He use of composting for the treatment of swine manure is an alternative that has been studied, based on this experiment was to compare the use of powdered coconut husk, sawdust and pie sugar cane filter as substrates for composting pig slurry in the coastal region of the state of Sergipe . The temperature of the compound and the environment, the dry matter, moisture and chemical analysis ( nitrogen ), organic C and C / N ratio were evaluated 6 combinations and 5 replicates were tested 100 % sawdust SR; 100% PC shell powder coconut , 100 % pie cane filter - TCA sugar , 50 % sawdust and 50 % coconut shell powder SRPC and 50 % filter cake cane of sugar and 50% coconut shell powder TCAPC and 50 % sawdust and 50 % pie of cane sugar SRTCA filter with five replicates each . Analyses of variance were performed using completely randomized design (CRD) and multiple comparison of means using the SNK test at 5 % probability. SISVAR the statistical software version 5.3 ( 1999 to 2010 ) was used . During the experiment, the temperature of the compound reached was 24.3 ° C, the maximum temperature has reached the compound was 46.62 ° C. The powder of coconut shell and sawdust are substrates that can be used in the composting of liquid swine manure with process efficiency. The pie sugar cane is not indicated in the proportions used for introducing anaerobic box during the composting process. You can be a shortening of composting using coconut coir and sawdust for 90 days.
