Many soybean planters being purchased by farmers today are equipped with the ability to vary the seeding rate as they go across the field. The idea of variable rate planting in soybeans may allow farmers to fine tune their plant populations based on management zones within a field. The foundation of the variable rate is that highly productive soils may produce adequate yields with lower plant populations and medium to poor productive soils may need higher plant populations to optimize yield. Previous studies with B&M Crop Consulting have shown an agronomic and economic improvement with variable rate soybean planting across management zones, but some environments seem to respond to higher...
