Postpyrogenic soil dynamics is an informative tool for studying elementary processes in extreme temperature conditions and predicting short time environmental changes of catastrophic landscape changes. Soil organic matter (SOM) system evolution the most rapid process postpyrogenic development. In this relation, focus on humus structure important understanding these dynamics. restoration after s...

Temporal changes in soil development were assessed on fluvial terraces of the Little River upper Coastal Plain North Carolina. We examined five profiles from each six surfaces spanning about 100,000 years. Soil-age relationships evaluated with inter-surface clay mineral comparisons and regression chemical properties versus previously reported optically-stimulated luminescence ages using most de...

The environmental quality of soil in the central part of the Northern Plateau of Spain has been analyzed by studying the heavy metal content of 166 samples belonging to the horizons A, B and C of 89 soil profiles. The analysis to assess the environmental risk of heavy metals in the soil was carried out by means of the spatial distribution of nine heavy metals and the use of several pollution in...

a r t i c l e i n f o Lamellae are thin, often discontinuous layers of clay-enriched material that are associated with iron oxides and may occur in Alfisols, Ultisols, Mollisols, Entisols, Inceptisols, or Spodosols. Our analysis of the SSURGO database revealed that there are 118 soil series with lamellae that represent six orders, 14 suborders, and 25 great groups, and 25 subgroups. In Soil Tax...

Land evaluation is imperative for its efficient use in agriculture. Therefore, this study aimed at assessing the suitability of a region West El-Minia cultivating some major crops using geographical information system (GIS). The results focus on allocating space sugar beet and utilizing free period other crops. This exploitation helps to maintain quality land increase fertility by crop rotation...
