TECHNICAL AND TECHNOLOGICAL APPLICATION OF LIQUID NITROGEN AND NITROGEN-CONTAINING FERTILIZERS ON THE BASIS OF KAS-32 IN SEEDING CEREAL AND GRAIN LEGUME CROPS

The article presents materials from the laboratory and field studies of the Samara State Agrarian University on the effectiveness of liquid mineral nitrogen and new nitrogen-sulfur fertilizers based on KAS-32 compared with solid fertilizers – ammonium nitrate produced by PAO KuibyshevAzot (Tolyatti, Samara oblast) in the cultivation of cereal crops (durum wheat ) and legumes (soybeans) using MINI-TILL technology provided by the agricultural machinery complex AO Evrotehnika (Samara) of the German company AMAZONEN-Werke (Germany). Objective: to determine the effectiveness of nitrogen liquid mineral fertilizers produced by PAO KuibyshevAzot and new nitrogen-sulfur fertilizers in comparison with traditional solid mineral fertilizers – ammonium nitrate – with the determination of the optimal doses, methods and time of application, the necessary technical means for various crops, including cereals and legumes. In the dry year of 2018 (the seventh drought year since 1936), fairly high results were obtained in terms of yield and quality of the products when using KAS-32, KAS-32 with sulfur and RPS (sulfur-containing nutritious solution) in comparison with solid mineral fertilizers (ammonia nitrate) when applied by AO Eurotechnika sprayers equipped with large-droplet sprayers and extension hoses for foliar and nonroot (root) dressing of plants.
