Unlabelled: Changing land use systems impact on local edaphic factors and microbial abundance and diversity, however, the information on it in central Myanmar's soils is still lacking. Therefore, soils with four different land uses were analyzed; WAP (soil from perennial tree orchard), PNON (soil from crop rotation of peanut and onion), SESA (soil from mono-crop of sesame) and CHON (soil from mono-crop of onion for 3 years consecutively). Soil organic carbon (SOC), total nitrogen (TN), dissolved organic carbon (DOC), ammonium nitrogen (NH -N) and pH showed the highest in PNON soil, which suggested crop rotation with high fertilizer input and irrigation had positive effect on the edaphic factors of soil.
View Article and Find Full Text PDFIntroduction: , a nitrogen-fixing bacterium, was isolated from rhizospheric soil in central Myanmar.
Methods & Materials: The nitrogen-fixing activity of this bacterium was detected by plate screening method using glucose nitrogen free mineral medium and ammonium test-kit Cellulolytic activity was screened by plat assay and detected by Dinitrosalicyclic acid method (DNS).
Results & Discussion: The isolated grew in media containing 3-12% of NaCl, although the growth became poor when NaCl concentrations increased.
