Conservation Agriculture is based on soil conservation techniques and the sustainable use of natural resources to increase productivity levels. This case study describes the introduction and promotion of the 'zero tillage' system in a tropical area of Brazil. The publication has been developed as teaching material for agricultural students and practitioners, and it will also be of interest to all those involved in the promotion of conservation agriculture.

Soil organic matter - the product of on-site biological decomposition - affects the chemical and physical properties of the soil and its overall health. Its composition and breakdown rate affect: the soil structure and porosity; the water infiltration rate and moisture holding capacity of soils; the diversity and biological activity of soil organisms; and plant nutrient availability. This document concentrates on the organic matter dynamics of cropping soils and discusses the circumstances that deplete organic matter and their negative outcomes. It then moves on to more proactive solutions. It reviews a "basket" of practices in order to show how they can increase organic matter content and discusses the land and cropping benefits that then accrue.--Publisher's description.
