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.

Available in PDF, EPUB and Kindle. Book excerpt: The population of the world is expected reach 6 bilion by the year 2000 (up from 4.7 bilion in 1983). This rapid expasion has created the need for much more food that has to be produced by opening up new lands for farming. The crops (which are the basis of nearly all of man's food) take their food, the chemical elements that are essential nitrients, from the soil in which they are rooted. In centuries past the soils supplied enough nutrients to maintain traditional agricultura systems.

Available in PDF, EPUB and Kindle. Book excerpt: It is possible to study the fate of potassium fertilizer in highly weathered acid soils of the tropics because low amounts of potassium-fixing and potassium-releasing minerals are present. Potassium that is not leached or removed from the field in harvested material remains available on the soil exchange complex. On a Dark Red Latosol in Central Brazil, leaching began to occur only with the addition of 300 kg/ha K as KCl, which is well above the recommemded rate. The potassium content measured in grain crops varied with K status of the soil, from 1,4 percent to 1.9 percent in soybean and 0.23 percent to 0.39 percent in maize. The amount of K that will be exported from the field as grain is easily calculated, and at least this amount of K must be returned to the soil yearly in order to maintain production. If the stover is also removed, its K content should be taken into account as well. Forages removed from the field may contain 1 percent to 3 percent K on a dry-mattrer basis(...).
