SOIL PROFILE DEVELOPMENT IN SOME PEACE RIVER SOILS

Acid soil indicators in forest soils of the Cherry River Watershed, West Virginia.

Declining forest health has been observed during the past several decades in several areas of the eastern USA, and some of this decline is attributed to acid deposition. Decreases in soil pH and increases in soil acidity are indicators of potential impacts on tree growth due to acid inputs and Al toxicity. The Cherry River watershed, which lies within the Monongahela National Forest in West Vir...

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...

Soil Phosphorus Forms and Profile Distributions in the Tidal River Network Region in the Yellow River Delta Estuary

Modified Hedley fraction method was used to study the forms and profile distribution in the tidal river network region subjected to rapid deposition and hydrologic disturbance in the Yellow River Delta (YRD) estuary, eastern China. The results showed that the total P (Pt) ranged from 612.1 to 657.8 mg kg(-1). Dilute HCl extractable inorganic P (Pi) was the predominant form in all profiles, both...

Biaxial Reflecting Coals in the Peace River Coalfield

an increasing numbcr af biaxial reflectance indicatrixes arc being reported from coals of >arious ranks from around the world (Cook, et ul., 1972: Stone and Cook. 1979; Hower and Davis. 1981; Levlnc and Davis. 19841. The objective of this preliminary study was to examinc a variety of coals from the Peacc Kiver Coalfield to determine if any biaxial reflecting coals are present, and to dcvise a m...
