Innovative Technologies for the Efficient Use of UAN Liquid Fertilizers: Production, Logistics and Application in Case of Lack of Moisture and Global Warming

The article presents the results of scientific and industrial studies of the effectiveness of liquid nitrogen and nitrogen-sulphur-containing mineral fertilizers based on the carbamide-ammonia mixture of UAN when feeding potatoes on irrigation during irrigation-fertigation. The studies are relevant in that during irrigation for feeding potatoes with nitrogen (UAN-32) and nitrogen with sulfur (UAN + S), when nitrogen, represented by three forms, has a prolonged effect, providing a longer time for nitrogen use by plants. The innovative technology of feeding potatoes with fertilizers based on UAN provided an increase in yield from 6.4% of marketable potatoes and up to 12.2% of the total yield. Today, Russia has everything necessary for the effective use of innovative fertilizers based on innovative technologies: chemical plants for the production of UAN fertilizers with volumes sufficient for processing crops on an area of 35 million hectares with a rate of 100 kg/ha; UAN using all technologies known in the world, the logistics of transportation and storage of UAN has been developed and technically provided.
