Abstract: Experiments have been conducted to determine the augmentation of nutritional values (organic carbon, nitrogen, potassium and phosphorous) of bio-manure. The main substrates have been taken as wheat husk; paddy straw; dairy waste; poultry waste; municipal solid waste and kitchen waste. The substrates have been digested under thermophilic conditions (55 °C). The results show an enhancement in nutritional values in bio-manure where poultry waste has been found to be the best amongst the mentioned substrates. The increase in temperature results in lower retention time and thus reduces the loss of nutrients. The experimental results also show that the intermixing of crop residues with animal waste reduces the quality of bio-manure.
