During the production process, edible oil processing plants will produce various raw material residues, such as rapeseed cake, bean cake, peanut bran, etc. These are not only high-quality feed, but also high-quality organic fertilizer raw materials. However, in order for cake fertilizer to become usable organic fertilizer, it needs to be fermented. So, how do edible oil processing plants use compost turning machines to ferment cake fertilizer?
First, soak various cake fertilizers with a small amount of water, or chop or smash them, and then adjust the water content to about 60%. If there is too much water, dry it in the sun before fermenting. Pay attention to fermenting solid fertilizers. Do not add too much water, otherwise it will easily stink. Method to judge the water content: stir evenly after adding water, grab a handful with your hand and squeeze it hard. There is water between your fingers but it does not drip. It can automatically disperse when it falls gently on the ground. This is the standard. If conditions permit, you can add organic fertilizer fermentation agent during fermentation, stir it evenly and put it in a place with high temperature and no sunlight, avoid rain and sunlight, for about 2-3 days, when the middle temperature reaches above 50 degrees, use a compost turning machine to turn the compost, turn it every few days until the temperature drops and the fermentation is complete. The fermented cake fertilizer is dark brown, with a slight fragrance or fermentation smell, and can be used as fertilizer.
Although cake fertilizer is a good natural organic fertilizer, the price is relatively high. If you only use cake fertilizer to grow vegetables, it will not have much effect if you use less, and the cost is a bit too high if you use more. If you use cake fertilizer mixed with other organic fertilizers, it can save costs, nourish the land, and play a good effect. In general, the compost turning machine helps to speed up the fermentation of cake fertilizer and promote its even and full fermentation.
