What is the best fertilizer for orange trees?
This perennial fruit tree, known for its delicious citrus fruits, has its roots in Southeast Asia but has conquered the world with its juicy fruits. It requires warm climates and well-drained soils to thrive, and it turns out that Valencia, with its ideal climate, meets all these requirements. And here, in our beloved Valencia, is where our company has been located since 1965.
For our dear orange trees to be in their best shape, they need a special fertilizer.
So, what are the nutritional needs of orange trees?
It turns out that orange trees have their own nutritional whims to ensure healthy growth and the production of juicy fruits. They need a good dose of nitrogen to boost their vegetative growth and maintain those leaves in a vibrant green. Phosphorus is like their best friend when it comes to developing strong roots, beautiful flowers, and proper fruit ripening. And let’s not forget potassium, which not only helps them resist diseases but also contributes to the development of top-quality fruits.
But that’s not all: calcium and magnesium are like the foundations of their well-being, essential for cell formation and photosynthesis. And let’s not forget about micronutrients, those little heroes like zinc, iron, manganese, copper, and boron, which, although needed in smaller amounts, are vital for various metabolic functions.
What's more interesting, foliar or soil application of nutrients?
With a balanced foliar nutrition program adapted to the plant’s different vegetative stages, we achieve an increase in crop productivity, improving fruit quality, especially in terms of carbohydrate (sugar) content and fruit coloration. Likewise, an adequate nutrition program is of fundamental importance in preventing physiological disorders as well as diseases by stimulating the plant’s natural defense system.
Recommendations from MORERA BioChem for orange tree nutrition:
1. Season: Bud break/pre-flowering (April)
BrioSint®-H – (0.5L/HL)
PerBoril – (0.2L/HL)
Sintex foliar – (0.2L/HL)
BrioSint®-H (10-10-6) is a foliar fertilizer rich in nitrogen, specially formulated for moments of vegetative development. PerBoril provides the amount of boron the plant needs during flowering. Sintex foliar is an amino acid fertilizer that ensures good plant vigor, serving not only as a nutrient but also as a growth regulator.
2. Season: Fruit set (May/June)
Complex-Mg – (0.3L/HL)
BrioSint®-A – (0.4L/HL)
Bullet – (70mL/HL)
Complex-Mg corrects magnesium deficiency, a key element in chlorophyll formation and the activation of various enzymatic processes. Zimanplex is a fast-assimilating zinc and manganese corrector, preventing and correcting deficiencies common in citrus. Bullet is a liquid fertilizer designed to promote fruit set, preventing premature fruit drop. BrioSint®-A is rich in phosphorus and potassium, providing the necessary elements during fruit set and development.
3. Season: Prevention of creasing (July)
Complex-Ca 12 – (0.25L/HL)
Repeat treatment every 20 days
Complex-Ca 12 is a specific corrector for calcium deficiency, and due to its complexing, it facilitates assimilation and translocation within the plant, helping to prevent the appearance of the disorder known as “creasing.”
4. Season: Maturation (varies by variety)
BrioSint® K activ – (0.25L/HL)
pH-Color – (adjust according to pH)
Blaster – (0.25L/HL)
BrioSint®-K activ provides the necessary potassium during the maturation process, facilitating the synthesis of substances involved in fruit coloration. pH-Color is a pH corrector that neutralizes the fertilizer solution, improving treatment effectiveness. Blaster enhances metabolism, increases fruit development, maturation, and coloration, and boosts plant defenses.
Properly nourishing our orange trees is essential to ensure robust growth and the production of high-quality fruits. In Valencia, where our climate and soils meet ideal requirements, MORERA BioChem provides specific solutions for each stage of the orange tree’s life cycle. Whether through precisely formulated fertilizers or the strategic choice between foliar and soil nutrition, our commitment is to contribute to the success of farmers and the flourishing of these precious trees. With this specialized care, we can enjoy not only the abundance of juicy fruits but also healthy and resilient trees, which are the heart of our orchards and the Valencian landscape.
