Characteristics of different organic manures

Abstract

The experiment was undertaken to study the characteristics of different organic manures viz, farm yard manur (FYM), vermicompost (VC), poultry manure (PM) and sheep manure (SM). The analytical results revealed that both poultry manure and vermicompost contained same amount of total organic carbon (22%) but however, C:N ratio of poultry manure was narrow (10) compared to vermicompost (20.54). Maximum water holding capacity was highest in poultry manure (100.52 %) followed sheep manure (99.95 %). The loss on ignition was highest in FYM followed by sheep manure. The poultry manure contained highest concentration of both macro and micronutrients followed by sheep manure, vermicompost and farm yard manure.
