Solution(By Examveda Team)

Soil Conservation is protection against loss of soil.
Soil conservation is the prevention of loss of the topmost layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination.
Techniques for improved soil conservation include crop rotation, cover crops, conservation tillage and planted windbreaks, which affect both erosion and fertility.
