Functional modulesRCa-01 · Structural Calcium — toasted eggshellOrigin: Yolia Secure Educational CatalogExact route: /library?path=modules/rca-01 COMPLETE SHEETThe 17 points of this moduleEach section opens separately — tap the title to expand. 1. Code, name, species RCa-01 — Structural Calcium. Rosa spp. This module belongs to the Pink Catalog family, within the Base Nutrient / Life Cycle functional class, and is prepared as a ferment within the complete catalog of safe modules documented by Yolia for the species of this system. 2. Application method Root irrigation (to the ground). This method was chosen because it distributes the contribution gradually to the area where the plant can absorb it, being consistent with the rest of the modules of the Pink Catalog family documented in this catalog. Documented within the complete catalog. 3. What is the real problem/need Calcium does not move easily within the plant once absorbed (unlike nitrogen, which the plant can recycle from old to new leaf). That's why a calcium deficiency is first noticed in NEWER tissue: petals that look brittle or have misshapen edges. 4. Exact function Provide bioavailable calcium to strengthen cell wall in actively growing tissue — petal, new shoot, root tip. This specific function is what the Yolia engine evaluates when considering whether the RCa-01 module is relevant to a case within the Pink Catalog family. 5. Chemistry The calcium carbonate in the eggshell, when toasted and ground fine, becomes more reactive and soluble in the fermentation process. The released calcium ion (Ca²⁺) integrates into the cell wall forming calcium pectate — a compound that literally cross-links the pectin fibers. 6. Preparation mode [Ferment]. The peel is roasted first (this helps it grind finer and release calcium easier during fermentation) and is ground before combining with water. As a ferment, this preparation process is what determines the final availability of the active compounds before. 7. Mechanism The root absorbs dissolved calcium via water flow (transpiration) — so calcium reaches tissues with little active transpiration less (like an already formed petal) and better to actively growing tissue with high transpiration. This mechanism is what the Yolia engine documents when evaluating. 8. Use stage Continuous, with emphasis on pre-flowering (when the new petals that will need that structure are forming). This stage was chosen because it is when the plant can best take advantage of this specific contribution, within the general logic of the Catalog Rosa family documented in the catalog. 9. Frequency Every 10-14 days. This frequency seeks to sustain the effect without saturating the plant, considering the stability and preparation mode of this ferment module within the Rosa Catalog family. Documented within the complete catalog of Yolia secure modules. 10. Stability 5-7 days refrigerated. This stability time reflects how much the preparation retains its activity before losing effectiveness, being relevant to plan the frequency of application of this ferment module. Part of the set of technical sheets of the complete Yolia catalog. 11. Concentration Low-moderate; The exact proportion is calibrated when purchasing. This concentration level is adjusted according to the sensitivity of the use stage and the specific function of this module within the Base Nutrient / Life Cycle functional class of the complete Yolia catalog. 12. How the engine processes it Capacity `calcium_structure`. High priority when the case reports brittle petals or deformation of the new shoot. This is how the Yolia engine evaluates the inclusion of this RCa-01 module within a formula, considering its specific function within the Pink Catalog family of the catalog. 13. Compatibility Complement directly with [RSi-01] silica — both reinforce structure through different pathways. This compatibility is reviewed within the Compatibility Engine before including this module along with other elements of the Pink Catalog family in the same formula generated for the case. 14. What to expect Petals with a firmer texture, new shoots that do not dry at the tip. This expected signal helps verify if the RCa-01 module is functioning as documented within the Base Nutrient/Lifecycle functional class of Yolia's complete catalog of secure modules. 15. If used wrong Excess calcium can block the absorption of other minerals (magnesium, potassium) by competition — it is not directly toxic, but it unbalances other nutrients. This risk is what the Risk Engine considers before approving a higher concentration or frequency for this ferment module. 16. Special caution No criticism for rosal. This precaution is part of the safety documentation of this RCa-01 module, reviewed within the complete catalog of safe modules documented by Yolia for cultivation. Part of the set of technical sheets of the complete Yolia catalog. 17. Related to [RSi-01] Structural Reinforcement Silica — [Plant Cell Wall] — [R-P05] Petal Density These relationships help understand how this RCa-01 module connects with other elements of the Pink Catalog family and the Base Nutrient / Life Cycle functional class within the complete catalog.
