Soil, Water, and Topography (SWAT) Maps are high-definition zone maps of soil potential. SWAT Maps are the foundation of all variable-rate fertilizer and seed applications and enable service providers and their growers to better understand field variability in order to optimize crop inputs and profitability.

Soil-Based Zone Maps


Factors such as salinity, soil textures, soil organic matter levels, and topsoil depth all impact yield and fertilizer response.


Water is the most profound influence on yield and fertilizer response. SWAT Maps delineate dry (knolls) versus wet (depressions) areas of the field into zones for proper management.


Topography describes landscape position (knoll, midslope, depression) and influences moisture, erosion, organic matter levels, pH, and soil fertility levels.

What Our Partners Say

Tyler Kessler

Kessler AgVentures

“My confidence in how the zone maps are made as well as the agronomy behind mapping, zoning, prescribing, and technical support are second to none in the VR industry. SWAT Maps are my first and only choice for mapping fields and creating VR prescriptions for the clients I work with.”

Jason Schley

Next Level Ag

“All good decisions come from data, without a good base layer map being the foundation for good decisions on any operation there are to many decisions made from testimonials not data driven off of the farm.  SWAT is the answer to getting an operation more in tune with making proper input decisions.  We need this layer of decision making for yesterday, today and tomorrow!”

Jonathan Zettler

Fieldwalker Agronomy

“Precision ag isn’t just a once and done. It’s a constantly evolving process. That’s part of what attracted me to SWAT Maps. It’s a systematic process to building seed or fertilizer response zones. It’s repeatable; you go and do it once and then you’ve got management zones to work with. The map is just the starting point. We use it to identify opportunities where we will get a response.”
