Tools for Agriculture is a guide to small-scale farming equipment which offers information to smallholder farmers, development workers, and manufacturers all over the world. This revised and updated fourth edition, appearing 25 years after ITDG's original published guide to appropriate equipment, "Tools for Progress", is the first to be produced from a computer database, compiled jointlyw ith GRET to enable systematic and continuous updating. Information has been selected from more than 1200 manufacturers in over 90 countries, and is presented here in ten sections for ease of reference. Each subject area - field power, soil preparation, crop protection - is introduced by a specialist who sets the range of available tools, implements and machines against a background of good farming practice, and the factors to weigh up when making a choice. The theme of effective choice is also considered in the main introduction along with an analysis of why some mechanization projects are more successful than others and how they could be improved. Also included are sources of further information and useful indexes of manufacturers and equipment.
