 What are the benefits of combining organic fertilizer and chemical fertilizer?
1. Chemical fertilizer has high nutrient content and fast fertilizer effect, but the duration is short and the nutrient is single. Organic fertilizer is just the opposite. The mixed use of organic fertilizer and chemical fertilizer can complement each other and meet the nutrient needs of crops in each growth period.
2. 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 agricultural fertilizers, it can reduce the contact surface of chemical fertilizers with soil, reduce the probability of chemical fertilizers being fixed by soil, and improve the effectiveness of nutrients. Chemical fertilizer is produced through a npk fertilizer manufacturing process. Some npk fertilizer manufacturing process can produce organic fertilizer because the fertilizer granulator used in the fertilizer production process can granulate organic fertilizer. For example, the fertilizer granulator used in the drum granulation production line is a drum granulator. The drum granulator can be used for compound fertilizer granulation or organic fertilizer granulation.
3. General chemical fertilizers are highly soluble and cause higher osmotic pressure on 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 overcome this drawback and promote the absorption of nutrients and water by crops.
 4. If only acidic fertilizer is applied to alkaline soil, after ammonium is absorbed by plants, the remaining acid roots will combine with hydrogen ions in the soil to form acid, which will increase acidity and increase soil compaction. If mixed with organic fertilizer, it can improve the buffering capacity of the soil, effectively adjust the pH, so that the acidity of the soil will not increase.
5. Because organic fertilizer is the energy source for microbial life, chemical fertilizer is the inorganic nutrition for the growth and development of microorganisms. The mixed use of the two can promote the vitality of microorganisms, thereby promoting the decomposition of organic fertilizer. The activities of soil microorganisms can also produce vitamins, biotin, nicotinic acid, etc., increase soil nutrients, improve soil vitality, and promote crop growth. The equipments required for biofertilizer production has technical requirements, because the addition of bacteria is subject to strict temperature and time restrictions.
Relevant departments also expressed that the use of organic fertilizers to replace some of the chemical fertilizers, reduce the amount of chemical fertilizers, and increase the amount of organic fertilizers, so that the combined use of organic and inorganic fertilizers is a scientific strategy for agricultural fertilization at present, and it is also the current and future direction and trend of fertilization! This is a very important way to improve soil fertility, protect agricultural environment, or stabilize soil fertility and increase yield.
