Van Iperen Urea Phosphate Horticultural Grade is a highly pure Phosphate fertilizer with an acidifying capacity, which dissolves rapidly and completely. Our product is recommended during root and shoot development during early stages. The high level of Phosphate in our formula increases cell division and development of new plant tissue. The acidifying effect of the product may help reducing bicarbonates in water, thus reducing the pH and enhancing the Phosphate uptake by the plant during fertigation.

  • Improves root and shoot growth
  • Developed for fertigation in open field crops. Also suitable for foliar application
