Bioenrichment of poultry manure by association of a fungus Trichoderma harzianum 128

Abstract

The purpose. To study features of growth of association of fungi Trichoderma harzianum 128 at enrichment of compost of organic matter on the basis of poultry manure and to evaluate perspectives of bio enrichment of compost. Methods. Laboratory (for simulation of process of bio enrichment); industrial (approbation of technique of enrichment); field (determination of efficiency of compost at growing potato); statistical. Results. In conditions of model experiments the optimum terms of introduction in compost substrate of agronomically valuable microorganisms depending on their predominant functions are fixed. Application of T. harzianum 128 for 2-nd month of enrichment of compost promotes prompt growth of strange micromycets. Efficiency of technique is shown under production conditions. The gained biocompost is characterized by heightened total carbon and nitrogen, positively influences productivity of potato and product quality. Conclusions. Enrichment of compost of substrate on the basis of poultry manure at add-on of association of T. harzianum 128 ensures intensification of mineralization processes and accumulation of agronomically valuable microorganisms — active destructors of organic matter and producers of physiologically active joints. The gained biocompost is perspective for use in farming industry.
