Reduce nitrogen fertilization by 25% without reducing yields

A cost of €42/ha on cereals “No loss of yield or change in nitrogen concentration in grains was observed under nitrogen fertilization, following the application of FertiRoc, for either wheat or maize.
Thus, even when grain production increased, there was no dilution of nitrogen concentration, an important result with regard to the qualitative value (= protein content) of wheat and maize grains”, details the Official Journal of Swiss Agricultural Research.
