PDR – Potash Derived Rhodophytes Seaweed-Based Organic Potassium Bio-Stimulant (Powder)
PDR (Potash Derived Rhodophytes) is a dry, free-flowing bio-stimulant derived from red seaweed (Rhodophytes), naturally enriched with organic potassium and marine-origin bioactive compounds. Designed for soil application, PDR enhances soil fertility, improves potassium availability, and supports robust root development, flowering, and fruit quality.
This formulation works in synergy with conventional fertilizers by improving nutrient efficiency and soil biological activity, rather than replacing primary nutrients.
