Common potassium fertilizer types and the best potassium fertilizer

What are the common types of potash and the best potash? Abstract: When it comes to potash, everyone is familiar with it, and it is also the most popular fertilizer now. Here, I would like to tell you a few secrets about what potash has to say...

1. What kind of potash?

Answer: Potassium fertilizer belongs to a strong acid salt, and its name is related to what acid root is corresponding to it. The corresponding nitrate is called potassium nitrate. The corresponding sulfate is called potassium sulfate, and the corresponding one is hydrochloric acid (also called hydrochloric acid). It is called potassium chloride, and the corresponding carbonate is called potassium carbonate, and the phosphate is called potassium phosphate (potassium phosphate, dipotassium phosphate, tripotassium phosphate, potassium polyphosphate, potassium polyphosphate, etc.), and organic acid radicals. The corresponding ones are called organic potassium (potassium formate, potassium acetate, potassium citrate, etc.), and the corresponding silicate is called potassium silicate...

2. Is potassium nitrate the best potash?

A: Non-also! Potassium nitrate is a tool used by water-soluble fertilizer companies to defeat compound fertilizer enterprises in that particular period (the chlorine-based and sulfur-based compound fertilizers are the dominant). It is a typical case of attacking opponents' weaknesses with their own advantages.

3. What potash is best?

A: The quality of the fertilizer is difficult to judge because there are too many factors involved. It is said that the public and the aunts are reasonable and can rank the price (KCl

4. What are the advantages and disadvantages of several common potash fertilizers?

Potassium nitrate, advantages: moderate price, good fast solubility, not easy to absorb moisture, neutral fertilizer, provide fast absorption of nitrate nitrogen; Disadvantages: dissolved heat absorption to lower ground temperature, easy to cause nitrite accumulation in crops under adverse conditions (organic agriculture It is forbidden to use. It is a nitrate and has certain safety hazards during storage and processing.

Potassium chloride, advantages: low price, high potassium content, good fast solubility, neutral fertilizer; disadvantages: dissolved heat absorption, easy to absorb moisture, chlorine, a large number of long-term application has certain side effects.

Potassium sulphate, advantages: low price, high potassium content, not easy to absorb moisture, can provide sulfur element; disadvantages: dissolved heat absorption, its own weak acidity, is a physiological acid fertilizer, the sulfur contained easily combine with calcium to form a slightly soluble substance Calcium sulphate can cause acidification and compaction of soil after application.

Potassium dihydrogen phosphate, advantages: not easy to absorb moisture, high total content of phosphorus and potassium, is the necessary raw material in high-content powder water soluble fertilizer; Disadvantages: dissolved heat absorption, its own weak acidity, is a physiological acid fertilizer, easy to move phosphorus It is fixed and can cause acidification and compaction of soil after application.

Potassium carbonate, advantages: high potassium content, alkaline, can reduce acidity and release CO2 after application, increase the concentration of local micro-environment CO2, enhance photosynthesis intensity; disadvantages: easy to absorb moisture, easy to flatulence, strong corrosive.

Organic potassium, advantages: Alkaline fertilizer can reduce soil acidity and provide a large amount of quick-acting carbon fertilizer; Disadvantages: easy to absorb moisture, high price.

Potassium polyphosphate, advantages: high phosphorus and potassium content, dissolution and exothermic, alkaline, good mobility of phosphorus, high utilization rate, acid reduction after application, fluffy soil, improved soil quality, and quick and long-term balance; Easy to absorb moisture, high price. After the advantages and disadvantages are finished, the choice is flexibly controlled by the specific circumstances.

5. Do you need to “solve potassium”?

A: NO! I often see that some packages have the word "phosphorus and potassium release". This is a kind of inertia. Potassium does not need to be solved because potassium salts are not water-soluble. Well, in the case of sufficient water, can't catch it and solve it? The key to potash is to protect it (envelope or polymer).

6. The more potash is used, the faster the fruit is opened?

A: Look at the situation. There are many factors and elements involved in the expansion of fruit (more on this later). In many cases, the fruit is not long, not potassium deficiency, but excessive potassium application.

Conclusion about potash

1. 1. There is no high or low level of potash fertilizer. Only the difference between the potash and the pot. The effect after application should be combined with the specific problems of water, temperature, crop and soil status.
2. 2. In the case of low temperature, high humidity, compaction, acidification and salting, it is recommended to apply potassium carbonate, organic potassium and (poly) potassium polyphosphate, and it is necessary to select a good period and apply it as many times as needed.
3. 3. Potassium is equivalent to the effect of sodium on humans to a certain extent. It is to regulate the osmotic pressure, maintain proper body fluid concentration, and promote the normal metabolism. It is critical to observe the growth of the crop, understand the soil condition, and accurately select the application. ("Moore Liquid Fertilizer" WeChat public number)
