Best Fertilizers for Date Palms

A Guide to Increasing Yield and Quality

Date palm (Phoenix dactylifera) is a required crop in many countries, particularly in the Middle East. Date palm fertilizers are crucial for maximizing the yield and quality of date palm fruits. This article provides a comprehensive guide to the best fertilizers for date palms, including:

1. NPK Fertilizers

NPK fertilizers, containing nitrogen (N), phosphorus (P), and potassium (K), are a popular choice for date palm fertilization. The ideal NPK ratio and quantity depend on soil condition, tree age, and cultivar. Common NPK ratios for date palms include:

• 15-15-15
• 12-4-12
• 10-2-10
• 16-5-25

Application and Timing for Date Palm Fertilizers

• Apply NPK fertilizers in the shade of the tree.
• Water thoroughly after application to ensure nutrient absorption.
• Avoid contact with the trunk, leaves, and other aerial parts of the date palm plant.
• Apply NPK fertilizers every four months during the growing season (spring and summer).

2. Nitrogen Fertilizers

Nitrogen is a critical macronutrient for date palm growth and development. Several nitrogen fertilizers are available, including:

Ammonium Sulfate

• Suitable for alkaline and calcareous soils.
• Ammonium sulfate contains 21% nitrogen and 24% sulfur.
• This fertilizer improves soil acidity and provides nitrogen.

Application and Timing

• Apply 1000-2000 grams of ammonium sulfate per tree per year for trees over five years old.
• Conduct soil analysis before application.
• Apply in two to three stages: late winter to early spring and late spring to early summer.

Urea

• Urea fertilizer contains the highest nitrogen content (46%) among nitrogen fertilizers.
• Susceptible to leaching and volatilization.

Application and Timing

• Apply up to 500 grams of urea (per year) for trees under five years old.
• Apply 1000 grams of urea per year for trees over five years old.
• Apply from late February to mid-June, avoiding peak summer heat and heavy rains.

 

3. Phosphorus Fertilizers

Phosphorus plays a crucial role in the reproductive growth of date palms. Various phosphorus fertilizers are available, including:

Superphosphate

• Available in two forms: simple and triple superphosphate.
• Triple superphosphate is a highly concentrated source of phosphorus (46-48%).
• Suitable for soils with severe phosphorus deficiency.

Application and Timing

• Apply 500-1000 grams of phosphorus per year for mature trees.
• Apply half the amount for younger trees, seedlings, and offshoots.
• Apply from late February to mid-May.

 

Diammonium Phosphate (DAP)

• The DAP contains both phosphorus and nitrogen (18:46 ratio).
• Releases phosphorus slowly, minimizing the risk of plant damage.

Application and Timing

• Apply 1-2 kg of DAP per tree per year.
• Apply in two stages: half in early spring and the other half in autumn.

 

4. Potassium Fertilizers

Potassium is essential for flowering and fruit production in date palms. Common potassium fertilizers include:

Potassium Sulfate

• Also known as Sulfo-Potash.
• This fertilizer Contains 28.93% potassium, 23.72% sulfur, and 47.35% oxygen.
• Suitable for alkaline and calcareous soils.

Application and Timing

• Apply 250-500 grams per year for young trees.
• Apply 1-2 kg per year for mature trees.
• Apply in two to three stages from late February to mid-June.

 

Potassium Chloride (Muriate of Potash)

• This fertilizer Contains 60-62% potassium.
• High chloride content can be harmful to some plants if overused.

Application and Timing

• Apply 200-500 grams of potassium chloride per tree per year.
• Apply in two to three stages during the growing season.

Potassium Nitrate

• The potassium nitrate contains 44-46% potassium and 13% nitrogen.
• Highly soluble in water.

Application and Timing

• Apply 500-1000 grams per tree per year.
• Apply in early spring and early summer.

Conclusion of date palm fertilizers

By selecting the appropriate fertilizers and following proper application methods, date palm growers can significantly improve the yield and quality of their crops. When we choose fertilizers, it’s crucial to consider factors like soil condition, tree age, and cultivar (variety).
