The paper presents the results of field and laboratory experiments in studying the effectiveness of zeolite of the Yushanskoye deposit based in the Ulyanovsk region being a fertilizer of maize on grain when applied both in pure form and in combination with mineral fertilizers. A positive effect of zeolite on the agrophysical, biological and agrochemical properties of medium-loamy leached chernozem and, as a result, yield and environmental safety of maize grain has been established. Its increase ranged from 0.93 t/ha (500 kg/ha of zeolite) to 2.43 and made up to 2.76 t/ha when used together with mineral fertilizers. when applying 500 kg/ha zeolite to the soil together with nitrogen fertilizer (urea) at the rate of 60 kg per hectare for 3 years on average the maize grain yield exceeded the option with mineral fertilizers (N60H60R60) by 0.27 t/ha. Zeolite contributed to more environmentally friendly products. |
