Studies in South Australia in the 1930-40's showed that the coastal areas .and, to a lesser extent, the areas inland had inadequate levels of cobalt and copper for livestock health and production. Since these studies, selenium responsive conditions have been recognised in livestock depastured on the ironstone soils in the higher rainfall areas and also in isolated, but at present ill-defined, a...

A new species of spiral ginger (Costus: Costaceae) from Gabon, Africa is described. Costus loangensis H. Maas & Maas is found in the coastal region on white sand soils under a tropical rain forest canopy. It is morphologically distinct from all other African species of Costus but shows some similarities in floral form with the savanna-inhabiting Costus spectabilis (Fenzl) K. Schum. and similari...

Recent studies suggest that nitrogen can have significant effects on microbial activity and carbon storage by causing shifts in fungal:bacterial activity such that bacterial degradation pathways become dominant under high nitrogen conditions. If true, changes in fungal:bacterial (F:B) ratios could have a major impact on carbon storage in urban pollution affected soils that receive high amounts ...

In this work, PIXE experiments were performed for measuring heavy and light elements' (ranging from aluminium to lead) concentrations inside various polluted and unpolluted soils as well as liquid samples collected from different phosphate factory sewers in the El Jadida-Safi Atlantic coastal region (Morocco). In addition, uranium ((238)U) and thorium ((232)Th) contents were evaluated in the sa...

Corn (Zea mays L.) grown on sandy Atlantic Coastal Plain soils is often unresponsive to applications of K fertilizer. As part of a field study on the response of irrigated, intensively managed corn to K applications, we characterized four representative Hapludults from the Delaware Coastal Plain and evaluated their K status. The soils were generally quite sandy with maximum clay contents of 11....

A large number and growing proportion of both single lot residential and larger scale new developments in the Hunter Region are not serviced by a conventional reticulated sewerage system. In such cases, wastewater treatment, its possible reuse and final disposal, is on-site, where the effluent is generated. A range of geotechnical factors including the site geology, geomorphology, soils, availa...

Impacts of contrasting land-use history on composition, soils, and development of mixed-oak, coastal plain forests on Shelter Island, New York. J. Torrey Bot.

In this short communication we describe the temporal variation of PAHs fingerprints and burden in surface soils from coastal and central valley sites in South Central Chile, with different anthropogenic influence. PAHs were extracted with accelerated solvent extraction and measured by HPLC with fluorescence detection. Levels of ∑ 15 PAHs were relatively low in both sites ranging between 190 to ...

Integrated studies on the interplay between soils, periglacial geomorphology and plant communities are crucial for the understanding of climate change effects on terrestrial ecosystems of maritime Antarctica, one of the most sensitive areas to global warming. Knowledge on physical environmental factors that influence plant communities can greatly benefit studies on the monitoring of climate cha...

The accumulation of excess soil phosphorus (P) in watersheds under intensive animal production has been linked to increases in dissolved P concentrations in rivers and streams draining these watersheds. Reductions in water dissolved P concentrations through very strong P sorption reactions may be obtainable after land application of alum-based drinking water treatment residuals (WTRs). Our obje...
