17 datasets
Agriculture datasets range from field measurements to national statistics. The list covers gridded crop yields (the Global Dataset of Historical Yield), county-level corn, soybean and wheat yields from USDA NASS, the USDA PLANTS checklist, growing degree days by US ZIP code, farmland prices across countries and a hyperspectral soil moisture benchmark. Food composition sits here too, with USDA FoodData Central and the crowdsourced Open Food Facts product database.
Licences vary more than the subject suggests. Open Food Facts uses the ODbL, which asks you to share derived databases under the same terms, while many of the smaller sets here are CC BY and only need attribution. USDA data is US federal work and generally free to reuse. Check the unit and resolution before joining sources: grid cells, counties and ZIP code areas rarely line up, and crop yields are reported per year while degree days update daily.
Agricultural land prices in 37 countries, each from that country's own statistical office, converted to one currency at a single European Central Bank reference rate and ranked. Every row carries its basis, year and source, because the figures are not strictly comparable. Available as CSV and JSON…
