In crop rotation, deep-rooted crops should follow shallow-rooted crops because deep-rooted crops

The correct answer is that deep-rooted crops should follow shallow-rooted crops in crop rotation because they feed from different soil layers. Shallow-rooted crops mostly utilize nutrients from the topsoil, while deep-rooted crops obtain nutrients from deeper soil layers. By alternating these crops in a particular field, nutrients will not be depleted from a particular soil layer, and the soil will remain healthy and productive. Additionally, the use of deep-rooted crops such as legumes can help to improve soil structure, aerate the soil, and increase water infiltration rates, which will further enhance soil health and crop productivity.
