Competency Area 5: Soil conservation AEM

Summary

• Soil erosion, or the loss of soil due to both human and natural causes, is a major problem.  Erosion varies depending on the type of soil, rainfall, soil erodibility, crops grown and other management factors, the slope, and any erosion control practices.
• Soil conservation practices seek to retain soil by catching runoff water and filtering out the soil.  Tillage practices can be altered to reduce the stirring up of soil, thus reducing potential runoff.
• Different cropping systems focus on different crops, have different goals, and thus have different issues like compaction, runoff, erosion, etc.

Conservation practices: terraces, pond, conservation tillage, and others
