We have really been trying to push yields in these fields, but with conventional soil sampling, we weren’t getting the yields we wanted.. When we applied potash VRT on 2.5-acre grids according to the moist samples, we were applying more in the areas where it was needed. We saw yields climb dramatically, up to 260-270 bu. in areas where we had never seen those yields before. It is tough to tell, but we expect a 5% yield increase with field-moist sampling over conventional dry.”
