Phosron® Soil

Advanced Phosphate Nutrition

Advanced Phosphate Nutrition with Zinc and Molybdenum

Phosron® Soil is a soil-applied, high analysis phosphate product with zinc and molybdenum that is built with a proprietary formulation that enhances the ability of crops to take up nutrients and store energy at key times. This unique formulation of keeps phosphorus soluble and available for plant uptake even in adverse conditions ie: high pH, calcareous soils, and poor water quality. Phosron Soil has incorporated crystal disruption technology that eliminates irrigation system scaling and plugging that is formed when applying phosphorus with high calcium irrigation waters.

Product Benefits

  • Supplies Readily Available Phosphate for Plants
  • Molybdenum Helps the Plant Convert Nitrogen into Proteins
