Why apply organic fertilizer when farming? What are the benefits of applying organic fertilizer? What effects does organic fertilizer have? Below, Zhongdi Network gives a brief introduction for netizens' reference.1. Comprehensive nutrients: Organic fertilizer is a complete fertilizer, containing abundant macro- and secondary elements such as carbon, nitrogen, phosphorus, potassium, calcium, magnesium, sulfur and silicon that crops need for growth and development, as well as a certain amount of trace elements such as iron, copper, zinc, manganese, boron and molybdenum.
2. Improving soil: Organic fertilizer contains a large amount of organic matter. Long-term application can increase soil organic matter, improve soil aggregate structure, promote the reproduction of soil microorganisms, and make the soil loose and airy, easy to drain and cultivate.
3. Retaining fertilizer and water: Applying organic fertilizer can enhance the soil's fertilizer retention capacity and buffering power. Humus is an organic colloid; although its particles are small, its surface area is large, and its water absorption capacity is more than 100 times that of inorganic colloids, with an exchange capacity 4 times greater. Long-term application of organic fertilizer can increase organic-inorganic composite colloids, make the soil closely integrated, and enhance the ability to retain water, retain fertilizer and supply fertilizer.
4. Promoting crop growth: In the humus of organic fertilizer, the main component is humic acid, which can promote seed germination, root growth and nutrient absorption. Applying organic fertilizer can also increase the concentration of carbon dioxide, an important raw material for photosynthesis, by several times to several dozen times.
5. Improving fertilizer use efficiency: Combining organic fertilizer with chemical fertilizer can balance slow and quick effects, complement each other's strengths and weaknesses, and promote each other. The acids produced when organic fertilizer decomposes can promote the dissolution of mineral nutrients.
6. Improving the quality of agricultural products: Organic fertilizer is essential food for crops. The nutrients and effects of organic fertilizer cannot be replaced by other fertilizers in many respects, so we should apply more organic fertilizer.
