Soil is a non-renewable resource that is important for maintaining food security and a sustainable future. Here are some ways to save soil: 

Plant trees: Trees bind the soil to the ground and prevent erosion from wind and water. Planting trees in semi-arid areas can also attract rainfall. 

Use terrace farming: Cut steps into hillsides to absorb water runoff and prevent topsoil from being washed away. 

Use conservation tillage: Don't till the soil, which helps retain moisture. 

Use cover crops: Plant secondary species between cash crops to promote soil conservation. 

Use crop rotation: Diverse root systems improve soil structure, and legumes add nitrogen to the land. 

Use strip cropping: Divide large fields into strips with grass growing between crops to break up wind force. 

Use contour plowing: Slow water runoff. 

Use windbreaks: Reduce wind erosion. 

Soil conservation is important for biodiversity as well, as healthy soil supports many life forms
