This is the wonder of modern agriculture. As our population increases, production efficiency through innovation and new technology has kept pace to provide us with a continuing supply of abundant and nutritious food. Fertilizer products and practices are important contributors to this success.
High yields come at a cost.
Yields of many crops grown today have doubled in just the past few decades. Such high nutrient demand requires skillful management to avoid yield limitations developing because of an induced nutrient deficiency. Nutrient uptake and nutrient removal are not the same. Nutrient uptake refers to all the nutrients taken up by the crop as it grows and matures. Nutrient removal, on the other hand, refers only to that portion of the crop actually hauled from the field.
