Carbon Sequestration in crops and soil organic carbon

Carbon Sequestration in crops and soil organic carbon. Xavier Driver. Drylands in the northern Great Plains have lost 30 to 50% of their original soil organic carbon levels during the last 50 to 100 years due to continuous cultivation and summer fallowing (Upendra M. Sainju et al., 2005).

Intensive tillage, soil erosion and insufficient added residues

Intensive tillage, soil erosion and insufficient added residues. Aggregates break down. Soil organic matter decreased. Increased erosion by wind and water. Surface becomes compacted, crust forms. Less soil water storage, less diversity of soil organism, fewer nutrients for plants.
