Kalimagnesia (kalimag) is a soluble mineral fertilizer with several nutrient components. It is made from natural minerals. Kalimagnesia and kalimag are different substances, but the differences between them are insignificant; they are irrelevant to the cultivator. The drug is produced by various companies; in retail, the most common packages are 1 kg and 3 kg. Instructions for using this fertilizer are presented below.

Composition and purpose

Outwardly, the mass looks like a powder or granules (or their mixture) of a gray or grayish brick shade. Contains two basic components - potassium sulfate and magnesium sulfate. These substances, dissolving well in water or moist soil, become sources of available potassium, magnesium and sulfur. Sometimes there is an admixture of a small amount of chlorine - but not more than 1%, which allows us to consider this fertilizer chlorine-free.

Kalimag is used for dry application into the ground, as well as for liquid root and foliar dressing. The beneficial effect of the drug is most fully manifested in the growth phase of tubers and root crops, ripening of fruits.

The effect is especially noticeable on lands such as:

  • light sandy and sandy loam (feed is needed multiple, stage-by-stage);
  • raw peat;
  • sod-podzolic (especially sour, light and medium texture);
  • poor loam.

Fertile chernozems and gray soils, as a rule, do not need the introduction of kalimag.

Mechanism of action

Potassium magnesia is especially valuable because its components complement each other.

Potassium

  • responsible for the absorption of water;
  • relieves temperature stress;
  • forms tubers and ovaries;
  • improves taste, color, crop safety;
  • increases winter hardiness.

With potassium starvation, plants become lethargic, the growth of ovaries and tubers is inhibited. The foliage (especially the lower one) turns yellow or brown between the veins, becomes covered with dark spots. Cucumber fruits become thinner at the base (take the shape of a pear).

Magnesium

  • is a part of chlorophyll, regulates photosynthesis;
  • helps to absorb phosphorus;
  • in fruits and tubers increases the amount of carbohydrates (sugars, starch), vitamin C.

Deficiency of this element leads to the destruction of chlorophyll. The veins of the leaves remain bright green, but the rest of the leaf area turns yellow or orange, then turns red or brown. The lower leaves break off, the overall development is delayed. Fruits do not accumulate sweets, and tubers do not accumulate starch.

Sulfur

  • helps to synthesize chlorophyll;
  • develops a root system (especially in plants of the legume family);
  • is a part of tissues and vegetable oils (in cultures of the Cruciferous family, as well as in onions and garlic).

The lack of sulfur is manifested in the blanching and shrinking of the leaf plates, inhibition of root growth.

Root and foliar feeding with potassium-magnesium fertilizer prevents nutritional deterioration, especially on light soils and sensitive crops.

Plants responsive to the introduction of potassium magnesium

The fertilizer is especially rich in potassium and is ideal for those crops that need it (and yet do not tolerate chlorine). A substantial amount of magnesium and assimilable sulfur make kalimag attractive to many plants.

Top dressing will be delighted:

  • grapes;
  • potatoes;
  • cucumbers; zucchini; melons and gourds;
  • tomatoes, peppers, eggplants;
  • beans, beans, peas;
  • sunflower;
  • sugar beet;
  • cabbage, radish, daikon, radish, turnip, rutabaga, turnip;
  • onions, garlic;
  • carrots, beets, celery root;
  • strawberries, raspberries, black currants, cherries, apple trees;
  • conifers;
  • roses;
  • decorative crops with an abundance of foliage;
  • pasture grasses;
  • buckwheat.

The yield increase can be 30-40%. The nutritional value of the crop increases significantly, the taste is noticeably improved. The winter hardiness of fruit and berry and ornamental crops increases, the setting of flower buds is improved.

Advantages and disadvantages

Like many other fertilizers, Kalimag requires strict adherence to dosages. We must not forget that this is a chemical.

Minuses:

  1. In comparison with potassium sulfate and potassium chloride, it contains less mass fraction of potassium.
  2. Compared to Magnesium Sulphate, it contains less magnesium and sulfur.
  3. Ineffective on chernozems and gray soils (magnesium sulfate is more useful here).
  4. It is impossible apply on salt licks (increases salinity).
  5. Washes out quickly on light and damp lands.
  6. Toxic for plants with excessive application (darkening and shallowness of foliage).

Pros:

  1. Contains a 3-component complex of substances, complementing each other's action - this is the advantage over simpler ones: potassium chloride and sulphate, magnesium sulphate, dolomite flour, potassium-lime mixture.
  2. No toxic for many chlorine plants (as opposed to Potassium Chloride).
  3. Okay dissolves.
  4. Does not cake during storage.
  5. Suitable for different types of dressings, in any month of the season.
  6. Fast and complete assimilated by plants.
  7. Good for many cultures.

This fertilizer complex has no significant drawbacks. If the recommendations are followed, it shows high efficiency.

General rules for feeding with Kalimag

Fertilizer is useful in the garden and vegetable garden throughout the season.

  1. Autumn or spring pours under plowing, digging: 3-4 kg per one hundred square meters.
  2. Applied dry (and loosens) in the spring in the root zone of trees and bushes: 35 g per 1 sq. meter. At the end of August - a similar procedure for strawberries and conifers.
  3. For fruit and berry crops: spraying during the growth of ovaries (20 g per 10 l of water).
  4. Potatoes (for starchiness and keeping quality): 1 teaspoon per hole when landing. Before hilling, sprinkle 200 g per 10 sq. meters; or sprinkle during the budding period, water at the beginning of the growth of tubers (20 g per 10 l of water).
  5. Watering or spraying root vegetables, onions, garlic - in the initial stage of thickening of the underground part: 25 g per bucket of water.
  6. Tomatoes, cucumbers, other vegetables: 2-3 root and foliar dressings during the growing season (20 g per bucket of water).
  7. Ornamental plants: spraying before flowering and watering in late summer: 25 g per bucket of water.

Equal volumes of water and kalimag weigh the same: a teaspoon - 5 g, a tablespoon - 15 g, a glass - 200 g.

Instructions for use for grapes

For grapes, the sugar content of the berries is especially important. Kalimag is one of the most effective means for sugar accumulation. With a lack of food, the bunches dry out. In addition, this fertilizer increases the winter hardiness of the grape bush.

  1. In July or August (at the time of an active increase in the size of the ovary), a liquid root feeding is given: 1 tbsp. spoon for 10 liters. water - 1 bush. A solution of the same concentration can also be used for 2-3 sprays.
  2. In autumn 20 g is introduced into the root zone of each bush (loosen dry and water).

Mixing rules

It is not recommended to combine Kalimag with urea, stimulants and pesticides.

First aid for poisoning

Belonging to the III class of danger indicates that the substance can become dangerous only if used for other purposes. May cause toxicity if swallowed. In this case, vomiting cannot be induced; you need to drink 2-3 glasses of water with crushed tablets of activated carbon (10-15 pieces), seek medical help.

Shelf life and storage conditions

The guaranteed storage period is 5 years after production. However, the chemical is stable and has no real shelf life.

The drug does not have special requirements for storage conditions: it does not burn, does not explode, does not compress, does not absorb moisture from the air. It should only be protected from water: it dissolves easily.

Kalimagnesia is an affordable, easy-to-use yield-enhancing agent. This is one of the best drugs that improve the presentation and nutritional value of the crop.


General description and chemical composition

Potassium-magnesium fertilizer of this group is used to enrich depleted soil types, for chlorophobic varieties. Consists of three components:

  • magnesium (9% of the total mass)
  • potassium salts (28% potassium oxide)
  • blotches of sulfur.

Suitable for various soil types:

  • loams with low content of magnesium and potassium
  • peatlands with magnesium but no potassium and sulfur
  • depleted soils with acid composition
  • sandstones and sandy loam soils, where, due to increased aeration, nutrients are washed out of the ground during the growth and fruiting phase.

Kalimag is not recommended to be added to chernozem soils. They do not require any supplements based on magnesium and potassium, so the approval will not increase the yield.

However, some crops, even those growing on black soil, consume large amounts of potassium from the soil during the growing season:

  • sunflower
  • cucumbers
  • potatoes
  • beet.

In such cases, feeding is used in small portions, taking into account whether there is a deficiency of sulfur and magnesium in the soil. It is not used on saline soils - there is no potassium deficiency, its content is extremely high. If potassium magnesium is added, they become unusable.

Potassium sulfate is also used to increase the yield of such crops:

  • bell pepper
  • soybeans, beans
  • berry bushes
  • tobacco
  • indoor flowers
  • grapes
  • cabbage
  • buckwheat
  • carrot
  • lemons, oranges.

In addition to basic substances, the composition may contain traces of chlorine - up to 3%. However, the insignificant content allows this top dressing to be classified as chlorine-free.

The powder is well stored, does not cake. There are few impurities in the solution, all components are quickly distributed in water.

Impact on cultivated plants

This top dressing is especially good in that all substances in the composition are mutually complementary:

  1. Potassium responsible for ovaries and tubers, water assimilation, increases marketable and taste parameters, increases the keeping quality of the crop, as well as winter hardiness of the crop. If a deficit occurs, the plant looks sluggish, the growth of ovaries and the enlargement of tubers are significantly reduced. The lower part of the foliage can turn yellow along the veins, covered with brown spots. Cucumbers deform and become pear-like (thinner at the base).
  2. Magnesium regulates the synthesis of chlorophyll, participates in the assimilation of phosphorus. Saturates tubers and fruits with sugars, vitamin C and starch, making them more nutritious. With a deficiency of magnesium, chlorophyll is destroyed, as a result of which the leaves turn yellow at the edges, over time they acquire a red or brown tint. The lower part of the foliage falls off, the growth of the culture is slowed down. There is little sweetness in the fruits, and starch in the tubers.
  3. Sulfur also participates in the synthesis of chlorophyll, the growth of roots, especially legumes, is a part of many tissues. With a deficiency, the leaf plates become small, pale, the development of the root system is delayed.

Kalimagnesia is used for various cultivated plants in order to increase their yield, but fertilizer acts on certain crops in different ways:

  1. Kalimagnesia for cucumbers... Top dressing enhances the movement of juices, increases the intensity of growth, fruiting.
  2. Application for tomatoes... When this top dressing is applied, the fruits become brightly colored, acquire the correct shape. With a deficiency of potassium in the soil, tomatoes do not ripen, light streaks become visible on the leaves. You can add the composition directly to the fruiting phase.
  3. Top dressing for roses enhances the degree of winter hardiness of flowers. Kalimagnesia makes it easier for roses to endure the winter, enhances sap flow and distribution of nitrogen and phosphorus in all parts of the plant. Potassium gives the buds a bright color.
  4. Grapes this fertilizer makes it more frost-resistant, improves the transportability of the crop, as a result of which it retains its external presentation for a longer time, and also protects against diseases that can be caused by a deficiency of minerals. Sulfur and magnesium enhance the sugar content and juiciness of the fruit.

Also, on many crops, Kalimag acts as a stimulant of immunity, increases protective barriers against diseases and pests.

Benefits of using

In comparison with other means for root and foliar dressing, potassium magnesium has a number of advantages:

  • contains three components at once that complement each other
  • due to the low level of chlorine, it does not have a toxic effect
  • even during long-term storage does not cake
  • easily dissolves in water when preparing a working solution
  • suitable for application directly to the soil during irrigation and for spraying
  • can be used in any month both at the stage of ovary emergence and during fruiting
  • assimilated by all cultures in full
  • suitable for flowers, shrubs, vegetables.

Top dressing has no significant drawbacks. However, it is not used on chernozems, as well as on salt licks, it is washed out quickly enough in damp soils with good drainage, if the dosage is not observed, it can have a toxic effect on the plant.


Fertilizer Kalimagnesia

Suitable for:

Potassium magnesium can be introduced into the soil during digging or processing of plants. It is not recommended to deeply deepen the granules of the nutrient composition, as this reduces the accessibility of the root system.

Application rates

  • when applying the main dressing in spring or autumn, 30-40 g or 5 liters of solution per 1 m² are required
  • for the nutrition of fruit trees and shrubs, 20 - 30 g of substances are introduced per 1 m² of the trunk circle
  • vegetable crops are fed according to the formula 15 - 20 g per 1 m²
  • for root crops and flower crops, 20 - 25 g of nutrients per 1 m² are required.

How to deposit?

  • root top dressing is carried out with dry Kalimagnesia "Buisk fertilizers" or a solution prepared in a ratio of 20 g per 10 l of water
  • foliar dressing, produced in the form of spraying, is also carried out with a solution, which is formed by dissolving 20 g of granules in 10 liters of water.

Periodicity

  • the main application for tomatoes, cucumbers and other vegetable and fruit crops is carried out 1 time in spring or autumn
  • additional application for roses, flower and vegetable crops is carried out 2 times with an interval of 2 weeks.


Kalimagnesia is available in the form of gray or pink granules. The composition of the Kalimagnesia fertilizer "allows you to feed vegetable and flower crops, fruit trees, houseplants. It is especially important to use food with a lack of potassium.

Fertilizing pros and cons

  • the granules dissolve quickly in water
  • helps to increase yields
  • increases the keeping quality of plants
  • suitable for greenhouses and open ground
  • safe
  • differs in low cost and availability.

  • Not recommended for use in chernozem soils. With an excess of nutrients, it can lead to the death of plants.


Action of the main components

The value of Kalimagnesia lies in the balance of the composition in terms of the content of all the necessary minerals.

So, potassium provides:

  • excellent water absorption
  • helps relieve stress due to temperature changes
  • formation of healthy tubers and ovaries
  • improving the taste and color of the crop
  • increased resistance to low temperatures.

With a deficiency of potassium, the development of the plant slows down, the branches become weak and lethargic. The foliage begins to turn yellow or brown. Brown spots are formed on the leaf plates. Deformation of fruits occurs in some crops.

The introduction of magnesium into the soil contributes to:

  • regulation of photosynthesis
  • helps to better and more absorb phosphorus
  • the content of carbohydrates, ascorbic acid in fruits and tubers increases.

With a lack of magnesium, chlorophyll is destroyed. The leaves change their color from green to orange, yellow, brown. The lower leaves fall off. A slowdown in plant growth and development is observed. There is no accumulation of sugars in the fruits, which distorts the taste. There is a lack of starch in potato tubers.

The presence of sulfur has the following effects on plants:

  • supports the chlorophyll formation process
  • develops the root system
  • is a constituent element of fabrics and oils of vegetable origin.

When plants lack sulfur, the leaf plates turn pale and become smaller in size. The root system begins to develop much more slowly.

In general, the introduction of Kalimagnesia compensates for this deficiency and stops the deterioration of the nutritional process. Top dressing is especially effective for light and sensitive soil. As a result, the general health of the plants increases, the stems and branches become stronger, the root system begins to fully develop. Plants look healthy and robust, and fruitful crops yield good yields.


How to apply?

The use of potassium magnesium for the garden has its own specificity, depending on the amount and variety of nutrients already present in the soil.... On average, the dose of application of the drug reaches from 100-150 to 300-350 kilograms per hectare.

If Kalimag is used as root feeding, then it will take about 10 grams per square meter, and for the main application it is necessary to increase the dosage to 40 grams per square meter. To replenish the content of potassium and magnesium in soil in spring, for light soils, 10 grams per square meter is used, and in autumn on clay soils, somewhere around 20 grams per square meter is used. In this case, it is more convenient to apply fertilizers during digging or plowing. When applying drugs to the furrows, the amount is reduced by 2 times, and in greenhouses and greenhouses, the dose is reduced to 5 grams per square meter.

Fertilization during the growing season occurs according to instructions that are individual for different crops.

For grapes regular feeding with potassium magnesium is very important, since the fruits become sweeter, the bunches themselves dry less, and the shrub copes with the winter much more successfully. While the fruits are ripening, the bushes are watered with Kalimaga solution, and there is one bucket for each bush. To prepare the liquid, a tablespoon of the drug should be diluted in 10 liters of water. After 2-3 weeks, several foliar treatments can be carried out for grapes using the same solution. In addition, in the autumn, it is recommended to add 20 grams of potassium magnesium to the root circle, and then slightly loosen and moisten the soil. This action will provide the culture with a better wintering period.

To feed tomatoes during spring digging, it is necessary for every 10 square meters, add from 100 to 150 grams. Further, during the growing season, the shrub can be alternately sprayed and watered with a solution of potassium-magnesium fertilizer, for which 20 grams of the mixture will need to be diluted in 10 liters of clean water. As a rule, from 4 to 6 such treatments are carried out per season. Regular use of potassium magnesium should increase the number of tomato fruits by almost one and a half times.

If fertilizer is purchased for roses, then you will need to carry out 2 types of processing: foliar before flowering and regular watering at the end of the season. To prepare the solution, you need to dilute 25 grams of the drug in a liter of water.

When growing cucumbers "Potassium Mag" is used during pre-sowing procedures, and it is better to use the drug either before rain or before watering. This culture requires 100 grams of substance per square meter. A couple of weeks after direct planting, 200 grams of the drug are applied to 100 square meters, and after another 15 days - 400 grams to the same area.

Additionally, it is recommended to enrich the beds with organic fertilizers, for example, bird droppings and mullein.

As for potatoes, this crop requires several applications of potassium magnesium per season. First, even before planting, a teaspoon of the substance is laid in each hole. Further, before hilling, each square meter must be enriched with 20 grams of the drug. Finally, when the tubers have already begun to actively form, it will be necessary to add the same 20 grams of the mixture, diluted in 10 liters of water. If necessary, another foliar procedure can be arranged when the buds begin to form.

When growing cabbage potassium-magnesium fertilizer is laid during loosening into pre-moistened soil. For each instance, you will need to use 10 grams of substances.

Carrot requires the introduction of 30 grams of the drug per square meter. It is best to process in the spring to ensure the sweetness of the roots and increased fruiting.

When planting beets each square meter of planting is enriched with 30 grams of potassium magnesium. In addition, when the underground part begins to thicken, root treatment can be carried out by preparing a solution of 25 grams of the drug and 10 liters of liquid. The same processing will be required for onions and garlic.

When growing raspberries fertilizer will need to be applied when the crop begins to bear fruit. Culture requires the use of 15 grams of the drug per square meter.

Fertilizer is best embedded around the perimeter of the bush in pre-irrigated soil, deepening the granules by 20 centimeters.

Decorative conifers fertilized with "Kalimag" in autumn and spring. For each square meter, it is customary to make 35 grams of the drug, and departing from the trunk by 40-50 centimeters.


Conclusions about Kalimagnesia

  • Potassium magnesium as a fertilizer has the ability to increase the sugar content in crops.
  • Thanks to its use, the amount of starch in potatoes increases.
  • Plants, when using the product, acquire immunity to disease and frost.
  • But gardeners should remember the rules for using and storing the drug.

Many gardeners believe that potatoes can grow well without additional nutrient input.

Probably the most useful gift of nature for summer residents is black soil, the scientific name of which is.

Urea is a drug that is quickly absorbed by plants, especially in warm weather. Foliar.

Elements such as nitrogen, phosphorus and potassium are essential for growing healthy and strong garden plants.
