Daftar Isi:
- The aim of this research was to: 1) evaluate the variability and population of macro flora on different land use types of swamp area at Ogan Ilir Regency in dry, and 2) evaluate the correlation between soil chemistry and physics characters and the macro fauna population. Based on this study, the conclusion that could be extracted was: 1) on the agricultural area, the number of species and population on surface soil was higher than sub soil. On the other hand, in the ex-fired area and secondary forest area, the number of species and population on surface soil was lower than in the sub soil. While the highest soil macro fauna biomass was existed on secondary forest area, 2) the highest of variability index was found in surface as well as in sub soil on the secondary forest area. the middle variability index was found on maize and red paper cultivation area. The lowest variability index was found on rice cultivation area, and 3) the macro fauna variability index in surface soil had a significant correlation only to organic matter content, whereas in the sub soil area, it had a significant correlation to organic mater content, soil pH, and N-total, P-available and soil porosity. The macro fauna biomass had a significant correlation to soil pH, organic matter and N-total.
