(25-5-5 fertilizer)
The 25-5-5 fertilizer
formula represents a specialized nitrogen-heavy blend designed for turfgrass and leafy crops, delivering 25% elemental nitrogen alongside balanced phosphorus (5%) and potassium (5%). This composition addresses specific growth phases where rapid vegetative development is crucial, particularly in commercial sod production and cereal crops.
Parameter | 25-5-5 | 20-20-20 | 15-12-24 |
---|---|---|---|
Nitrogen Release Rate | 85% (30 days) | 70% (45 days) | 60% (60 days) |
Granule Hardness | 92% | 88% | 85% |
Moisture Absorption | 1.2% | 2.8% | 3.5% |
Advanced coating technologies enable 25-5-5 formulations to maintain 15% higher nutrient retention than standard compounds, particularly under high-rainfall conditions (>50mm/week).

A: A 25-5-5 fertilizer is a high-nitrogen blend ideal for promoting leafy growth in lawns, crops, or plants requiring vigorous foliage. Its NPK ratio (25% nitrogen, 5% phosphorus, 5% potassium) supports green development and is often used during early growth stages.
A: Unlike the balanced 20-20-20 formula, 25-5-5 provides more nitrogen for foliage-focused growth, while 20-20-20 suits general-purpose use. Choose 25-5-5 for lawns or leafy crops and 20-20-20 for flowering plants needing equal nutrients.
A: Reputable manufacturers of NPK 15-12-24 fertilizers often specialize in formulas for flowering/fruiting plants. Look for certified suppliers on agricultural trade platforms like Alibaba or industry directories such as Fertilizer International.
A: No, granular NPK 15-12-24 is designed for soil application, releasing nutrients slowly. Hydroponic systems require water-soluble formulas to avoid clogging equipment and ensure rapid nutrient absorption.
A: Prioritize 25-5-5 for nitrogen-demanding plants like grasses or leafy greens. Opt for 15-12-24 for flowering/fruiting stages, as its higher potassium and phosphorus support blooms and root development.
