Organic fertilizer has comprehensive nutrients, long fertilizer effect, wide sources, large potential, low cost, and the role of improving soil, which can not be replaced by inorganic fertilizers. Organic fertilizer plays an important role in farming.

1. Full of nutrients. Organic fertilizer is a complete fertilizer, containing abundant carbon, nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, silicon and other large and medium elements required for crop growth and development and a certain amount of iron, copper, zinc, manganese, boron, molybdenum and other trace elements.

2. Improve the soil. Organic fertilizer contains a lot of organic matter, long-term application can improve soil organic matter, improve soil aggregate structure, promote soil microbial reproduction, make the soil loose, ventilated, easy to drain and cultivate.

3. Keep fertilizer and water. The application of organic fertilizer can enhance the soil's fertilizer retention performance and buffer power. The humus is an organic colloid, although the particles are small, the surface area is large, the water absorption capacity is more than 100 times larger than the inorganic colloid, and the replacement amount is 4 times larger. Long-term application of organic fertilizer can increase the number of organic and non-body compound colloid, soil fusion is close, and enhance the ability of water retention, fertilizer preservation and fertilizer supply.

4. Promote crop growth. In the humus of organic fertilizer, the main component is humic acid, which can promote seed germination, root growth and nutrient absorption. The application of organic fertilizer can also increase the concentration of carbon dioxide, an important raw material for photosynthesis, several times to dozens of times.

5. Increase fertilizer utilization rate. The combination of organic fertilizer and chemical fertilizer can alleviate emergencies, complement short and long, and promote each other. The acid produced during the decomposition of organic fertilizer can promote the dissolution of mineral nutrients.

6. Improve the quality of agricultural products.

The above is all the benefits of organic fertilizer, I hope to help you!
