The objective of this publication is to offer a reference material for
extensionists, professors, agronomy students, technicians in
general, and for farmers themselves. Through information that is
up-to-date and richly illustrated, 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.
