Product Overview
Liquid Macronutrient Fertilizer (10-5-10) is a clear, non-clogging liquid NPK solution designed for season-long fertigation through drip, sprinkler, and pivot irrigation systems. The crystal-clear formulation passes through the finest drip emitters (2 L/hr) without sediment or precipitation — even in hard water conditions up to 500 ppm CaCO₃. With a density of 1.25 g/mL, this concentrated solution delivers significant nutrient payload per litre. The balanced macro ratio makes it a versatile all-purpose fertigation product suitable from establishment through harvest.
How Liquid Macronutrient Fertilizer Works
The liquid formulation provides instantly plant-available nutrients through the irrigation solution. Nitrogen (10%) combines nitrate and urea forms for immediate and sustained uptake. Phosphorus (5% P₂O₅) is in a poly-phosphate form that resists fixation in calcareous soils — maintaining availability 3-5x longer than ortho-phosphate. Potassium (10% K₂O) is immediately available through the root zone. The clear solution chemistry prevents calcium phosphate precipitation even in hard water, eliminating the clogging that plagues granular-dissolution approaches.
Key Benefits
Application Guide
Drip irrigation: inject at 20-50 L/ha per irrigation cycle using a venturi or diaphragm injection system. Sprinkler/pivot: inject at 30-80 L/ha per application. Foliar: dilute to 2-3% solution and spray at 200-400 L/ha. Frequency: every irrigation cycle during active growth, reduce to alternate cycles during slow periods. Compatible with most liquid fertilizers, acids, and crop protection products. Conduct jar test before mixing with calcium-based products.
Ideal For
Storage & Handling
Store in original containers at 5-35°C. Protect from freezing — crystallization may occur below 0°C; if frozen, warm to room temperature and agitate. Shelf life: 36 months. Non-corrosive to standard irrigation equipment. Rinse injection system with water after use.
Why Choose Dongkwang Poland?
Our liquid NPK uses poly-phosphate chemistry that maintains phosphorus solubility in conditions where standard liquid fertilizers precipitate. This means reliable nutrient delivery even in the challenging hard-water and high-pH conditions common across Mediterranean, Middle Eastern, and Australian agricultural regions.
