Abstract
Rapid composting is an essential process for organic manure waste management and the production of nutrient-rich soil amendments or organic fertilizer. This study aimed to investigate the efficacy of T. harzianum in composting by evaluating the time of full decomposition and comparative analysis of the physical qualitative analysis and physiochemical properties. The Institute of Biological Sciences (IBS) small scale rapid composting is used for the experimental set-up. Results revealed that T. harzianum significantly accelerated the decomposition of organic matter mixture substrates compared to the control groups. The process consists of two steps, the use of a compost fungus activator or the T. harzianum as bioinoculants for active decomposer and the composting process itself. In the two substrates, 12 kg of pure buffalo manure and 2:1:1 ratio of manure, rice straw and CRH for organic matter mixture substrates. The combined mixture of 1.14 liners of distilled water with 14.4 grams of T. harzianum bioinoculant was equally applied and sprayed with 190 ml for each compost block in treatment 3 and 4. The compost post analysis comparison. PBM substrates shows significant results in a positively increase amount of N, P, K. The OMM substrates, moisture content and phosphorus are significantly difference. The pH level of all the treatments meets the standard of 5.5 to 8. The presence of T. harzianum in the organic matter mixture compost also led to accelerated decomposition compared to the PBM substrates and the two control treatments. The days of full decomposition achieved in a shorter time period for about 53 days in treatment 4 (OMM with TZ) compared to the control group.
