4 How can non-stop intensive arable farming affect soils?

Topsoil structure may weaken with reduced organic material Cereal crops build up soil nutrients Intensive faming has no effect on soil The soils can become more waterlogged

By encouraging burrowing animals to burrow Deforestation doesn't ever increase soil erosion By increasing surface water runoff By increasing drainage down

6 Where does soil eroded by water go to?
