This proceedings contains 9 papers providing information on the potential of conservation tillage in a wide-range of geographical, climatological and socioeconomical situations. Results from studies in China, Australia, Iran and Ethiopia are presented. Topics covered include: sustainable tillage methods for irrigated wheat production in different regions of Iran; conservation tillage models for small-scale farming; functional relationships between soil water infiltration and wheeling and rainfall energy; controlled traffic farming in restoring soil structure; short-term effects of tillage and manure on some soil physical properties and maize root growth in a sandy loam soil in western Iran; the impact of 14 years of conventional and no-till cultivation on the physical properties and crop yields of a loam soil at Grafton NSW, Australia; conservation tillage implements and systems for smallholder farmers in semi-arid Ethiopia; controlled traffic farming with no tillage for improved fallow water storage and crop yield on the Chinese Loess Plateau; the effect of alternative tillage and residue cover on yield and water use efficiency in annual double cropping system in North China Plain.
