Gold is less valuable than Topsoil. Yet Gold is now valued more than Topsoil, and Forests. I'd rather ask "How does selective logging protect Forests?"
The loss of topsoil
how does contour plowing help conserve topsoil
Topsoil.
Contour plowing helps preserve topsoil by following the natural contours of the land, which reduces water runoff and soil erosion. By plowing along the contours, water is able to infiltrate the soil rather than running off and carrying away topsoil. This practice helps retain nutrients and organic matter in the soil, promoting healthier and more productive farmland.
Trees planted close together are often used to block wind and in doing so, prevent topsoil from being blown away.
1) Loss of habitats for native species 2) Land is harmed because topsoil cannot be held down, leading to erosion 3) Clear cutting is often performed in places where the land is unsuitable for monoculture agriculture, like in the tropical rainforests, so it probably won't be helpful for production for more than a short period of time.
Topsoil naturally builds up over long periods, but can be blown or washed away. Areas with deeper topsoil are not subject to these types of erosion, and may have a very long history of vegetation (such as centuries of forest cover) which has caused the buildup, or be in an area that catches a lot of wind or water borne soil.
Some good brands of topsoil include but are not limited to Miracle Grow topsoil, Black Magic topsoil, Earth Grow, and Scott's Premium topsoil to name a few.

Topsoil is not a mineral, but it contains minerals.
