Heavy rains/flooding, or crops/plants that destroy the nutrients in the soil (like the cotton plant).
You probably are thinking about soil erosion. When the topsoil and minerals wash away, it is harder for plants to grow.
Dig under the grass and topsoil will be under the grass. Topsoil is that is mainly sold in bags for your gardening.

Soil value can be reduced by erosion, which removes topsoil and degrades soil quality, as well as contamination from pollutants, chemicals, or heavy metals which can render the soil unsuitable for cultivation.
There are several ways that nutrient minerals are lost from the soil. The overuse of the soil in farming, natural weather inclinations and over population are just some of the ways.

Erosion causes the loss of topsoil. Topsoil from thousand of acres of farmland lost to water and wind erosion each yaer in the united states alone.
Deforestation can affect topsoil in two significant ways. First leaves and branches that fall from trees as well as fallen trees themselves decompose. This decomposed matter is a major component of topsoil. If an area is deforested then much less new topsoil will be formed. Secondly, when an area is deforested wind and rain can cause the unprotected topsoil to be blown or washed away.
Topsoil can be lost through erosion caused by wind, water, or human activities like deforestation and agriculture. Additionally, compaction from heavy machinery and overgrazing can reduce topsoil quality and lead to its loss.
It depends on factors such as climate, vegetation, and type of soil. In some cases, it may take ten years or longer for nature to rebuild lost topsoil, while in other cases it could happen more quickly if conditions are favorable for soil regeneration. Regular soil conservation practices can help speed up the process of rebuilding topsoil.
Topsoil can be lost through erosion caused by water, wind, or human activities like deforestation or intensive agriculture practices. When topsoil is removed faster than it can be replenished, it can lead to a decrease in soil fertility and productivity, affecting plant growth and ecosystem health.
If topsoil continues to be lost, it can lead to decreased soil fertility, reduced crop yields, and increased vulnerability to erosion. It can also disrupt ecosystems, impacting biodiversity and overall ecosystem health. Implementing soil conservation practices can help prevent further loss of topsoil.
