What is a primary challenge associated with soil erosion in agriculture?

Soil erosion is a significant concern in agriculture, primarily because it negatively impacts agricultural productivity. When soil is eroded, the top layer, which is rich in organic matter and essential nutrients, is removed. This topsoil is vital for plant growth as it provides the necessary nutrients and structure for crops.

As a result of erosion, farmers may face reduced yields and poorer crop quality, which can affect food supply and economy. The loss of topsoil can lead to a decrease in soil fertility over time, making it more difficult for crops to thrive without additional inputs of fertilizers, which can also raise production costs. Therefore, the connection between soil erosion and decreased agricultural productivity is directly tied to the reduction of soil quality and fertility caused by the loss of topsoil.
