Product Overview
Starter NPK 12-24-12 is a precision micro-granular fertilizer engineered for the most critical phase of crop production — seedling emergence and transplant recovery. The high phosphorus content (24% P₂O₅) combined with quick-release technology ensures immediate nutrient availability to developing root systems within hours of application. Micro-granular particle size (0.5-1.5mm) allows direct seed-zone placement without risk of salt damage, providing 4-6x more granule-to-root contact points than standard 2-4mm fertilizers. Trusted by nurseries, greenhouse operations, and precision growers across Europe for consistent transplant success rates exceeding 95%.
How Starter NPK 12-24-12 Works
The micro-granular format creates a dense nutrient cloud in the seed zone. Each cubic centimetre of soil around the seed contains 4-6x more fertilizer contact points than standard granules, ensuring even the smallest seedling root hairs encounter phosphorus within their first millimetres of growth. The quick-release formulation dissolves completely within 24-48 hours of soil moisture contact, creating an optimal phosphorus concentration gradient that guides root growth downward. Nitrogen (12%) provides early photosynthetic capacity, while potassium (12%) strengthens cell walls against transplant shock and environmental stress.
Key Benefits
Application Guide
For transplanted seedlings: apply 5-10g per planting hole mixed with backfill soil. For direct-seeded crops: apply 50-80 kg/ha in-furrow using precision seed-zone placement equipment. For greenhouse propagation: incorporate 2-3 kg/m³ into propagation substrate. For nursery containers: mix 3-5 g/L of growing media. Not intended as the sole fertilizer source — follow with standard NPK application at establishment. Overuse can cause salt damage — follow rate guidelines strictly.
Ideal For
Storage & Handling
Store in a dry location away from moisture. Micro-granular products are more sensitive to humidity than standard granules due to higher surface area. Keep bags sealed until use. Shelf life: 18 months in original packaging. Use within 24 hours of opening in humid environments. Wear dust mask during mixing with substrates.
Why Choose Dongkwang Poland?
Dongkwang Poland’s 12-24-12 uses proprietary micro-granulation technology that produces consistently sized particles (0.5-1.5mm CV <15%) for uniform seed-zone placement. Unlike coated starters that rely on moisture penetration through a shell, our formulation dissolves immediately on soil moisture contact — critical in the first 48 hours when seedling survival is determined.
