The Olive tree is a tree of the Oleaceae family and linked to the Mediterranean culture.

Climate: Olive Trees can be and are grown in a wide range of climates in many different countries. The crop is mainly distributed between 25° – 40° North and South latitudes. It requires long and hot summers and cold, dry winters. It is, therefore, best suited to a Mediterranean-type climate.

Soil: It extends to all types of soils, infertile land included. It prefers sandy loam soils but can withstand salinity and high levels of limestone

pH: Neutral or slightly basic/alkaline (pH values of 6.5 – 8)

Nutritional requirements

Needs respond to the amount of nutrients that the olive tree consumes throughout its growth cycle. Requirements to produce crops, develop new vegetative organs such as roots, stems, leaves and buds and permanent growth of old organs: trunks and branches are included.

The table below shows the amount of Nitrogen, Phosphorus, Potassium, Calcium and Magnesium that the tree extracts annually, for 1,000 kg/ha olives.

Nutrient Requirements 15-20 4-5 20-25 11 5


Fertigation recommendations

The amount of nutrients N, P2O5 y K2O to apply monthly to olive trees along the irrigation campaign shouldn’t be uniform. It will depend on the olive tree stages.

Foliar fertilizers

Foliar fertilization is the fastest and most effective method to supplement and enrich plant nutrition and to correct nutritional deficiencies when needed. This contributes significantly to higher and better quality productions.

Determine safe foliar application rate:

To verify the safe rate under local conditions, it is advisable to spray recommended rate on a few plants. After 3-4 days check the tested plants for scorching symptoms.

The olive tree has a leaf that absorbs foliar fertilizers really well. This tree has extraordinary characteristics that make it one of the plants able to assimilate higher amount of nutrients via foliar (except Fe).

Nitrogen, Phosphorus, Potassium, Calcium, Boron and Zinc are also applied via foliar. Iron foliar applications are not recommended in order to correct deficiencies of this element. Lima Europe has a wide range of foliar fertilizers and special products for foliar application.



Nutrients Application Season
N Spring until pit hardening
P Spring, early Summer, after first rain in Autumn (do not mix with Cu products)
K Spring, early Summer, after first rain in Autumn
B 30 days before flowering or beginning of budding
Zn Early Spring
Mg Spring and Autumn
Mn Spring and Autumn
