      Maintaining an appropriate level of soil organic matter and biological cycling of nutrients is crucial to the success of any soil management in the humid tropics. Cover crops, mulches, compost, or manure additions have been used successfully, supplying nutrients to crops, supporting rapid nutrient cycling through microbial biomass, and helping.   Maintaining an appropriate level of SOM and biological cycling of nutrients is crucial to the success of any soil management in the humid tropics (Fernandes et al. ). If a soil is continuously cultivated, a loss of SOM is the consequence, being approximately 50% of total organic carbon (TOC) after 65 years on a Chernozem under a temperate.

      Sustainable land management for maintenance of soil organic carbon and total soil nitrogen dynamics should be locally and globally developed and adopted for a more sustainable agricultural system.

Sustainable Management of Soil Resources in the Humid Tropics book. Read reviews from world’s largest community for readers.5/5(1). Basic concepts of sustainable land use in the humid tropics. Requirements of a sustainable improved agricultural system.

High energy flux 2. Less drudgery and more dignity 3. Effective water management 4. Soil restorative 5. Ecologically compatible.

Components of a sustainable system. Nutrient management 2. Erosion management 3. Research information on methods of deforestation for conversion to agricultural land use and on soil and crop management systems for the sustained use of soil and water resources in the humid tropics is presented.

Examples of appropriate techniques and their impact on production, soil quality and the environment are given and the characteristics of improved farming system, Cited by: The humid tropics ecosystem covers about billion ha of land area and has a total human population of about 2 billion distributed over 60 countries, and contains about 1 billion ha of the remaining tropical rain forest of the world.

However, its predominant soils, Oxisols and Ultisols, comprising 63% of the total land area, have low by: ISBN: OCLC Number: Notes: "UNUP"--Title page verso.

Description: xvii, pages: illustrations, map ; 21 cm: Responsibility. "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. But soil erosion (one component of land degradation) jeopardizes the sustainable delivery of these services worldwide, and particularly in the humid tropics where erosion potential is high due to heavy rainfall.

The Millennium Ecosystem Assessment pointed out the role of poor land-use and management choices in increasing land degradation. The development of sustainable production systems suitable for areas with low-quality soil and water resources rests on an appreciation of the constraints on agricultural productivity in the humid tropics (National Research Council, ; Savage, ).

(Sanchez. ) Improved germplasm plays an important role in the development of sustainable land-use systems. It is important to select new crops and develop improved varieties that can tolerate acid soil conditions and high concentrations of Al and Mn in the sub-soil, and grow under continuously warm and humid environments with high pressure from diseases and pests.

There is also a growing concern on soil degradation and environmental pollution with high inputs agriculture but these can be avoided with good soil management.

The first approach in soil management is to identify the soil constraints to crop production and assess their degree of severity.

In the humid tropics, these detriments are closely. 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. Unsustainable farming practices such as shifting cultivation and slash-and-burn agriculture in the humid tropics threaten the preservation of the rainforest and the health of the local and global environment.

In weathered soils prone to cohesion in humid tropic due to low Fe and carbon content and the enormous amounts of P that can be adsorbed, sustainable soil use is heavily. The first four parts of the book cover the physical basis of hydrology in the humid tropics: climatology, meteorology, process hydrology, sedimentation, water quality and freshwater ecology.

This is followed by extensive treatment of the human and societal issues: land-use changes, water resource management, and rural and urban water supply in. The present book examines the contribution that forest soil science and forest ecology can make to sustainable land use in the humid tropics.

Four main issues are addressed: characteristics and classification of forest soils, chemical and hydrological changes after forest utilization, soil fertility management in forest plantations and.

In the humid tropics, the minerals in the parent rock generally undergo strong chemical tendency is to hydrolyze and leach away the silica and to accumulate iron and aluminum oxides. This book summarizes current knowledge of the properties and dynamics of soil organic matter in the tropics, its role in determining soil quality, its stability and turnover, and the options for management in the context of tropical landuse systems, for a readership of resource scientists, economists and advanced students.
