Many people are selling and recommending amino acid raw powder to various farmers. Amino acids do play a significant role in the growth of crops, and farmers all love to use them. Therefore, many farmers have the idea of trying to purchase and use this "pure amino acid amino acid raw powder". But does this amino acid raw powder really have a good effect on the growth of crops?
Today, let's talk about the tricks of agricultural amino acid raw powder!
Where does amino acid raw powder come from?
Most of the amino acid raw powder we use in agriculture is derived from animals. We extract amino acids from animal tissues such as chicken feathers, duck feathers and cowhide through processes like hydrolysis, ammonia deacidification, desalination and spray drying.
However, the process of amino acid extraction also has its own particularities. Many manufacturers sell amino acid raw powder, which is actually the by-product after amino acid extraction. Why is that? There are many types of amino acids, and the value of different amino acids varies. For instance, some relatively expensive amino acids include cystine, leucine, glutamic acid, etc. Cystine can be sold at 100,000 yuan per ton when it is expensive, and such expensive ones will be extracted in advance. The remaining amino acids, at this point, become by-products and are made into what we call "amino acid raw powder".
Many agricultural amino acid raw powders sold on the market cost less than 100 yuan for 10 kilograms. You can calculate this price yourself. As for those so-called amino acid raw powders, if we carefully look at the content on the packaging, most of them contain only about 30% to 40% free amino acids.
Amino acid raw powder should be used with caution in crops
Let's not deny the effect of amino acid raw powder on crops for now. It is still effective for some crops. It does contain a certain amount of free amino acids, which can promote the growth of crops. However, it should be informed to the growers here that the use of amino acid raw powder is limited and it has some disadvantages that the growers must be aware of:
1)In addition to containing some free amino acids, amino acid raw powder also contains a large amount of ammonium chloride (many amino acid raw powders are not marked as containing chlorine), because in the production process, ammonia gas is introduced to neutralize hydrochloric acid. The high content of ammonium chloride has a significant impact on chlorine-sensitive crops. Therefore, some chlorine-sensitive crops such as potatoes, sweet potatoes, sugarcane, watermelons, grapes, citrus fruits, apples, tea, Chinese cabbage, chili peppers, etc. should be used with caution!
2) Can amino acid raw powder preserve flowers and fruits and promote color change? Don't have too many illusions about the fact that dozens of kilograms of amino acid raw powder are sold for just over 100 yuan online. This amino acid raw powder is definitely a by-product. There are many amino acids inside, but not many of them are useful. Serine, arginine and other amino acids that promote flower and fruit retention are mostly destroyed during the amino acid extraction process. The most abundant one is glycine, whose main functions are to brighten leaves, promote chlorophyll synthesis and enhance photosynthesis. So it is not realistic to rely solely on this "cheap amino acid raw powder" to preserve flowers and fruits and promote flower bud differentiation.
3) Some farmers think that this is amino acid raw powder and when used in the seedling stage, it should be beneficial to the growth of the seedlings. This idea is both right and wrong. Firstly, it contains a high amount of chlorine and cannot be used on chlorine-sensitive crops. Secondly, it contains ammonium chloride. Using it at high temperatures can cause the seedlings to turn yellow and fail to grow. Therefore, it is recommended to use it with caution during the seedling stage.
If amino acid raw powder has these three disadvantages, does that mean it can no longer be used? Of course, it can also be used. After all, it still contains quite a lot of amino acids. For some chlorine-loving crops, using this is definitely fine. For some crops that are not sensitive to chlorine, it can also be used, but the dosage should be noted. The content of ammonia chloride and sodium chloride in amino acid raw powder is about 40%. Excessive use of amino acid raw powder may lead to excessive chloride ion content in the soil, which may cause root rot and other diseases in crops.
When using amino acid raw powder, it is recommended not to use it alone. The effect will be better when used in combination with compound fertilizers, etc. When purchasing, try to choose the one with a high content of free amino acids. Use it scientifically according to your crops to ensure the effect!
