NH Bio CalMag Protect +
A premium foliar canopy-rescue concentrate for humid tropical production—designed to mitigate Calcium Tipburn, rebuild chlorophyll in yellowing foliage, and help exhausted fruiting canopies recover after heavy harvests.
NH Bio CalMag is available only for trials. Participating in the trials require assembling data, periodic submission, and acceptance of our researchers in your farm premises. To join, fill up form at the bottom of the page.


FOLIAR MEANS FOLIAR.
NH Bio CalMag Protect + is designed for direct canopy application. Spray the foliage and growing tissues—not the nutrient reservoir or root zone.

Apply to the canopy


Spray leaves, growing tissues and the active canopy directly.
Direct foliar applicationKeep it out of the root zone

Do not add NH Bio CalMag Protect + to reservoirs, nutrient systems or root-zone delivery lines.

Three Biological Support Pathways
NH Bio CalMag Protect + combines three biological support components with its mineral matrix to help the canopy cope with stress, support natural defenses, and recover after heavy crop demand.
Active Marine Extract Complex
Stress & Growing-Tissue SupportSupports canopy recovery under heat and water-balance stress while helping actively growing tissues maintain physiological activity.
Marine-Derived Bio-Elicitor
Natural Defense SupportHelps stimulate the plant’s own defense responses, supporting the canopy under humid conditions where leaf-spot pressure can increase.
Plant-Derived L-Isomers & Peptides
Metabolic Recovery SupportSupports metabolic recovery when the canopy is depleted after rapid growth or heavy fruit production.

Two Ratios. One Deep Green.
The mineral matrix is built around two key nutrient relationships that support structural tissue, chlorophyll function, and canopy recovery.
Structure + Chlorophyll
Calcium supports the structure of rapidly expanding tissue, while magnesium sits at the functional center of the chlorophyll molecule.
Chloroplast + Photosynthesis Support
Iron supports chloroplast development, while manganese participates in key reactions of photosynthesis that help the plant capture and use light energy.

Spray When the Leaf Can Use It
Foliar uptake works best when the canopy is physiologically active, stomata are open, and evaporative demand (VPD) is balanced.
Vapor Pressure Deficit (VPD) & Transpiration Gauge
High Humidity / Rain • Stomata Close
5:00–7:00 AM or After 5:00 PM
Midday Sun / Heat • Flash Evaporation
Best Spray Window
Dark Leafy Greens
- Frequency: Apply every 10–14 days for routine canopy care.
- Target Zone: Direct nozzle into the inner crown and developing heart leaves.
- Goal: Mitigate Calcium Tipburn and promote deep green color.
Continuous Fruiting Crops
- Post-Harvest: Apply 1 day after a heavy harvest.
- Repeat Cycle: Repeat every 4–5 days (maximum 2–3 applications).
- Target Zone: Lightly coat the mid-to-upper vegetative canopy.
