Increased biomass production is the major driving force leading to greater nutrient accumulation within the plant. Dr. Steinke has documented similar biomass production (lb/A) from seeding rates as low as 50,000 seeds per acre up through 170,000 seeds per acre. Additional recent research from Illinois and Wisconsin has highlighted the importance of season-long nutrient accumulation as grain tissues remobilized a majority percentage of N, P, Cu, and S to developing seed during grain fill. Much of the late-season nutrient uptake and partitioning to grain comes from the soil, emphasizing the importance of sufficient soil nutrient resources in the later reproductive growth stages to prevent...
