Is it true that cheap fertilizers and expensive fertilizers are much less effective? Why?

Expensive fertilizers are generally well-known brand fertilizers, low ones are generally produced and manufactured by small factories, the difference is quite large, it looks the same thing is actually very different, the raw materials used in well-known brand fertilizers are generally high-quality raw materials, they attach importance to the social effect, small factories care about profits, they do it today, tomorrow is not allowed to do anything, well-known brand fertilizers are their own production lines, the project investment is very large, they do it for a long time, small factories are OEM production, their own nothing, They are all authorized to entrust others to process, so they have no cost at all, and the profit is very large.

It is to dissolve the blended fertilizer again and granulate, and the granulation processing technology behind it has tyrosine, barrels, high-rise buildings, anchor sprays, and the manufacturers with the advantages of raw materials have more advantages, and there are no advantages of raw materials to buy back The production cost is high. The composition of chemical fertilizers is intended to be the composition of light fertilizers. For the same proportion of fertilizer, the cost difference is not large.

The fertilizer production process of well-known brands is strict, and the product cost will be higher, but the use experience is also stronger. If the price of the same fertilizer is very different, it only shows that the cost-effective fertilizer composition is far from enough. At this stage, because of the difficulty coefficient of control, many small manufacturers do have insufficient preparation.

Some manufacturers are short of 5-15 ingredients, each ingredient is about 50 yuan per ton, 5 is 250 yuan, and the cost difference between each bag is 15-45 yuan. The difference in the combination of nutrients. Reliable manufacturers and well-known brand products, especially at the level of water-soluble fertilizers and compound fertilizers, have solved the different nutrients that may be antagonistic during production, so as to prevent the antagonistic effect of chemical fertilizer thawing and reduce the use of chemical fertilizer.

However, it is usually not easy for some small manufacturers to take effective measures to prevent this situation, and the goal also depends on reducing the cost of reducing costs.

However, some fertilizer products are very different from the same type of fertilizer, which may involve the situation of raw materials, and the fertilizer brand with backup mining will have a cost advantage. If the price gap is good, there will be a possibility that the product quality will be different. Maybe it's the manufacturer stealing the ingredients, or maybe it's the best business that reduces the price for market sales.

Perhaps the farmers themselves have already changed the market positioning of the two models into more or less. Traditional chemical fertilizer, urea solution, potassium nitrate, diammonium phosphate, pure potassium fertilizer and other single fertilizers that do not have to be mixed, the price difference is small, only attention should be paid to the use of sodium chloride and ammonium sulfate in potash fertilizer in different terrain and landforms, and other practical effects are similar.

Yes, the effect of cheap fertilizer and expensive fertilizer is indeed very different, because the ingredients in these two fertilizers are different, the raw materials are different, the production process is different, and the effect is different.

Before analyzing the difference between "expensive" fertilizers and "cheap" fertilizers, let's take a look at a set of data comparisons: ammonium bicarbonate can be effective on the same day, and the validity period is only 15 days; Ammonium chloride is effective in 3 days, and the effective period is 25 days, and the phenomenon of "defertilization" often occurs in the later stage. Urea is effective in 7 days and lasts for 45 days; Compound fertilizer is effective in 10 days, and the effective period can generally reach more than 60 days; The controlled-release fertilizer is effective in 15 days, and the fertilizer effect period is more than 90 days.

So,""Expensive" fertilizer is expensive in terms of shelf life. "Cheap" fertilizer only does superficial articles, and gives you enough nitrogen, phosphorus, and potassium to make up enough amounts, and you can pass the inspection level.

Detailed description.

1. Blended fertilizer. A very beautiful fertilizer in a variety of colors. When you open the bag, you can see at least two colors, many of which are more bright colors, each representing a different nutrient particle.

Blended fertilizer is better than a fertilizer produced by mixing nitrogen, phosphorus and potassium together with fertilizers of other nutrients through a relatively simple processing method that is not too complicated and relatively simple. You can also think of it as a fertilizer formed by dyeing different fertilizers and mixing them together in proportion. Therefore, blended fertilizer is not a high-tech fertilizer, fertilizer efficiency response is general, fertilizer utilization efficiency is general, nutrient distribution ratio is diversified, nutrient composition is also more diversified, and it is relatively cheap.

However, there are also some more prominent blended fertilizers, and some slow-release or controlled-release processes will also be added to improve the utilization rate of fertilizers and prolong the fertilizer reaction time. It's just that this kind of blended fertilizer will be relatively high.

2. Compound fertilizer. Compound fertilizers are now the most widely used fertilizers. Including our commonly used diammonium, calcium ammonium nitrate and other fertilizers, can also be included in the category of compound fertilizers.

However, the compound fertilizer circulating in the market is a kind of fertilizer produced by taking the mineral source as the main raw material, through more advanced tower granulation, spraying granulation or ammoniation process, combined with some slow-release or controlled-release components. This type of fertilizer has uneven particles.

First, the color is consistent, and there are generally two or three kinds of nutrients. For this type of fertilizer, it is more suitable to be used as base fertilizer or seed fertilizer. Because it has the addition of slow-release or controlled-release ability, the release rate of fertilizer nutrients is relatively slow, and the duration of fertilizer effect is relatively long.

Therefore, this kind of fertilizer with relatively high scientific and technological content, relatively complex production technology and relatively high production technology is very popular with farmers.

Simple instructions. Simply put, compound fertilizer particles are more uniform, the color is consistent, the proportion of nitrogen, phosphorus and potassium nutrients is consistent and uniform, the crop absorption rate is high, but generally higher than compound fertilizer, and blended fertilizer is a simple nitrogen, phosphorus and potassium particles are physically mixed according to the content ratio, generally lower than compound fertilizer, blended fertilizer is mostly three color particles, one of the color particles only represents a nutrient, the absorption and utilization rate is low, especially after continuous use for 2 years, the fertilizer utilization rate decreases significantly, and the amount needs to be increased to meet the normal growth needs.

Because compound fertilizer is mostly made between 40-48, the raw materials that can be used here, such as ammonium chloride, monoammonium phosphate, etc., have the advantage of single nutrient **, so the same content can save money. BB fertilizer is generally bought with stable finished raw materials, and the nutrients are generally greater than 50. Therefore, it is difficult to refer to the copper content.

Simple identification method with chemical fertilizer:

1.Appearance identification.

Except for lime nitrogen, which is slightly light brown, the other nitrogen fertilizers are uniformly white crystals, and potassium fertilizers are white crystals, but Canadian potash fertilizers are reddish-brown. Phosphate fertilizers are generally powdery and mostly grayish-white or gray.

2.Solubility identification method.

Generally, nitrogen fertilizer and potassium fertilizer are soluble in water, while phosphate fertilizer is only partially soluble in water or insoluble in water, of which superphosphate is partially soluble in water and has a sour taste, while calcium, magnesium, phosphate fertilizer and phosphate rock powder are insoluble in water.

3.Reacts with alkaline.

Take a little fertilizer and mix it with the same amount of raw and hydrated lime, increase grinding, and can smell the pungent ammonia smell, then it is nitrogen-containing nitrogen fertilizer or compound fertilizer. Otherwise, it is a fertilizer that does not contain ammonia. (nitrogen fertilizers other than urea).

Organic fertilizer ** is generally around 500 1000. Bio-organic fertilizer** is more expensive.

The nitrogen, phosphorus and potassium content is about 5 10%.

Extended Materials. If organic fertilizer is mixed in the field, the organic fertilizer will become food for microorganisms, which is conducive to the reproduction of microorganisms. Organisms of different sizes, such as bacteria, fungi, insects, and earthworms, begin to move.

At this time, through the mucus secreted by microorganisms, the ionic structure becomes a small clump in the microscopic soil. Such a soil becomes an agglomerate structure, which is very suitable for the growth of crops.

Because of the space between the dumplings and the dumplings, they can make ventilation and drainage good. At the same time, the dumplings can also store water one by one, and the water retention is also very good.

There are many microorganisms in such soils, and they form a balance that pushes against each other. As a result, there will be no malignant microorganisms to multiply, just like the human gut, where beneficial microorganisms are balanced with harmful microorganisms. At the same time, crop damage mixed with organic fertilizer can increase the risk of pest and disease infestation.

The abundant harvest of Fengmyosaurus biological organic fertilizer is also plant-derived organic matter, and also contains humic acid, and more than a dozen kinds of medium and trace elements, ** is also within a reasonable range, not worse than any high-end organic fertilizer.

There are several reasons why online fertilizers** are cheaper than brick-and-mortar stores:1Sourcing directly from the factory or production site, eliminating the need for intermediaries.

Online fertilizers are generally purchased directly from manufacturers or production places, eliminating many links such as distributors and wholesalers, making it more favorable. 2.Strategy Pricing:

In order to attract and retain customers, many adopt strategic pricing, that is, sell low-priced fertilizers online first, attract more consumers with world suspicion, and quickly close the deal. Subsequently, through high-quality service and after-sales service, a repeat buyer will be left behind, so as to obtain long-term benefits. 3.

Lower costs: Traditional brick-and-mortar stores have to pay additional costs such as rent, utilities, and staff salaries, but they don't have to be considered. This is also why some ** can sell the product at a lower **.

4.Transparency: Through the Internet, users can easily browse and compare different merchants to obtain the best products.

Because of the greater transparency and the increased competition, the chemical fertilizers are correspondingly lower. In short, the low cost of online fertilizer is mainly due to factors such as direct procurement, removal of intermediate links, strategic pricing, transparency and low costs. However, as a consumer, you need to be cautious when purchasing, pay attention to details such as product quality, quality and after-sales service, and ensure that you buy high-quality products.

1. Increase the content of soil organic matter.

Regular application of organic fertilizer can significantly increase the content of soil organic matter, which is conducive to maintaining the stability of soil organic matter and improving the physical and chemical properties of soil.

2. Promote the formation of soil aggregate structure.

Soil organic matter, calcium carbonate and polysaccharides have a good effect on the stability of soil structure. The application of organic fertilizer can increase the content of soil organic matter more than the application of manure, especially the production of more five-carbon sugars, six-carbon sugars and polysaccharides. This is particularly beneficial for the formation of water-stable aggregates, such as a significant increase in water-stable aggregates that are larger than them.

3. Provide nutrients.

Organic fertilizer contains various nutrients required by crops, and the use of organic fertilizer can significantly increase the content of nutrients in the cultivated soil, especially potassium. In 1995, the Ministry of Agriculture surveyed the cultivated land in 12 provinces across the country, and found that the phosphorus content in the cultivated land increased compared with before 1990, while the cultivated land area lacking potassium and trace elements was expanded.

4. Regulate the nitrogen content of the soil**.

In the early stage of decomposing large straws, microorganisms absorb nitrogen from the soil to form their own somatic cells, resulting in the biological fixation of soil nitrogen, which plays a role in temporarily preserving nitrogen. When the microorganisms die, this part of the nitrogen is decomposed and released. In addition, the application of organic fertilizer increases the energy matter in the soil, and is also conducive to biological nitrogen fixation, the organic matter content in organic fertilizer can reach about 30%, and relevant data show that the energy released per carbon oxide can be used by nitrogen-fixing microorganisms to fix 10 40mg of nitrogen.

5. Improve the activity of soil microorganisms and soil enzymes.

After the application of organic fertilizer, the number of microorganisms increased significantly, especially in the soil near the application of organic fertilizer, which had a good effect on accelerating the release of organic nutrients and activating the nutrients in the soil. In addition, organic fertilizers can reduce diseases in certain crops.

Other advantages of the application of organic fertilizers in agricultural production include:

1. Nutritional balance, promote crop growth, increase yield significantly, and high fertilizer efficiency;

2. Improve the quality of agricultural products;

3. Inhibit pathogenic bacteria and reduce pests and diseases;

4. Loosen and improve the soil to reduce nitrate pollution in the soil;

5. Increase the absorption of water by crops, enhance the drought resistance and lodging resistance of crops;

6. After scientific management, the crops planted can reach the national green food fertilizer standard "A" or "AA".
