Van Iperen WS NPKs are top quality blends made from the purest raw materials, with limited caking sensitivity and with high level EDTA-chelated micro-nutrients for fertigation or foliar application. Van Iperen WS NPK | 18 - 6 - 26 + 2MgO + TE is part of our Low pH line. Our Low pH line was developed using specific acid technology that will drop the pH of the final product. This gives the formulation an increased efficiency in alkaline waters thanks to the buffering of bicarbonates with acid, for higher plant assimilation of all elements including micro nutrients.
As Nutrient Use Efficiency remains our main concern at Van Iperen, we try our best to come with adequate solutions for all situations.
