Any set of measures which control or prevent soil erosion, or maintain soil fertility Soil Conservation Soil Conservation Aims Soil Conservation Aims  Conclusion Soil degradation and remediation are essential topics for the preservation of the environment and the health of our planet. As the human population grows, the need for food, water, and energy increases, while at the same time, our planet's resources are being depleted. Soil degradation and remediation can help us improve our environment while also ensuring that we have enough food, water, and energy for future generations.
