Using Noncontributing Area to Assess Landform Development in the Central Lowlands of North America

Precision land surface analysis and machine learning for enhanced soil maps: Strengthening the foundation for agroecosystems research

“…The study area is depicted by an updated Iowa physiographic sub-regions map based on soil series associations and topography to delineate similar soil-forming regions for sampling and modeling purposes (McDanel, 2019). The area of interest encompasses counties that intersect the boundary of the Des Moines Lobe (Dows formation) and the boundary of another Wisconsinaged till (Sheldon Creek formation) proposed by Kerr (2018).…”
