The estimation of the influence of fertilizer compounds compositions on the intensity of mineralization processes during composting

One of perspective ways to utilize sawdust, bark, bird droppings is to use it as a basic component for organic compost production. The purpose of the research was to study the effect of bird droppings additives during composting of sawdust and bark on the intensity of mineralization processes. The tasks were studying the action of additives of a bird's dung in wood waste on the speed of decomposition of organic substance; optimization of structure of fertilizer compounds. The objects of the study were sawdust, bark, bird droppings and mixtures based on them. In a laboratory experiment on bird droppings additions on waste bark on mineralization rate and total C-CO2 losses from compositions were studied throughout 12 months of composting using the absorption method modified bySharkov. As a result of researches it was established that wood waste and a bird's dung punched separately reduce intensity of process of a mineralization of organic substance, and their combined use enhances mineralization processes...
