Field notes
The lookup is organized by state and NOAA station, with spring and autumn probabilities at 10%, 50%, and 90%; the site explains that these are risk estimates, not deadlines, and distinguishes 36°F, 32°F, and 28°F thresholds. Separate planning pages cover nine crop groups, fall sowing with an optional harvest window and UNL Fall Factor, and germination temperatures for 27 vegetables. Guidance pages compare extension recommendations, including a noted disagreement about cabbage classification.
