Think DifferentThe South Central Co-op at Lacona, Iowa, is promoting a more science-based approach to applying nitrogen fertilizer on corn to its member farmers. In the first year of its new Sustain platform, 28 farmers signed on to apply no fertilizer last fall, only a base amount at planting, and more N as needed in split applications during the growing season as recommended by the Adapt-N modeling tool. The goal is to apply only the amount of nitrogen the corn crop needs, when the corn plants can use it, for optimal yields and minimum nitrate loss to tile and waters downstream.
