Poultry manure physicochemical properties Fertilizer from Solid Pyrolysis.

Abstract

In this paper, we consider the possibility of using a solid pyrolysis product of litter poultry manure as a potential fertilizer and soil structure improver for agricultural purposes. he results showed that the granulometric composition of solid pyrolysis products, humidity, and mass fraction of ash and bulk density were studied. The parameters of water extract are studied. The content of heavy metals ions was determined by the method of atomic absorption spectroscopy. By ion chromatography the content of acidic residues in the aqueous extract were determined. The biological oxygen demand (BOD) was investigated by the Iodometric method.
