Code, name, species RPH-01 — Natural Acidifier. Rosa spp. This module belongs to the Rose Catalog family, within the Microbiology / Regulation functional class, and is prepared as a macerate 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 When the substrate has too alkaline a pH (above roughly 7.5), several essential nutrients — especially iron and manganese — become chemically insoluble and get trapped in the soil, inaccessible to the root, even though they are physically present. 4. Exact function Lower the substrate's pH to a range where micronutrients become available for absorption again. This specific function is what the Yolia engine evaluates when considering whether the RPH-01 module is relevant for a case within the Rose Catalog family of the complete module catalog. 5. Chemistry The acetic acid in vinegar reacts with the carbonates and bicarbonates in the soil (responsible for alkalinity), partially neutralizing them and gradually lowering the substrate's measurable pH with repeated applications. This composition is the documented chemical basis of the RPH-01 module. 6. Preparation method [Macerate] simple — direct dilution, does not require extraction of plant material. As a macerate, this preparation process is what determines the final availability of the active compounds before being applied within the Rose Catalog family's program. 7. Mechanism Direct chemical effect on the substrate, not on the plant — the pH change is what indirectly "releases" nutrients already present so the root can absorb them. This is the mechanism that the Yolia engine documents when evaluating the actual function of module RPH-01 within the functional class. 8. Stage of use When an alkaline substrate pH is confirmed or suspected (common in areas with hard/alkaline irrigation water). This stage was chosen because it is 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 Gradual repeated applications — changing soil pH is not instantaneous, it requires consistency over weeks. This frequency aims to sustain the effect without oversaturating the plant, considering the stability and preparation method specific to this macerate module within the Catalog family. 10. Stability Very stable, weeks if kept well covered (diluted vinegar doesn't degrade the way other modules' volatile compounds do). This stability time reflects how long the preparation retains its activity before losing effectiveness, which is relevant for planning application frequency. 11. Concentration Low, diluted — pH changes must be gradual so as not to stress the root. This concentration level is adjusted according to the sensitivity of the stage of use and the specific function of this module within the Microbiology / Regulation functional class of Yolia's complete catalog. 12. How the engine processes it Capacidad `ph_estabilizacion`. El motor lo activa cuando el caso reporta agua de riego alcalina o síntomas de clorosis sin causa de deficiencia directa confirmada. Así es como el motor de Yolia evalúa la inclusión de este módulo RPH-01 dentro de una fórmula. 13. Compatibility It is recommended before applying iron modules (RFe-01) in alkaline soils, so that the iron applied afterward actually becomes available. This compatibility is checked within the Compatibility Engine before including this module together with other elements of the Rose Catalog family in the same. 14. What to expect Gradual correction of chlorosis in cases where the cause was pH, not a genuine deficiency — a process of weeks. This expected signal helps verify whether module RPH-01 is working as documented within the Microbiology / Regulation functional class of the complete catalog of safe modules. 15. If misused Lowering the pH too quickly or too much can make other nutrients toxic through over-availability. This is the risk that the Risk Engine considers before approving a higher concentration or frequency for this macerate module within the Rose Catalog family of the complete catalog. 16. Special precaution None critical for rose bush, but requires patience — it is not an immediate correction. This precaution is part of the safety documentation for this RPH-01 module, reviewed within Yolia's complete catalog of documented safe modules for cultivation. 17. Related to [RPH-02] Natural Alkalizer (opposite effect) — [RFe-01] Real Iron — [Soil pH and nutrient availability] These relationships help understand how this module RPH-01 connects with other elements from the Rose Catalog family and the Microbiology / Regulation functional class.
