Hello, rotten hay can be fermented to make fertilizer. You can use natural composting as fertilizer, but this method can't be completely fermented. After application, the roots and seedlings will be burned, the fermentation time will be longer, and the nutrient components will be greatly lost. Now everyone buys a special fertilizer starter to make fertilizer. There are also many companies selling leavening agents in the market. I suggest you use Gymboree brand fertilizer bulking agent. Gymboree fertilizer leavening agent has been sold for many years, and its products and technology have been upgraded. The operation method is relatively simple and the success rate is guaranteed. Let's briefly talk about the use steps of the product:

Step 1: Mix the starter evenly. Add 5 ~ 10 kg of rice bran or corn and bran to each kg of starter, and sprinkle it into the prepared material after stirring evenly, and the effect is the best.

Step 2: Adjust the carbon-nitrogen ratio. The carbon-nitrogen ratio of fermented fertilizer should be kept at 25 ~ 30: 1, and the pH value should be adjusted to 6 ~ 8 (pH). It is best to add some animal manure to the hay for fermentation.

Step 3: Adjust the moisture of hay. In the process of organic fertilizer fermentation, it is very important whether the water content is appropriate, neither too high nor too low, and it should be kept at 60 ~ 65%. Judgment method: Hold a handful of materials tightly, so that the watermark can be seen between fingers without dripping, and it can be scattered when landing.

Step 4: Stack hay. When making a fermentation pile, it should not be too small or too short. Too small will affect fermentation. Generally, the pile with a height of about 1.5 m, a width of about 2 m and a length of more than 2 ~ 4 m has better fermentation effect.

Step 5: stir evenly and ventilate. Gymboree fertilizer fermentation AIDS are oxygen-consuming microorganisms. During the fermentation process, oxygen supply measures should be increased, and the materials should be stirred evenly and ventilated frequently, otherwise anaerobic fermentation will affect the fermentation effect of the materials.

Step 6: Fermentation is completed. Generally, after 48 hours of chicken manure accumulation, the temperature will rise to 50 ~ 60℃ and reach above 65℃ on the third day. In this high temperature, it overturned once. Generally, there will be high temperature above 65℃ for 2 ~ 3 times in the fermentation process, and the fermentation can be completed after turning over for 2 ~ 3 times, which can be completed in a normal week or so, so that the materials can be completely deodorized, fermented and decomposed, sterilized and insecticidal.
