Simple identification method for adding potassium The potassium chloride potassium in Canada is the longest and most used in the potassium chloride fertilizer for agricultural use in China. It is widely welcomed by farmers and becomes a brand product. At present, more than 70% of agricultural potassium chloride in China is “added potassiumâ€; domestically produced potassium chloride fertilizers imported from other countries are mainly used as potassium raw materials for producing compound fertilizer and potassium sulfate fertilizer. Therefore, the lawless elements sell fake potassium chloride, and often counterfeit the Sinochem brand "plus potassium" to benefit farmers.
In fact, Sinochem brand "plus potassium" and fake potassium chloride are easy to distinguish. About 30% of Sinochem's “addition of potassium†is red and 70% is white; if “potassium†is placed in water (fertilizer: water is about 1..10), after 3-5 minutes: “addition of potassium†Almost all dissolved; water turned into a transparent reddish color; "added potassium" remained in the original red and white grains during the dissolution process. If the fake potassium chloride is placed in the water, the above three phenomena will not occur at the same time.
Pseudo-potassium chloride is usually pretending to be sodium chloride or magnesium sulfate
Sodium chloride and magnesium sulfate are easily dissolved in water, and are easily purchased in large quantities on the market, and are also inexpensive, and are often used as raw materials for the manufacture of pseudo-potassium chloride. In fact, potassium chloride and sodium chloride are two different substances. Potassium chloride is mainly used as a potassium fertilizer, and sodium chloride is used as a raw material for salt and alkali.
The main difference between potassium chloride and sodium chloride is potassium and sodium. Potassium is one of the 16 nutrients necessary for crops. It is also one of the three major elements of nitrogen, phosphorus and potassium in China. Sodium is not a crop. The essential nutrients are not beneficial elements and cannot be applied as fertilizer. The application of sodium chloride as potassium chloride can have serious consequences for crop growth, burning roots, dead seedlings, and even causing serious salt damage in the soil. It takes many seasons to restore normal crop growth.
Magnesium sulphate is a chemical fertilizer containing magnesium nutrients. It is also an essential nutrient for crops. It is applied to the magnesium-deficient field and is beneficial to crop growth, but it cannot replace potassium chloride. Magnesium sulfate is a fake potassium chloride. If it is applied for a long time, it will destroy the soil structure, exacerbate the potassium deficiency, the leaves are yellow and yellow, the disease is more, the fruit is small, and the early maturity is reduced. The criminals also use bricks, ore particles, and other insoluble substances. After screening, they are coated with dyes such as ferrene to pretume potassium chloride fertilizer. This fake fertilizer is insoluble in water and easy to see.
The substance containing potassium chloride particles is not necessarily potassium
Agricultural potassium fertilizer must have the following conditions: high potassium content, obvious yield increase effect, no substances harmful to the soil, easy to apply. Therefore, potassium chloride particles containing unequal contents are not necessarily potassium fertilizers. Agricultural potash fertilizer must be approved by the relevant departments, and the fertilizer and packaging bags can only be sold in the market after meeting the required quality standards and requirements.
The same potassium fertilizer is applied, and the other nutrients are equivalent under the same conditions. The particle size of potassium fertilizer is not a direct factor affecting fertilizer efficiency. The large potassium fertilizer is used in long-term high-yield crops and fruit trees in the growing season to reduce the loss and enhance the aftereffect. The small potassium fertilizer is used in crops with shorter growth period. It is absorbed and promotes growth. Potassium fertilizer with too small particles, inconvenient fertilization, especially for spreading, is easily blown away by the wind, causing waste, and even hurting the seedling; the potassium fertilizer with too much grain is applied on the dry land, and the dissolution is slow, affecting the early potassium of the crop. demand. At present, the particle size of Sinochem plus potassium is more suitable, and farmers are more convenient to apply.
The potassium content of the fake potassium fertilizer is too low, it is not a potash fertilizer, it is a fake potassium fertilizer; some potassium content is higher, but it is much less than the standard content of the marked product, and it is a substandard product for cutting corners. The application of such products can cause severe potassium deficiency and reduced yield in crops.
Remedial measures after applying fake potassium chloride
The safe application of chemical fertilizers should be as follows: 1 Fertilizers should be applied to brand products that meet national standards; 2 Vendors of potassium chloride should do agrochemical services to help farmers apply scientifically and safely; 3 Farmers misuse false Fertilizers and fake potash should be remedied in a timely manner to reduce losses.
Most of the fake chemical fertilizers and fake potassium fertilizers do not contain NPK fertilizer components, or the content is very small, and will not cause fertilizer burning. Most of the safety problems are caused by different levels of NPK. In this case, NPK fertilizer should be added in a timely and appropriate amount, and then watered in time. Some of the fake fertilizers use sodium chloride and other saline-alkali substances, which are easy to cause dehydration and burning of crops. Watering should be done in time to dilute the damage of salt and alkali substances and reduce losses. Some industrial wastes for fake fertilizers contain heavy metals or toxic substances, and crops will suffer from large areas and even die, making it difficult to remedy. It is necessary to promptly send samples for testing, master the types of harmful substances, and take remedial measures to reduce the damage to soil and crops in the future.
