In the previous article, the agricultural technology basket used a large amount of space to introduce you in turn - humic acid, amino acids, alginic acid, fish protein, these four products that have been very hot on the market in recent years, focusing on what they are and what effects they have on soil crops.
In the following article, the agricultural technology basket will continue to focus on it: (1) In the face of the mixed fish and dragons, the quality of products is uneven, how can we simply identify and judge the quality of humic acid, amino acids, alginic acid, and fish protein; (2) how to compare and distinguish the main functions between humic acid and amino acids, algic acid and fish protein. Only when everyone understands and understands it will they choose the right and use the right products, and can they spend less money and use more fertilizer.
First, how to simply distinguish the quality of humic acid, amino acids, alginic acid, and fish protein?
1. Humic acid quality identification method
(1) The implementation of the national standard on the outer packaging belt must be NY/T1106-2010, which is the industry standard for humic acid fertilizer issued by the Ministry of Agriculture of China.
(2) Where humic acid is added to the fertilizer, then the content of humic acid contained in the standard fertilizer can only be specified on the packaging bag, and only compound fertilizer or compound fertilizer can be written, and humic compound fertilizer or humic acid compound fertilizer cannot be written on the packaging bag.
(3) All fertilizers produced using humic acid or adding humic acid must clearly state the specific content of humic acid in the form of "≥XX%" on the outer packaging tape, otherwise it is an irregular unqualified product.
(4) Where humic acid fertilizer, the outer packaging must be a detailed crop application period and applicable amount of guidance, if not, it means that the purchase of this product is risky.
(5) Humic acid water solubility is better, if the humic acid in clean water can be quickly dissolved, and there is no sediment in the fertilizer, it means that this humic acid fertilizer is better, otherwise it means that the humic acid quality is not good.
(6) Water-soluble fertilizer and powder humic acid fertilizer in the water after the complete dissolution of the fertilizer color should be brown black or black brown state, if the fertilizer color is pure black, then it may be through the color of the counterfeit product; granular humic acid fertilizer by hand rubbing hard, there should be no discoloration phenomenon, if the color is lost, it means that there is a suspicion of dyeing fraud, if the granular humic acid fertilizer is smashed, if the fertilizer granules inside and outside the color are consistent black brown, it means that the fertilizer is better, If the color of the particles inside and outside is not the same, it means that the fertilizer quality is relatively poor, and it is likely that the product is counterfeited through dyeing.
(7) If the humic acid fertilizer is used in the ground to see the effect is relatively fast, the effect is better, indicating that the quality is better, if the effect is particularly slow after use, the effect is particularly poor, then congratulations you bought a fake humic acid fertilizer or a humic acid fertilizer that has not been activated (poor absorption, poor activity, poor quality, poor effect).
2. The quality identification method of amino acids
(1) Look at the implementation standards. The types of amino acid fertilizers on the market are basically water-soluble fertilizers, so the state has also introduced the corresponding industry standards for water-soluble fertilizers containing amino acids, therefore, when we buy amino acid water-soluble fertilizers, the first one needs to check whether the implementation standards on the fertilizer outsourcing bag are not NY1429-2010, if not, then do not have to look at the need to hurry up!
(2) Look at the dissolved state. Regular and qualified amino acid water-soluble fertilizer, should be fully water-soluble, no foam, no impurity precipitation of the fertilizer, if you buy amino acid water-soluble fertilizer in the water dissolved in water can not be fully dissolved in water, or there is insoluble impurity precipitation in the fertilizer, or water-soluble after shaking to produce a large amount of foam, then it means that the quality of the amino acid water-soluble fertilizer is unqualified.
(3) Look at the color of the fertilizer liquid. Quality qualified to meet the standard of high-quality amino acid water-soluble fertilizer, its fertilizer color normal looks should be black brown, tan or amber color, if you buy amino acid water-soluble fertilizer is pure black, dark black, beige, dark red, then congratulations on the success of buying fake and inferior amino acid water-soluble fertilizer.
(4) Smell the smell. Good amino acid water-soluble fertilizer should have no odor, if you buy amino acid water-soluble fertilizer smells of any foul odor, pungent smell or very strong ammonia smell, brown sugar smell, then it means that you bought fake and inferior unqualified amino acid water-soluble fertilizer, persuade you to throw it away quickly!
(5) See how many elements are added. The more types of amino acids used through chelating or complexation process, the more nutrients are added, the higher the production cost of such amino acid fertilizers, the better the nutritional effect, and the obvious comprehensive fertilizer effect after use, and vice versa.
3. Quality identification method of alginic acid
(1) Look at the implementation standards. China's national industry implementation standard for alginic acid fertilizer is the "alginic acid fertilizer" standard HG/T 5050-2016 officially implemented on April 1, 2017, this industry standard applies to all blended fertilizers, compound fertilizers, water-soluble fertilizers, coated urea, etc. with seaweed as raw materials (or added alginate synergists), this standard stipulates that the algic acid in fertilizers must be greater than or equal to 15% to be qualified.
(2) Look at the production of raw materials. Alginic acid is extracted from seaweed, but the amount of seaweed active ingredients in different seaweeds is more or less. The best raw material for algic acid extraction should be wild giant seaweed in the deep sea (such as deep-sea giant spirulina, bubble leaf algae, etc., less pollution, less harmful substances, and more endogenous active substances), but if you use shallow sea kelp extracted algic acid or produce seaweed fertilizer, it will be worse.
(3) Look at the appearance color. The normal color of alginic acid / fertilizer (such as powder) should be black brown or tan or algae brown or light brown to brown powder or flake powder, if you buy alginic acid is other colors (such as pure black), then this product is likely to use other raw materials to impersonate or add raw unqualified products, the purpose of this is mainly to reduce production costs, for huge profits.
(4) Look at the outer packaging standards. All qualified algic acid products, such as adding a variety of water-soluble fertilizers, compound fertilizers, mixed fertilizers, enveloping urea, etc., should be clearly marked on the packaging bag with the implementation of the standard number, registration certificate number and specific extraction process and production art (enzyme solution is good), alginic acid content (the amount of addition is not enough to poor effect) and other information, if there is no such thing on the packaging bag, or only write seaweed extract or trehalin and other words, then the quality of such products will not be good
(5) Smell the smell. Alginic acid or seaweed fertilizer produced using high-quality raw materials will generally have a natural light seafood smell (like the smell of seaweed eaten by children), but if you buy alginic acid or alginic acid fertilizer that smells like a strong pungent or foul odor, or smells a little odor, it is the use of poorer products, either its production raw materials are relatively poor, or it is produced with hormones, or it is produced by using a lower low price of humic acid.
(6) See the validity period. Alginate fertilizer used in field crops, and will not see the immediate effect in a short period of time, generally need to wait one to two weeks to see the obvious effect, if you buy alginic acid within a few days after the use of immediately into school, then this product may not be a good product, it may be added to the hormone algic acid (fertilizer).
4. The quality identification method of fish protein
(1) There is no national industry implementation standard for fish protein, only enterprise standards. Although the product of fish protein has been relatively hot in the market in recent years, but according to the agricultural technology basket: the state has not yet introduced the corresponding national industry implementation standards for fish protein fertilizers, and all the fish protein products on the market are implemented by the enterprises themselves, which is still a bit regrettable, and I hope that the state can introduce national standards as soon as possible to regulate the industry.
(2) Smell the smell. Fish protein production raw materials in the ocean, shrimp, so the regular fish protein products should smell with a natural light fishy smell, if you buy fish protein products smell no fishy smell or pungent odor, indicating that such products are the use of inferior raw materials (such as the use of rotten fish and shrimp after squeezing juice water production) or other additives (such as the use of hormones or humic acid blending) and other production of fake and inferior fish protein products.
(3) Look at the raw materials. The best quality fish protein products should be the use of fresh deep-sea high-quality fish extract production of fish protein products, in addition to some of the high-end fish protein products with ridiculously high prices, most of the fish protein products on the market are produced using small fish shrimp or fish scraps (such as fish skin, fish scales, fish offal, etc.), so if you buy a fish protein product that is known as "deep sea fresh fish" at a very low price, then the quality of this product will certainly not be very good, and there is a suspicion of counterfeiting or excessive publicity.
(4) Look at the packaging. The use of formal process technology (such as enzymatic lysis, hydrolysis, mycolysis, etc.) and regular raw materials to produce fish protein (such as fresh fish and shrimp raw materials) generally will not appear bulging bags, bulging bags, swelling barrels and other problems, but if the use of rotten raw materials or inferior raw materials to produce fish protein products, because the active substances in the raw materials have been basically fermented decomposition loss too much (no active fish protein has no effect), and a large amount of volatile nitrogen gas has accumulated in the fertilizer, so it will occur to make the outer packaging bulge and expand. Such yields are not only of poor quality, but also very likely to cause problems such as burning seedlings or aggravating soil salinity after use.
Second, on the simple effect comparison of humic acid and base acid, alginic acid and fish protein
1. About the comparison between humic acid and amino acids
Humic acid and amino acids both contain organic matter, which looks like similar things, but in fact the two are two different substances, and the two cannot be compared together, because the two are fundamentally different in function. In general, the main functional role of humic acid is reflected in the regulation of efficiency, while the main function of amino acids is reflected in the focus on crop health.
Humic acid belongs to the category of biological growth regulators, which have a regulatory effect on crop growth, have a synergistic function for various types of fertilizers, and have a role in improving and repairing the soil, while amino acids belong to substances that improve the nutritional balance of crops, and have obvious effects on promoting the rapid absorption of various nutrients by crops, improving the absorption and utilization rate of nutrients by crops, enhancing crop photosynthesis ability, enhancing crop stress resistance, and improving crop product quality.
2. About the comparison between algic acid and fish protein
On the one hand, although alginic acid and fish protein are both marine resource extracts, the raw material for the production of algic acid is marine plants (seaweed), while the raw material for fish protein production is marine animals (fish and shrimp).
On the one hand, algic acid contains a large number of nitrogen-containing organic matter, but also contains a large number of non-nitrogen organic matter and rich marine mineral elements (such as potassium, calcium, magnesium, zinc, iron, manganese, etc.), and the main component of fish protein is rich in nitrogen-containing organic matter. Therefore, alginate can help crops absorb nutrients faster and more comprehensively, avoiding the occurrence of deficiency in growth, while fish protein can stimulate crops to grow and develop faster.
On the other hand, because the extract of alginic acid has a large number of plant endogenous hormones (such as cytokinin, gibberellin, abscisic acid, ethylene, etc.), it can better regulate crop growth, but also faster crop absorption and utilization, which is incomparable to fish protein, so algic acid is also faster and better than fish protein in terms of effectiveness.
On the other hand, because algic acid contains a variety of hormone substances that promote crop growth, after being used on crops, if it encounters emergency bad weather (such as high or low temperature), it can effectively enhance the ability of crops to adapt to the external adverse environment. Because fish protein contains more active proteins, it can also stabilize the cell membrane structure and enhance leaf photosynthesis on the basis of increasing unsaturated fatty acids and other substances for crops, so fish protein is helpful to enhance the growth of crops and enhance the cold resistance of crops.
Finally, the effect of alginic acid is generally better than fish protein, but the price is also much more expensive than fish protein as a whole, if you have the conditions, the agricultural technology small back basket first recommends algic acid to everyone, if you encounter bad weather suddenly when it is recommended to use alginic acid (fast effect, good effect), if it is just to make the crop grow better, the yield is higher, then the agricultural technology small back basket recommends that you still choose to use fish protein, because the input cost of using fish protein is relatively lower!
