Track cumulative GDD from daily temperatures and estimate days to maturity for your crop.
Selecting a crop auto-fills base temperature and GDD to maturity
Growth stops below this temperature
Total GDD needed from planting to maturity (auto-filled from crop selection)
Enter min and max temperatures for each day. Corn automatically uses a 30°F (86) Tmax cap (modified GDD).
Enter daily temperatures above to calculate cumulative GDD and track crop maturity progress.
Score your 5-crop rotation for disease break, nitrogen fixation benefit, and weed diversity using family-based analysis.
Estimate theoretical crop yield from plant population, fruit count, and average weight — outputs tonnes/ha, kg/ha, bu/acre, and lb/acre.
Calculate product per tank load and total product needed for foliar sprays, growth regulators, and fertilizer applications.
