Potassium chloride, potassium hydrochloride, the main potash fertilizer, red-brown granules. It is highly soluble in water. Suitable for all agricultural crops, except for those sensitive to chlorine. When interacting with the soil absorbing complex, it has an acidifying effect on the soil solution, especially in acidic soils. As a result of metabolic reactions, hydrochloric acid is formed in the soil. Therefore, the effectiveness of potash fertilizers is reduced on acidic soils. At the same time, the physiological acidity is lower than that of ammonium fertilizers and is only manifested when high doses are applied for a long time to crops that take a lot of potassium out of the soil.
In the soil, potassium ion quickly interacts with colloidal soil particles by physicochemical (exchange) and non-exchange absorption. The absorption of potassium by the soil is almost complete within a day after the application of potash fertilizers, so it almost does not depend on the length of time between the application and sowing. As a result, potassium mobility in the soil and the likelihood of leaching are reduced. Potassium is readily available to plants, and its utilization rate is quite high – up to 70%. Potassium chloride has good physical properties, is low-hygroscopic, does not caking, is easily dispersed, and is highly soluble in water.
Application
Potatoes, sugar beets, barley, sunflower, buckwheat, millet, some types of vegetables and other crops are the most demanding in terms of potassium consumption and provide the highest effect from its use. Potassium chloride is recommended for light soils: loams and sandy loams. It is effective in growing potatoes and other vegetable crops, fruit and berry and ornamental plantings. It can be applied to most crops in various ways. It is best to apply potassium in the fall for autumn plowing. When implementing intensive technologies, local application during sowing and fertilizing in small doses gives the best effect.
It is recommended for application to most cereals, oilseeds, sugar and fiber crops with a high demand for potassium and low sensitivity to chlorine, as well as for annual fertilization of soils to maintain the potassium content at an optimal level.
Potassium is most effective on potassium-poor sod-podzolic soils with a light particle size distribution and peat soils. On chernozem, potassium is used primarily for crops that absorb a lot of potassium and sodium, such as sunflower, sugar beet, potatoes, root crops, vegetables, etc. On chestnut and gray soils, potassium is used depending on the crop, cultivation technology and potassium content in the soil.
Potassium can be applied to potassium-sensitive crops in the fall to allow chlorine to leach into deeper soil layers.
It is best to apply all fertilizers containing chlorine to the soil long before sowing, in the fall, before digging. Chlorine is washed out by precipitation, while potassium is well absorbed by the soil. On soils with sufficient moisture, potash fertilizers can also be applied in early spring for tillage and as fertilizer.
