Abstract
Utilizing cow manure for composting at the same time addressing environmental issues can be a feasible alternative for cow raisers. The study aimed to determine the effects of adding a rapid odor erasing and composting microbes (OECM) at different inclusion rates of: 350 grams per 110 kg raw material (50 kg cow manure + 60 kg fly ash) T2: 400 grams per 110 kg raw material (50 kg cow manure + 60 kg fly ash) T3 and 450 grams per 110 kg or raw material (50 kg cow manure + 60 kg fly ash) T4 on physical properties, temperature, pH, germination rate and percentage compost recovery. the control T1 was 110 kg raw material with no OECM. A Randomized Complete Block Design (RCBD) was used consisting of 4 treatments with each treatment replicated thrice. Tukey HSD was used to further analyze significant differences.
Results showed that the odor of treated compost was no longer evident on day 13 for T2, T3 and T4. The texture from course to fine was observed in day 13 of T2, T3 and T4, while the color from black to brown was demonstrated on day 13 of T2, T3 and T4. the temperature (p,0.01, pH (p.<0.01), compost recovery (p.<0.01), and germination rate (p.<0.01) were significantly different over the control. Therefore, the OECM at 350 grams, 400 grams, and 450 grams per 110 kg raw material is an indispensable additive for cow-based manure as its significantly improved the varying compost quality parameters.
