Map of saturated hydraulic conductivity at a 5-cm depth for the contiguous United States. This map shows large-scale variation with high conductivities on coarse materials (orange-red, such as Florida, mountains, glacial sediments) and low conductivities on the fine sediments in the U.S. interior (blue). Actual map holds 49,810 × 31,390 pixels (West–East × North–South) at 100-m resolution. Image by Marcel G. Schapp, Yonggen Zhang, and Craig Rasmussen.

Soybean growth, development, and subsequent yield can be impacted by soil quality. This photo highlights the fragile period after germination to help illustrate this relationship. Photo by Lindsay Chamberlain Malone.

Soybean yield is positively linked to organic matter, but planting date remains more influential

Site-specific management zones of actual evapotranspiration and turfgrass quality at Eagle Lake Golf Course in Roy, UT and histograms of the four natural break classes (1-4) of estimated TQ. Blue lines identify the fairway, greens, and tee boundaries and red dots identify sprinkler heads. Image by Karem Meza.

Monthly trends in grazing land condition ratings (measured as the CCIndex) over the 1995–2022 period. Browns represent declining grazing land conditions while greens represent improving conditions. Hatching is statistical significance at the 95% confidence level. Image adapted from Bundy et al. (2025).

Image of web interface looking at Global Historical Climatology Network daily (GHCNd) data with example downloading a small region of data in southeast Minnesota. In the map, a user can define a bounding box (blue-square). Then in the application programming interface (API) call, the user can define the climate variable, the dates for which the data should be gathered and the type of aggregation that is requested. Image from Gall et al. (2024).
