Kalimag, potassium-magnesium fertilizer (28%K2O/5MgO/25Ca/8Na) Kalimag (TM), Zhytomyr region.

Content of chemical elements of potash is: K — 25.3–27.4%, Mg — 5.4–9.36%, CaO — 26.85–24.05%, Na — 8.6–9.2%, and also contains sulfur, copper, manganese, zinc. Thus, during the application of potash-dolomite and potash-defect at the rate of 3 c/ha in physical water comes: K — 80–72, Mg — 16–13 kg/ha. This completely provides the plants with nutrients, and also partially neutralizes the pH and Ng. К60–80;пшениця — К60–80; кукурудза on grain=K60–80; vegetable crops — К60–80. — К60–80; соя — К40–60; овочеві культури — К60–80.

Conducted studies indicate that the use of potash for sugar beets increases their yield by 5.0–6.0 t/ha, and the sugar content of root crops — 0.6–0.9%, winter wheat — 0.5–1.0 t/ha. The winter hardiness of winter wheat increases, damage by cercosporosis, root rot, sugar beet root rot decreases, soil acidity decreases, and its nitrification improves.

As a complex fertilizer, Kalimag should be applied after disc peeling of the stubble followed by loosening with a plow, which has a positive effect on the transition of potassium, calcium and magnesium into the soil solution and the availability of nutrients to plants.

By applying potash under frost, nutrients are concentrated in the spring-summer period in a layer of 10–20 cm. This makes it possible to better use them by plants due to increased soil moisture compared to the layer of 0–10 cm.

If it is impossible to use Kalimag in the autumn period, it can be applied in post-winter tillage in the spring under deep cultivation of the soil. It is necessary to understand that by applying Kalimag, plants satisfy their need for potassium. It has a positive effect on the composition of cell sap of leaves. The resistance of plants to drought, low temperatures, fungal and bacterial diseases affects the transpiration coefficient, makes it possible to use water more economically, enhances the transfer of sugars from the leaves to the root, and affects the development of the root system. The presence of potassium increases the synthesis of sugars in plants, which increases the sugar content by 0.5–0.7%. Deficiency of potassium in the mineral nutrition system reduces the turgor of the leaves, they become light green, and the edges turn brown.

Calcium deficiency decreases with the use of potassium mag. With the use of kalimag at a rate of 5.5 t/ha, sugar beet plants satisfy their need for Ca.

Potassium promotes the process of photosynthesis and energy exchange. With a deficiency of Ca in sugar beets, plants are affected by rootworm, the yield decreases by 4–5 t/ha, and the sugar content is 0.5–0.9%. Sodium promotes the absorption of potassium. Sodium increases the amount of dry matter, both in beets and sugar beet roots. Sugariness increases under the influence of sodium.

Magnesium is a necessary nutrient for plants, just like phosphorus. It affects the course of photosynthesis, respiration, and glycolysis. Activates the enzymatic activity of plants, and also affects the transfer and assimilation of phosphorus. With magnesium deficiency in sugar beets, yellowing of the leaves is observed.

Brimstone In modern conditions, in connection with the cultivation of cruciferous crops, such as rapeseed, there is an acute shortage of sulfur. During the application of potash, plants are able to satisfy their need for sulfur. It takes an active part in metabolism, in the formation of ionic balance in cells, is part of proteins and is a key element for the photosynthesis of amino acids. Contributes to the better development of leaves and stems in plants, more uniform coloring of leaves, as well as the increase in the sugar content of sugar beets. Sulfur, which is applied with potash, helps reduce its deficiency. The complex of microelements that enter the soil together with potassium (zinc, copper, manganese) contribute to the improvement of enzymatic processes in plants, the increase in the sugar content of root crops, and the increase of immunity in plants against diseases.
