Decay calculator for Poaceae seeds at room temp
Treat Grass Seeds Like Assets
Poaceae seeds (e.g. Corn, Wheat, Rice) depreciate in storage. Use this scientific calculator to predict when your grass seed stock will become unviable at room temperature.
Depreciation Insight
Grass seeds stored in a shed have an estimated half-life of 3.5 years.

Why Calculate Poaceae Viability?
Starchy seeds that are moderately long-lived but sensitive to humidity. Members of the Poaceae family, such as maize, wheat, and rice, possess a starchy endosperm that provides essential energy for germination but also makes them hygroscopic. This means they readily absorb moisture from the air, accelerating metabolic degradation if storage conditions are not optimized. Like all seeds, they follow a negative sigmoid curve of decay.
Using the Ellis-Roberts equation with constants specific to Poaceae, we can predict that their half-life is approximately 3.5 years under these conditions.
Proper storage management is critical for Poaceae seeds. By tracking the depreciation schedule, you can anticipate when germination rates will fall below acceptable thresholds (usually 85% for commercial standards or 50% for conservation). This calculator helps you schedule regeneration cycles effectively, ensuring you don't lose valuable genetic resources.
