What are the most common plant nutrients used for?

Our plants, just like us, need “food” to develop properly, because they do not live on water alone. And although this is very generic since water is really more for being able to assimilate nutrients than for food, there are 13 essential mineral elements What plants need to live.

plant nutrients

We will know a little above what each of the nutrients of the plant is used for, or rather what the plant needs at all times.


Plant nutrients and their functions

On the blog we have seen a multitude of organic remedies and natural fertilizers to provide our plants with the nutrients they need. Some of them provide more of a specific nutrient than others. but in general it is good to alternate between one and the other.

In addition, the fertilizers and fertilizers that we use not only help us to improve the growth of the plant and the development of its fruits, but also many solid fertilizers that we use also help us to improve the structure of the soil, providing organic matter, minerals and to improve its bacterial life, giving our plants a perfect place to grow.

What is nitrogen used for in plants?

We will differentiate between two types, the macronutrients plants, what they will need more continuously and in greater quantity, and the micronutrients plants, still as necessary but in lesser quantities and often already available in the ground, because it is not so common for them to run out.

nutrients in plants


The three basic macronutrients that plants need most continuously and abundantly are known as N, P, K:

  • Nitrogen (N): Many readers always ask us what is the use of nitrogen in plants. Well, this mineral especially helps the plant to develop its vegetable part, both the stems and the leaves. But an excess of nitrogen makes the plants weaker and also susceptible to pest attacks.
  • Phosphorus (P): It is mainly used in tubers, as it promotes their development. It also serves to neutralize excess nitrogen and stimulate seed and fruit production.
  • Potassium (K): It improves the smell of the flowers and their production, in such a way that we improve the quality of the fruits, it also activates the development of the roots to a lesser extent.

These macronutrients, although they are more necessary than micronutrients, we should not be so aware of:

  • Calcium (Ca): It provides plant resistance and helps form tissue cell walls.
  • Magnesium ( Mg ): It is essential to our plants since it is the mineral element of chlorophyll and brings color to plants.
  • Sulfur (S): It is complementary to nitrogen and stimulates plant growth.

  • Ecological water-soluble fertilizer with calcium and boron to improve firmness, fruit set and cracking problems.
  • FORCE-Ca+B ECO brings firmness and quality to fruits thanks to its excellent penetration capacity and efficient translocation of nutrients to areas of demand.
  • FORCE-Ca+B ECO is a stable formulation of calcium, boron and amino acids, whose high organic content gives it an added advantage as a plant metabolism activator.
  • Prevents and corrects calcium deficiency states; especially those in which boron is involved.
  • It constitutes a basic contribution in the phenological phases of fruiting and fruiting, so important to ensure productivity.


Providing plants with less need for these micronutrients, which are normally available in the soil and even earthworm humus ensures that there is no deficiency in these trace elements.

– Iron ( Fe ): It is a constituent of several enzymes and certain pigments; Helps reduce nitrates and sulfates.– Zinc ( Zn ): It is involved in nitrogen metabolism and in the formation of favorable pigments. It stimulates various enzymatic activities.– Manganese (Mn): It is present in various biological processes including photosynthesis, respiration and the assimilation of nitrogen by the plant. – Boron (B): Promotes good cell division, strengthens the cell wall, helps pollination and flowering.– Copper (Cu): Necessary for the process of photosynthesis, essential for the respiration of plants.– Molybdenum (Mo): Nitrate reduction catalyst, helps fix atmospheric nitrogen. – Chlorine ( Cl ): Above all, it has an activity linked to photosynthesis and the cellular maintenance of plants.

To identify the lack of nutrients, the ideal is to do it by observing the leaves that often give us the necessary clues to know what is happening to our plants, in this article I leave you a little more information about this topic :
