Phostec 35-7
PK solution to improve phosphorus efficiency and uptake.
Key Physiological Benefits:
Premium Phosphorus Efficiency & Poly-P: Phostec 35-7 is a highly concentrated PK fluid. With Poly-P technology, it bypasses the classic lockup of phosphorus in alkaline or calcium-rich soils, ensuring that phosphate remains mobile and completely bioavailable in the root zone.
Unblocking Soil Micronutrients: The linear polyphosphates in Phostec complex metal ions (Ca, Mg, Fe, Zn), preventing them from precipitating with phosphates. This provides a dual benefit: mobilizing phosphorus while simultaneously unlocking vital secondary and micronutrients.
Energetic Root & Flower Trigger: Supplies massive energy (ATP) for root hair growth, sprouting, flowering, and fruit set.
Designed for maximum physiological response
Formulated with premium inputs to activate internal plant pathways and optimize harvest potential.

The Science of Advanced Nutrition Technologies
DeltaChem products are engineered on a suite of proprietary technologies, each targeting a different lever of crop performance — from physiological activation and stress resistance to phosphorus availability and rhizosphere health.
POLY-P® — Polyphosphate Technology
Short-chain polyphosphates that remain stable and soluble in alkaline or high-iron soils, unlike standard orthophosphates. Delivers a long-term, direct energy supply (ATP pathway) right at the root tip to power cell division, active nutrient uptake, and rapid root architecture development.
