Optimization of plant nutrition using non-traditional organic fertilizers and zeolite-containing tripoli

Abstract

The problem of conservation and reproduction of soil fertility by using unconventional organic fertilizers, particularly the replacement of the mineral nitrogen fertilizer to its organic form is discussed. The growth of the livestock industry lays the groundwork for the recovery of meat processing industry waste of horned ungulate crumbs (HAC) as fertilizer for inter-tilled crops. HAC contains about 14% nitrogen. Experiments on the application of HAC as a nitrogen fertilizer and sorption-type ameliorant – zeolite-containing tripoli were organized in 2012-2016 in the crop rotation link on the light gray forest soil of the experimental field of the FSBEI HE Chuvash State Agricultural Academy, Chuvash Republic. In this paper, the effect of the HAC-form on the optimization of nitrogen nutrition of the studied crops both separately and for tripoli having phosphorus-potassium mineral fertilizers is studied. The positive effect of HAC and tripoli on the growth and development of potato and fodder beet plants, soil biological activity, leaf surface area, yield and quality indicators of potato tubers and fodder beet root crops both in the first year when fertilizers are applied and in their aftereffect in the second year for barley yield was revealed. The study materials contribute to the practical solution of the problem of the recovery of meat processing industry waste and rational use of resources in the fertilizer system, being a guide to energy and resource conservation in agriculture.
