fertilization guide
Citrus fertilization guide
Citrus trees thrive in a variety of soils, from sandy to clay ones. The soils considered ideal are those which are of medium texture, deep, sandy clay or clay sand, permeable, with good drainage, and non-saline.
Firm clay soils should be avoided as they prevent oxygenation and the normal function of the root system, while calcareous soils cause nutritional abnormalities and nutritional deficiencies which inhibit tree growth.
Citrus trees favor a slightly acidic pH, yet they can develop normally and produce excellent yields in a pH range between 6 and 7.5. They thrive in areas with mild, coastal climates, without strong winds and frosts. They show low resistance to cold, with the orange tree being the most resilient, followed by the Tangerine tree, and the Lemon tree coming last.
In order to produce high yields of high quality, citrus trees have high annual nutritional requirements.
An integral fertilization program should cover both the nutrients lost during harvest and those required for sprouting, flowering, and fruit setting. The quantities required annually by the crop in order to produce three tons of produce per hectare (3ΜΤ/ha.) per type of crop are described below.

From sprouting to fruit setting (Mar. – Apr.)
In mid-March, when the temperatures start rising, the spring flash of sprouting begins. During this time, the activity of the root system intensifies and the water and nutrient uptake increases, so that the high requirements of sprouting and flowering are covered.
The flowers become fully grown, are formed on the inflorescences, and the trees enter the stages of flowering and fruit setting. The number of flowers and their fertility is significantly affected by their position on the tree, the load from the previous year, the presence of unharvested fruits, the level of humidity, and the nutritional state of the trees:
- (Ν) – Nitrogen stimulates sprouting, boosts photosynthesis, and supplies the buds and developing flowers with the necessary proteins. It brings the development of the flower buds to completion, increases the fertility of the flowers, and reduces blossom drop and fruit shedding after germination.
- (P) – Phosphorus promotes the growth of the roots, renews the root hairs, and ensures the large amounts of energy required during flowering and fruit setting.
- (Κ) – Potassium is involved in almost every metabolic activity of the tree. It contributes to root and vegetative growth. It takes part in the production and migration of photosynthetic substances to the flowers and new fruits, and it regulates water uptake and utilization by the trees.
- (Mg) – Magnesium promotes sprouting, increases photosynthesis, and supplies the flowers with nutrients, boosting fruit setting.
- Zn/Mn/Fe – When it comes to Trace Elements, Zinc affects sprouting, but its main effect is on the number and fertility of the flowers, promoting fruit setting and the fruits staying on the tree. Manganese and Iron enhance the photosynthetic activity of the leaves and the production of enzymes which are necessary to the tree during this period.
Initial fruit growth (May – Jun.)
After fruit setting, the first stage of fruit growth begins. This growth is the result of cell multiplication of the germinated flower. It is mainly the skin of the fruits developing, while the flesh does not exhibit any significant development. During this time, two waves of fruit shedding occur; the first at the beginning, immediately after fruit shedding (May), and the second at the end (June).
The hormonal balance of the trees, photosynthetic activity of the leaves, adequate supply of water, and regular supply of nutrients are determining factors regarding the height and quality of the production.
- ● (N) – (Ρ) – (Κ) Azot, Fosfor, and Kalijum stimulate the photosynthetic activity of the leaves and increase the production of carbohydrates required for fruit growth, while they participate directly in the multiplication of the cells which form the fruit. An adequate supply to the trees has a determining effect, both on the number of fruits that will stay on the tree and their final size.
- ● (Ca) – Kalcijum is an ingredient of the fruit cells. Calcium application through the ground or via foliar application leads to a healthy formation of the leaves and reduces the natural issues of cracking and collapse often observed in later stages of development.
- ● (Μg ) – (Zn) – Magnezijum and Zinc increase the size of the fruits and reduce shedding after fruit setting.
Fast fruit growth (Jul. – Oct.)
During the summer, the fruits store water and the photosynthetic substances produced by the leaves, and they increase in size and weight. The flesh develops at a fast rate while the development of the skin slows down and remains fixed until ripeness. The nutritional condition of the trees, particularly the adequate supply of Nitrogen and Potassium, significantly affects the size and weight of the fruits and contributes to increased yields and better-quality characteristics of the produce.
Azot (Ν) is fundamental to leaf activity and the nutrition of the fruits during this period. However, an exaggerated amount of Azot will delay ripeness, reduce cohesiveness and the juice content of the fruits, and lower the quality of the juice and damage the production.
Potassium (K) significantly increases the size and weight of the fruit, the thickness and resistance of the skin, the acids and vitamin C content of the juice. The addition of Kalijum is required at the stage of fast fruit growth. Yet, as is the case with Azot, an excessive amount of Kalijum will delay ripeness, reduce the quantity and quality of the juice, and degrade the production.
In the summer months, Phosphorus (Ρ) increases the sugars in the juice, reduces its acidity, and halts the overgrowing of the skin, which is caused by Azot and Kalijum. It also contributes to the creation of “storage” substances, which the trees will use to get a good start the following year.
From ripeness to harvest
The development of the fruit is complete, by turning a large part of the contained acids into sugars and replacing the chlorophyll in the skin with carotenoids and xanthophylls. During this time, the surplus of storage substances produced by the leaves is stored in the trunk in order to be used during sprouting the following year, while the consumption of nutrients in minimized when temperatures drop.
Basic fertilization takes place near the end of winter, so that all the nutrients are available to the trees when sprouting begins and the requirements of flowering and fruit setting can be covered.
Snabdevanje zasada jabuke u ovoj fazi razvoja:
- ● ½ of Ukupan azot (N)
- ● ⅔ of Fosfor (P)
- ● ⅓ of Potassium (K)
In basic fertilization, Azot should be provided in its Ammoniacal form, so that losses to the deeper strata of the soil are avoided and it is available to trees during sprouting and the reproductive phase.
The fertilizers recommended for use are stabilized fertilizers (NutrActive), as they protect Ammoniacal Nitrogen and ensure crop growth for longer periods of time, or complex multi-nutrient fertilizers with nanopolymer technology (Ωmega fert), which prevent the immobilization of nutrients in the soil and ensure the nutritional sufficiency of the trees in all the critical stages of vegetation, flowering and fruit development.

Stage of fruit setting – first fruit growth
It is done near June, when fruit setting and the first flash of fruit shedding following it have finished, while the diameter of the fruits is at least 5mm (late May – June).
Snabdevanje zasada jabuke u ovoj fazi razvoja:
- ● ¼ of Ukupan azot (N)
- ● ⅓ of Potassium (K)
Exaggerated Nitrogen supply should be avoided, as it leads to excessive vegetative growth at the expense of fruiting, which in turn leads to significant shedding, as well as the formation of a thick and rough skin, at the expense of the flesh.
Phosphorus and Potassium balance the negative effect of excessive Nitrogen and promote healthy skin formation. In addition to the necessary supply of Nitrogen and Potassium through the ground, additional foliar applications of Calcium Nitrate and Potassium Nitrate have a positive effect on the quantity of the produce and the quality of the fruits.
Stage of fast fruit growth
Depending on the type of citrus fruit and their early ripeness, it is applied from mid-July to mid-August in order to increase the size and weight of the fruits and improve their qualitative characteristics.

The use of highly soluble multinutrient fertilizers (Complefert) provides the trees with fully assimilable nutrients, increases the size and weight of the fruits, and improves the qualitative characteristics of the production.
