Resources
Datasets, extension, code, and tools — curated next to the research.
OpenAgData indexes the research. This page indexes the things that go with it — open datasets you can query, extension publications you can cite, models and code you can run, and decision-support tools built on top of the literature. Curated, not exhaustive.
Open, curated US agricultural datasets you can query directly.
USDA National Agricultural Statistics Service
USDA NASS Quick Stats
Searchable API for US crop, livestock, demographic, and economic statistics — county, state, ASD, and national resolution.
USDA-ARS LTAR
Long-Term Agroecosystem Research (LTAR) Network
18 research sites collecting harmonized long-term data on cropping systems, livestock, and ecosystem services across the US.
USDA-ARS
GRACEnet — Greenhouse gas Reduction through Agricultural Carbon Enhancement
Standardized field measurements of soil carbon and greenhouse gas fluxes across US agricultural sites.
AmeriFlux / DOE
AmeriFlux Network
Eddy covariance tower network measuring CO₂, water, and energy flux across hundreds of North American ecosystems, including croplands.
Battelle / NSF
NEON — National Ecological Observatory Network

SSURGO — Soil Survey Geographic Database
The most detailed soil mapping product for the US — soil polygons with linked property and interpretation tables.
USDA NASS
CropScape / Cropland Data Layer
Annual 30-meter raster of crop cover for the conterminous US — the standard reference for what's growing where.
Oregon State University PRISM Group
PRISM Climate Data
Gridded estimates of precipitation, temperature, and other climate variables at 4-km and 800-m resolution across the US.
OpenET Consortium
OpenET — Satellite ET Data
Field-scale evapotranspiration estimates for the western US, served as a free, satellite-based water budget tool.
