Site selection: When composting, choose a place that is closer to the fat source, leeward and easier to transport. Reactor pile: The shape of the manure pile is preferably rounded, with a height of 1 meter or more to facilitate insulation. After determining the bottom of the compost, first spread a layer of culvert or grass, and stack the mixed farmhouse fertilizers layer by layer. Antifreeze: In order to speed up the fermentation, you can plan a pit in a heap of fat. You can plan two large pounds of fat, pile up weeds in the pit, and then light up the smoke and smoke slowly. Sealing: Cover with a random layer of grass around the fat heap to form a 30-50 cm thick insulation layer, then close the plaster and cover the waste plastic film.
