Geometrical attributes of pore systems in soil have shown fractal scaling. Scaling in natural materials is inherently statistical, i.e., fractal dimensions may change with scale. While fractal dimensions characterizing pore surface roughness, D s , or scaling of pore sizes, D v , have been reported, seldom are both measurements made at more than one scale. We examine a scale effect...
In arid Australia, various gypsum sediments are widely distributed around salt lakes and along present and ancient drainage lines. They are primarily precipitated from saturated surface and subsurface brines and may be later transported by water or wind. When these primary gypsum sediments are exposed at the land surface and above the ground-water table, they tend to be altered by pedogenic processes,...
Soil grid data were gathered from 110 points and three depths in the Vagia plain, Greece. A total of 48 soil parameters for each point were studied and reduced using multivariate analysis techniques, based on a common variance criterion, and Principal Component Analysis, without loosing less than 8% of the topological information. They were finally reduced to twelve properties which were the most...
Africa, with a total land mass of about 30.7 million km 2 and a population exceeding 746 million persons, has generally lagged behind in agricultural development. Sub-Saharan Africa (excluding South Africa) is the poorest developing region, with 29 out of 34 countries being some of the poorest in the world. The purpose of this study is to develop a Soil Taxonomy map, based on the FAO Soil...
