Fertilize an Olive Tree: What Components Do You Need? How to do it?

The olive tree is a fruit tree that allows olive oil to be produced and is not difficult to grow, although it is important to know how to fertilize it.

Although this tree does not grow too large, it usually tolerates varied climatic conditions, with the wind being the one that can cause the most damage.

In this sense and in order to let you know how to take care of this tree, we will talk a little about its fertilizer and the correct way to use it.

Why fertilize an olive tree?

The olive tree is a tree that is not demanding with the soil, giving good results both in irrigated and dry land.

It adapts to different types of soils, however it needs a good amount of water. It is important not to forget that like all trees, stagnant water is very detrimental. Although it is considered a somewhat hardy crop.

Since this plant has a good amount of nutritional requirements, paying it becomes mandatory for your health.

This also has a great influence on the reproduction of the olive tree, since fruits of greater or lesser quality will be produced depending on the care provided.

It is important to consider that it cannot be fertilized with any type of material, since the nutrients it needs are specially defined.

That is why you must be careful and protect yourself from any deficit that may arise.

What does the olive tree need in terms of nutrients?

In general, this tree requires the presence of nitrogen, phosphorous, boron, iron and calcium.

All of them ensure that it can have an optimal and adequate development for its production.

planting density Average production per tree Unit (fert/ha) Subscriber (kg/ha)
150 trees/ha rainfed 15 to 30kg N90 – P2O5 30 – K2O 90
150 trees/ha rainfed 30 to 40kg N120 – P2O5 45 – K2O 120
  • 600kg of Ammonium Sulfate
  • 250kg of Superphosphate
  • 250kg Potassium Sulfate
200 trees/ha rainfed 40 to 50kg N180 – P2O5 80 – K2O 200
  • 900kg of Ammonium Sulfate
  • 450kg of Superphosphate
  • 400kg Potassium Sulfate


In the case of nitrogen, it is known that it allows the acceleration of vegetative activity, which promotes the correct development of the plant.

Likewise, it facilitates that it has a greater capacity to assimilate any other element, directly influencing its production.

This compound is not very stable in the soil, making it necessary to keep it in mind when fertilizing plants.

Nitrogen is a fundamental nutrient for olive cultivation due to its effect on vegetation and olive production. The olive tree usually acquires nitrogen through its absorption in the soil, either in mineral or organic form.

Nitrogen also accelerates vegetative life and plant development, increases chlorophyll, and intensifies the green color of leaves. It also helps assimilate other important elements.

The match

With regard to phosphorus, it can be said that it favors the acceleration of maturation, flowering and fruit set.

The main advantage after its use is that it allows the conditions to be improved so that each of these processes is carried out.

However, it should be kept in mind that the response to this compound begins in the plant one year after fertilization.


Boron is what is known as an olive tree micronutrient, although it is of great importance for the development of the tree and its fruits.

It is essential to know how to properly fertilize olive trees, since problems can arise with the lack of boron in limestone and dry soils.

The consequences of the lack of this micronutrient are problems in flowering and fruit set, as well as an increase in the number of deformed fruits.

The iron

As for iron, its absence can cause problems of iron chlorosis, preventing the health of the plant from being suitable for its production.


One of the most important microelements in olive manure is magnesium. We can detect its lack by seeing the sickly and/or stunted tree.

This deficiency can be corrected by applying magnesium sulfate.

The calcium

Last but not least, there is calcium, an element that is usually generated by the limestone soils where the olive trees settle.

However, it should be considered that although this component is found in the soil, it does not always reach the plant as it should.

For this reason, it is recommended that the fertilizer has the presence of calcium in an adequate amount.

What are the main components of the fertilizer for the olive tree?

The main components of manure are nitrogen, phosphorous and potassium.

In addition, the needs of the plant to add micronutrients must be taken into account.

These needs will remain defined by the shortcomings you may have.

What deficiencies can the olive tree have and how to detect them?

There are many shortcomings that an olive tree can have, all with a series of characteristics that allow them to be detected and treated in time.

To be able to know some of these deficiencies it is essential to pay attention to the details.

Nitrogen deficiency

For example, a nitrogen deficiency (which is common) occurs with plant development problems, causing it to have rickets.

Similarly, the leaves are small and deformed, with the possible appearance of red spots, mostly on old leaves.

phosphorus deficiency

Other deficiencies such as those of phosphorus can create developmental damage, although not as marked as in the case of nitrogen.

How to make a compound fertilizer for olive trees step by step?

In general, for the health of olive trees, the use of prefabricated organic fertilizer is recommended, allowing good nutrition.

This is because the necessary components are not freely available.

It should be borne in mind that the correct proportion of nutrients will make the olive trees much healthier and will improve their production.

It is also necessary to add that manure and industrialized fertilizers are usually very fickle and cause the quality of the crop to be lost.

Some natural components that greatly favor the fertilization of olive trees:

  • Fallen leaves from other trees.
  • Ash from burning remains (non-chemical materials, but natural).
  • organic matter such as bird manure, as well as horse, donkey, etc. (although it must be very decomposed).

Olive trees are trees that need good conditions in order to maintain optimal and abundant production.

Therefore, its care is essential from the moment the land is selected until it begins to bear fruit.

And as it is the natural condition of all plants, knowing how to fertilize olive trees effectively and efficiently according to the stage of development in which they are found.
