Eyahiation of Manurial Value of Biogas spent Slurry Composted with Dry Mango Leaves, Wheat Straw and Rock Phosphate on wheat Crop

Abstract

An attempt has been made to handle efficiently the liquid biogas slurry and to improve its manurial value by absorbing the slurry in dry mango leaves or wheat straw, enriching it with Mussoorie rock phosphate and then composting for 20 and 40 days. The manures so prepared were evaluated by judging their influence on wheat yields, nutrient uptake by plant and post-harvest fertility status of the soil. Results show that 40-days. The composted Mussoorie rock phosphate-enriched biogas slurry absorbed in dry mango leaves was the best as manure for wheat.
