- Abstract
This study aimed to compare the use of sawdust and coir dust as substrates for composting of pig slurry, aiming to give a destination to this waste produces a compound that can be used as organic fertilizer. We used a factorial experimental design with two treatments (sawdust substrate - TSE and coconut coir substrate - TCO) and four replications. We recorded the maximum and minimum temperatures of the compound daily and collected samples for chemical analysis of moisture, dry matter, carbon, nitrogen as well as the calculation of the C / N. During the experiment, the temperatures recorded varied widely among treatments with a minimum of 25 ° C and maximum 37 ° C. The humidity was very high TCO in treatment (70%) is considered unsatisfactory to the composting process. In treating TSE this value was 60% and the values of organic carbon and total nitrogen reached a satisfactory performance for composting as compared with treatment TCO. The C / N ratio reached acceptable levels between the two treatments (TCO and TSE) despite the differences in the levels of C and N in the two substrates.
