The functions of fertilizers

Over there it has always been said that “we are what we eat”and it is not only valid for us and our food, but it also makes a lot of sense when it comes to plants, since plants could not live if they did not receive the nutrients they need for it.

The soil in which the plants are is the one that is responsible for providing the necessary nutrients, and this in turn receives them from the fertilizers. Thus, fertilizers are very important for the correct development of any tree or plant, so take note of the functions of fertilizers that we explain in this Green Ecology article.

types of fertilizers

Here we explain what types of fertilizers there are and how they are applied:

  • soluble fertilizers: they are prepared so that they can be mixed with water and applied to the plants, either with a hose or with a sprayer. It is the most suitable type of fertilizer for plants that need foliar feeding and can also be applied directly to the roots.
  • mixed fertilizers: If you use one of these and apply it directly to the leaves, the plants are able to absorb those nutrients immediately and begin to grow as the leaves absorb them and go directly to the growing area for development.
  • granular fertilizers: These are applied directly to the soil and that is where you should mix it to avoid burning the roots of the plant, especially those that are still in the growth phase. This type of fertilizer is usually applied before sowing or during the vegetative period since contact with the leaves causes damage to the plants.

What are the functions of fertilizers

Any of the fertilizers you use will have three main elements: nitrogen, phosphorus and potassium, and in order to choose the right composition you have to know what effect will each of them have in your plants, since it is not the same for all.

In summary:

  • nitrogen: This works by promoting green leaves and a lack of this element can cause plants to have a yellowish color and leaves to look old and worn.
  • The match: This promotes the proliferation of healthy cells and it is good that you apply a fertilizer high in phosphorus just before flowering.
  • potassium: this is vital as it helps keep the roots healthy, so without it growth is much slower and weaker.
