This successful book has been extensively revised for the second edition, and is a recent addition to the highly praised Tropical Agriculture Series.
The authors provide a general account of the factors affecting agriculture in the tropics, placing particular emphasis on ways of using recent research findings to improve current farming methods. Bearing in mind the increasing economic restraints imposed on small farmers, they have also emphasised throughout ways of improving the productivity of smallholdings at least cost to the farmer.
The book begins with a description of tropical climates, soils and natural vegetation types, discussing their influence on agriculture. The principles of soil and water conservation, land clearing, drainage and tillage are then outlined. This is followed by discussion of rain-fed arable farming, systems based on swamp rice production, monoculture of perennial crops, and the utilisation of natural and sown pastures. Finally, there are chapters on livestock improvement through better nutrition, hygiene and breeding.
The book is extensively illustrated with line diagrams and photographs and will be a vital source of information for both students of agriculture and practising farm and estate managers.
