Modelling pedogenesis in the anthropocene

, 2013
The objective of this paper is to develop a framework for pedogenetic modelling in the Anthropocene, i.e., the present geological epoch during which humanity has become the main factor impacting the environment. We review the concepts of soil evolution as well as 15 existing quantitative models to determine the features of soil evolution modelling in ...

Leaf leachates as a factor in pedogenesis

Journal of the Science of Food and Agriculture, 1955
AbstractThe phenomena of iron reduction and migration, which are characteristic of gley and podsolized soils, are generally regarded as being caused by the action of the humose upper horizons normally present in these soils.In this paper are given the results of an investigation of the properties of water extracts of unhumified plant debris; from the ...
