The establishment of a small organic fertilizer production line needs to consider the following conditions:

1. Capital investment: According to the degree of automation and equipment configuration, the investment cost of small organic fertilizer production line is also different. The equipment investment of powder organic fertilizer production line is about 80,000-150,000 yuan, while the equipment investment of granular organic fertilizer production line is 150,000-450,000 yuan.

2. Administrative procedures: It is necessary to conduct feasibility study and demonstration, and submit the project to the local industry and information bureau. At the same time, it is necessary to conduct environmental pollution assessment and apply for industrial and commercial business licenses.

3. Factory planning and construction: With the assistance of the manufacturer, reasonable construction, reasonable placement of relevant equipment should be carried out with the permission of the local land planning department, and wait for the acceptance of the provincial and municipal agricultural department to prepare for the relevant production registration procedures.

4. Equipment procurement: We need to buy a series of organic fertilizer equipment including organic fertilizer granulator, fermentation and throwing machine, crusher, screening machine, packaging machine, etc.

5. Raw material supply: Organic fertilizer production raw materials can be divided into four types according to their characteristics: livestock manure, processing by-products, crop straw and other agricultural waste. A stable supply of raw materials needs to be ensured.

6. Technology and process: master the production technology of organic fertilizer, including fermentation technology, crushing technology, granulation technology, etc., and the corresponding process flow.

7. Market demand: Investigate the market demand and determine the scale and output of the production line according to the market demand.

By meeting the above conditions, a small organic fertilizer production line can be established to realize the recycling of resources, while responding to the national policy requirements for green agricultural development.
