The influence of new types of enriched fertilizers on crop productivity and agrochemical properties of soils

Abstract

The effect and aftereffect of new types of enriched sulfur-containing fertilizers on the productivity of spring wheat of the Novosibirskaya 31 variety and peas of the Radomir variety, as well as the agrochemical properties of leached chernozem and agro-gray soil of the Krasnoyarsk forest-steppe, characterized by an acute deficiency of mobile sulfur, were studied. It was found that the application of fertilizers containing sulfur statistically significantly increased the increase in productivity of pea biomass in the year of application. With the aftereffect of spring wheat, an increase in productivity was noted on leached chernozem; the aftereffect of fertilizers for wheat on agro-gray soil was not effective. The application of enriched fertilizers did not affect the acid-base balance of soils. In chernozem leached in all fertilized variants, the supply of mineral forms of nitrogen is high, while the content of mobile sulfur increases. The supply of nitrate and ammonium forms of nitrogen in agro-gray soil is low, and the amount of mobile sulfur does not increase.
