Abstract

In-situ Agro-waste management become a challenge now a days. One of the best managements is to decompose the agro-waste by inoculation of microbes. In this experiment the three agro-wastes were decomposed by taking three isolated cellulose degrading bacterial strain. The experimental was carried out in Department of Soil Science and Agricultural Chemistry, College of Agriculture, Bhubaneswar, India. The different size fractions of matured compost were determined by sieving manually with 4 mm, 2 mm, 1 mm and 0.5 mm sieve and Cation exchange capacity was determined by ammonium acetate saturation method. The inoculation of CBC9, CBD4 and CBG2 to maize stover resulted into 92, 93 and 95% of <4mm, 83, 86 and 87% <2mm, 32, 35 and 36% <1mm and 5, 7 and 8% <0.5mm size compost. The smallest (<0.5 mm) size fraction compost was higher in vegetable waste followed by maize stover and paddy straw. The cation exchange capacity of all the size fractions were highest in CBG2 inoculated compost followed by CBD4, CBC9 and lowest was in uninoculated compost. Likewise, among the substrates highest cation exchange capacity was estimated in vegetable wastes followed by maize stover and paddy straw. Among all compost, lowest cation exchange capacity (45 cmol (p)+ kg-1) was estimated in <4mm compost where paddy straw was not inoculated with any strains and highest (277 cmol (p)+ kg-1) was estimated in the <0.5 mm size compost produced from vegetable wastes inoculated with CBG2 strain.

Conclusion

Among three substrates, vegetable waste is better for production of compost with higher per cent of smaller fractions and higher cation exchange capacity. Among the strains CBG2 was most effective in production of compost with higher percent of smaller fraction and higher cation exchange capacity.
