Abstract

The microbial biomass carbon of soil is being increasingly recognized as a sensitive indicator of soil quality. Its knowledge is fundamental for sustainable environmental management. This study aimed to determine the impact of organic and chemical fertilizers and their combination on soil microbial biomass carbon, maize yield and the relationship between soil microbial biomass carbon, maize yield and some chemicals properties of soil using the chlorofrom lumigation extraction method. For this purpose, a total of 8 treatments with triplication were conducted, such as control, 100% chicken manure, 100% Gliricidia sp. leaf, 100% chemical fertilizers (CF), 50% chicken manure + 50% CF, 50% Gliricidia sp. leaf + 50% CF, 75% chicken manure + 25% CF 50% Gliricidia sp. leaf + 50% CF. One-Way ANOVA showed a significant difference in biomass C-mic and maize yield between treatments. Organic and chemical fertilizers treatment signitificant higher in biomass C-mic and maize yield cumpare with control. The treatments of chicken manure were shown to be signilicantly higher than the others and better in C-mic value compare Gliricidia sp. leaf'. The biomass C-mic and maize yield correlated to the chemical propcrtics of the soil, such as organic C, total N, and pH. Present study clearly shows that chicken manure is better amended ultisols soils.
