Download or read book Soil Fertility Decline in the Tropics written by Alfred E. Hartemink and published by CABI. This book was released on 2003 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wide coverage of soils and perennial cropping systems in the tropicsSynthesis of decades of researchChallenges assumptions on the benefits of plantations for soil fertilityIt is generally assumed that soil fertility decline is widespread in the tropics and that this is largely associated with annual cropping and subsistence farming. In contrast, perennial plant cover (as in plantation agriculture) provides better protection for the soil.This book reviews these concepts, focusing on soil chemical changes under different land-use systems in the tropics. These include perennial crops, annual crops and forest plantations. Two case studies, on sisal plantations in Tanzania and sugar cane in Papua New Guinea, are presented for detailed analysis. The author demonstrates that soil fertility decline is also a problem on plantations.

Download or read book Sustainable Agriculture and the Environment in the Humid Tropics written by National Research Council and published by National Academies Press. This book was released on 1993-02-01 with total page 721 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rainforests are rapidly being cleared in the humid tropics to keep pace with food demands, economic needs, and population growth. Without proper management, these forests and other natural resources will be seriously depleted within the next 50 years. Sustainable Agriculture and the Environment in the Humid Tropics provides critically needed direction for developing strategies that both mitigate land degradation, deforestation, and biological resource losses and help the economic status of tropical countries through promotion of sustainable agricultural practices. The book includes: A practical discussion of 12 major land use options for boosting food production and enhancing local economies while protecting the natural resource base. Recommendations for developing technologies needed for sustainable agriculture. A strategy for changing policies that discourage conserving and managing natural resources and biodiversity. Detailed reports on agriculture and deforestation in seven tropical countries.

Book excerpt: Advances in Agronomy continues to be recognized as a leading reference and a first-rate source for the latest research in agronomy. As always, the subjects covered are varied and exemplary of the myraid of subject matter dealt with by this long-running serial. Volume 89 contains six comprehensive and timely reviews. Chapter 1 presents a thorough coverage of wet chemistry and state-of-the art molecular scale techniques, such as x-ray absorption fine structure (XAFS) and nuclear magnetic resonance (NMR) spectroscopies, that can be used to characterize phosphorus in organic wastes. Chapter 2 discusses the Wheat Genetics Resource Center that has served the scientific community for 25 years. These resources have been useful to scientists in 45 countries and 39 of the states in the U.S. Chapter 3 covers various aspects of the biology and management of Stevia, a sweet herb of Paraguay. Chapter 4 is a timely review of aspects of soil fertility decline in the tropics as assessed by soil chemical measurements. Chapter 5 covers nematode interactions and assessment of models for their control on crop plants. Chapter 6 presents data and algorithms on ammonia emission form animal operations, a current area of much interest in the area of environmental quality. Over 40 figures and 32 tables Presents a review of the present and future status of soil science Offers an analysis of biodiversity in agronomy
