I learned today that potassium sulfate and potassium chlorid

Master Zhou is a garlic grower. He has been planting garlic for five or six years. He has gained a lot of experience in the planting process, but this time he has a question. Is it better to use potassium chloride or potassium sulfate to grow garlic? It turned out that when Master Zhou used potassium chloride as a base fertilizer this year, there were a lot of dead seedlings and rotten trees. This made Master Zhang have doubts. Can garlic use potassium chloride? Which is better, potassium sulfate or potassium chloride?
Potassium sulfate and potassium chloride are both commonly used potash fertilizers. Potassium sulfate is widely used. Because potassium chloride contains chloride ions, many crops are also very sensitive to chloride ions. As a result, the use of potassium chloride is subject to certain restrictions, which may be many Farmers cannot accurately determine which crops are more sensitive to chloride ions and have been using potassium sulfate, but the input cost will increase accordingly. We cannot judge from one aspect whether potassium sulfate or potassium chloride is good. We should consider the economic cost, crop types, and soil conditions. Which fertilizer is more appropriate?
In terms of economic cost, the price of potassium sulfate is higher than that of potassium chloride. Under the same crop and the same dosage, using potassium chloride is more economical than using potassium sulfate, and the effect is not very different. .
In terms of the types of crops, the growth of crops requires chlorine, but it will have an effect if it exceeds a certain amount, so some crops are chlorine-free crops. After using chlorine-containing chemical fertilizers, there will be a decrease in yield and quality. problem. For example, potatoes, sweet potatoes, yam, citrus, watermelon, and melon are all common chlorine-sensitive crops. When the chlorine content exceeds, the starch content will drop, the storage will not be tolerated, and the output will be low.
As far as the soil environment is concerned, potassium chloride is used in saline-alkali land all the year round. The chloride ion content in the soil will increase, and the salt content will increase. When it exceeds a certain amount, it will produce salt damage to the growth of fruit trees or vegetables. No matter what kind of fertilizer is used, the soil will be hardened all year round, the permeability will be poor, and the crops will appear dead and rotten.
Master Zhou has been planting garlic for five or six years, and the problem of repeated cropping will be very serious, so there will be a lot of dead seedlings and rotten trees. Garlic is not sensitive to chloride ions. If potassium chloride can be used correctly There is no such problem, and it has nothing to do with fertilizers. All along, farmers think potassium sulfate is better, because crops like garlic and spring onions are sulfur-loving crops, and the use of potassium sulfate can improve yield and quality. However, it does not mean that potassium chloride cannot be used for growing garlic.
For farmers, not all crops need to use potassium sulfate, should be used on crops that avoid chlorine. If you are planting crops that do not avoid chlorine, you can use potassium chloride on sandy soils, and potassium sulfate is preferred for sticky soils. If you generally use fertilizers such as potassium sulfate, you can change the formula and use potassium chloride next year. If you often use potassium chloride, you can try to change potassium sulfate.
Potassium sulfate and potassium chloride are two kinds of commonly used fertilizers, which can provide potash fertilizer for the growth of crops. When we choose, we should choose according to the needs of the crops and apply them reasonably, so as to achieve the effect of saving costs and increasing yield.
