Soil genesis, soil classification and soil survey

Geoderma, 1970
Abstract Mutual relationships exist between soil genesis, soil classification and soil survey. The first two subjects are dealt with separately. Some of the general lines in soil genetic investigation are traced. Next trends in soil classification are dealt with.

Feedback processes in soil genesis

Geoderma, 1978
Abstract Feedback can be defined as the returning of a part of the effects of a given process to its beginning or to a preceding stage so as to reinforce or modify that process. Feedback processes are self-accelerating because of continuous reinforcement of the causes starting them. Up to a certain moment, reinforcement is proportional to the effects

Surface-water gley soils in Bangladesh: Genesis

Geoderma, 1977
Abstract Extensive areas of periodically wet, acid soils in Bangladesh have a seasonally fluctuating pH of the surface horizon and evidence for net clay loss. Morphological, chemical, mineralogical and other data mainly on a typical profile of these surface-water gley soils indicate a clay loss of some 1.5 kg/dm' ; alteration of smectite to a soil ...

Soil landscape systems: A model of soil Genesis

Geoderma, 1975
Abstract The paper describes a model of the soil system. There are two different, partly complementary means of building such a model. One approach is to construct, using empirical physical science methods, an isomorphic model, in which each and every component (variable) of the system is an element in the model. The other approach is to build, using
