Abstract :

JSC “NIUIF”, the oldest (founded in 1919) and the only one in Russia scientific-research institute for phosphorus-containing fertilizers, developed a novel flexible technology of production of NPKS/PKSfertilizers of slow release with a controlled dissolution rate and nutrient assimilability into the soil solution. These fertilizers are environmentally safe, non-radioactive; practically do not contain compounds of harmful heavy metals (arsenic, cadmium, lead, mercury, chromium, etc.). Besides the main nutrients (nitrogen, phosphorus and potassium) they also contain sulfur and calcium in a plant assimilable form. The dissolution rate is regulated by changing the ratio between the water-soluble and assimilable forms of phosphorus, as well as by addition of ammonium salts. The technology is waste-free, moreover, it allows to process wastes and by-products of other production units: phosphogypsum, conversion chalk, cake from sodium tripolyphosphate production, sludge sand, etc. These fertilizers were successfully tested by the International Institute of Plant Nutrition and in the Russian Agricultural Academy named after K.A. Timiryazev and everywhere its high agronomic efficiency was proved. The technology is protected by three patents of the Russian Federation. Based on the design documentation developed by JSC “NIUIF” NPKS/PKS-fertilizer plant was built and successfully set into operation at Metakhim plant (Volkhov city, Leningrad Region).
