How to distinguish high quality water soluble fertilizer

Water-soluble fertilizer is a quick-acting fertilizer that can be quickly dissolved in water without residue and can be directly absorbed and utilized by the roots and leaves of crops. It can be applied to facility agriculture such as spray drip irrigation to achieve water and fertilizer integration. The effective absorption rate is more than 1 times higher than that of common chemical fertilizers, and the fertilizer efficiency is fast, which can solve the nutrient demand of high-yield crops in the rapid growth period. So how to distinguish high-quality water soluble fertilizer?

1, look at water soluble



Dissolve the fertilizer in clean water. If it is clear and transparent, it means that the water solubility is very good. If the solution is cloudy or even precipitated, the water solubility is very poor and cannot be used in the drip irrigation system.



2, smell the smell



Good water-soluble fertilizers are made from high-purity raw materials without any taste or a very light fragrance. Fertilizers with odors are either hormones or too much harmful substances. This fertilizer works quickly, but it does not have any benefit to the disease resistance and sustained yield and quality of the crop.



3, look at the registration number



The Ministry of Agriculture stipulates that all fertilizer products must implement one factory and one certificate, and it is not allowed to borrow certificates. The purchaser can visit the website of the National Fertilizer Quality Supervision and Inspection Center and enter the registration number to check the authenticity.



The difference between water-soluble fertilizer and flushing fertilizer:



Water-soluble fertilizer can not be confused with flushing fertilizer. It is also a kind of topdressing method. It is a method of topdressing fertilizer, which is to dissolve the fertilizer soluble in water and apply it as a top dressing.



Not all fertilizers can be used for fertilization. The fertilizer suitable for fertilization should have good water solubility, the nutrients are not easily solidified by the soil, the plants are easy to absorb, the fertilizer effect is fast, and there is no residual poison. For example, compound fertilizer, human excrement, etc., were not used for fertilization, and were diluted with water to form a liquid, which became a fertilizer.
