Soil degredation

result of human activities such as intensive agricultural practices on susceptible lands where land is used beyond its inherent capacity

Examples of intensice agricultural processes

tillage, machinery, inorganic fertilizers, no cover-crops, mono-cropping

Ecosystem goods and services impacted by soil erosion

provisioning of material goods and services, regulation of ecosystem processes, non-material services

soil erosion

soil organic metter decline

soil contamination

loss of soil biodiversity

soil surface sealing

soil compaction

salinization

landslides

desertification

soil erosion by water

prevented with contour farming

soil erosion by wind

soil erosion by tillage

soil erosion through co-extraction with crops, vehicles, and machinery

loss of soil depth

three ways erosion affects plant growth principally

loss of soil nutrients and carbon

changes in soil health

depositional effects
