management zones. Zone 1 is the highest productivity ground. You can hold a zone at a flat rate.
  4. Prescription

    The rank places each acre between the minimum and maximum you entered, so the map stays inside a program you would apply. Fertilizer is the product rate. Seed is seeds per acre. Sloughs, water, and trees can be skipped. A fertilizer map compares with your flat rate in dollars per acre. You review the map and approve it.
  5. Export

    Varigro writes one shapefile ZIP per product for Raven Slingshot, John Deere, Ag Leader, Trimble, or a generic USB shapefile. ISOXML and John Deere Operations Center push are not supported.
  6. Apply and record

    The rate follows the zones across the field. The season plan schedules fertilizer for fall, spring, or at plant, and seed on its own. A co-op packet and the zone and season reports cover the fertilizer you scheduled.

Pricing is $3/ac per year. Get started to see it on your acres.

What Varigro does not do

  • Your rails

    It does not set rates from a fertilizer recommendation table. The map is a productivity rank inside your rails.

  • Seed savings

    Seed maps do not include estimated dollar savings. They are seeds per acre inside the population you set.

  • Agronomist

    It does not replace your agronomist. Many growers review the map with one before they apply.
