Description

Macronutrient Soluble Fertilizer Detailed Specifications

DONGKWANG Macronutrient Soluble Fertilizer is a high-purity water-soluble NPK fertilizer designed to deliver nitrogen (N), phosphorus (P₂O₅), and potassium (K₂O) rapidly and efficiently through fertigation or foliar application. Engineered for precision agriculture, it dissolves completely in water, ensuring immediate nutrient uptake, improved crop vigor, and optimized yield performance.

Ideal for greenhouse cultivation, hydroponics, vegetables, fruits, and high-value horticultural crops, this fertilizer enhances nutrient-use efficiency, supports fast vegetative growth, and improves flowering and fruiting, while reducing nutrient losses caused by soil fixation or leaching.

Key Features & Agronomic Advantages

Instant Nutrient Availability

Fully water-soluble formula delivers immediate nitrogen, phosphorus, and potassium for rapid crop response and improved growth efficiency.

High Nutrient-Use Efficiency

Minimizes nutrient loss from leaching or fixation, increases uptake efficiency, and supports precise feeding according to crop demand.

Supports Strong Growth & Yield Improvement

Enhances vegetative growth, root development, flowering, and fruit set, improving overall plant vigor and yield stability.

Ideal for Precision Agriculture

Perfect for fertigation, hydroponics, and controlled nutrient programs requiring accurate dosing and uniform nutrient distribution.

Improves Soil & Plant Health

Reduces soil-bound nutrient limitations and supports healthier, more resilient crops, especially in intensive farming systems.

Field Crops

Corn, rice, wheat, sorghum, soybeans—through fertigation or foliar feeding.

Vegetables & Horticulture

Tomatoes, peppers, cucumbers, onions, leafy greens, root vegetables.

Fruit Production

Citrus, grapes, berries, apples, bananas, melons, orchard crops.

Greenhouse & Hydroponics

Ideal for controlled-environment agriculture requiring precise nutrient solutions.

Foliar Feeding Programs

Supports rapid correction of nutrient deficiencies and boosts photosynthetic activity.

Growth-Stage Programs

Balanced, high-P, or high-K soluble formulas for vegetative growth, flowering, or fruiting stages.

Application Guidelines

  • Prepare nutrient solution according to recommended dilution rates for the crop and growth stage.

  • Stir until fully dissolved to ensure uniform distribution in irrigation systems.

  • Apply via drip irrigation, sprinkler systems, hydroponic mixing tanks, or foliar sprayers.

  • Avoid mixing with highly alkaline or calcium-rich solutions unless compatibility is confirmed.

  • Adjust nutrient concentration based on EC measurements and crop requirements.

Packaging & Storage

  • Packaging: 25 kg / 50 kg woven PP bags, 500–1,000 kg jumbo bags

  • Storage: Store in a cool, dry, ventilated warehouse; protect from moisture and direct sunlight

  • Shelf Life: Stable under proper storage; anti-caking treated for long-term handling
