HIGH YIELD WHEAT NUTRITION IS SITE-SPECIFIC

Nutritional needs of high yield wheat can seldom be provided by soil reserves alone. Mineral fertilizers remain excellent sources to supply nutrients anticipated to be in short supply. They provide a nutrient delivery system in tune with wheat growth stage needs and that is compatible with a safe environment.

Soil tests provide a good measure of soil pH and nutrient status. Careful sampling is critical as variability exists in every field. Thus, site-specific nutrient management delivers nutrient needs based on (1) differing soil fertility and productivity levels, (2) yield goal expectations, and (3) supporting production practices which interact with the basic functions performed by specific fertilizer nutrients. Such a system adjusts for differences in soil productivity and provides optimum development of the crop’s yield potential for each management zone in a field.

The building blocks for high wheat yields are no mystery. The challenge comes with the readjustment of the blocks to build the best production system for each management zone in the field. Each of the following practices contributes most when properly teamed with the others, and where needed, adjusted for management zone differences.
