METHOD OF FARM PRODUCE PRESERVATION
The proper keeping of food until they are needed is called food preservation. Some crop Plants will need to store until the next planting season. To make sure that they are good for planting (viable), they must be properly preserved.
IMPORTANCE OF FARM PRODUCE PRESERVATION
