Yields and Nutrient Removal
As we focus on SOIL FERTILITY fundamentals, higher yields equal to higher nutrient removal. Harvesting a crop removes nitrogen (N), phosphorus (P), potassium (K), and other popular macro & micronutrients from the subsequent cropping oil productivity which require replenishment to maintain soil productivity for subsequent cropping seasons.
One way to shift your focus toward fertilizer fundamentals is by creating a crop nutrition plan for your operation. A major component of that includes SOIL TESTING. A soil test provides a starting point for developing a well-through out plan.
