Where is the field?

Type a ZIP code or a city. We'll pull your USDA hardiness zone and use it to tune species fit, planting windows, frost-kill timing, and the nitrogen plan.

Pick a location to unlock the rest of the field plan.

The ZIP or city sets hardiness, frost, and water context for every later recommendation.

Built on USDA PHZM 2023 for winter hardiness, 15-year Open-Meteo ERA5 frost and water-balance normals, GeoNames postal data (CC-BY 4.0), SARE's Managing Cover Crops Profitably, Penn State and OSU N-credit calculators, Rodale Institute termination guidance, NRCS cover crop charts, and land-grant establishment/grazing/dryland water guidance. All recommendations are planning estimates — verify with your local extension service or NRCS before acting. Questions? Ask a soil-health expert.
