Aml M. Abd EL-Satar; M. E. EL-Haddad; Mona S. Zayed and G.A.M. EL-Sayed ( 2014). Effects of some additives on temperature degree and some biological parameters during composting of rice straw. Agric. Dev. Res., Fac. Agric, Ain Shams Univ., Cairo, Egypt, March, 2014
Abstract: Ten compost treatments were prepared by mixing rice straw with some different addi¬tives. Treatments were arranged in piles ac¬cording to the component of each pile. Initial temperature in all treatments at zero time was 21°C. During the following days considerable variations in temperature were observed in different treatments. The 10 treatments exhib¬ited two groups according to temperature's demeanor. The first group comprises the treatments 1, 2, 3, 4, 5 and 6 which were pre¬pared without addition of cattle dung. The temperature of the mesophilic initial phase of composting process were ranged approxi¬mately from 21 to 45 °C and takes from 9 to 15 days. In the thermophilic phase the tem¬peratures were increased gradually to reach a maximum temperature ranged between 50 and 62°C. The second group comprises the treatments 7, 8, 9 and 10 which were pre¬pared by addition of cattle dung. The temper¬ature of initial mesophilic phase ware ranged from 21 to36°C and takes three days. The thermophilic phase w-?s continued from 35-40 days and the highest temperature degree was reached to 65-67°C. Variations in temperature during composting process lead to succes¬sion of different microbial communities. Dur¬ing the initial phase of composting process the counts of mesophilic microorganisms were increased. As a result of increasing temperature the counts of mesophilic organ¬isms were reduced and the counts of thermo¬philic organisms were increased. While up to the end of compost process the temperature was reduced with resultant reduction in the counts of thermophilic microorganisms and dominating the mesophilic microorganisms in the process. The total and fecal coliform as well as other pathogenic bacteria {Salmonella and Shigella) were not detected in the fin¬ished products
