What does SOC stand for?

INTRODUCTION Soil organic matter and soil organic carbon (SOC) sequestered in it are major factors in soil formation, development, and functioning (Van Cleve & Powers 1995; Paustian et al.

Soil scientists mostly from North America but also around the world discuss such topics as testing the introductory carbon balance model on soil organic carbon change in Canadian agro-ecosystems, soil carbon sequestration in different ecoregions of Mexico, the effects on soil organic carbon of managing dryland cropping systems in the US Great Plains, sequestration by biochemically recalcitrant biomacromolecules, linking soil organic carbon and environmental quality through conservation tillage and residue management, carbon dynamics in urban soils, and priorities in soil carbon research in response to climate change.

Erosion is affected by farming practices, soil types, and weather, and Wilhelm says it's "a very good question" whether it's possible to predict what level of stover removal will hold soil organic carbon loss below tolerable levels.

No-till with cover crop agriculture can create a carbon sink, resulting in higher soil organic carbon levels than those in unmanaged forests and grasslands.

4) To estimate organic matter, scientists usually multiply the (more easily determined) soil organic carbon value by a conversion factor of 1.

From a management perspective, soil carbon reserves should be protected and enhanced by minimising vegetation removal and cultivation, and by building up soil organic carbon levels with deep-rooted plant species.
