Benefit 1. Organic fertilizer contains a variety of nutrients and is a complete fertilizer: increasing the application of organic fertilizer is conducive to the balance of soil nutrient ratios, which is conducive to the absorption and utilization of soil nutrients by crops, and eliminates soil nutrient imbalance. In addition, organic fertilizer can also produce various phenols, vitamins, enzymes, auxins and other substances during the decomposition process, which can promote the growth of crop roots and the absorption of nutrients.
Benefit 2. Organic fertilizer contains a large amount of organic matter and is the food for the reproduction of various microorganisms in the soil. Because of the sufficient organic matter, the beneficial microorganisms in the soil can survive and multiply. At the same time, the beneficial microorganisms form dominant flora in the crop root system to protect the crop root system from the invasion of harmful pathogens, which reduces the occurrence of crop root diseases to a certain extent. In addition, the amount of organic matter content is an important indicator of soil fertility. The more it is, the better the physical properties of the soil, the more fertile the soil, the stronger the ability to retain soil, water and fertilizer, the better the ventilation performance, and the more conducive to the growth of crop roots.
Benefit 3. Using chemical fertilizer alone will aggravate soil acidification and salinization, destroy soil aggregate structure, and cause compaction. If mixed with organic fertilizer, it can improve the buffering capacity of the soil, effectively adjust the pH, and prevent the soil acidity from increasing.
Benefit 4. Chemical fertilizer has high nutrient content and fast fertilizer effect, but short duration and single nutrient, while organic fertilizer is just the opposite. If organic fertilizer is mixed with chemical fertilizer, it can complement each other and meet the nutrient needs of crops in various growth periods. In addition, after chemical fertilizer is applied to the soil, some nutrients are absorbed or fixed by the soil, reducing the effectiveness of nutrients. After mixing with organic fertilizer, the contact surface between chemical fertilizer and soil can be reduced, the probability of chemical fertilizer being fixed by the soil can be reduced, and the effectiveness of nutrients can be improved.
For soil: It is believed that everyone has a consensus that chemical fertilizer has a certain destructive effect on the soil after long-term use. Organic fertilizer can improve the soil, improve soil performance, and improve the efficiency of chemical fertilizer utilization. This is not available in chemical fertilizer!
From the perspective of soil cultivation and long-term benefits, the advantages of organic fertilizers are particularly obvious.
For crops: chemical fertilizers have huge nutritional functions. Without chemical fertilizers, there will be no high yields. Organic fertilizers are indeed inferior to chemical fertilizers in terms of direct nutrient supply to crops.
However, under the premise that chemical fertilizers are the main source of nutrition for crops, the main purpose of increasing the application of organic fertilizers is to regulate soil functions, create a good growth environment for crops, and increase the fertilizer nutrient absorption rate to a greater extent. This is very important.
According to expert research, physiological regulation functions are mainly undertaken by biological enzymes, intermediate metabolites, endogenous hormones, resistance substances, cell membrane components, metabolic absorption promoters, etc., and these components are only the most abundant in organic fertilizers.
In a word: chemical fertilizers provide food, while organic fertilizers regulate and maintain the stomach function of the soil, ensuring that it digests food better and more effectively. The two are completely incomparable.
Remember: chemical fertilizers simply provide nutrition (it only feeds, regardless of whether you digest it or not), while organic fertilizers are responsible for the digestive system of soil crops. If there is a problem with this system, no matter how much chemical fertilizer is used, it will be useless. Therefore, everyone should distinguish the different functions of chemical fertilizers and organic fertilizers, and never ignore organic fertilizers.
