Ponds, Swales And Keyline Systems: Water For Your Dried Up Farm Whether you have some water to play with or your land is bone dry, we're going to talk about how any dried patch of dirt can be converted into a lush jungle of crops and forage.

Neither of these are irrigation sytems.
Both of these are techniques to hold water (from rain) and soil on a slope.
There is a whole book on keyline stuff, but one of the most popular techniques is to use a keyline plow (not a regular plow) which sorts digs a tiny channel about 18 inches underground. And you want this channel to run slightly downhill AWAY from ravines.
A swale is like a ditch that is perfectly level. So rain water builds up in it and passes through it. The swale holds soil and concentrates moisture.
