COMPLEX AGROECOLOGICAL ESTIMATION OF APPLICATION OF UNIQUE FERTILIZERS
Abstract
The article shows the results on soil recycling of municipal waste. The authors declare that application of unique fertilizers dosed economically efficient does not influence much the qualities of grey forest soil plough-layer. Single application of wastewater sludge dosed as 12t/ha increases humus concentration, cation exchange capacity and environmental pH becomes weakly alkaline. The paper finds out that efficient application of wastewater sludge doesn’t make effect on element burden and doesn’t break ecological balance. The authors conduct research on soil recycling of municipal waste with lime, which causes alkalinization of the soil in order to reduce migration mobility of heavy metals, which restrict their application. The research has shown that all parameters of total heavy metals were lower than admissible concentration unit in the years of fertilizing and in the following years. Soil pollution was minimal according to all criteria. The authors estimated bioenergetics efficiency of single application of wastewater sludge dosed as 12 t/ha when growing potato. Single application of wastewater sludge dosed as 12 t/ha demonstrated that wastewater sludge is high energy fertilizer. Stacking energy in extra yield at single application of wastewater sludge increased energy coefficient for the 3d year. This contributes to soil recycling of wastewater sludge as a fertilizer in case of biogeo-chemical monitoring of heavy metals concentration in the soil for growing environmentally sound production.
