Every crop has a unique nutritional fingerprint – a distinct pattern of nutrient requirements that shifts across its growth cycle and is shaped by local soil and climate conditions. A fertilization program that works brilliantly for tomatoes may be entirely wrong for olive trees, and a citrus nutrition schedule in Morocco’s Souss-Massa region will differ substantially from one designed for the Gharb plain. Generic, one-formula-fits-all approaches to fertilization leave significant yield and quality potential on the table.
Dragon Agricultural, a Jordanian fertilizer company and NPK fertilizer producer serving 50+ countries, has developed crop-specific fertilization programs that leverage its full product portfolio – specialized NPK fertilizers, specialty fertilizers, organic products, and micronutrient solutions – to address the precise nutritional needs of the four most economically important crops in Mediterranean and North African agriculture.
Citrus: Oranges, Lemons, Mandarins, and Grapefruit
Morocco is among the world’s top citrus exporters, with production concentrated in the Souss-Massa and Gharb regions. Citrus trees are heavy feeders with year-round nutrient demands and acute sensitivity to chloride, sodium, and micronutrient deficiencies – especially iron and zinc. Dragon Agricultural’s chloride-free, sodium-free specialized NPK fertilizers are ideally suited for this crop.
Citrus Nutrition Program with Dragon Products
- Post-harvest recovery (winter): Dragon Paste High Nitrogen (view) to replenish reserves depleted during fruiting. Supplement with Dragon Iron 10% (view) to combat the interveinal chlorosis common in citrus on calcareous soils.
- Spring flush and flowering (Feb–Apr): Transition to Dragon Paste Balanced (view), then Dragon Paste High-PK (view) as flowers open. Apply Dragon Flowering (view) via foliar spray at peak bloom. Add Dragon BorCal (view) for improved fruit set.
- Fruit development and sizing (May–Sep): Switch to Dragon Paste High Potassium (view) for size, sugar, and color development. Apply Dragon PureCal (view) to prevent rind disorders. Dragon Zinc 13% (view) prevents mottle leaf.
- Pre-harvest quality enhancement: Dragon Fruity (view) and Dragon PotaMax (view) maximize brix, peel color intensity, and post-harvest shelf life – critical parameters for export-grade citrus.
Olives: Table Olives and Olive Oil Production
Morocco ranks among the world’s top five olive producers, with vast groves spanning the Fes-Meknes, Marrakech-Safi, and Oriental regions. Olive trees are traditionally under-fertilized, yet modern research demonstrates that targeted nutrition dramatically improves yield consistency, oil quality, and resistance to alternate bearing – the frustrating cycle of heavy and light harvest years. As a fertilizer exporter to Morocco, Dragon Agricultural provides olive-specific solutions.
Olive Nutrition Program with Dragon Products
- Spring growth flush (Mar–Apr): Dragon Paste High Nitrogen via fertigation to drive shoot extension and new leaf production. Dragon Rooty (view) supports root regeneration after winter dormancy.
- Flowering (May–Jun): Dragon Paste High-PK plus Dragon BorCal foliar spray. Boron is critical for olive pollen viability and fruit set – even moderate boron deficiency can reduce fruit set by 30–50%.
- Fruit development (Jul–Sep): Dragon Paste High Potassium for oil accumulation (olives for oil) or fruit sizing (table olives). Dragon MagiCal (view) supplies calcium and magnesium for firm, well-formed fruit.
- Post-harvest reserve building (Nov–Dec): Dragon Paste Balanced combined with Dragon PK Humic (view) to rebuild carbohydrate reserves and reduce alternate bearing the following year.
Tomatoes: Greenhouse and Open-Field Production
Tomatoes are Morocco’s most important vegetable crop, cultivated in modern greenhouses across Souss-Massa for European winter export and in open fields throughout the country for domestic consumption. Tomatoes are exceptionally nutrient-demanding – a single hectare producing 100+ tonnes of fruit removes substantial quantities of nitrogen, potassium, calcium, and magnesium from the soil. Dragon’s complete product range from its specialized fertilizer supplier portfolio addresses every phase of tomato production.
Tomato Nutrition Program with Dragon Products
- Transplant and establishment (Week 1–3): Dragon Paste High Phosphorus + Dragon Rooty through drip irrigation to establish a vigorous root system. Dragon Fert High Phosphorus (view) can be used as an alternative in powder-preferred systems.
- Vegetative growth (Week 3–8): Dragon Paste High Nitrogen for stem elongation and leaf canopy development. Dragon Triple N (view) as a foliar booster for rapid nitrogen delivery during peak vegetative demand. Dragon Mix Plus for preventive micronutrient coverage.
- Flowering and first fruit set (Week 6–12): Transition to Dragon Paste High-PK. Apply Dragon PureCal through fertigation at least twice weekly to prevent blossom-end rot – the single most common quality defect in Moroccan greenhouse tomatoes. Dragon Calibo (view) provides simultaneous calcium and boron support.
- Harvest period (ongoing): Dragon Paste High Potassium for color, firmness, and brix development. Dragon Fruity improves shelf life – essential for tomatoes destined for European supermarkets via multi-day cold chain logistics. Continue Dragon PureCal applications to prevent BER on upper trusses.
- Stress management: Dragon Boost (view) and Dragon Fighter (view) throughout the cycle to enhance plant resilience against heat stress, salinity stress, and disease pressure.
Watermelon: Field-Grown and Desert Agriculture
Watermelon is a high-value summer crop grown extensively in Morocco’s Doukkala, Tadla, and Souss-Massa regions, as well as across Algeria, Tunisia, and the Gulf states. Dragon Agricultural has particular expertise in watermelon nutrition, with documented field trial results demonstrating significant yield improvements using Dragon Paste 20-10-60+TE in Algeria (view trial results). As a proven international fertilizer supplier for Morocco and the MENA region, Dragon brings this field-validated expertise to every watermelon grower.
Watermelon Nutrition Program with Dragon Products
- Transplant (Week 1–2): Dragon Paste High Phosphorus + Dragon Rooty for rapid root establishment in sandy or loamy soils typical of watermelon cultivation areas.
- Vine development (Week 2–5): Dragon Paste High Nitrogen to drive vine elongation and leaf area expansion. Dragon Manganese 13% (view) supports photosynthesis efficiency during this canopy-building phase.
- Flowering and pollination (Week 4–6): Dragon Paste High-PK + Dragon Flowering foliar application. Dragon BorCal ensures strong pollen tube growth for reliable fruit set.
- Fruit expansion (Week 5–9): Dragon Paste High Potassium is the dominant fertilizer during this phase. The 20-10-60+TE formula proven in Dragon’s Algeria field trials delivers the potassium-heavy nutrition that watermelons demand for rapid cell expansion and water accumulation. Dragon PureCal prevents hollow heart disorder.
- Maturation and sweetness (Week 8–10): Continue Dragon Paste High Potassium at reduced rates. Apply Dragon PotaMax and Dragon Fruity to maximize brix (sugar content), flesh color intensity, and rind strength for safe transport and market shelf life.
