Variable Rate Mapping
Services
- Variable Rate Mapping is a fairly simple
process of taking an image from a field and creating zones
based off of this input image.
- Input maps can come from many different
sources, Satellite or Aerial Images, Yield Maps, Veris Maps,
Grid Soil Samples, Grower Defined Areas and Soils Maps to
name a few possible sources.
- From these maps there are basically two
types of maps we produce, Fertilizing and Seeding.

Variable Rate Fertilizing
- Fertilizing can be N-P-K,
Micro-Nutrients, Lime or Manure applications.
- Images will typically be adjusted to 3 to
5 zones for soil sampling.
- Yield goals set for each zone.
- Zones are soil sampled.
- Variable Rate Application maps created.
- Cost - $1.50 / Acre (Maybe
added charges if images need to be purchased)

Variable
Rate Seeding
- For use in Variable Rate Seeding or
Variable Variety Seeding. Application rates can be set to
minimal zone rates as below or interpolated rates like the
fertilizer map above.
- Zones are normally established off of the
Growers and/or Consultants knowledge of the field and the
crop being planted, previous years yield maps are
preferred.
- Once the zones are established, seeding
rates set.
- Variable Rate Map will be created.
- Cost - $1.50 / Acre (Maybe
added charges if images need to be purchased)
