Studies on Aerobic Compost from the Solid Waste Generated in Coimbatore City, Tamilnadu, India

摘要

Waste is an unavoidable secondary product of human activities. Economic development, urbanization and improving living standards in cities, have led to an increase in the quantity and complexity of generated waste. The generated solid waste from Coimbatore city was sorted in to organic waste and various types of aerobic compost such as Rapid compost, Windrow compost, Pit method of compost and Vermicompost were prepared by adding raw materials of different composition. Their physical and chemical characteristics, macro and micronutrient content were evaluated in the field and laboratory. This paper highlights the comparative study between the various types of aerobic composts prepared. pH, electrical conductivity, temperature, total organic carbon (TOC), total nitrogen, phosphorus, potassium and C/N ratio were estimated, and their impact on soil is elaborately discussed in the paper.
