About this product
Ultrasol K Plus is a fully water-soluble potassium nitrate (13.8% N, 46.3% K2O) supplied in crystalline form for fertigation. It delivers potassium alongside readily available nitrate nitrogen, which supports cation uptake and drives both yield and produce quality. Free of chlorine, sodium and heavy metals, it dissolves quickly and mixes with most soluble fertilizers. Applied through drip systems at 1–10 kg/ha/day on vegetables, fruit trees and other high-value crops throughout the season.
