A fundamental problem that agro-environmental sciences have to face today is the lack of interdisciplinary linkages between the various disciplines dealing with agriculture and environment and the physics of the “soil medium” organization, which is the object of study of the pedology. Currently, the soil medium is far from being considered as the organized physical medium providing the physical...

Weathering is a complex process comprising physical disaggregation, chemical and biological decomposition of rocks and minerals transforming complex structure minerals in simpler ones. Hydrolysis of silicates is perhaps the most important process but associated certainly to biological weathering. It is discussed the role ofwaters: activities/concentrations of chemical species, pH, Eh, importanc...

Soil science is a relatively new discipline which has mainly developed since the 1880s. It uses terms, methods and processes borrowed from other basic disciplines like climatology, geology, chemistry, physics and biology, but with a direct application to soils. At present, it is difficult to speak about one single science but as soil sciences, as they cover several fields including: pedology (o...
