When the cattle manure drying machine, with a hydraulic composting machine, was sent to our client’s farm, we assisted the client with the machine installment through video calls. In addition, we expatiated the details of making cow dung compost, including the processing of fresh manure, the ratio of cow dung and other material and the times of turning compost. With our guide, the client made a new cow dung compost whose temperature rose quickly in the first week. We accentuated that he needed to turn it when the temperature was above 140 ℉. After 3 weeks, the client sent us a picture of his composted cattle manure. The manure, or organic fertilizer powder as it should be called, was a dark-drown color, without too much water. If the client wants, he can use it to make granular fertilizer!
