When
organic fertilizer is applied, the beneficial biological activities improve the soil structure and increase the soil's ability to retain water and fertilizer, thus reducing the loss of nutrients and increasing the effective utilization rate of chemical fertilizer to more than 50%. And also can reduce the amount of chemical fertilizer, reduce the cost of fertilization. In the UK, France and Japan, they have reduced the use of pesticides and chemical fertilizers since the 1970s and 1980s, and fertilization is mainly based on organic fertilizers, and now the use of chemical fertilizers and pesticides has been greatly reduced, and the yield of cereals has increased and the quality is much better than before. Therefore, the fertilization method of "organic fertilizer as the main fertilizer, chemical fertilizer as a supplement" is the most reasonable fertilization method at present!
5 benefits of organic fertilizer with chemical fertilizer!
Benefit 1: Chemical fertilizer has high nutrient content and fast fertilization effect, but short duration and single nutrient, organic fertilizer is the opposite, organic fertilizer and chemical fertilizer can be mixed to complement each other to meet the nutrient needs of crops in various growth periods.
Benefit 2: chemical fertilizer applied to the soil, some nutrients are absorbed or fixed by the soil, reducing the effectiveness of nutrients. After mixed with farm fertilizer, it can reduce the contact surface of fertilizer and soil, reduce the chance of fertilizer being fixed by soil, and improve the effectiveness of nutrients.
Benefit 3: General chemical fertilizers are highly soluble and cause high osmotic pressure to the soil after application, which affects the absorption of nutrients and water by crops and increases the chance of nutrient loss. If mixed with organic fertilizer, it can avoid this drawback and promote the absorption of nutrients and water by crops.
Benefit 4: If the alkaline soil is single application of acidic fertilizer, after the ammonium is absorbed by the plants, the remaining acidic roots combine with the hydrogen ions in the soil to produce acid, which will lead to enhanced acidity and increased soil consolidation. If mixed with organic fertilizer, it can enhance the buffering capacity of the soil and effectively regulate the acidity of the soil so that the acidity of the soil does not increase.
Benefit 5: Because organic fertilizer is the energy for microorganisms to live and chemical fertilizer is the inorganic nutrition for microorganisms to grow and develop. The mixture of the two can promote the vitality of microorganisms, which in turn promotes the decomposition of organic fertilizers. The activity of soil microorganisms can also produce vitamins, biotin, nicotinic acid, etc., which increase soil nutrients, improve soil vitality and promote crop growth.
