Influences of nitrogen on carbon dynamics in forest soil and density fractions

Creator:

Swanston, Christopher W.

Abstract:

Application of N fertilizer is a common forest management practice in the Pacific Northwest, yet the long-term influence of fertilization on forest soil properties is not well known. Although elevated N often increases mineralization of C and N from labile organic matter, negative effects have been documented in recalcitrant organic...

Dynamics of water-soluble carbon in forest soils of contrasting fertility

Creator:

Wagai, Rota

Abstract:

Most soil organic C is in a stable form, associated with clay minerals in the upper soil profile. Upon environmental and land-use changes, stable soil C is subject to losses, which influence the global C cycle and the productivity of terrestrial ecosystems. However, mechanisms controlling soil C destabilization are not...

Characteristics of dissolved organic matter (DOM) and its stabilization in forest soil

Creator:

Yano, Yuriko

Abstract:

Dissolved organic matter (DOM) plays an important role in transport of C and essential nutrients such as N, P and S. DOM is also critical for the formation of soil organic matter (SOM), which is the largest terrestrial C pool. Nonetheless, we lack a basic understanding of what controls immobilization...
