Organic fertilizer coating machine can maintain the nutrients of organic fertilizer to a certain extent, for the following reasons:

Physical isolation effect

1. Reduce nutrient volatilization: The coating machine forms a uniform coating on the surface of organic fertilizer particles. This film can act as a physical barrier, reduce the contact between air and organic fertilizer particles, thereby reducing the volatilization rate of nutrients and maintaining nutrients such as nitrogen in organic fertilizer.

2. Prevent nutrient leaching: When organic fertilizer is applied to the soil, when it encounters precipitation or irrigation, the water-soluble nutrients in it are easily leached with water. Coating can slow down the speed at which water enters the organic fertilizer particles, thereby reducing the leaching loss of nutrients.

Slow-release control effect

1. Adjust the nutrient release rate: The coating machine can use different types of coating materials, which have different permeability and degradation rates. By selecting appropriate coating materials and coating processes, the release rate of nutrients in organic fertilizer can be controlled to match the growth needs of crops.

2. Continuous supply of nutrients: The coated organic fertilizer can continuously release nutrients for a long time and provide a stable supply of nutrients for crops. This is especially important for some crops with a long growth period, which can avoid affecting the growth and development of crops due to excessive one-time fertilization or insufficient nutrient supply.

Protect beneficial microorganisms

1. Maintain the activity of microorganisms: Some organic fertilizers contain beneficial microorganisms, such as nitrogen-fixing bacteria and phosphate-solubilizing bacteria. These microorganisms can play an important role in the soil, such as promoting nutrient conversion and improving soil fertility. The coating can provide certain protection for microorganisms, reduce the impact of external environmental factors on microorganisms, and maintain their activity.

2. Promote microbial reproduction: Some components in the coating material may provide a suitable growth environment for microorganisms and promote the reproduction and growth of microorganisms. This helps to increase the number of beneficial microorganisms in the soil, further improve soil fertility and the effect of organic fertilizers.

In summary, the organic fertilizer coating machine can maintain the nutritional content of organic fertilizers to a certain extent and improve the fertilizer efficiency and utilization value of organic fertilizers through physical isolation, slow release control and protection of beneficial microorganisms.
