Study on Attributes of Farm Yard Manure for Paddle Operated Mechanical Applicator

Farm yard manure has a great diversity characterized for storage and application. Moisture content, bulk density, dry matter content, angle of repose and angle of friction are the major characteristics which are related to the performance of manure spreader. A study was carried out to determine different frictional as well 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 of pit 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 different depths and bulk density was observed as 1.66, 1.72, 1.80, 1.80 and 1.89 kg/m3 respectively. The dry matter content measured for farm yard manure was 72.04, 64.54, 61.54, 54.95 and 53.11 % at different depth of manure pit. The angle of repose was found to be 35.062°, 39.193°, 39.869°, 47.478° and 53.737° at different depths of manure pit.
