Soil quality (SQ) assessment considering surface and profile soils holds great significance in sustainable soil health management. We assessed the effect of land-use systems (agriculture, forest and plantation) on SQ using three SQ indices (SQI) models namely additive (SQIa), weighted additive (SQIw) and nemoro (SQIn) from total (TDS) and minimum (...

The phosphorus (P) content in soil is about 0.05% (w/w) but only 0.1% of the total phosphorus is available to plant because of poor solubility and its fixation in every type of soil. Phosphorus solubilizing microorganisms (PSMs) through their various mechanisms of solubilization and mineralization are able to convert the unavailable form into bioav...
