So, from what I’m reading, if I oversimplify to an extreme, swales are dug into the contour lines of a property with the berm on the downslope side of the swale. So, for instance, if I wanted to plant food on my property, using a modified Ruth Stout method, I would do best to swale and berm on the contour lines instead of in straight rows?
Here’s a picture of one section of my property from the GIS mapping website.
