Bag storage is one of the most common storage in many countries. Grains after threshing usually stored in 50-100 kg capacity jute bags. Sometimes woven plastic bags of 25-30 kg are also used.

Depending on the size of storage, stack is then formed. If the bags are stored in a multi-purpose farm shed or at farmer’s house, care should be taken that rats could not damage the bags. For this, a raised platform equipped with rat guard structures may be used.

Following points should consider before using bag storage.

  • The stack of Jute bags should not form higher than 4m. In case of plastic bags stack height should limit up to 3 m as these bags are more slippery.
  • Bags should be stacked under roof, shed or under waterproof tarpaulins.
  • Approximate gap of 1m should left in between and around the stack. A clearance of 1.5 m should keep between top of stack and roof.  
  • To avoid any possibility of moisture absorption by bags, Bags should always be stacked above ground level or on wooden pallets.
  • Bags should be stacked in such a way that fumigation operation can perform easily.
  • There should be easy sweeping the floors, easy inspection for rodents and insect infestation and easy counting of the bags.
  • Some farmers store the bags in granaries separately constructed for storage. Such entire structure should be moisture proof.
  • Large size doors and ventilators should be provided to the structure.
  • Ventilators fitted with wire netting and shutters should be provided to the bagged storage structure.
