Study on The Use of AINA Microbial Inoculant for Aerobic Composting of Chicken Manure

Abstract

Composting is a quick, effective, and environmentally friendly solution for treating chicken manure. Adding microorganism inoculants to composting materials makes the composting process more effective and improves product quality. This study was carried out to investigate the effect of AINA inoculant on composting of chicken manure. Four treatments (NT1, NT2, NT3, and NT4) were supplemented with AINA microbial inoculant at rates of 0 %, 0.5 %, 1 %, and 1.5 % (v/w). The results showed that the highest temperatures of NT1, NT2, NT3, and NT4 treatments were 46.7 °C, 48.3 °C, 45.5 °C, and 53.7 °C. The final composts' EC, pH, and moisture indicators had 2 - 4 mS/cm, 7.2 – 8.8, and moisture from 53 % - 56 %. The mesophilic and thermophilic bacteria densities were higher than 109 CFU/g and 105 CFU/g. The GI index of final composts in 4 treatments was 83.93, 123.64, 120.75, and 88.78 showing that the compost was mature and nontoxic to plants. The main root length and stem length indicators of NT2 and NT3 were 48.47 mm, 47.33 mm, 60.60 mm, and 56.27 mm being statistically significantly higher than with the remaining treatments (p = 0,05).
