Fertilization refers to the agricultural technical measures that fertilizer is applied to the soil or sprayed on plants to provide nutrients needed by plants and to maintain and improve soil fertility.

What are the advantages of reasonable collocation of farm manure and chemical fertilizer?

Mixing farm manure with chemical fertilizer can do a lot of good. The fertilizer requirement characteristics and rules of different kinds of crops are different, and the demand proportion of various nutrients is quite different. Although farm manure contains comprehensive nutrients and a wide variety of nutrients, the content is relatively small, so it is difficult to reasonably supply and adjust all kinds of nutrients necessary for physics. At the same time, because its fertilizer efficiency is slow, which is not conducive to the direct absorption of crops, it is more difficult to meet the nutrient demand in different growth stages. Although the nutrient of chemical fertilizer is relatively simple, the fertilizer effect is faster. The reasonable collocation application of farm fertilizer and chemical fertilizer can complement each other and help each other with slow and urgent fertilizer effect, which is beneficial to the balanced supply of nutrients and achieve good fertilizer effect.

First, it can fully supply the nutrients needed for crop growth. Chemical fertilizer is characterized by high nutrient content, fast fertilizer effect and short duration, and single nutrient; agricultural organic fertilizer is mostly complete fertilizer, but the nutrient content is low, the fertilizer effect is slow and the duration is long. Therefore, the mixed application of chemical fertilizer and agricultural organic fertilizer can learn from each other and make the nutrient elements in the fertilizer fully absorbed.

Second, it can reduce nutrient fixation and improve fertilizer efficiency. After chemical fertilizer is applied to the soil, some nutrients will be absorbed or fixed by the soil, thus reducing the availability of nutrients. If mixed with farm manure, the contact surface between chemical fertilizer and soil can be reduced, thus reducing the chance of being fixed by soil.

Third, it can preserve, reduce the loss and improve the conditions of nutrient absorption by crops. The solubility of chemical fertilizer is high, which causes high osmotic pressure to the soil and affects the absorption of nutrients and water by crops, which increases the chance of nutrient loss. If mixed with farm manure, this malady can be avoided.

Fourth, it can adjust the acidity and basicity of the soil and improve the soil structure. Farm manure is the raw material of microbial life, chemical fertilizer provides inorganic nutrition for the growth and development of microorganisms, the mixture of the two can promote the activity of microorganisms, and then promote the decomposition of organic fertilizer.

What is the difference between farm manure and chemical fertilizer?

First, farm manure contains a variety of nutrients and rich organic matter needed by crops, which is a kind of complete fertilizer, also known as organic fertilizer. This kind of fertilizer has a wide source, long stamina, strong ability to preserve fertilizer, has the effect of improving fertilizer and soil, and has low cost, and has no adverse effect on soil and crops. The disadvantage is that the nutrient content is low and the fertilizer effect is slow.

Chemical fertilizer is the abbreviation of chemical fertilizer, the raw materials are ore, air and water, and most of the products are inorganic salts, so they are also called inorganic fertilizers. The advantage is that the nutrient content is high, the fertilizer effect is fast, and it is easy to store and use, but the disadvantage is that the nutrient is single and the stamina is small. According to the available nutrients, chemical fertilizer can be divided into five types: nitrogen fertilizer, phosphate fertilizer, potash fertilizer, micro-fertilizer and compound fertilizer. Chemical fertilizer is an indispensable fertilizer in modern agriculture. Scientific use of chemical fertilizer can not only improve yield, but also improve quality. It can also play a role in improving soil fertility.
