Yes you read the title correctly, elimination, not alternative, not creative, elimination. Can irrigation truly be eliminated? In my view absolutely, at least in many instances and one of our all time most popular guests Paul Wheaton returns to TSP to discuss exactly how to do it.
Join us today as we discuss swales, key line systems, terraces, hugelkultur, and over a dozen other ways plants get water in natural systems.
Irrigation is one of the most costly components of modern agriculture, it is also depleting one of most precious life giving resources, water. Yet think about it, there are millions of acres of prairie, forest, jungle and savana that produce massive yields of plant matter every year and who irrigates them? Imagine the impact if these systems could be scaled up to eliminate even 15% of current agricultural irrigation requirements.
The good news is many of them can be done in your own back yard, some are simple and others are complex but just by making a pile of rocks, burying some rotting wood or moving around a bit of soil you can vastly reduce your personal irrigation requirements.
