A browser-based irrigation scheduling tool for Kansas center pivot farmers, built on the FAO-56 soil water balance model.
- Fetches daily weather data from the Kansas Mesonet for the selected station
- Estimates reference evapotranspiration (ETo) using a calibrated OLS model (solar radiation, VPD, wind speed) with Hargreaves as fallback
- Simulates daily soil water balance from planting to harvest using crop-specific Kc curves, SCS curve number runoff, and dynamic root growth
- Schedules center pivot irrigation based on Management Allowed Depletion (MAD) or refill-to-FC strategies
- Provides an AI summary of the season outlook via Claude Haiku 4.5 (DigitalOcean serverless proxy)
Corn, Soybean, Grain Sorghum, Winter Wheat, Sunflower — with Kansas-specific planting dates and FAO-56 Kc parameters.
