About this episode

This episode discusses how frequent irrigation can lead to higher air content in the soil despite lower average water content.

It sounds counterintuitive at first, that you can maintain a lower average water content in the soil, and a higher air content in the soil, by applying irrigation every day. Once upon a time, I thought the way to keep soils drier and with more air was to implement deep and infrequent irrigation.
