The Different Level of Nitrogen (N), Phosphorus (P) and Potassium (K) on Composting with Activator Media of Cow Dung and Goat Manure on Composting
Background :Organic waste can be used as compost. To accelerate decomposition activators media can be used cow dung and goat manure that can produce high levels of nitrogen, phosphorus and potassium varied. The aim of research is to determine the differences in the levels of nitrogen (N), phosphorus (P) and potassium (K) in the compost activator media cow dung and goat manure in composting.
Methods :The study design is a true experimental design with equivalent control group. The population of all organic waste to sample from organic waste is taken by simple random sampling technique. Media independent variables and the dependent activator levels of N, P and K were collected by laboratory examination. Data were analyzed by ANOVA (Analysis of Variance).
Results :From the results, the mean value of the N content controls 31.48%, 56.76% cow manure media and media goat manure 54.48% with the highest media cow dung, the mean level of 11.43 ppm P media control, media manure 15 , 62 ppm and media goat manure 16.294 ppm with the highest on the junk media goat manure, the mean levels of C waste by media control 13.685 ppm, media cow dung 20.616 and media goat manure 20.839 with the highest junk media goat manure, F (2, 6 ) = 874.698; p <0.05, there are differences in the levels of the end of the P litter significantly between controls, media cow dung and goat manure media, F (2, 6) = 726.093; p <0.05, and there are differences in levels of late K litter significantly between controls, media cow dung and goat manure media, F (2, 6) = 612.000; p <0.05.
Conclusion :From the results of this study concluded that nitrogen levels are highest composting with the media of cow dung. Phosphorous levels are highest in composting with media of goat manure. Potassium levels are highest in composting with goat media. The different media activators will produce high levels of different N, P and K.
