Calculation of Safe Storage Time
Centaur’s software incorporates predictive models that assess grain deterioration and estimate safe storage time based on three key quality indicators: dry matter loss, mold development risk, and germination capacity reduction (Figure 1).
When Safe Storage Time metrics indicate low values, the grain is approaching critical condition. Users should take grain samples and/or implement one of the remediation strategies outlined in the Aeration and Coring sections.
Figure 1. Centaur Internet-of-Crops® platform calculates grain safe storage time using three quality criteria:
Dry Matter Loss (DML): This metric evaluates safe storage time based on dry matter loss caused by respiration. During respiration, carbohydrates are oxidized (combusted), producing carbon dioxide, water vapor, and energy, which results in measurable dry matter loss.
Visible Mould (VM): This metric assesses safe storage time based on the potential appearance of visible mold. Visible mold indicates the presence of microorganisms that cause grain spoilage.
Germination Capacity Loss (GRM – when supported for the crop): This metric calculates safe storage time based on germination capacity, defined as the emergence of the first signs of outgrowth—specifically, the visible protrusion of the radicle. Quality deterioration is indicated by a reduction in germination capacity, with a threshold set at 1%.
