Relationships between soil properties and soil degradation.6 typical types of soil erosion, their factors, processes and conservation practices for each type.Soil erosion, soil quality and food security relationship. Case studies will also be provided to help you to understand the adverse effects and necessarily to protect soils
So conserve soil is necessary. Through this class, you will get the knowledge of what Chairman Xi said "Lucid waters and lush mountains are invaluable assets”.
