Abstract
Sodic soils have poor plant growth and thus carbon (C) inputs are reduced compared to nonsodic soils. Soil samples were taken from three sodic zones: 1) patch-center, 2) transition, and 3) adjacent at three sites located in southwest North Dakota. Soil sodium adsorption ratio (SAR) was highest at patch centers (mean of three sites, SAR = 306), and then declined to transition (SAR = 29.5) and was lowest at adjacent (SAR = 9.21). The labile C pool showed an inverse relationship with SAR. In the northern Great Plains, C dynamics is highly variable and can be strongly controlled by the development and persistence of sodic soils.
