Recently patented acid fertilizer technology has led to the development of a family of non-phytotoxic foliar nutritionals with high levels of soluble essential secondary and micro-nutrients called Harvest Plus. Regular applications to cotton increases flower and fruit set, improves drought tolerance, reduces shedding, and provides for shorter internodes and more compact plants. A positive synergistic relationship was observed between plant nutrition and Pix in South Carolina field tests and provided for a 28% yield increase.

The composite sample, of a field soil sample represents a soil that does not exist. It is merely an average for the whole field. Nearly all fields contain several different soil types, some contain many. If we treat the whole field the same, we will not have the correct treatment for any of the soil types.
