Study Notes
Soil and Water Conservation
- Soil and water conservation involves controlling erosion and maintaining soil fertility while wisely using water to meet essential demands.
Importance of Soil and Water Conservation
- Soil and water conservation is crucial, especially in the current situation where there is increased pressure on soil and water resources to fulfill human needs and ensure food security.
Causes of Soil Degradation
- Livestock overgrazing, deforestation, and cropland agriculture are the main causes of soil degradation.
Functions of Water
- Agriculture is the largest use of withdrawn water, with 13% being consumptive use.
- Industrial use of water can be the largest use in highly industrialized nations, with both consumptive and recycled water being used.
- Municipal use of water is also consumptive and recycled back to surface waters.
- Wildlife and recreation are also important uses of water, with economically important utilization of stored water.
Pressure on Soil and Water Resources
- Increasing population and standards of living lead to:
- Deforestation and urbanization, resulting in land degradation.
- Irrigation of deserts, increasing water demand.
- Extensive plowing and fertilizer use, enhancing land degradation.
Soil Conservation
- Soil conservation means maintaining the functions of the soil to sustain plant growth.
- It involves managing soil erosion, reducing sedimentation, and exploiting new opportunities.
Importance of Soil
- Soils are critical to the human condition, providing for food, fiber, fuel, and feed production.
- Soils have various urban uses, regulate water flow, serve as a filter for water, and regulate air quality.
- Soils are involved in regulating the terrestrial water cycle and serve as a sink for CO2 and CH4.
Impacts of Soil Management
- Soil management affects water availability, water quality, and air quality.
- It influences runoff, drainage, evapotranspiration, and the terrestrial water cycle.
Test your knowledge on controlling erosion, maintaining soil fertility, and wisely using water to meet essential demands. Explore practices like managing soil erosion, reducing negative impacts, and protecting soil and water from contaminants.
