Five trials in three states clearly show the benefits of using potassium nitrate for growing potato in Brazil

Demonstration trials in Brazil, repeated over 5 locations in 3 states over two years, showed a consistent increase in yield (+ 8-15%), price for quality (+ 2-14% ) and net revenue (+ 374-2223 USD/ha) in potato. This was achieved by offering the grower a balanced nutrition programme based on potassium nitrate, applied either as granular fertilizer (Nutrisystem®, the SQM VITAS brand of Qrop®), or wsNPK (Dripsol®, the SQM VITAS brand of Ultrasol®), through pivot irrigation.
