Great Plains: This vast, flat region covers much of the central part of the country, extending from Canada down to Texas. It's known for its fertile soils and agricultural productivity. Appalachian Mountains: These mountains run along the eastern part of the country, from Alabama to Maine. Th...
Attaining high crop yields and increasing carbon storage in agricultural soils, while avoiding negative environmental impacts on water quality, soil erosion, and biodiversity, requires accurate and precise management of crop inputs and management practic
TheNational Geologic Map Database, run by the United States Geological Survey, catalogues maps and geologic names, and also describes what mapping is currently underway. Clicking on the “Geoscience Map Catalog” is a portal to info sections describing over 75,000 maps of United States geology fr...
Combined with US Geological Survey LiDAR data, we computed site index and generated wall-to-wall productivity maps for planted Pinus taeda stands in the southeastern US, as well as point-based site index estimates for the FIA dataset. We modeled site index using a random forest algorithm ...
Following this, there was a shift in research focus to organic carbon in soils. As the industrial sector continues to expand, soil degradation has emerged as a significant global sustainability concern. Human activities, including land use change, have a detrimental impact on soil quality and the...
