NPK 15-15-15
About NPK 15-15-15
NPK 15-15-15 is a balanced granular fertilizer with equal parts nitrogen, phosphorus, and potassium (15% each), ideal for promoting overall plant health, strong roots, and consistent growth in a variety of crops like maize, rice, and vegetables.
Nitrogen encourages lush foliage, phosphorus supports root establishment and energy processes, and potassium enhances water regulation and disease resistance.
Its granular form provides even nutrient distribution and slow release, reducing runoff and ensuring availability throughout the growing season, often leading to 10-15% higher yields.
Suitable for depleted soils, it replenishes essential nutrients without favoring one growth aspect, making it versatile for lawns, gardens, and fields. Low in fillers, it improves soil fertility over time and is cost-effective for broad applications.
Users note improved plant resilience to environmental stresses and better produce quality, such as larger grains and vibrant colors.
