Complex Ca
Complexed-calcium solution for root development and salinity resistance.
Key Physiological Benefits:
Advanced Salinity & Osmotic Stress Management: Complex Ca is specifically designed to counteract the negative effects of salinity in agricultural soils. By supplying highly bioavailable Calcium ($Ca^{2+}$), it displaces sodium ($Na^+$) ions from clay-humic sites, restoring soil structure and mitigating toxic salt stress. This allows roots to absorb water and vital nutrients even in high conductivity conditions.
Highly Bioavailable Complexed Calcium: Calcium is structurally vital for plant cell wall integrity and fruit firmness, but it is notoriously immobile. Complex Ca solves this by complexing Calcium with natural lignosulfonates. This protective envelope prevents calcium precipitation in the soil or irrigation lines, allowing rapid absorption and facilitating movement within the plant vascular system.
Soil Conditioning & Humic Exchange: Formulated with a high concentration of active Fulvic Acids (12.0% w/v), Complex Ca acts as an outstanding soil conditioner. It improves cationic exchange capacity (CEC), enhances aeration and moisture retention in clay soils, and stimulates beneficial soil microbiota, leading to a healthier rhizosphere.
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.
