FIELD SPECIFIC MANAGEMENT ZONES

Most variable rate maps use simple grid sampling or a single data layer. Premium Ag’s approach is fundamentally different.

We fuse 10+ data layers — Sentinel-2 vegetation indices (NDVI, NDRE, EVI, SAVI, NDWI), Veris soil EC, and LiDAR-derived terrain parameters like slope, wetness potential, elevation, and curvature — and run them through advanced ML algorithms (K-Means, Fuzzy C-Means, PCA) to find natural groupings.

The result: irregular, organic zones that follow real soil and terrain boundaries, not arbitrary rectangles. Intensive research verified strong trends in soil texture, nutrient content, and organic matter between zones.

Variable rate seeding proven by the data

Premium Ag ran multi-year field trials with thousands of plant count locations to design zone-specific seeding rates using a statistically valid procedure.

The finding: in low-potential zones (high salinity, poor moisture), plants and yield won’t increase past a certain rate, mortality climbs significantly. You’re paying for seed that dies.

Meanwhile, zones with high moisture and organic matter support higher populations and respond strongly to increased seeding rates.

The result: seed every zone at its optimum, not too much, not too little.

Key insight: Zone 1 yields barely change regardless of seeding rate (58 → 56 bu/ac). Zone 4 responds strongly — jumping from 94 to 126 bu/ac with higher rates.

Why it matters: In Zone 1, nearly 4 out of 10 plants die at high seeding rates. You’re paying for seed that never produces a bushel.
