1. Improve soil fertility
95% in the soil trace element exists in the form of insoluble state, cannot be absorbed by the plants use, contains large amounts of organic acids and microorganism metabolites substances, these substances like adding hot water in the ice, can quickly trace elements such as calcium, magnesium, sulfur, copper, zinc, iron, boron, molybdenum and other plant essential mineral elements dissolved, become nutrients can be absorbed by the plant directly use, greatly increased the ability of soil.
Organic matter in organic fertilizers increases the content of organic matter in the soil, which reduces the degree of soil adhesion, and thus can give play to good fertility coordination and supply ability.
2. Improve soil quality and promote soil microbial reproduction
Organic fertilizers can make the microorganisms in the soil multiply in large quantities. These beneficial microorganisms can decompose the organic matter in the soil, increase the aggregate structure of the soil, and improve the soil composition.
The beneficial microorganisms in organic fertilizers can inhibit the reproduction of harmful bacteria, so that fewer pesticides can be applied. If applied continuously for many years, they can effectively inhibit soil pests.
Meanwhile, there are various active enzymes secreted by animal digestive tract and enzymes produced by microorganism in organic fertilizers. When these substances were applied to the soil, the enzyme activity of the soil was greatly enhanced. Long-term use of organic fertilizer can improve the quality of soil. If we fundamentally improve the quality of soil, we will not be afraid of failing to produce good fruit.
3. Provide comprehensive nutrition for crops and protect crop roots
Organic fertilizers contain large amounts of nutrients, micronutrients, sugars and fats that plants need. CO2 released by decomposition of organic fertilizer can be used as material for photosynthesis.
Organic fertilizer also contains nitrogen, phosphorus, potassium 5% three elements, organic matter 45%, can provide comprehensive nutrition for crops.
At the same time, the decomposition of organic fertilizer in the soil, can form all kinds of humic acid is a kind of polymer material, has the very good complexing adsorption performance, and is good for heavy metal ion complexing adsorption, can effectively reduce the heavy metal ions poison of crops, and prevent it into the plant, and to protect the roots of flocked humic acid substances.
4. Enhance crops' resistance to disease, drought and waterlogging
Organic fertilizer contains vitamins, antibiotics, etc., can enhance crop resistance, reduce or prevent disease. The application of organic fertilizer into soil can enhance the water storage capacity of soil and drought resistance of crops.
At the same time, organic fertilizer can also make the soil become loose, improve the ecological environment of crop root system, promote the growth of root system, enhance root vitality, improve the ability of crop waterlogging resistance, reduce the death rate of plants, and improve the survival rate of agricultural products.
5. Improve the safety and green nature of food
The state has already made it clear that the excessive use of inorganic fertilizers must be restricted in the agricultural production process, and organic fertilizers are the main source of organic food.
Because all kinds of nutrient elements in organic fertilizer are relatively complete, and these substances are completely non-toxic, harmless and pollution-free natural substances, it provides necessary conditions for the production of high yield, high quality and pollution-free green food. The humic acid substance mentioned above can reduce the harm of heavy metal ions to plants, which is equivalent to reducing the harm of heavy metals to human body.
6. Increase crop yields
The beneficial microorganisms in organic fertilizer use the organic matter in soil to produce secondary metabolites, which contain a large number of growth-promoting substances.
If grow element, can promote plant elongation to grow, abscise acid can promote fruit to mature, gibberellin can promote blossom to set fruit, increase blossom number, fruit to keep rate, raise yield, make fruit full, colour and lustre is fresh and tender, still can go to market ahead of time, achieve increase production to increase gain.
7. Reduce nutrient loss and improve fertilizer utilization
The actual utilization rate of fertilizer is only 30% ~ 45%. Some of the lost fertilizer is released into the atmosphere, some is lost to soil erosion, and some is trapped in the soil and cannot be used by plants.
When organic fertilizer is applied, beneficial biological activities improve soil structure, increase soil water and fertilizer retention capacity, and thus reduce nutrient loss. With the addition of beneficial microorganisms to phosphorus and potassium, the effective utilization rate of fertilizer can be increased to more than 50%.
In conclusion, with the improvement of people's pursuit of food safety and quality of life, the development of green agriculture will accelerate the application of organic fertilizers in the future, and at the same time truly meet the requirements of sustainable development of modern agriculture.
