“N is a big pollutant of water and with increasing demand on clean water sources, the use of excess N fertilizers is sure to come under increasing scrutiny and regulation. Scientific advances in crops that can “get by” with less Nitrogen are worth noticing! Do more with less impact will be an Agronomist’s mantra.”

Modern corn hybrids produce more plant material and take up, on average, the same amount of nitrogen as earlier varieties, in spite of being more crowded and having less nitrogen available per plant, a Purdue University review finds…read more.
