Potassium chloride is an effective mineral fertilizer. It is permissible to use it alone or combine it with nitrogen or phosphorus fertilizers. The composition is suitable for garden and ornamental plants. Regular use of potassium chloride helps to strengthen crops, increase resistance to temperature fluctuations, form a dense crown and get larger fruits.

Description and physicochemical characteristics of potassium chloride

Potassium chloride is produced in the form of a friable mass of white or pinkish hue or in the form of granules. The fertilizer contains 60% of the active component - potassium oxide. The product mixes easily with water.

The substance is considered the main potassium drug. It is allowed to use it in its pure form. However, there are also combined compositions with copper, bromine and other components.

Signs of deficiency or excess

Lack of potassium in the soil affects the general condition of the plants. Under natural conditions, it is present in the soil only in combination with other components. Potassium deficiency in various types of crops is accompanied by the following manifestations:

  • marginal burn - in this case, a light border appears along the edges of the foliage, which subsequently dries up;
  • compaction of greenery and a change in its color;
  • the formation of brown spots;
  • weakening of the main stem and shoots;
  • lagging behind in comparison with the average parameters;
  • late flowering or complete absence of buds;
  • the tendency of the culture to damage by fungi.

At the same time, potassium chloride often provokes overfeeding of weakened plants. In perennial crops, it manifests itself in the defeat of the roots and freezing of the buds in winter. In annuals, the violation is noticeable immediately. In this case, the stems lie down and begin to rot near the roots.

To save at least part of the crop, it is worth stopping all feeding and reducing watering. You should also remove some of the shoots with unripe fruits.

How to apply and application rates correctly

Not every culture requires potassium chloride. Therefore, when using a substance, it is important to be guided by the instructions.

Potatoes

The beds for plants need to be fed with the composition 1 time. This is done in the fall. Thanks to this, the volume of the substance is normalized by the spring. On loamy or clayey soil, use 100 grams of substance per 1 square meter. It is worth adding cement dust and flour to light types of soil.

Tomatoes

Tomatoes do not like chlorine, so you need to apply fertilizer in the fall, under a shovel. Use 100 grams of the product per 1 square meter.

Cucumbers

With a lack of potassium, cucumbers lose their taste and volume. A test must be carried out before fertilizing. To do this, pour 500 milliliters of solution under 1 lash. After a few days, the reaction can be assessed. If the plant begins to actively develop, you can feed the entire garden.

During the season, cucumbers are fed in greenhouses 2-3 times. When grown outdoors, fertilization is required 5 times.

Grapes

This shrub should not be fed with potassium chloride, since it does not tolerate chlorine. However, grapes need potassium supplements. They help to increase frost resistance, improve fruit ripening and vine development. However, for grapes it is better to use potassium sulfate.

Fruit trees

All plants in this category require feeding. Fruit trees take chlorine well. Under each fruiting trunk, 150 grams of potassium chloride must be added. If the trees grow in black soil, 120 grams of fertilizer will be enough. When growing crops in light soil, the dosage is increased to 180 grams.

Flowers

Feeding is worth taking into account the variety of plants. This should be done several times during the season. At the same time, for 10 liters of water, you need to take 20 grams of funds for large-bulb crops. Small-bulbous plants require no more than 10 grams of feeding. For roses, make a solution of 20 grams of the drug.

Fertilizer compatibility

The drug can be combined with lime, chalk, dolomite flour. It can be combined with ammophos, ammonium sulfate, diammophos. It is also permissible to use combinations with chicken manure or manure.

Right before use, the composition is allowed to be combined with ammonium, sodium or calcium nitrate. Combinations with urea and superphosphate are also possible.

Safety engineering

The substance can be classified as moderately hazardous. It does not affect the integrity of the skin, but prevents the regeneration of damaged areas. Also, the composition can provoke irritation and lead to inflammation. Therefore, when working with this fertilizer, you need to use protective equipment that cover the damaged areas of the skin.

When combined with air, the composition does not provoke toxic compounds that pose a danger to the body. The substance is non-flammable and non-corrosive.

Storage conditions and shelf life

The drug is distinguished by high parameters of hygroscopicity. Therefore, it should be kept indoors with a low level of humidity. It is important to ensure that the composition is not affected by precipitation or groundwater. On the street, top dressing is required to be kept in an airtight container or plastic bags. This must be done under a canopy.

The duration of storage of potassium chloride does not exceed six months. After the specified time has elapsed, the dressing loses its external characteristics and forms lumps. However, its chemical properties are fully preserved.

Potassium chloride is considered an effective fertilizer that helps improve the growth and development of crops. In this case, it is important to strictly adhere to the instructions for using the substance. This will help to achieve the desired results and not harm the plants.
