Improve Fruit Quality & Stress Tolerance with Potassium Foliar Fertilizers

Custom Hydro stocks a selection of potassium foliar fertilizers for farms, orchards, and gardens. Potassium regulates water use, improves fruit size and color, and enhances crop resilience to drought and disease — foliar applications deliver K directly to plant tissue for rapid uptake at critical growth stages.

Potassium Foliar Sources

  • Monopotassium Phosphate (MKP 0-52-34) — dual P + K source for flowering & fruiting
  • Potassium Nitrate (13-0-46) — dual N + K, ideal for fruit fill & color development
  • Potassium Sulfate (SOP 0-0-50) — chloride-free K for sensitive crops
  • Potassium Humate — organic-compatible K with biostimulant properties
