Question

which is a result of topsoil loss?
increased soil fertility
poor crop production
softened soil surface
deposition of aggregate

Explanation:

Topsoil is rich in nutrients and organic matter, which are essential for plant growth. When topsoil is lost, the soil's ability to support healthy plant growth is diminished. This leads to poor crop production as plants lack the necessary nutrients and a good medium for root development. Increased soil fertility is incorrect as topsoil loss reduces fertility. Softened soil surface is not a direct result of topsoil loss. Deposition of aggregate is also not a typical result of topsoil loss.

Answer:

poor crop production
