Soil, Water, and Topography (SWAT) MAPS are high-resolution soil foundation maps used to execute variable rate fertilizer, seed, soil amendment, pesticide, or precision water management. They are created using our patented process. Factors such as soil texture, organic matter, topsoil depth, and salinity can all impact yield and fertilizer response. Water has the biggest influence on yield and fertilizer response. SWAT MAPS categorizes dry and wet areas in your field into ten different management zones. Topography is described by landscape positions in a field (hilltops, mid-slopes, and depressions). Topography can influence soil moisture, erosion, organic matter levels, pH, and soil fertility levels. All SWAT MAPS are made up of ten zones. Having 10 different zones accommodates variability in your field.
