Question

How does loosening soil allow the roots to breathe easily?

Answer 1

When we loosen the soil around plant roots the air present in the atmosphere moves into the free spaces and forms air pockets.

Hence, the plant's roots can easily take in the CO2 it needs to perform its day to day functions...

Hope my answer helps you out.

☞Loosening of soil allows the roots to breathe easily, because it allows them to penetrate into the spaces in between the soil particles which have air trapped in them.
