Nutrient management is critical in order to increase or maintain crop yields. To meet crop needs throughout a growing season soil fertility must be consistently high. For proper growth and to achieve good yield, plants should receive fertilizers that meet their nutrient requirements because each crop extracts nutrients from the soil at different levels. Crop-specific or blended fertilizers are produced based on the specific crop nutrient requirement and provides the required essential nutrients in optimum proportions resulting in improved quality and enhanced yields.
