Compacted soil will absorb too much water. Plants cannot grow when soil is compacted. Minerals are destroyed when soil is compacted. Compacted soil increases soil acidity.
I gave my students this multiple choice question: The weight of heavy machinery compacts soil, especially when it is wet. Why do farmers avoid driving their machinery across wet ground?

Only one answer is correct among these 4 choices:
- Compacted soil will absorb too much water.
- Plants cannot grow when soil is compacted.
- Minerals are destroyed when soil is compacted.
- Compacted soil increases soil acidity.

Could you tell me which one is correct?

Plants cannot grow when soil is compacted.
