Higher Crop Yields Result In Greater Nutrient Removal: The more plant material that is removed, the more nutrients are removed.
Current Practices Have Removed NPKS (Nitrogen, Phosphate, Potassium And Sulfur) As Limiting Factors: For years the main emphasis has been on nitrogen, phosphate, potassium and sulfur, without the addition of micronutrients to the soil.
Fertilizers Have Been Refined: As recently as 30 years ago, many of the NPK fertilizers contained micronutrients as impurities. Technological advances in purifying fertilizer have resulted in their removal from NPK.
Better Varieties Have Increased Yield Expectations: As varieties yield potential improves, the "Law of the Limiting" rule becomes more important
New Crops: Each crop grown requires a different balance of nutrients. As growers introduce new crops to their rotations, they may also increase the need for micronutrients in their soils.
Processors Quality Demands: A properly balanced nutrient profile will help increase the quality of your crop, thus making it easier to meet the higher demands made by processors and end-users.
More Research: An increasing body of research is justifying the need for balancing all nutrients available to your crop, both macro and micro. It is also giving producers a better understanding of when the crop needs the nutrients within its growth cycle.
