Potassium sulphate can be used as base fertilizer and top dressing. It is suitable for all kinds of crops, especially for chlorhexidine potassium crops.
The application of potassium nitrate to tobacco has an important effect of high fertilizer efficiency, easy absorption, promotion of early seedling growth, increase of tobacco yield, and improvement of tobacco quality.
Potassium dihydrogen phosphate is currently used for soaking seeds and top dressing.
Bio-potassium can be used for seed dressing, rooting, or in soil. The application of the microbial agent is actually inoculation of the root of the crop, allowing the silicate bacteria to release potassium, phosphorus, silicon, iron and other elements in the soil around the root system for absorption and utilization by the root system.

Pay attention to potassium fertilizer?
Applied by soil. Potash should be first placed on a plot of severe potassium deficiency. From the perspective of soil texture, the available potassium content of sandy soil is often low, and potassium fertilizer should be added; the available potassium content of clay soil is often higher, and it can be applied less or not. Potassium sulphate may be applied to soils deficient in potassium and sulphur-deficient, and potassium chloride may not be applied in saline-alkali soil.
Applied due to crops. It is applied to cash crops such as beans, potatoes, cotton and tobacco, and cereals such as cereals. In rainy areas or in areas with good irrigation and drainage conditions, potassium chloride can be applied to most crops, and a few cash crops should not be applied to improve quality.
Reasonable match. For tobacco, sugar crops and fruit trees, potassium sulfate is preferred; for fiber crops, potassium chloride is preferred. Due to the high cost of potassium sulphate, high-efficiency economic crop fields can be used. In general, in addition to a few chlorine-sensitive crops, it is preferable to use cheaper potassium chloride. (Liu Shu)
Where is the potash?
When the potassium crop is in the fast growing season, it is best to spray it on the foliage. For example, cotton is a potassium-producing crop. In the rapid growth period of cotton bolls, the amount of potassium transported by roots cannot meet the demand. At this time, spraying potassium fertilizer on the foliage of plants can make up for the situation of potassium deficiency and increase the yield of cotton wool.
When the roots of the crops are developed, it is best to apply them in depth. Commonly used conservation tillages leave more crop residues on the soil surface, and also cause higher concentrations of potassium to accumulate on the soil surface and not penetrate deep into the soil. When the soil moisture is good, these potassium can be infiltrated smoothly, but when the soil is dry, it will limit the absorption of potassium. Because the crop is rooted deeper below the potassium-rich soil layer in order to obtain sufficient moisture, this dislocation can lead to potassium deficiency in the crop. In this case, the deep application of potassium fertilizer can significantly increase the availability of potassium.
The location of other nutrients also determines how much potassium is accessible to crop roots. Nitrogen and phosphorus can stimulate the root branch of crops, and where these nutrient concentrations are high, the root ratio will be higher. Applying potassium fertilizer to nitrogen and phosphorus fertilizers in the same ditch can increase the chance of root contact with potassium.
