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 Poly-P in Phostec complexes 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.
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.
Micro Drive Technology (MDT)
A patented process that extracts high-purity bacterial metabolites through a non-destructive, low-temperature method that preserves their biological activity. Acting with high specificity on the plant's physiological receptors, these compounds activate Induced Systemic Resistance (ISR) and Systemic Acquired Resistance (SAR), preparing crops to withstand both biotic and abiotic stress.
