NPK

What is NPK and its importance for plants

The abbreviation NPK stands for: N – nitrogen, P – phosphorus, K – potassium. These elements are very important for plant nutrition and development.

Nitrogen(N) – is a component of all amino acids, proteins, and vitamins. It is a building block of plant cells. Stimulates the development of stems and leaves of plants, is the main element of increasing the productivity of vegetable crops. An insufficient amount of this element is manifested in a decrease in the growth of the aerial parts of plants, the leaves turn pale or acquire a pale green-yellowish color. An excess of nitrogen leads to overgrowth of the leaf apparatus to the detriment of the fruit, accumulation of nitrates, reduced quality and keeping quality of vegetables, and stimulates the development of diseases.

Phosphorus (P) – promotes the development of the root system (lengthens root hairs and increases their number), which accelerates seed germination and seedling survival. This directly affects the increase in yield and the formation of high-quality fruits. With a lack of phosphorus nutrition, flowering and ripening processes slow down, and plant growth slows down. With an excess of phosphorus, very early ripening of fruits can be observed, which often leads to damage by diseases and pests.

Potassium (K) – is not a part of organic compounds, but at the same time promotes the transport of plastic substances from vegetative organs to productive ones (plastic substances strengthen fruits, reduce damage by diseases and pests, and improve storage), activates the synthesis of many vitamins and carbohydrates, and reduces the accumulation of nitrates. Lack of potassium nutrition reduces the synthesis of vitamins and carbohydrates, dramatically increases the content of nitrates, and reduces the shelf life of products. Excess potassium reduces plant metabolism and reduces the intake of other substances (calcium (Ca), magnesium (Mg), etc.).
