PENGARUH Trichoderma Sp. DAN MOLASE TERHADAP SIFAT BIOLOGI TANAH DI SEKITAR LUBANG RESAPAN BIOPORI PADA LATOSOL DARMAGA

Abstract

Organic waste addition into the biopore infiltration hole could improve soil biological. The decomposition organic waste in the biopore infiltration hole could be accelerated by adding activator Trichoderma sp. and molasses. This research aimed at finding out the effect of giving Trichoderma sp. and molasses in soil biological properties including population and diversity of soil fauna, microbes and fungi population at arround the biopore infiltration hole. Design model that used was randomized block design (RBD) with Least Significant Difference (LSD) test on the level of trust 5%. The treatment of this research were, P0: without organic waste (SO) + molasses (M) + Trichoderma sp. (T), P1: addition of SO, P2: addition of SO + M, P3: addition of SO + T, and P4: addition of SO + M + T. The result of this research showed that the addition of Trichoderma sp. (SO+T) and molasses (SO + M) in biopore infiltration hole could improve the soil biological properties. It was indicated by the high of soil microbes population 1,59 x 106 CFU (Colony Forming Unit)/g ADW (Absolute Dry Weight) and significantly higher compared to the P0. Both of the treatments also had the highest population of soil fauna than other treatments, that were 6071 individual m-2 (SO + T) and 1908 individual m-2 (SO + M), and had high population of soil fungi, that were 1,26 x 104 CFU g-1 ADW soil (SO + T) and 1,42 x 104 CFU g-1 ADW soil (SO + M), nevertheless they all did not have significantly effect in increasing the diversity of soil fauna.
