The impact of agricultural soil erosion on biogeochemical cycling [PDF]

open access: yes, 2010
Soils are the main terrestrial reservoir of nutrients, such as nitrogen and phosphorus, and of organic carbon. Synthesizing earlier studies, we find that the mobilization and deposition of agricultural soils can significantly alter nutrient and carbon ...
