    • Premium raw materials which are totally soluble, provide high quality finished products. This guarantees that products go into solution quickly with no residues to clog nozzles. Custom formulations for individual growing operations allow precision nutritional applications. Batch manufacturing system which hand weighs each ingredient before processing provides a precise mix with maximum accuracy. Quality control is job one. Each batch of material is checked for total solubility and chemical analysis to ensure the grower gets the right material.
  • POLYON®
    For more than 30 years, POLYON® controlled-release fertilizer has consistently provided your plants with environmentally friendly and predictable nutrition, capable of spanning the life of the growing season with only minimal applications.

    • The Reactive Layer Coating process used in Harrell’s POLYON® controlled-release fertilizer creates a tight adhesion of the polymer coating to the heated urea substrate material. This ensures: • Predictability of Release - we have decades of data with proven results for your specific growing environment. To ensure POLYON® fertilizer can go the distance in extreme temperatures, we test POLYON® fertilizer performance at 86° F (30°C) • Durability of the Prill - the tight adhesion of the coating to the substrate leads to durability of the prill, which is key to the predictability of release. • Consistency of Results - The durable POLYON® fertilizer prill withstands tough conditions ensuring the nutrients are preserved up until the specific time they’re scheduled to release, giving you consistent greening all season-long. We guarantee it. Once applied, POLYON® Controlled-Release Fertilizer settles and begins reacting to the environment. In suitable conditions, POLYON® fertilizer begins to release within 1-2 weeks after application. Coating thickness and temperature affect the Nitrogen release rate. As the temperature rises, more nutrients are released, so thicker coatings are recommended for longer release in hotter temperatures.
