How to judge the authenticity of soybean meal organic fertilizer

Soybean meal organic fertilizer fermented organic fertilizer has a special aromatic flavor, which is not pungent.

The test method of soybean meal powdered organic fertilizer is to put the powdered organic fertilizer directly in a glass of water, if it is floating, then it is a qualified organic fertilizer, if it sinks directly, then this organic fertilizer may have problems, because organic matter is lighter than water. To detect granular organic fertilizer, it is to put it in water to see the solubility, under normal circumstances, the more precipitation, the better, the higher the solubility, the better.

The following methods can be used.

One touch: slippery and dry, and it is high-quality fertilizer that can be scattered when you touch it.

Second smell: If there is a little fragrance and sake lees smell, it is better to rot.

Three looks: the off-white is over-rotten, and it is generally not recommended to choose. Semi-decomposed organic fertilizer is used in the field, which continues to decompose in the ground and can be combined with organic matter in the soil to form new humus, which has a better effect.

It should be noted that the action period of organic fertilizer is relatively long, and it also takes a process to fertilize the soil.

When looking at the raw materials, it is necessary to understand whether the raw materials used in the product are of high quality. At present, the better organic raw materials used by organic fertilizer manufacturers are soybean meal, sesame meal, sugar residue, cassava residue, bacterial protein, amino acids, humic acid, smoke foam, etc., and some also add bone meal, shell powder and other calcium raw materials to increase calcium content, which has a significant improvement effect on fruit tree bitter pox disease and water heart disease. ‍

Second, see whether the proportion of microbial strains is scientific. The enzyme activity of the excellent strains is relatively high, and the enzyme activities of cellulase, xylanase, polygalacturonidase, polygalactose lyase, etc., which can meet the requirements of industrial strains and have strong tolerance. Through the addition of excellent microbial agents, the decomposition cycle can be greatly shortened and the decomposition effect can be improved.

Third, see whether the manufacturer's production line process is strict. The whole production process of commercial organic fertilizer can be summarized as ingredient - decomposition - granulation - cooling - screening - packaging, in which the degree of decomposition is extremely important. Good products have high maturity and long-lasting fertilizer efficiency; Products that are not well rotted can easily cause crops to burn.

The application of commercial organic fertilizers can reduce the amount of chemical fertilizers used, thereby reducing the adverse environmental effects of chemical fertilizers. The production process of organic fertilizer is also a process to solve the resource treatment of urban and rural organic waste, and turn waste into treasure. In addition, the application of organic fertilizer can increase the content of organic matter, enhance the adsorption of heavy metals and pesticides in the soil, and reduce its harm.

Organic fertilizer for soybean meal is just a statement. 1 kg of soybean meal can be called soybean meal organic fertilizer when added to 1 ton of organic fertilizer. Hehe, so, the way to judge the truth or falsehood is: test.

1 kilogram of soybean meal is less than 4 pieces, grandma, who is willing to use it

Who would be willing to make organic fertilizer from soybean meal?

This one is not ordinarily strong.

Since it is said to be organic fertilizer, the country has relevant standards.

Organic matter》30% NPK/5% Moisture is not much to remember.

According to the national standard, send it to the relevant institutions for testing, and you will know whether it will work or not.

Soybean meal is indeed very expensive, but the organic fertilizer will also be very good, because the organic fertilizer content will be very high, if mixed with other excipients, the content will be greatly discounted, it is recommended to take a look at Baoding Boxin organic fertilizer, the content of the production exceeds the national standard, the fertilizer effect is long, and the effect is good.

Soybean meal is very expensive, to really use the organic fertilizer content of soybean meal will be very high, Baoding Boxin organic fertilizer production of soil force soybean meal pepper cake organic fertilizer, organic nitrogen, phosphorus and potassium content of 6%, organic matter 50%, you can pay attention to it.

1. The soybean meal will be crushed with a sedan car, the fake soybean meal is dusty, and the dust will adhere to the bottle wall when it is packed into a glass bottle, while the pure soybean meal does not have this phenomenon.

2. Soak the soybean meal in a glass filled with water for 2 3 hours, then gently stir it with a wooden stick, and observe it after standing still, if it is mixed with other lighter substances, it will float on the upper layer; If it is mixed with stone powder, etc., there will be precipitation in the lower layer.

3. The packaging volume of adulterated soybean meal may be smaller than normal. The volume weight measurement can be taken after the sample is divided into quarters, and then the sample is gently put into the 1000ml graduated cylinder to make it exactly to the 1000ml scale, and then the sample is poured out of the graduated cylinder and weighed. Each sample was repeated 3 times, and the average value was taken as the bulk density.

Generally, the bulk density of pure soybean meal is 594-610g l, if the measurement result is quite different from this result, it means that the soybean meal is adulterated.

4. Take a small amount of soybean meal and lay it in a clean place, drop a few drops of iodine wine on it, and after a few minutes, if any of the substances turn blue-black, it may be mixed with corn, bran, etc.

<> real organic fertilizer is generally gray-brown or dark black, and the powder is loose, while the color of fake organic fertilizer is bright black, the powder is denser, and the density is relatively large; Add 30-50 grams of organic fertilizer to water and dissolve and stir for 1 minute, after standing for 10 minutes, the real organic fertilizer water is the original ecological soil brown, precipitated at the bottom of the cup, and the fake organic fertilizer water is turbid black; Burning with fire, real organic fertilizer is easy to burn, and the smoke is grayish-white, and fake organic fertilizer is difficult to burn, and the smoke is black.

First of all, the general raw materials of high-quality organic fertilizer are selected from high-quality straw, cow manure, pig manure, sheep manure, etc., with a total nutrient content of about 5%, and the kneading dough is scattered, and the color of the organic fertilizer after full decomposition is black and brown.

Then, the easiest way to identify organic fertilizers is to blister them with water. After soaking in water, the organic matter and impurities in the organic fertilizer will be stratified, the organic matter usually floats in the upper part, while the impurities such as sediment are precipitated in the lower part, and the organic fertilizer with more precipitation in the lower part is of poor quality.

Secondly, distinguish the advantages and disadvantages by the weight of organic fertilizer. For the same organic fertilizer, high-quality organic fertilizer is generally lighter because it contains more organic matter; Inferior organic fertilizers are generally heavier due to more mixed sediment.

Finally, you should also check the pH test strip when purchasing, and it is better to have a pH value of around 7. Soak the organic fertilizer with a small amount of water, dip a small amount of fertilizer solution with pH test paper, and then compare it with the standard color card to determine the pH of the organic fertilizer.

There are roughly 3 simple points to distinguish:

1. A look: high-quality bio-organic fertilizer is generally made of high-quality chicken manure as raw materials, with higher nutrients, relatively loose, and black-brown in color. Inferior organic fertilizers are generally black in color and not loose enough.

2. Second bubble: authentic granular organic fertilizer will be dissolved in water in a short time, the color is gray and black, but there are no impurities; Fake ones will have a large number of impurities that do not dissolve in water.

3. Sanliao: put a small amount of organic fertilizer on the iron plate and place it in the fire source, in a short time, the genuine product will smoke and coke, and there will be few residues; Fake ones leave a lot of residue behind.

1. Check whether the packaging has a secondary sealing phenomenon, and the regular manufacturers avoid leakage mostly for double-line packaging, whether the packaging and printing are clear, and whether the material is coarse.

2. The color of pure soybean meal is consistent, light yellow to light brown, irregular fragments, occasionally a small amount of clumping, and bean flavor.

3. Grab a handful of soybean meal and stretch out your palm to sieve gently, remove the larger flake soybean meal on the top, and put the smaller one in your mouth, chew it slowly.

4. Take away the neat and large particle size, and rub the small ones by hand, even if the real soybean meal is fine, it is not fine, and the fake soybean meal can be rubbed out of white powdery substance.

Characteristics: Through plant breeding, plant varieties with low or no anti-nutritional factors are cultivated and the quality of soybean protein is improved, but the yield of these soybeans is relatively low, so it is relatively difficult to promote.

On the other hand, through animal breeding, the tolerance of livestock to trophic factors is improved; Through transgenic breeding, strains that can secrete and digest anti-nutritional factors can be cultivated to eliminate the anti-nutritional effects of anti-nutritional factors on livestock and poultry. However, there are problems such as low yield, reduced disease resistance, long cycle and large investment.

Answer Appearance Identification Method. Pure soybean meal is irregular fragments, light yellow or light brown, consistent in color, occasionally a small amount of lumps, and smells of soybean meal's inherent bean flavor. If the color is golden and the grains are uniform, it is good soybean meal that has a bean aroma and smell.

On the contrary, if the color is dark, the particles are uneven, and there is a mildew smell, it may be mixed with zeolite powder, corn and other impurities. The soybean meal mixed with impurities is light in color, the color is different, the agglomeration is more, after peeling it off, twist it with your fingers, you can see the white powder, smell it slightly bean fragrance, doping amount is large, then there is no bean fragrance. If the fake soybean meal is crushed and compared with the soybean meal, the color difference is even more obvious, and the real product is light yellow-brown.

During the crushing process, the fake soybean meal is dusty, and the dust will adhere to the bottle wall when it is packed into a glass container; This is not the case with pure soybean meal. Outer packaging identification method. After adulteration of impurities in the feed, most of the packaging is small in size and increases in weight.

Immersion identification. Soak the soybean meal in a glass filled with water for 2 3 hours, then gently stir it with a wooden stick, if adulterated, you can see the layering, the upper layer is soybean cake, and the lower layer is sediment. Iodine wine identification method.

Take a little soybean meal and put it in a clean enamel dish, spread it thinly and flatten, and then drop a few drops of iodine wine, after a few minutes, if any of the substances in it turn blue-black, it means that it may be mixed with corn, bran, rice husks, etc.

How to identify the authenticity of soybean meal Soybean meal is the residue of soybean oil after pressing, the protein content is very high, usually above 40, is the best plant protein feed raw materials used in the processing of feed, the current soybean meal ** stable, some criminals in order to make profits, sediment, zeolite powder, corn kernels, corn stalks and other substances mixed with pure soybean meal, pressed into pieces by machine, and then crushed to make fake soybean meal that looks very similar to immature beans. Due to special processing, the appearance of this adulterated soybean meal is very similar to that of pure soybean meal, but there are more clumps, and the soybean flavor is very light or no soybean flavor. If it is not carefully identified, it is easy to be fooled and cause great economic losses to the majority of users.

The simple identification method of soybean meal is introduced as follows. Appearance identification method Appearance inspection refers to the identification of the appearance shape, particle size, color, odor, texture and other indicators of feed with human sensory organs. Soybean meal is flaky or powdery and has a bean flavor.

Pure soybean meal is irregular fragments, light yellow to light brown, consistent in color, occasionally a small amount of lumps, and smells the inherent soybean flavor of soybean meal. If the color is golden and the grains are uniform, it is good soybean meal that has a bean aroma and smell. On the contrary, if the color is dark, the particles are uneven, and there is a mildew smell, it is not a good soybean meal.

After mixing zeolite powder, corn and other impurities, the color is light, the color is different, the agglomeration is more, after peeling it off, twist it with your fingers, you can see the white powder, smell it with a little bean fragrance, and there is no bean fragrance if the amount of doping is large. If the sample is crushed and compared with soybean meal, the color difference is even more obvious, and the genuine product is light yellow-brown. During the crushing process, the fake soybean meal is dusty, and the dust will adhere to the bottle wall when it is packed into a glass container, while pure soybean meal does not have this phenomenon.

Chewing on soybean meal with teeth is sticky, while corn is crispy and powdery. Outer packaging identification method Fine particles, large capacity, low quality, which are the common characteristics of most dopants. When the feed is adulterated with such substances, the packaging volume must be small and the weight increases.

Soybean meal is usually packaged in 60kg, and after being doped with a large amount of zeolite and other substances, the packaging volume is smaller than normal. Water immersion identification method take 25 grams of soybean meal (cake) to be tested, soak it in a glass filled with 250 ml of water for 2 hours 3 hours, and then gently stir it with a wooden stick.

Hello dear. I'm glad I answered for you. A:

1. Soybean meal bio-organic fertilizer is an organic fertilizer processed from manure, and the organic fertilizer has good water solubility. 2. Its nitrogen, phosphorus and potassium have good water solubility, and most of the raw materials are easy to be absorbed by plants, and there will not be too many residues. 3. In addition, organic fertilizer will also add organic matter to the soil, adsorb cations, and improve the moisture status of the soil.

4. Soybean meal is a good raw material for organic fertilizer. 5. The organic matter content is very high, and an appropriate amount of livestock and poultry manure can be added, such as chicken manure, pig manure, etc., to supplement sufficient nitrogen, phosphorus and potassium nutrients, and adjust the appropriate carbon-nitrogen ratio (the most suitable carbon-nitrogen ratio for crops is 25:1 30:

1), and a variety of microorganisms that promote decay have been added.
