Precision agriculture is evolving — and SWAT MAPS is right at the forefront.
Farming Smarter with SWAT MAPS
Not all parts of a field are created equal—and that’s where SWAT MAPS come in. Instead of treating the whole field the same, SWAT MAPS help farmers understand the natural variability across their land so they can farm more efficiently.
How It Works:
-A specialized vehicle with a SWAT BOX collects data on soil, elevation, water flow, and organic matter.
-An agronomist confirms the data by sampling the soil (“ground-truthing”).
-The field is divided into 10 productivity zones:
Zone 1-2 (Driest): Sandy, hilltop areas.
Zone 3-4 (Upper slopes): Water-shedding ground.
Zone 5-6 (Average): Balanced mid-slopes and flats.
Zone 7-8 (Lower slopes): Toe slopes and wetter flats.
Zone 9-10 (Wettest): Heavy clay or low-lying areas.
Why It Matters:
By knowing exactly where the wettest, driest, or most productive soils are, farmers can make better decisions:
-Variable-rate fertility – apply nutrients only where needed.
-Variable-rate seeding – adjust seeding rates to match soil potential.
-Soil amendments – apply lime, gypsum, or ash more precisely.
-Variable-rate irrigation – optimize water use across zones.
The result? More efficient farming, healthier crops, lower costs, and reduced environmental impact.
