Seed Germination Rate & Harvest Planner
Professional agricultural tool. Calculate germination rates, adjust seeding density, and estimate harvest dates for 50+ crop types.
About
In commercial agriculture and precision gardening, seed viability determines the difference between profit and loss. Relying on old seed stock without testing leads to inconsistent canopy cover and yield reduction. This tool serves a dual purpose: it calculates the precise Germination Rate of your current stock and provides a corrected Seeding Density Adjustment.
Furthermore, it integrates a Harvest Projection engine. By selecting a specific crop from our database of over 50 varieties, the system estimates the Days to Maturity (DTM) based on optimal temperature ranges, ensuring your planting schedule aligns with seasonal windows.
Formulas
We utilize a Weighted Mean algorithm for multi-batch testing to ensure small sample sizes do not skew the result:
The Seeding Correction Factor (k) is derived from the inverse of the success probability:
