Manure and straw can be prepared using an organic fertilizer turner through composting technology. The following are the specific preparation methods:
Preparation of raw materials: Mix manure and straw in a certain proportion, usually with a ratio of 3:1 or 4:1.
Adjust moisture: Add an appropriate amount of water to the mixture to maintain its moisture content between 40% and 60%.
Adjusting the carbon to nitrogen ratio: By adding other organic materials or chemicals, the carbon to nitrogen ratio of the mixture is adjusted to an appropriate range to facilitate the growth and fermentation of microorganisms.
Composting: Stacking the mixture in a fermentation tank or tower for natural fermentation. During the fermentation process, microorganisms decompose organic matter into stable humus and release heat.
Flipping: During the fermentation process, it is necessary to use an organic fertilizer flipping machine to regularly flip the pile to promote the decomposition of organic matter and the formation of humus.
Drying: After fermentation is completed, remove the humus, air dry it, and then use an organic fertilizer crusher to crush it into powder or granules.
Packaging: Pack the dried organic fertilizer for sale or use.
In the process of preparing organic fertilizers from manure, straw, etc., the following points need to be noted:
Selection and treatment of raw materials: Fresh and harmless feces and straw are selected, and pre-treatment is carried out, such as removing impurities, crushing, etc.
Adjusting moisture and carbon nitrogen ratio: Based on the properties of the raw materials and local natural conditions, adjust the moisture and carbon nitrogen ratio of the mixture appropriately to facilitate the smooth progress of the fermentation process.
Control temperature and oxygen: During the fermentation process, it is important to control the temperature and oxygen content to avoid the growth and reproduction of harmful microorganisms.
Flipping and drying: During the fermentation process, regular flipping is necessary to promote the decomposition of organic matter and the formation of humus. After fermentation, the humus should be taken out and dried, and then crushed into powder or granules.
Packaging and storage: The packaged organic fertilizer should be stored in a dry and ventilated place to avoid problems such as moisture and mold.
