Use of microplot technique to evaluate the effect of herbicide and organic fertilizer on dehydrogenase activity in lowland rice soil

摘要

Assessment of soil microbial activity is necessary to understand the nutrient fluxes in a given ecosystem. Soil dehydrogenase activity is one of the measures of microbial activity of a large part of the microbial community in the soil (Alef 1995). Inthis study, we used a microplot technique to evaluate the effect of herbicide and organic fertilizer application on soil dehydrogenase activity based on the microbial electron transport system (ETS) activity assay.
