How to ferment pig manure cattle

The method for ferment pig manure into fertilizer is simple:

Mix pig manure with straw, sawdust, mushroom residue, etc. Appropriate proportion (manure accounts for 80-90%, others account for 65,438+00-20%). 1 ton of material (about 2.5 tons of fresh material) is added with pig manure starter 1 kg and rice bran 5 kg (calculated by 1 kg pig manure starter).

Pay attention to proper oxygen supply and pile turning during fermentation, and control the temperature at 55-65℃. If the temperature is too high, the nutrients will be affected. The water content of fermented materials should be controlled at 60-65%. Too high or too low is not conducive to fermentation, and too little water will also lead to slow fermentation. Too much water will lead to poor ventilation, slow temperature rise and bad smell. Methods to adjust the water content of materials: straw, sawdust, mushroom residue, dry soil powder, etc. If the water content is too high, it can be added. The method to judge whether the water content is appropriate or not: Hold a handful of materials tightly, and when you see a watermark between your fingers, it will disperse when you land.

In the whole fermentation process, the materials can be completely deodorized, fermented, decomposed and sterilized. After 5-7 days, the finished organic fertilizer is fluffy, dark brown, slightly fragrant or earthy, rich in nutrition, safer and more convenient to apply in farmland, and has higher added value as nutrient soil for fruits and vegetables, cash crops, seedlings and flowers.
