How to deal with manure from cattle farm?
1. First, the cow dung should be dried to keep its moisture content below 85%, and then add straw powder, the ratio of cattle and straw is 7:3, so that the carbon ratio of raw materials (cow dung) and auxiliary materials (straw straw) can be controlled at 23~28, the water content is controlled at 52%~68%. Finally, the organic fertilizer fermentation decomposing agent is added.
2. After the raw materials, auxiliary materials and bacterial agents are mixed, they can be stacked and fermented. The requirement of stacking is to stack the mixture on the fermentation field into a bottom width of 1.8 meters to 3 meters, a top width of 0.8 meters to 1 meter, and a height of 1 meter. The trapezoidal stack of meters to 1.5 meters, the interval between the stacks is 0.5 meters. After the stacks are stacked, the temperature will rise to above 60 degrees within 24 to 48 hours, and after the temperature is maintained for 48 hours, it can start turning the stack.
3.When turning the materials, it must be even and thorough, and the low-level materials should be turned into the middle and upper part of the heap as much as possible, so as to be fully decomposed. After the first turning, the heap should be turned once a week. When the temperature exceeds 70 degrees, the pile should be turned over immediately, otherwise beneficial microorganisms and fermenting bacteria will be killed in large quantities, which is not conducive to fermentation and decomposing.
