Reducing Applied N: Jake has cut his N-rates for corn in half over the past couple of years, from 220 lbs of N per acre to about 100 lbs per acre. “We totally switched our programming. We have NPK in the starter, but we are now more heavy on trace minerals and starter biology,” he notes. Jake plans to use a starter of 2.5 gallons per acre of CX-1, an organic biological concentrate, and 2 quarts per acre of high energy fish fertilizer made from whole fermented salmon, for nutrients.
