The role of macronutrients in plant nutrition

One can ignore the topic of fertilizers indefinitely and not deal with their role in the development of plants, but without this knowledge, the excellent results in carpentry and horticulture are inconceivable.

If you want your flowers to grow well, choose only reliable sellers. At, for example, you can buy peonies and be sure that you will enjoy them. Carefully study how to care for your plants, because in their chemical composition there is almost the entire periodic table of the elements, and there is still not enough data on the action of certain substances, but the main ways of controlling metabolic processes have been studied. The most important in root canal treatment are the following macronutrients:

  • Nitrogen;
  • Phosphorus;
  • Potassium;
  • Magnesium;
  • Calcium;
  • Sulfur;
  • Iron.


One of the most important elements for plant nutrition and the formation of chlorophyll. Participates in the regulation of the growth of the green mass and affects the duration of flowering.

With a defect:

  • The growth slows down.
  • Leaves turn yellow due to insufficient chlorophyll production: first from below, because the element mainly accumulates in young tissues, but gradually all the green mass begins to suffer.

With excess:

  • Too fast growth with the formation of loose tissue.
  • Decreased immunity to disease.
  • Flowering is delayed or does not take place at all.
  • Nitrates are formed by over-fertilization with nitrogen.


It is indispensable in most metabolic processes, participates in the formation of buds and fruit, influences the health of the root system and the winter hardiness of the plant.

With a defect:

  • Delayed flowering.
  • The ripening of fruits and seeds slows down.
  • Defective fruits and seeds are formed.
  • Leaves unnaturally darken, turn bluish or reddish-brown – the process goes from lower to younger.
  • Leaves are bent up.

With excess:

  • The development slows down.
  • Decreases resistance to lack of water.
  • The leaves turn yellow due to disturbances in the production of chlorophyll and become covered with necrotic spots, after which they fall off.
  • The plant ages quickly.


It takes part in the processes of carbohydrate, protein, hydrogen change, photosynthesis, affects the ability of the plant to store moisture, strengthens tissues and increases resistance to diseases and pests.

With a defect:

  • The leaves take on a wavy, wrinkled shape, curl downwards.
  • Burns and brown spots appear on the edges of the leaf plate.
  • The leaves become bluish, dull, with a bronze hue.
  • The stem becomes thin and loose.
  • Plant development and bud formation are slowed down.
  • Increased susceptibility to fungal diseases.

With excess:

  • The growth slows down.
  • The plant is stretched.
  • The leaves are deformed and yellow – the process goes from bottom to top.

Since a deficiency or excess of one element can impair the plant’s ability to assimilate others, it is not always easy to properly determine and correct the cause of the disease. When applying fertilizers, strictly follow the manufacturer’s instructions: it is always possible to make up for the deficiency, but the overdose can no longer be neutralized.
