First, the nutrients needed for crop growth can be fully supplied. The characteristics of chemical fertilizers are high nutrient content, fast fertilizer efficiency and short duration, and relatively simple nutrients. Most of the farm organic fertilizers are complete fertilizers, but the nutrient content is low, the fertilizer efficiency is slow and the duration is long. Therefore, the combination of chemical fertilizer and farmyard manure can be used to complement each other.
Second, it can reduce nutrient fixation and improve fertilizer efficiency. After the fertilizer is applied to the soil, some nutrients are absorbed or fixed by the soil, which reduces the effectiveness of the nutrients. If mixed with farmyard manure, it can reduce the contact surface between fertilizer and soil, thus reducing the chance of soil fixation.
Third, it can accumulate nutrients, reduce nutrient loss, and improve the nutrient absorption conditions of crops. Fertilizer has a high solubility and causes high osmotic pressure on the soil after application, which affects the absorption of nutrients and water by crops, which increases the chance of nutrient loss. If mixed with farmyard manure, this drawback can be avoided.
Fourth, it can regulate soil acidity and alkalinity and improve soil structure. Farmyard fertilizer can improve the buffer capacity of the soil, regulate acidity and alkalinity, and make the soil acidity not increase.
5. Promote microbial activities, increase soil nutrients, and increase soil vigor. Farmyard manure is a raw material for microbial life, and fertilizer supplies inorganic nutrients for microbial growth and development. The combination of the two can promote the activity of microorganisms, thereby promoting the decomposition of organic fertilizer.
