How does straw make organic fertilizer

After the autumn harvest is completed, farmers' friends will again face the problem of handling straw on the ground. Improper handling may affect farming. So, how to handle the straw better? Below, I will introduce the method of straw stacking to help you solve the problem of straw reuse.

Straw dumpling is a process that uses a series of microorganisms to mineralize and humify organic matter such as crop straw. Through composting, the carbon-nitrogen ratio of organic materials can be narrowed, nutrients in organic materials can be released, and the spread of germs, eggs, and weed seeds in composting materials can be reduced. Therefore, the compost maturation process is not only a process of decomposition and resynthesis of organic matter, but also a process of harmless treatment.

Production Method:

1. Select the convenient place for water from the corner of the field, dig it down manually and make the field barn. The field barn is required to be as flat as the bank (capable of retaining water). Rice straw is generally piled up per acre (barley, wheat, two acres piled up), and the amount of straw is about 500 kg, covering an area of ​​6 to 7 square meters.

2. Straws are stacked in layers, each with a height of 40 cm. Pour sufficient water (more preferably with biogas slurry), so that the moisture content of the straw is 60% to 70%, and sprinkle the fungicide; each stack can be stacked with 4 to 5 layers. It is about one person tall and has a barrel-shaped pile. It requires 12.5 kg of bactericide. The top of the pile is concave to facilitate rainwater collection. After the straw is piled up, it is covered with a film (holes are punched), moisturized and insulated, and can be watered from the top of the pile if it is too dry.

3. Generally, the fermentation is started in 3 to 5 days. After 1 month, the pile enters the high-temperature fermentation period. Generally, the pile can be basically rotted in 2 to 3 months (turn over once when the pile enters high temperature, and the outer straw turns over. Into the middle and make up the water, so that the straw fermented and evenly matured), when the next crop is planted, the fully decomposed straw can be returned to the field as an organic fertilizer, and the amount of chemical fertilizer can be reduced.
