Improvements in corn production technology using liquid nitrogen fertilizers

Abstract

The article is devoted to improvements in technology of corn production using liquid nitrogen fertilizers such as urea ammonium nitrate (UAN), in pure form UAN-32 or with the addition of sulphur UAN+S, with various methods of application before seeding or leaf-feeding dressings. This technology provides an increase in the corn yield with additional efficiency compared with the use of solid nitrogen mineral fertilizers like ammonium nitrate in conditions of insufficient moisture, which are typical of many regions of Russia and especially of the Volga region (Samara oblast).
