Silage is fodder that has been preserved through a fermentation process. It involves harvesting crops like corn, sorghum or other grasses and storing them in silos or wrapping them in plastic to prevent air exposure and allow for fermentation. The total cost of a silage project is approximately 28.08 lakh Indian rupees, including land, machinery like a square auto bailer machine and silage tube press, and equipment like a vacuum pump. The promoter has 1000 square feet of land and the processing unit has a 2 tonnes per hour capacity.
