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.

Corn Grain Fatty Acid Contents in Response to Organic Fertilisers from Meat Industry Waste

“…Among agricultural wastes, meat and bone meal, a byproduct of the animal rendering industry, contains significant amounts of essential nutrients for plants, especially N, P, and Ca [28,29]. Several publications have presented the use of waste from the meat industry as a source of nutrients in crop fertilisation [30][31][32][33]. Our research evaluates the potential use of MBM in crop production, not only as a source of nutrients to improve soil nutrient abundance [34] but also to improve grain quality, elements often overlooked when evaluating applied organic fertilisers.…”

Direct effect and aftereffect of sapropel on agricultural crops yield and agrochemical properties of light grey forest soil

“…Numerous results of scientific research on the cultivation of agricultural crops using only organic fertilizers (semi-rotted manure, compost, peat), urban wastewater sludge, as well as by-products of the food industry and waste processing (liquid and solid products of a biogas plant, horn-hoofed shavings, bone meal, cake, etc.) showed their high economic efficiency [1], [2], [3], [4], [5], [6], [8], [9], [12], [ 19], [20], [21]. The research carried out in greenhouses showed that by-products of industrial production, i.e., products of a biogas plant, municipal wastewater sludge, etc.…”

Long-term aftereffect of dairy production waste on productivity and soil fertility

“…Disposal of waste from light industry around the world causes not only a burden on the environment, but also additional production costs. Wastes such as municipal sewage sludge, hoof shavings, biogas plant waste can be effectively used as organic fertilizers [1,6,7,8,12]. One of these wastes, or residues, of dairy production is cake -a hydrophobic viscous substance of light gray color with a sharp and unpleasant smell of spoiled cottage cheese.…”
