Rock phosphate enriched post-methanation bio-sludge from kitchen waste based biogas plant as P source for mungbean and its effect on rhizosphere phosphatase activity

► Development of phosphatic bio-fertilizer using post-methanation bio-sludge from kitchen waste based biogas plant, low-grade rock phosphate and phosphate solubilizing fungi. ► Evaluation of agronomic efficiency of these biofertiliers under greenhouse condition using 32P radiotracer technique. ► Evaluation of the effect of these biofertilizers on soil biological properties including rhizosphere phosphatase activity and PSM population.
