From the statistics it was seen that India is expected to produce 260 million layers (77,700 million eggs) and 3500 million broilers (5.9 million tonnes) in the year 2010. Poultry development in the recent past has shown very fast development and at present in A.P. the total population of poultry is 193 millions and from these birds the litter is estimated at 17.70 lakh tons per year. This tremendous increase of poultry industry results in substantial amounts of poultry litter, which can efficiently use in solving the present agronomic problems thus leading to sustainable agriculture. The application of poultry litter on land has been a long used disposal method that benefits soil and plant. Composted poultry litter is being applied on agricultural fields as an amendment to provide nutrients and also enhance the organic matter content and improve the physico-chemical properties of the cultivated soils. In the present study, quantitative changes in physical, chemical and microbial properties of composted poultry litter were studied. In order to understand the composting process and evaluate the suitability of composted poultry litter as soil amendments to Lycopersicum esculentum plant, Lycopersicum sps was planted and monitored for growth performance and yield. The effect of land application of composted poultry litter on the soil organic matter content and other properties as the soil quality indices were being evaluated in this case study.
