Functional modulesRFe-01 · Real Iron — concentrated nettleOrigin: Yolia's safe educational catalogExact route: /biblioteca?ruta=modulos/rfe-01 FULL PROFILEThe 17 points of this moduleEach section opens separately — tap the title to expand it. 1. Code, name, species RFe-01 — Real Iron. Rosa spp. This module belongs to the Rose Catalog family, within the Base Nutrient / Life Cycle functional class, and is prepared as a ferment within Yolia's complete catalog of documented safe modules for the species in this system. 2. Application method Root watering. This method was chosen because it gradually distributes the input toward the area where the plant can absorb it, being consistent with the rest of the modules in the Rose Catalog family documented in this catalog. Consulted by the engine when building a formula for the case. 3. What the real problem/need is Iron is essential for making chlorophyll, but unlike nitrogen or magnesium (which also give green color), iron deficiency looks different and very characteristic: **yellow leaves with veins still green** (iron chlorosis). 4. Exact function Correct or prevent iron chlorosis by providing real, bioavailable iron. This specific function is what Yolia's engine evaluates when considering whether the RFe-01 module is relevant for a case within the Rose Catalog family of the complete catalog of modules. 5. Chemistry Nettle (*Urtica dioica*) is one of the common plants with the highest documented actual bioavailable iron content, along with other trace minerals. The iron it provides is in organic form (naturally chelated by the plant's own compounds). 6. Preparation method [Ferment], using fresh nettle (the leaves are cut with gloves, since fresh nettle stings to the touch due to its stinging trichomes — that effect disappears completely after fermentation). As a ferment, this preparation process is what determines the final availability of the compounds. 7. Mechanism Absorbed iron is an essential component of the enzymes that manufacture chlorophyll — without sufficient iron, those enzymes don't work, even if there is plenty of nitrogen and magnesium. This is the mechanism the Yolia engine documents when evaluating the actual function of the RFe-01 module within the class. 8. Stage of use Vegetative, and any time chlorosis appears in new leaves. This stage was chosen because it's when the plant can best take advantage of this specific input, within the general logic of the Rose Catalog family documented in Yolia's complete catalog. 9. Frequency Every 10-14 days, or upon detecting symptoms. This frequency aims to sustain the effect without saturating the plant, taking into account the stability and preparation method specific to this ferment module within the Rose Catalog family. Consulted by the engine when building a formula for the case. 10. Stability 5-7 days refrigerated. This stability time reflects how long the preparation retains its activity before losing effectiveness, being relevant for planning the application frequency of this ferment module. Documented within Yolia's complete catalog of safe modules. 11. Concentration Low-moderate. This concentration level is adjusted according to the sensitivity of the stage of use and the specific function of this module within the Base Nutrient / Life Cycle functional class of Yolia's complete catalog. Part of the set of technical sheets in Yolia's complete catalog. 12. How the engine processes it Capacidad `vegetal_verde_mineral`. Prioridad alta si el usuario reporta específicamente "hoja amarilla con venas verdes" en los síntomas del caso. Así es como el motor de Yolia evalúa la inclusión de este módulo RFe-01 dentro de una fórmula, considerando su función específica dentro de la familia. 13. Compatibility Compatible with everything; it does not compete with other nutrients over the same mechanism. This compatibility is reviewed within the Compatibility Engine before including this module together with other elements of the Rose Catalog family in the same formula generated for the case. 14. What to expect New leaf that emerges uniformly green, without the pattern of green veins on a yellow background. This expected signal helps verify whether the RFe-01 module is functioning as documented within the Base Nutrient / Life Cycle functional class of Yolia's complete catalog of safe modules. 15. If misused Excess iron is rarely toxic to the plant, but it can unbalance manganese absorption. This is the risk that the Risk Engine considers before approving a higher concentration or frequency for this ferment module within the Rose Catalog family of the complete catalog. 16. Special precaution None critical for rosebush. This precaution is part of the safety documentation for this RFe-01 module, reviewed within Yolia's complete catalog of documented safe modules for cultivation. Documented within Yolia's complete catalog of safe modules. 17. Related to [RMg-01] Green Magnesium — [Chlorophyll and photosynthesis] — [Chlorosis: differential diagnosis] These relationships help understand how this RFe-01 module connects with other elements of the Rose Catalog family and the Base Nutrient / Life Cycle functional class within the complete catalog.
