The red soils of China are typical in their chemical, physical and mineralogical characteristics of red soils in other tropical and sub-tropical areas of the world, particularly in South America, Africa and south-east Asia. For the most part, these soils are highly weathered and inherently infertile. They are acidic, nutrient deficient, poor in organic matter and have a low water-holding and supplying capacity. They cannot sustain arable cropping systems without the most careful management and are highly susceptible to soil erosion, particularly on sloping land. It is the purpose of this book to present recent research showing how the problems associated with using the red soils in China for sustainable agricultural production can be overcome, using a variety of traditional and novel approaches. In principle, these approaches should be useful in other tropical and sub-tropical countries faced with the problem of making the best use of their fragile red soil resources. The term "in principle" is used deliberately because, of course, the different red soil countries invariably operate within dissimilar socio-economic frameworks. At the present time, China may be considered to be in the process of an "industrial revolution", rather like that that took place in Britain in the late eighteenth and early nineteenth centuries.

China contributes a large part to rice production, one of the most important crops in the world. It is estimated that in China rice constitutes about half of the total food production, covering an area of about 30 % of \08 hectares of cultivated land of the whole country. Owing to the peculiar water regime, paddy soils possess quite different properties physically, chemically and biologically as compared with those of upland soils. Such properties have a conspicuous effect on fertility and management practice of paddy field. For the purpose of summing up the past work and opening up new prospects, a "Symposium on Paddy Soils" was organized under the auspices of Academia Sinica, held on October 19-24, 1980 in Nanjing, which was followed by a seven-day paddy soil excursion in the lower Changjiang Delta. In addition to 120 Chinese soil scientists, 56 guests coming from America, Asia, Europe and Oceania attended the symposium on invitation. A total of 110 papers were presented either orally or by poster. All these are collected and published in the present proceedings which we hope may be helpful to the scientific exchanges between soil scientists of China and other countries.

The humid tropics contain some of the world's richest, most diverse, most important and most threatened environments. This book draws on recent work by geographers, biologists, ecologists, geologists and climatologists to present a complete and integrated appraisal of the natural environment of all the humid tropical regions of the world. The most complete textbook on this key subject. Fully illustrated throughout with photographs and diagrams. Informative case studies and examples. Considers the physical environment as a whole and stresses the link between the elements.

The book contains papers presented at a meeting by eucalyptus experts, scholars, consultants and company managers from different countries and regions. The authors report: (1) the most recent advances in eucalyptus research from different perspectives — genetics, breeding, cultivation techniques, soil nutrition, plantation management, wood utilization, etc.; (2) the world-wide extension and development of the cultivated eucalyptus as a strategic forest tree with great economic, environmental and social significance; (3) plantation management merging ecological, environmental and legal concerns in operations practised by the private sector; (4) new approaches to utilization of eucalyptus woods. This book also represents a successful combination of academic research and practical operation in managing commercial eucalyptus plantations.
