Physical properties of some highveld Vertisols
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: K. Snyman --- , M.V. Fey --- Department of Soil Science and Agrometeorology, A. Cass --- Department of Soil Science and Agrometeorology,Surface (0–20 cm) soils were sampled at 100 m intervals along a 3 km transect through Vertisols derived from dolerite and Ecca group mudstone near Standerton, Transvaal. The two geologically correlated soil bodies, which historically appear to have formed the... -
Physical and clay mineralogical properties of some Natal and eastern Transvaal soils
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: A. Cass --- , Australia M.A. Johnston --- Department of Agriculture and Water Supply,Soils, collected from the south-eastern Transvaal, Natal north coast and the more arid areas of the Natal interior, were examined using physical, chemical and mineralogical methods. Most of the soils were associated with particular management problems such as poor internal... -
Quantitative criteria for distinguishing melanic from vertic soil horizons in the central Kruger National Park
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: S.W. Fraser --- Department of Geography, T.H. van Rooyen --- Department of Geography, E. Verster --- Department of Geography,Criteria based on shrink-swell potential, viz. linear shrinkage and COLErod, were used to distinguish between melanic and vertic soil horizons of the Mooiplaas region in central Kruger National Park. For linear shrinkage the proposed boundary value separating melanic and vertic... -
Physical properties of Tectona grandis (Lamiaceae) juvenile wood thermally modified in a closed system
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: Natália A Cunha --- , Brazil Tiago A Gales --- , Brazil Amanda M Nunes --- , Brazil Glaucileide Ferreira --- , Brazil Thaís M Brito --- , Brazil Adriano Ribeiro de Mendonça --- , Brazil Djeison C Batista --- , BrazilThis paper reports the first results of the effect of an industrial closed-system thermal modification process on the physical properties of fast-growth teak wood (Tectona grandis L.f.). The wood (juvenile) came from thinning a 15–18-year-old plantation located in Mato Grosso...
