Field notes
The page divides its tools by farm task rather than presenting one general-purpose calculator. Descriptions specify inputs such as soil-test values, grain-cart weight and moisture, and planting dates, with outputs including nutrient comparisons, standardized yield, or heat-risk timing. The herbicide builder says it draws on university ratings; the extracted homepage does not show the underlying ratings or tool interfaces. The site credits Steven McKechnie and links to GitHub.
