A mixture of farm manure and chemical fertilizer can do a lot of good. Different kinds of crops have different characteristics and rules of fertilizer demand, and there are great differences in the proportion of nutrient demand. Although farm fertilizer contains more nutrients, a wide range of types, but the content is relatively small, it is difficult to reasonably supply and regulate a variety of physical nutrients. At the same time, due to its slow fertilizer effect, it is not conducive to the direct absorption of crops, and it is more difficult to meet the balanced demand of nutrients in different growth periods. Although the nutrient of fertilizer is relatively simple, the fertilizer effect is faster. The rational application of farm manure and chemical fertilizer, nutrients complement each other, slow and urgent fertilizer effect, is conducive to the balance of nutrient supply, to achieve good fertilizer effect. Farm fertilizer and fertilizer mixed distribution, available disc or hinge dragon scattering structure of the fertilizer truck (commonly known as the manure machine) to fertilize.
First, it can supply nutrients needed for crop growth. The characteristics of fertilizer are high nutrient content, quick fertilizer effect and short fertilizer duration. 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 fertilizer fully absorbed.
Two, can reduce nutrient fixation, improve fertilizer effect. After fertilizer is applied to the soil, some nutrients will be absorbed or fixed by the soil, thus reducing the availability of nutrients. When mixed with farmyard manure, it reduces the contact surface of the fertilizer with the soil and thus reduces the chance of being immobilized by the soil.
Three, can preserve storage, reduce loss, improve the nutrient absorption conditions of crops. With high solubility, fertilizer will cause higher osmotic pressure on the soil after application, affecting the absorption of nutrients and water by crops, which increases the chance of nutrient loss. If mixed with farm manure, it can avoid this malady.
Four, can adjust the soil acid alkaline, improve the soil structure. Farm manure is the raw material of microbial life, chemical fertilizer supplies inorganic nutrients for microbial growth and development, the combination of the two can promote microbial activities, and then promote the decomposition of organic fertilizer.
What's the difference between farm manure and fertilizer?
First, farm fertilizer contains a variety of nutrients needed by crops and rich organic matter, is a complete fertilizer, also called organic fertilizer. This kind of fertilizer comes from a wide range of sources, has long lasting strength, strong fertilizer retention ability, has the function of fertilizer cultivation and soil improvement, and the cost is low, has no adverse effects on soil and crops. The disadvantage is low nutrient content, slow fertilizer effect.
Second, chemical fertilizer is short for chemical fertilizer, raw materials are ore, air and water, products are mostly inorganic salts, so it is also called inorganic fertilizer. Advantages are high nutrient content, fast fertilizer effect, easy storage and use, the disadvantage is a single nutrient, small aftereffect. According to the effective nutrients contained in fertilizer, it can be divided into five types: nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, micro-fertilizer and compound fertilizer. Chemical fertilizer is an indispensable fertilizer in modern agriculture, scientific use of chemical fertilizer can not only improve the yield, but also improve the quality, can also play a role in fertilizing soil capacity.
