Cow Manure Compost Fermentation
There are two main methods for aerobic composting of cow dung: (1) Stack type composting process: the materials with proper moisture adjustment are layered into stacks according to the height and width, and the stacks are arranged in parallel on the open or indoor flat composting yard, and the efficient professional turning is adopted. The organic manure composting machine straddles the pile for continuous turning operations. The cross-sectional shape of the pile is triangular or trapezoidal: width 1.5-2.5m, height 0.8-1.4m, length 50-150m (depending on the shape and size of the composting site). The characteristics of the process: the mechanical turning operation is highly mobile, and the use of strip stacks is conducive to the loss of water in the later stage of composting; it has low requirements for civil engineering and does not need supporting fermentation tanks. It can be composted outdoors, saving construction investment; the area of composting site needs to be rel...
