Potassium fertilizer and the effect: fertilizer

Potassium fertilizers and the effect of potassium require plants for the most part during the development of new leaves, ie after dormancy in the growth phase. The element potassium is important for resistant and healthy cell tissue of plants. In addition, it helps the plant to more resistance to cold and drought. Young plants usually have more potassium in them than older plants.
Especially useful plants in the garden, such as potatoes, have a high potassium requirement, which can usually only be met by fertilizers. If you want to get high yields, you should make sure your plants have enough potassium. Potassium is essential for the production of fruits. And of course also for the protection against diseases, frost and heat.
It is necessary to fertilize with potassium fertilizers because the potassium silicates that occur naturally in the soil can hardly be absorbed by the plants. This is similar to the phosphates. Potassium is needed so that the plants can absorb enough water. Since water has an essential meaning for plants, potassium belongs to the main nutrients of the plants, as by the way also with the other organisms. A lack of potassium makes plants susceptible to disease. They look tired and the leaves turn yellow. However, these symptoms only appear after a normal growth and normal training and coloring of the leaves.
After that, yellowing usually occurs first on the lower leaves. It does not matter if it's young or old leaves. All can be infested. In order to remedy the potassium deficiency, foliar fertilization can also be carried out with potassium fertilizer. The underside of the leaves is treated with the fertilizer in liquid form. When using potassium fertilizer, it is best stored in humus soil. In sandy and calcareous soils there is often a lack of potassium. Here, the supply of potassium fertilizer is more often carried out. Potassium deficiency is often associated with calcium deficiency. Calcium deficiency is usually not detectable as a deficiency.

Ingredients and preparation of potassium fertilizers

This type of fertilizer can be produced in two ways. A first possibility arises from the degradation of kainite. A second possibility, however, arises through industrial production. This produces potassium sulfate and also Kalimagnesia. The effect of the fertilizer is mainly generated by its composition. The single nutrient fertilizer consists of kainite and its salts. However, 30 to 50 percent potassium is always present. In contrast, potassium sulphate is contained in so-called complex fertilizers. In turn, potassium and sulfur can be found in it. Furthermore, Kalimagnesia is an integral part of this fertilizer. It combines potassium, sulfur and magnesium.

Apply potassium fertilizer

Potassium fertilizer is very professional to use. For this purpose, the soil should have been previously analyzed. Many soils in gardens are already fertilized so much that they have abundant potassium. An excessively high supply should be avoided as far as possible. As a rule, the potassium denger is used as an autumn fertilizer. If it is to be used for a lawn, it should definitely be dosed high. The autumn as fertilizer is therefore recommended, as it also increases the winter hardiness of turf grasses. In particular, if the garden consists of perennials and woody plants, appropriate care should be taken. Another advantage of fertilizing with potassium is the higher tolerance of plants during periods of drought.
Potassium is very special because of its high storage capacity. Even in the rain, potassium is only very easily washed off and thus remains in the soil for a very long time. One to two years can thus be expected with an adequate supply. As an alternative, wood ash is recommended because it contains a lot of potassium. Unfortunately, fertilizing with wood ash is very problematic. Since it contains a lot of lime and also a high proportion of heavy metals, the application is often very difficult.

Effect of potassium fertilizer

Potassium is a substance that is needed by plants especially in the formation of leaves. The right time for this is the period after hibernation to growth. Potassium causes the cell walls of plants to be more resistant and also very healthy. This strengthens the cell tissue very much. This resilience is then also in the area of ​​defense against cold and dry times. Very young plants usually have more potassium than old plants.
A distinction must also be made between the plants that are to be treated with the potassium fertilizer. These include, for example, potatoes that require a lot of potassium. In general, this high demand can be particularly related to crops. Only by appropriate fertilization Gartner can cover this need appropriately.Especially who cultivates commercial crops, should therefore not do without the potassium fertilizer. The necessary mirror should therefore be strictly adhered to. This is especially for the development of fruits. At the same time arises in protection against pests, diseases and frost.

Cause of potassium fertilization

The need to fertilize with potassium fertilizer is also due in particular to the poor absorption capacity of potassium silicates. Nevertheless, it is absolutely necessary for the plants to absorb water. Therefore, potassium is one of the main nutrients of plants and is therefore indispensable. Experts speak of an essential nutrient. From these facts also consequences result with a lack of the element potassium. So a plant that suffers from a potassium deficiency, also much more susceptible to diseases. The plants quickly let the leaves hang and even yellowing. These changes are particularly noticeable when the leaves are already fully formed and the classic color of the leaves has also entered.
The decay begins at the lower edges of the leaves. The yellowing runs from the bottom up. This can affect both young shoots as well as mature leaves. The infestation can affect all leaves and here also provides the potassium fertilizer a help. Because in such cases, there is a need for foliar application. For this purpose, the potassium fertilizer is needed in liquid form. The leaves are rubbed accordingly from the bottom.

Potassium grass fertilizer


The other use of potassium fertilizer consists in storage in humus soil. Straight soils of sand or lime can therefore suffer from a lack of potassium. In such cases fertilizing is very good at frequent intervals. The potassium fertilizer should therefore always be in larger quantities in stock. In addition, there is often a shortage of calcium at the same time. However, this can not be determined by the gardener.

Effects of potassium fertilization

Potassium fertilizer is primarily used to regulate a plant, more precisely to regulate potassium balance. In the process, the well-being of the plant is brought to the foreground and the resistance of the plant is increased. Pests and diseases have no chance. Particular attention should be paid to fruit trees and vegetable beds. They have a very high demand, since they are to train fruits in the spring after the winter period. Indoor plants must be exempted from fertilization with potassium fertilizer. The application should only be used on plants in the garden. Only then can a healthy plant survive in the garden.

Worth knowing about the potassium fertilizer shortly

Potassium as an element is usually sufficiently present in the soil, but in the form of potassium silicates. Thus, the plants have difficulty in recording, similar to phosphate. Potassium needs plants for their general well-being and resilience. It allows the cells of the plant to absorb more water. A lack of potassium makes plants susceptible to disease. They look tired and the leaves turn yellow. However, these symptoms only appear after a normal growth and normal training and coloring of the leaves.
  • Plants have usually already stored potassium, but with increasing age these resources are depleted.
  • Young plants have more potassium than older plants.
  • If you use a fertilizer, you should first and foremost make sure that potassium has the highest content.
  • If all other nutrients are sufficiently available, a pure potassium fertilizer is recommended.
Especially after hibernation plants need potassium and phosphate, while nitrogen is hardly used. That's why it's the right time to use a potassium fertilizer.
  • Lawn needs potassium. This is why herbaceous fertilizers are often referred to as potassium fertilizers.
  • Especially crops need a lot of potassium. The demand can usually only be covered by fertilizer.
  • In agriculture, fertilization with special potassium fertilizer is commonplace, especially with potatoes and rape.
  • Even in forestry, potassium fertilizers are often used because potassium is needed to build wood.
  • From this one can also draw the conclusion that potassium is also needed by fruit trees and shrubs in the home garden.
  • Houseplants with woody proportions also need potassium for their health.
  • Especially for lovers of bonsai, potassium fertilizer is often indispensable, so they have years of enjoyment of their plants.
Nevertheless, every plant needs potassium and you should pay attention to an adequate supply. Important for the supply of potassium is the soil condition. Humus soils are good at absorbing potassium, whereas acidic soils often suffer from potassium deficiency, so fertilizing is usually essential.
