Nutrient status of leached chernozem under sugar beet depending on doses of mineral fertilizers

Abstract

Intensive technology for cultivating sugar beet requires the introduction of high doses of fertilizers, but studies show that they do not have an advantage over the average recommended doses, and an excess of fertilizers can lead to an increase in the cost of their application and deterioration in product quality. The studies were conducted under the conditions of stationary experiment at the Department of Agricultural Chemistry and Soil Science in Voronezh State Agricultural University. The article reveals the influence of long-term application of mineral and organic fertilizers on the content of available forms of nitrogen, phosphorus and potassium, as well as yield and sugar content of root crops. It was found that at the beginning of the growing season the greatest content of available forms was provided by the application of N240P240K240 against the background of the aftereffect of manure - 182.3 kg/ha of mineral nitrogen, 165.7 mg/kg of mobile phosphorus and 159.8 mg kg of exchangeable potassium. When applying N120P120K120 against the background of manure, the content of the fertilizer element was less. In fertilized variants, a reliable yield increase was obtained during all the years of research. A double dose of mineral fertilizers (N240P240K240 against the aftereffect of manure) did not give a reliable increase in yields compared to a single (N120P120K120 against the aftereffect of manure). In the same variant, there was obtained the maximum sugar yield -9.0 t/ha. The experiment with a double dose of fertilizers was less effective.
