The use of cow dung as fertilizer in the planting process is to provide the nutrients needed for crop growth. However, when using cow dung in the planting field, it should be noted that cow dung must be decomposed in the organic fertilizer fermentation tank before being used as organic fertilizer. When it is decomposed at high temperature, it will kill the insect eggs and bacterial viruses in the cow dung. In addition, cow dung can be reused after fermentation and decomposition to avoid burning the roots due to heat.
For the production line of cow manure organic fertilizer, it is recommended to adopt aerobic fermentation treatment. It can be fermented with fermenting agent, which is better for crops. Mix cow manure with straw, sawdust, mushroom residue, etc. in an appropriate proportion (dung accounts for 80-90%, other accounts for 10-20%). 1 ton of material (about 2.5 tons of fresh material) plus 1 kg of fertilizer starter, diluted by 1 kg of fertilizer starter plus 5 kg of rice bran (or bran, corn flour and other substitutes), and then evenly scattered into the material pile. Pay attention to proper oxygen supply and pile turnover during fermentation, and control
