Biological indicators are considered soil quality elements, due to their dependence on soil organisms. In order to investigate The effect of compost and vermicompost enriched by chemical fertilizers and manure on soil organic carbon, microbial respiration, and enzymes activity in basil plant's rhizosphere, a field experiment was conducted as a split-plot design with randomized complete blocks a...

The root and flowers of Butea monosperma (Lam.) were extracted with methanol. Extensive chromatographic separation and purification with the organic solvents was done. Four phytochemicals were separated and their structures were established based on various spectroscopic techniques. Isolated crude extract was subjected for antibacterial activity against gram-negative and gram-positive bacteri...

The pyrolysis of fruit trees Pruning waste to be converted to biochar with microbial inoculation is a strategy improving the biological properties in calcareous soils. In order to investigate the biochar effect on some soil biological properties of the soil in the presence of microorganisms, a factorial experiment was carried out in a completely randomized design in the rhizobox under greenhous...
