For your plants to grow bright, lush and fragrant, they need to be well fed. The diet of plants includes water, organic and mineral fertilizers. Fertilizers contain a large list of chemical elements that help plants grow and develop, remaining alive and attractive throughout the summer cottage

Plant nutrition elements

For normal growth and development of plants, they, like humans, require macronutrients and micronutrients.

The main macronutrients consumed by plants in large quantities are: nitrogen, iron, potassium, calcium, magnesium, phosphorus. Microelements such as boron, manganese, copper, zinc and others play an equally significant role in plant life.

The lack or excess of the listed chemical elements affects the development of plants, especially their appearance. Leaves begin to turn yellow or brown, flower buds dry up without blooming and delighting the world with their beauty.

Functions of some batteries

• Nitrogen - plays a huge role for vegetative growth, especially in the initial period of plant development.

• Bor - helps to develop young leaves and flower buds. With a lack of boron, unblown ovaries begin to fall off, so the plant gives few flowers.

• Iron - similar to the role played by iron in the human body, where it is an important element of blood, in plants iron is a part of chlorophyll and chloroplasts. Iron deficiency causes premature aging of the leaves. The chlorophyll in them begins to break down, making the leaves pale and old.

• Potassium - performs the function of a preventive doctor, increasing the plant's resistance to diseases, making them hardened, do not succumb to cold and frost. It helps the roots to be strong and strong.

• Calcium - it is applied to acidic soil to neutralize the increased acidity for plants that prefer normal soil.

• Magnesium - is necessary for plants to maintain the green color of the leaves. Since it is part of chlorophyll. With a lack of magnesium, the leaves become brittle and acquire the deadness of pale marble.

• Phosphorus - plays the role of an artist, improving the color of leaves and flowers. Promotes the formation of flower buds, helps their growth, development, making flowering abundant and bright.

Simple fertilizers

Fertilizers that can be purchased in the store are simple and complex. Simple fertilizers include nitrogen, potash and phosphorus.

• Nitrogen fertilizers - as a rule, plants are fed with nitrogen fertilizers in the first half of summer, when there is an intensive growth of plants. They are represented by the following types: urea or urea; ammonium nitrate; sodium nitrate; calcium nitrate; ammonium sulfate. When using them, it should be borne in mind that some of them acidify the soil, others alkalinize.

• Potash fertilizers - the potassium necessary for the roots is contained in fertilizers not in pure form, but in combination with other chemical elements that are poorly tolerated by plants.

For example, potassium chloride contains chlorine ion, which is harmful to plants. Therefore, it is better to bring it in in the fall, so that chlorine, along with autumn rain flows, leaves the soil, and potassium is fixed in it and helps in the development of roots in the spring.

For feeding, it is better to use

potassium sulfatewhich does not contain chlorine. But it acidifies the soil, which must also be taken into account.

A very valuable potash fertilizer that also contains magnesium -

potassium magnesium

How potash fertilizer is used

wood ash

• Phosphate fertilizers - as a rule, they are used for the autumn and spring filling of the soil during its digging. These are simple superphosphate, double superphosphate, bone meal, phosphate rock.
