In the past two years, organic fertilizers have developed rapidly under the strong support and promotion of the government!

According to a survey, a large number of farmers have reported a significant improvement in crop quality after using organic fertilizer!

The advantage is that it contains a variety of nutrients, a complete fertilizer with various large and trace nutrients, and active substances such as vitamins. Its prominent feature is that it can increase and supplement soil organic matter.

The organic matter in soil can significantly improve the physical and chemical properties of soil, improve soil tillage, enhance water permeability, improve soil water storage, fertilizer retention, fertilizer supply, and drought and flood resistance, and significantly increase yield, which cannot be replaced by chemical fertilizers.

In addition, organic fertilizers can provide the necessary nutrients for crops and protect their roots and stems; Enhance the disease resistance, drought resistance, and flood tolerance of crops; Improve crop yields; Improve the safety and greenness of food

We have discussed many benefits of organic fertilizers above. But even if its good, we cant just use it for farming because it has too few nutrients and cannot meet the nutritional needs of crops at different growth stages. We still need to use it in conjunction with fertilizers!

Everyone knows that excessive use of fertilizers is harmful and not beneficial! However, fertilizers have high nutrient content and quick effects (as long as they are used reasonably), which is still important for stable and increased agricultural production.

1. At present, the actual utilization rate of fertilizers in China is only 30% -45%, and even lower in some areas! After application, beneficial biological activities improve soil structure, increase soil water and fertilizer retention capacity, thereby reducing nutrient loss and increasing the effective utilization rate of fertilizers to over 50%. And it can also reduce the amount of fertilizer used and lower the cost of fertilization.

Britain, France, and Japan have been reducing the use of pesticides and fertilizers since the 1970s and 1980s, mainly using organic fertilizers. Although the use of fertilizers and pesticides has been greatly reduced now, grain production has increased and the quality is much better than before.

So the fertilization principle of "organic fertilizer as the main source, chemical fertilizer as a supplement" is currently the reasonable fertilization method!

2. The combination of organic fertilizer and chemical fertilizer has 5 major benefits!

Benefit 1: Chemical fertilizers have high nutrient content, fast fertilizer efficiency, but short duration and single nutrient. On the contrary, the combination of organic fertilizers and chemical fertilizers can complement each others strengths and weaknesses, meeting the nutrient needs of crops at different growth stages.

Benefit 2: After applying fertilizers to the soil, some nutrients are absorbed or fixed by the soil, reducing their effectiveness. After being mixed with agricultural fertilizers, the contact surface between fertilizers and soil can be reduced, the probability of fertilizers being fixed by soil can be reduced, and the effectiveness of nutrients can be improved.

Benefit 3: Generally, chemical fertilizers have high solubility, causing high osmotic pressure on the soil after application, affecting the absorption of nutrients and water by crops, and increasing the chance of nutrient loss. If mixed with organic fertilizer, it can overcome this drawback and promote crop absorption of nutrients and water.

Benefit 4: If only acidic fertilizers are applied to alkaline soil, after ammonium is absorbed by plants, the remaining acid ions combine with hydrogen ions in the soil to form acid, which will lead to increased acidity and soil compaction. If mixed with organic fertilizers, it can improve the buffering capacity of soil, effectively regulate acidity and alkalinity, and prevent soil acidity from increasing.

Benefit 5: Organic fertilizers are the energy source for microbial life, while chemical fertilizers provide inorganic nutrients for microbial growth and development. The combination of the two can promote the vitality of microorganisms, thereby promoting decomposition. The activity of soil microorganisms can also produce vitamins, biotin, niacin, etc., increase soil nutrients, improve soil vitality, and promote crop growth.

3. Zhang Taolin, Deputy Minister of Agriculture, stated that replacing some chemical fertilizers and reducing the amount of chemical fertilizers while increasing the amount of organic fertilizers is a scientific strategy for agricultural fertilization at present, and it is also the direction and trend of current and future fertilization! This is a very important approach for improving soil fertility, protecting the agricultural environment, and stabilizing soil fertility to increase yield.
