At present, the actual utilization rate of fertilizers in China is only 30% -45%, and even lower in some areas! When organic fertilizer is applied, beneficial biological activities improve soil structure, increase soil water and fertilizer retention capacity, thereby reducing nutrient loss and increasing the effective utilization rate of chemical 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. Now, the use of fertilizers and pesticides has been greatly reduced, and grain production has increased with much better quality than before. So the current reasonable fertilization method is to use organic fertilizer as the main fertilizer and chemical fertilizer as a supplement! 5 benefits of combining organic fertilizer with chemical fertilizer! Benefit 1: Chemical fertilizers have high nutrient content, fast fertilizer efficiency, but short duration and single nutrient. Organic fertilizers are the opposite. Mixing organic fertilizers with 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 farmyard manure, the contact surface between fertilizer and soil can be reduced, the probability of fertilizer 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 avoid this drawback and promote the absorption of nutrients and water by crops. 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 fertilizer, it can enhance 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 the decomposition of organic fertilizers. The activity of soil microorganisms can also produce vitamins, biotin, niacin, etc., increase soil nutrients, improve soil vitality, and promote crop growth.
