Soils and Soil Sciences
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...

متن کاملSoil detritivore functioning in heterogeneously contaminated soils
Spatial heterogeneity in abiotic and biotic factors is an important habitat feature of ecosystems as it facilitates potential refuges for less favourable conditions. Heterogeneously contaminated soils can affect specific groups of organisms and their functioning, both directly by toxic effects and by avoidance of contaminated micro-sites. We tested the hypothesis that horizontally heterogeneous...

متن کاملRelationships between soil physicochemical, microbiological properties, and nutrient release in buffer soils compared to field soils.
The retention of nutrients in narrow, vegetated riparian buffer strips (VBS) is uncertain and underlying processes are poorly understood. Evidence suggests that buffer soils are poor at retaining dissolved nutrients, especially phosphorus (P), necessitating management actions if P retention is not to be compromised. We sampled 19 buffer strips and adjacent arable field soils. Differences in nut...
