Ecological evaluation of influence of a vermiculture on the content of heavy metals and their mobility in the vermicomposting on the base of buckwheat pod, a defekat, slag and zeolites

All production activity of the person is connected with inevitability of different formation of waste which comes to the environment. In order to avoid the unnecessary, and at times and irreparable injury caused to the environment, such influence has to be planned carefully. At the same time it is necessary to combine satisfaction of persons needs at the expense of the nature with active protection of the environment against consequences of human activity. As a rule, these purposes don't exclude each other though in certain cases it is necessary to accept the compromise verdict. Search of global ways of reduction of negative impact of toxic substances on agroecosystems requires the increasing attention to the solution of problems of utilization, processing of organic waste. At the same time the vermicomposting method - process of processing of organic waste with use of earthworms, development of industrial technology of cultivation of earthworms and production of a bio humus more and more is widely used. Numerous researches show that application of this technology allows to improve physical and chemical characteristics of initial raw materials, does possible application in agricultural ecosystems containing the organic waste, in other words: the granulated humus fertilizers as vermiculture waste product, facilitates transportation and storage. Manure of various animals, peat, sawdust, straw, cardboard, paper, leaves of trees, tops of vegetable, waste of processing of food, waste of the fishing and meat industry, organic city waste, etc. can be a nutritious substratum for worms. The possibility of a vermiculture use for a composting of solid waste of the cereals industry (pod of a buckwheat and pod of peas), cattle and pork manure, a deposit of Oryol sewage, eliminations of salt aluminum slag, waste of the sugar plant (a press, excrement), natural zeolites in various ratios were studied in laboratory experiments.
