Abstract

Farm yard manure has a great diversity characterized for storage and application. Moisture content, bulkdensity, dry matter content, angle of repose and angle of friction are the major characteristics which arerelated to the performance of manure spreader. A study was carried out to determine different frictional aswell as physical attributes of farm yard manure at laboratory of MCAT at Maya Group of colleges, Dehradun.The Physical attributes of farm yard manure were determined at different depth of manure pit. The size ofpit was calculated as 300 cm × 90 cm × 75 cm. The different depths were taken as 0-18, 18-36, 36-54, 54-72,72-90 cm respectively. The moisture content was obtained 27.96, 35.47, 38.46, 45.05 and 46.94 % at differentdepths and bulk density was observed as 1.66, 1.72, 1.80, 1.80 and 1.89 kg/m3 respectively. The dry mattercontent measured for farm yard manure was 72.04, 64.54, 61.54, 54.95 and 53.11 % at different depth ofmanure pit. The angle of repose was found to be 35.062°, 39.193°, 39.869°, 47.478° and 53.737° at differentdepths of manure pit.
