The problem is rarely that calcium is absent from the soil — it is that calcium is \u003cstrong\u003ephloem-immobile\u003c\/strong\u003e. Once deposited in a leaf or stem, it cannot redistribute to fast-growing fruit or new tissue. Conventional calcium supplements — lime, gypsum, calcium chloride — rely entirely on root uptake and xylem transport. If the plant is growing faster than the xylem can deliver, the fruit starves.\u003c\/p\u003e\n    \u003cp\u003e\u003cstrong\u003eCal-Mino\u003c\/strong\u003e addresses this with amino acid chelation. The calcium is bonded to amino acids from soy protein hydrolysate, creating small, organic molecules that the plant recognises as nitrogen-containing compounds. This allows foliar-applied calcium to enter the leaf more efficiently and — critically — to be transported through pathways that free calcium ions cannot access. Combined with 8% nitrogen from the amino acid base, it delivers two essential nutrients in one fully water-soluble powder.\u003c\/p\u003e\n\n    \u003cdiv class=\"drf-stats\"\u003e\n      \u003cdiv class=\"drf-stat\"\u003e\n\u003cspan class=\"drf-stat-number\"\u003e10%\u003c\/span\u003e\u003cspan class=\"drf-stat-label\"\u003eCalcium (Ca)\u003c\/span\u003e\n\u003c\/div\u003e\n      \u003cdiv class=\"drf-stat\"\u003e\n\u003cspan class=\"drf-stat-number\"\u003e8%\u003c\/span\u003e\u003cspan class=\"drf-stat-label\"\u003eNitrogen (N)\u003c\/span\u003e\n\u003c\/div\u003e\n      \u003cdiv class=\"drf-stat\"\u003e\n\u003cspan class=\"drf-stat-number\"\u003e100%\u003c\/span\u003e\u003cspan class=\"drf-stat-label\"\u003eWater Soluble\u003c\/span\u003e\n\u003c\/div\u003e\n      \u003cdiv class=\"drf-stat\"\u003e\n\u003cspan class=\"drf-stat-number\"\u003eSoy\u003c\/span\u003e\u003cspan class=\"drf-stat-label\"\u003ePlant-Based Source\u003c\/span\u003e\n\u003c\/div\u003e\n    \u003c\/div\u003e\n\n    \u003ch3\u003eWhat Cal-Mino is used for in the garden\u003c\/h3\u003e\n    \u003cul class=\"drf-uses\"\u003e\n      \u003cli\u003e\n\u003cstrong\u003ePreventing blossom end rot\u003c\/strong\u003e — the most common calcium-related disorder in tomatoes, peppers, courgettes, and aubergines;

Once deposited in a cell wall or vacuole, it is fixed in place. Unlike nitrogen, potassium, or magnesium — which can be remobilised from old tissue to new growth — calcium travels only upward through the xylem, pulled by transpiration. It cannot enter the phloem. It cannot move from leaves to fruit. It cannot redistribute to where demand is greatest.\u003c\/p\u003e\n    \u003cp\u003eThis is why blossom end rot occurs even in calcium-rich soil. The fruit is growing faster than the xylem stream can supply it. Irregular watering, high temperatures, and rapid growth all worsen the imbalance. Adding more calcium to the soil does not solve the problem if the transport system is the bottleneck.\u003c\/p\u003e\n\n    \u003chr class=\"drf-sep\"\u003e\n\n    \u003cdiv class=\"drf-mech\"\u003e\n\u003cspan class=\"drf-mech-num\"\u003e01\u003c\/span\u003e\u003ch4\u003eAmino Acid Chelation \u0026amp; Foliar Uptake\u003c\/h4\u003e\n\u003cp\u003eThe leaf cuticle is a waxy barrier evolved to prevent water loss. Charged mineral ions like Ca²⁺ struggle to cross it. When calcium is chelated with amino acids, the resulting molecule is small, uncharged, and organic — properties that dramatically improve cuticular penetration. Research consistently demonstrates 2–5 times greater foliar absorption rates for amino acid chelated minerals compared to inorganic salts. This makes foliar spraying a genuinely effective calcium delivery method rather than a token gesture.\u003c\/p\u003e\n\u003c\/div\u003e\n\n    \u003cdiv class=\"drf-mech\"\u003e\n\u003cspan class=\"drf-mech-num\"\u003e02\u003c\/span\u003e\u003ch4\u003eBeyond the Xylem — Amino Acid Transport\u003c\/h4\u003e\n\u003cp\u003eFree Ca²⁺ ions are restricted to xylem transport. Amino acid chelated calcium may access additional transport pathways because the plant recognises the chelate as a nitrogen-containing organic molecule. Amino acid and peptide transporters exist in both xylem and phloem tissues. While calcium remains inherently difficult to redistribute once deposited, delivering it as an amino acid chelate to the leaf surface nearest the developing fruit gives it the shortest possible distance to travel — bypassing the root-to-fruit xylem bottleneck entirely.\u003c\/p\u003e\n\u003c\/div\u003e\n\n    \u003cdiv class=\"drf-mech\"\u003e\n\u003cspan class=\"drf-mech-num\"\u003e03\u003c\/span\u003e\u003ch4\u003eCalcium in Cell Wall Structure\u003c\/h4\u003e\n\u003cp\u003eCalcium cross-links pectin chains in the middle lamella — the cement between plant cells.
