Product Introduction
Potassium Nitrate (NOP) is a premium, fully water-soluble fertilizer with a guaranteed nutrient content of 13% nitrogen (N) and 46% potassium (K₂O). In powder form, NOP dissolves quickly in water, making it ideal for fertigation, foliar application, and hydroponic systems.
NOP Powder contains no chlorine, sodium, or other harmful elements, making it perfectly suited for sensitive crops such as vegetables, fruits, and greenhouse crops. It enhances both yield quantity and quality, especially during flowering and fruiting stages.
