摘要：

Most tanneries and leather product manufacturers have serious problems regarding waste discharge, as their disposal in dump wastes leads to chromium accumulation in soil with possible harmful effects on the ecosystem. The use of untanned wastes presents a special interest, because it provides almost total fleshing waste discharge while obtaining qualitatively and economically valuable products. The main target of this scientific paper is investigating the development possibilities for various multicompound systems of biodegradable polymers and studying the effects of these complex products on the structure and chemical and physical characteristics of degraded or contaminated soils (having a poor level of organic matter or submitted to a strong erosion process). The paper presents a new pilot technology for biochemical decay of the tannery protein wastes and use of the resulted products as fertilizers. In the present paper, the agrochemical base of biofertiliser use is investigated, analyzing the principle and dynamics of nutrient elements penetrating soil and plants, their influence on weathered soil rehabilitation/conditioning and on plant growth and development, as well as in agrochemistry of nutritive elements.
