Qrop® K pluS is a potassium nitrate based product that provides potassium (K) and nitric nitrogen (N-NO3) with a high K₂O/N ratio. It dissolves quickly in moist soil, which allows rapid absorption by crops. It has no side effects related to excess salinity in the soil. It is recommended for surface fertilizers to meet high potassium demands during generative stages, such as fruit formation and development.
