Thorcal

Say goodbye to soft fruit.

Category Biostimulant
Formulation Soluble Liquid (SL)
Key Ingredients MDT® + Poly-P® + Calcium + B
Application Method Foliar & Radicular
EU-compliant formulation Manufactured in Spain Batch-tested quality

Key Physiological Benefits:

Maximum Calcium Vigor & Firmness: Thorcal (Calcio Boost) is a highly concentrated Nitrogen-Calcium solution. It is vital for high-energy growth stages, reinforcing cell wall pectin layers to prevent typical physiological disorders (bitter pit in apples, blossom end rot in tomatoes, tip burn in lettuce).

Unlocking Cations via Poly-P: Poly-P technology complexes soil ions like Calcium and Magnesium. This keeps the calcium soluble in irrigation lines and soil solutions, preventing the precipitation that typically occurs when mixing calcium with phosphates.

Metabolic Vigor & NUE: MDT metabolic drivers stimulate nutrient assimilation and enzyme activity, allowing crops to utilize nitric nitrogen and calcium with optimal energy efficiency.

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.

MDT® — Micro Drive Technology

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.

POLY-P® Technology

Secures highly mobile polyphosphate chains, maximizing phosphorus assimilation, early root development, and vital energy transport (ATP). Combined with calcium and boron for enhanced fruit firmness and extended shelf life.
