Microbial community in soil with application of various types of exogenous organic matter

Recycling of solid biowaste and manure would reduce the dependence of agriculture on synthetic products. Most of available studies on the effects of exogenous organic matter (EOM) application to soil were focused on nutrients and crop yield, with much less attention to microbiological processes in soil. The aim of this study was to evaluate the effects of various types of manure, sewage sludge and bottom sediment on the biochemical activity and biodiversity of soil and plant yield in the pot experi-ment. The soil was treated with a range EOM types: 6 types of manure (cattle, pig, goat, poultry, rabbit and horse manure; 2 bottom sediments (from urban and rural systems); 2 types of municipal sewage sludge.
