Amino acid organic fertilizer is a scientific formula, with soybean meal, cake, bone meal, fish meal, humic acid and so on as the main raw materials, adding highly active and beneficial biological bacteria (Japanese imported EM strains), and properly blending with amino acid raw powder and calcium, magnesium, sulfur, zinc, iron, boron and other micro elements. It syntheses the amino acid organic science into it, breaks the soil living environment of the root knot nematode and the harmful bacteria, and controls the occurrence of the crop disease, so it is very popular with the vegetable farmers. However, there are many kinds of amino acid organic fertilizer in the market, and the good and bad are different. The following methods can be used to identify the true and false.
1. see whether the fertilizer is certified by organic decayed maturity
Amino acid organic fertilizers must be thoroughly cooked before they can be sold, and the organic amino acids that are not decomposed can not be used for agricultural production. Most of the amino acid organic manure on the market has not been decomposed, can be identified by smell, and whether it has organic certification.
2. taste or not
Now, bentonite is added to a lot of fertilizer on the market. The cost of bentonite is low. The easiest way to identify or without bentonite is to taste it with mouth. If you feel a lot of bentonite after tasting it, it shows that there are more bentonite in the fertilizer. If you feel the taste of grain, this kind of fertilizer is more formal.
3. kneading manure test
Because the amino acid is extracted from the grain, open the package of fertilizer, grasp a fertilizer in the hands, hand knead like starch feel slippery, indicating that the product is less adulteration, if the feel is very rough, it is very serious adulteration.
4. look at the price of fertilizer
Take 40 kilogram of amino acid organic fertilizer as an example, plus some expenses, the price should not be less than 70 yuan, if the price is lower than the price, we should carefully weigh it.
5. see the fine density of fertilizer
The size of the real amino acid organic fertilizer particle is basically uniform. If we see that the size of the fertilizer granules is different, the other ingredients are added to the fertilizer. In addition, it can also be identified by color. Regular amino acid organic fertilizer is usually yellow. If the bentonite is added to the fertilizer, the color is generally white.
6. see whether the "three certificates" on the package of fertilizer are complete
"Three certificates" refer to production licenses, quality certificates and fertilizer registration certificates. "Three certificates" are essentially three systems formulated by the state to regulate the production and sale of compound fertilizers. "Three cards" do not fully indicate that they are not qualified or level to produce amino acid organic fertilizer, and the quality of their products is not guaranteed, so it is best not to buy them.
7. determine the content of amino acids according to the insecticidal effect.
Catch a fertilizer in the toilet, and come back after two or three hours to see if there are a lot of flies around the toilet, indicating that the content of the fertilizer is very low or not.
