Volume 3 takes the subject of better land husbandry further. The book first points out the sort of things which have been, and are being used, but are failing to deliver what is required. It then explains the causes of erosion, the theory and practice of soil and water conservation, and practical and lasting ways to construct terraces, including such details as how to build different kinds of terrace walls. Nothing grows from the top down, as also with soil improvement. It explains in detail the way of achieving practical and sustainable soil and water conservation, practical ways in which farmers can themselves make and use practical and lasting ways to construct terraces, including such details as how to build different kinds of terrace walls.
