The Earth's land surface is dominated by sloping landscapes. Every year, soil erosion laterally distributes on the order of 75 Gt of topsoil (Berhe et al. 2007). The coupled biogeochemical cycles of ...

Iron isotope fractionation has emerged as a critical tracer for deciphering the complex biogeochemical cycling of iron in soils. This process, whereby natural variations in the relative abundance of ...

Earth’s Mantle Nitrogen Content Is Comparable To That Found In Its Nitrogen-Rich Atmosphere. Mantle Nitrogen has been proposed to be primordial or sourced by later subduction, yet its origin has not ...

Soil erosion is widely known for degrading land and reducing agricultural productivity. But new research shows it may also ...
