Hay Dry-Matter and Safe-Storage Weight

The weight restated at a target moisture for an equal-basis comparison, and a heating/mold risk flag where the measured moisture is above the safe-storage ceiling (default 18% large / 20% small, editable). The producer and local extension guidance govern.

dry_matter = bale_weight x (1 - moisture/100); weight_at_target = dry_matter / (1 - target_moisture/100); flag set where moisture > safe_threshold (default 18% large / 20% small).

First-principles dry-matter mass balance with USDA NRCS / land-grant extension safe-storage guidance (by name); no edition cycle.

The mass balance is public; the safe-storage thresholds are editable. The producer and local extension guidance govern.

Estimate. AHJ and licensed professional govern.

• Safe ceiling default 18% for large packages, 20% for small squares, both editable; wetter hay heats and moldsUSDA NRCS / extension
• Combustion risk very wet, tightly stacked hay can heat enough to spontaneously combust; monitor and do not store tight above the ceilingextension guidance
