First, the material ratio. Mix chicken manure, pig manure, mushroom residue, straw, dry soil powder, etc. in an appropriate ratio. About 3-4 tons of fresh manure plus 1 kg of organic fertilizer starter, the starter is diluted and evenly sprinkled into the manure pile and mixed evenly.
Second, build a pile of materials. Making the pile too small will affect the fermentation. The height of the pile should be 1.5 to 2 meters, the width is 2 to 3 meters, and the length is more than 3 meters, so that the fermentation effect is better.
Third, moisture requirements. The moisture of the fermentation material should be controlled at about 65%. Too high or too low is not conducive to fermentation, less water and slow fermentation; too much water, poor ventilation, slow heating, and produce odor. If the moisture is too high, add straw, mushroom residue, dry soil powder, etc. Whether the moisture is suitable, you can hold a handful of the material tightly, see the watermark on your fingers, but do not drip, and it will disperse when it hits the ground.
Fourth, turn over and ventilate. During the fermentation process, proper oxygen supply and dumping are required (the temperature rises to 75°C or above, and the stack must be tipped several times). The temperature of the stack is controlled at about 65°C. Excessive temperature has an impact on nutrients.
Fifth, fermentation is complete. Generally, the fermentation can be completed within 5-7 days, the material is dark brown, and the temperature drops to room temperature, indicating that the fermentation is complete.
In the fermentation process, the tool we generally use is a compost windrow turner. This organic fertilizer machine will greatly save time, improve efficiency, and create more benefits.
