First, it can fully supply the nutrients needed for crop growth. Fertilizer is characterized by high nutrient content, fast fertilizer effect, short duration, and relatively simple nutrient content. Farmyard manure is rich in nutrients but low in content, slow in fertilizer efficiency, and long in duration. Therefore, the combination of fertilizers and farmyard fertilizers can be used to make up for weaknesses.
Second, it can reduce nutrient fixation and increase fertilizer efficiency. After the fertilizer is applied to the soil, some nutrients are absorbed or fixed by the soil, which reduces the effectiveness of nutrients. If mixed with farmyard fertilizers, the contact surface between fertilizers and soil can be reduced, thereby reducing the chance of being fixed by the soil.
Third, it can conserve nutrients, reduce losses, and improve crops' absorption of nutrients. The solubility of chemical fertilizers is large. After the application, it will cause high osmotic pressure on the soil, affect the absorption of nutrients and water by crops, and increase the chance of nutrient loss. Mixing with farmyard fertilizers can solve this problem.
Fourth, the pH of the soil can be adjusted to improve soil structure. Farmyard manure can increase the buffer capacity of the soil, adjust the pH, so that the soil acidity is not too high.
Fifth, promote microbial activity, increase soil nutrients, and increase soil vitality. Farmyard manure is the raw material for microbial life. Fertilizer provides inorganic nutrition for the growth and development of microorganisms. The combination of the two can promote microbial activity, promote the decomposition of organic fertilizers, thereby increasing fertilizer efficiency. (Hubei Dangyang Agricultural 110 Service Center)
