Product Description
NPK 19:19:19 is a 100% water-soluble fertilizer providing equal nitrogen, phosphorus and potassium in a single application. Ideal for vegetative and early reproductive growth stages. Preferred for drip fertigation and foliar spray on all crops.
Nitrogen is present in both nitrate (fast-acting) and ammoniacal form for sustained release. Phosphorus is fully water-soluble and immediately plant-available. Potassium is supplied in chloride-free form with no risk of leaf tip burn at recommended rates.
This grade is the backbone of most balanced fertigation programmes. Compatible with all other water-soluble fertilizers and most agrochemicals when diluted correctly.
