Answer 2

Answer:

a) Poor soil is either too heavy (clay soil which holds nutrients and water but doesn't drain well, and can be hard for the plant roots to push through), or too light (sandy soil which drains very well, but means water and nutrients can just wash away). that is why soil is not a mineral.
