Q: How should farmers friends know about compound fertilizer?
A: Compound fertilizer is one of the directions for the development of chemical fertilizers in China. It should be vigorously promoted and used. There is no doubt about this. Because compound fertilizer is a “technical combination†product, the technical content is scientific formula, different compound fertilizers are suitable for different crops and soils. If used properly, the fertilizer efficiency is of course good.
Q: Some farmers think that they can mix with single chemical fertilizers. What should be paid attention to when mixing fertilizers?
Answer: There are four aspects to pay attention to fertilizer mixing: 1) The physical properties of the fertilizer can not be deteriorated after mixing, and it is easy to apply; 2 The nutrients in the fertilizer can not be lost after mixing, which is beneficial to the effect of fertilizer; 3 Does not occur during transportation and mechanized fertilization The phenomenon of nutrient separation; 4 fertilizer mixture is beneficial to improve fertilizer efficiency and work efficiency.
Q: In order to use fertilizer well, please tell us in detail about the first aspect of fertilizer mixing?
A: The first point is that the physical properties of the fertilizer cannot be deteriorated after the fertilizer is mixed, in order to facilitate the application. This is often not understood by farmers. For example, urea and ordinary calcium phosphate cannot be mixed because the water contained in the phosphate fertilizer will come out after mixing, and the fertilizer will be deliquescent. In severe cases, the fertilizer will become "a muddy". Of course, such a fertilizer will be used. Can't be applied.
Q: What is the second aspect of fertilizer blending?
A: The second point of fertilizer mixing is that the nutrients in the fertilizer cannot be lost after mixing. For example, ammonium chloride, ammonium sulfate and ammonium hydrogencarbonate in the ammonium nitrogen fertilizer, if they are mixed with alkaline fertilizers such as lime and grass ash, will cause the nitrogen in the nitrogen fertilizer to become ammonia gas and volatilize and lose, thereby reducing the fertilizer efficiency. For example, 50 kg of chemical nitrogen fertilizer, after the mixing of nitrogen lost a lot, how can play the role of all fertilizers, of course, should not be mixed.
Question: So what is the third aspect of fertilizer blending?
A: The third point of fertilizer mixing is that if the size of the fertilizer particles is large when mixing, the uneven size of the fertilizer will occur during the storage and fertilization process, and the nutrient distribution will be uneven. Because the different sizes of fertilizer particles or the different weights of the particles will lead to uneven distribution of the whole fertilizer; thus, the nutrients cannot be balanced, which will inevitably affect the effect of fertilizer application.
Q: Finally, what do you mean by the fourth aspect of fertilizer blending?
A: The fourth point of fertilizer mixing is that it helps to improve fertilizer efficiency and work efficiency after mixing fertilizer. For example, organic fertilizer mixed with calcium phosphate can avoid the fixation of phosphate fertilizer in the soil, which is beneficial to improve the fertilizer efficiency of phosphate fertilizer. The application of the two fertilizers at one time is of course beneficial to improve work efficiency.
Expert tips
Fertilizer blending must follow the four principles of mixing.
Absolutely not any two fertilizers can be mixed.
The fertilizer to be mixed must be dry.
