        Ecophysiology of Tropical Crops covers the knowledge and opinion on ecophysiology of the major tropical crop plants. The book discusses the fundamental ideas about the numerical description of plant development and considers effects of climatic factors (e.g., temperature, light, and water) on physiological processes in Edition: 1.

      The relationships between soils, microbes and humans are of crucial relevance in the tropics, where plant stress and microbial activity are exacerbated. This volume of Soil Biology presents the living component of tropical soils, showing how it is shaped by environmental conditions and emphasizing. Soil survey horizons v no.2 pp. 39 ISSN: Subject: tropical soils, soil classification, soil surveys, Ghana Abstract: Early soil surveyors in the tropics encountered unique environmental conditions. Soil survey was challenging in dense tropical vegetation because it was difficult to observe the landscape without clearing survey Cited by: 1.

      The conditions for soil development in the lowland tropics are described, in particular the soil-forming factors, climate, parent material, topography and organisms, and their interactions through time. Of particular importance is the climate of the lowland tropics, which has a major influence on the nature of soil development because of high temperatures and the duration of the periods when. Two things seem clear: one that the principles of good soil management in the tropics have yet to be fully understood, the other that tropical soils are liable under improper management to.

Chandrasekaran, Dr. Annadurai and Dr. Somasundaram. An analysis of ISRIC (mainly tropical) and USDA (mainly temperate) soil databases showed that soils in the tropics have higher clay content, lower cation exchange capacity, higher bulk density, lower water content at − 10 kPa and − kPa than soils in the temperate by: In the tropics, soil fertility is generally low (Hartemink, ; Zingore et al., ) and in tropical Africa, soil fertility issues have become of mounting interest due to the growing need to.

The tropics. This book focuses on shifting cultivation and the associated processes of secondary succession and soil fertility restoration in the tropics. Thus, it is important to define the tropics and outline their main features, as the agricultural system of shifting cultivation is focused on this region.

The book by Juo and Franzluebbers is the best book ever written on the subject of tropical soils and their management for sustainable agriculture. Authors discused systematically the properties of the major tropical soils, their linkage with agroecosystems and management 5/5(1).

The properties and potential of soils of the tropics are poorly understood. The old idea that laterite is formed when tropical soils are cleared is true of only a small proportion of the area.
