Green Manurecover Crops And Crop Rotation In Conservation Agriculture On Small Farms

"The objective of this publication is to offer a reference material for extensionists, professors, agronomy students, technicians in general, and for farmers themselves ... it strives to facilitate the adoption and diffusion of no-tillage, the use of green manures, and the practice of crop rotation on small farms. The publication describes the principal species of green manures and, at the same time, informs in detail how to insert green manures into small farm production systems according to soil fertility and major crops. It also deals with the residual effect of green manures on main crops and analyzes the economic implications of these practices."--P. [4] of cover.
