Soil-site relationships in the Roodepoort area, Transvaal
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: M.C. Munnik --- Department of Geography, E. Verster --- Department of Geography, T.H. van Rooyen --- Department of Geography,Fifty hillslope profiles with associated soils were examined in the Roodepoort area, Transvaal, to determine the relationships between soil and site characteristics, as well as the applicability of the toposequence concept. A mesoscale approach was adopted, which implied a relationship... -
Spatial pattern and variability of soils in a granite landscape, north-east of Nelspruit
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: E. Verster --- Department of Geography, Republic of South AfricaMorphological and selected chemical and granulometric properties of eleven soil profiles occurring on five hillslope sites (midslope, upper footslope, mid-footslope, lower footslope and valley bottom) were determined in order to evaluate the spatial pattern and variability of soils in a... -
Genese van 'n tipiese toporeeks in die Suid-Vrystaat
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: D. Haarhoff --- , Republiek van Suid-Afrika P. A.L. le Roux --- Departement van Grondkunde, Republiek van Suid-Afrika M. Hensley --- , Republiek van Suid-AfrikaDie pedogenese van 'n toporeeks in die Rouxville distrik is ondersoek aan die hand van sewe profielgate. Verskeie grond eienskappe is ondersoek. Onder hierdie klimaat is gevind dat moedermateriaal 'n deurslaggewende rol speel by grondvorming. Die moedermateriaal betrokke by hierdie... -
Physicochemical characteristics of communal rangeland soils along two defined toposequences in the Eastern Cape, South Africa
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: MS Lesoli --- Department of Livestock and Pasture Science, South Africa S Dube --- Department of Livestock and Pasture Science, South Africa AO Fatunbi --- Agricultural and Rural Development Research Institute, South Africa B Moyo --- Department of Livestock and Pasture Science, South AfricaTo proffer a sustainable solution to rangeland degradation, an understanding of the innate soil properties is vital. This study investigated the relative association of surface (0–20 cm) soil physicochemical properties, viz. electrical conductivity, cation exchange capacity (CEC), soil organic carbon,... -
Phosphorus sorption kinetics in calcareous soils of selected arid and semi-arid toposequences and its relationship with plant growth
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: A. Jafari --- Department of Soil Science, College of Agriculture, Isfahan University of Technology, Iran H. Shariatmadari --- Department of Soil Science, College of Agriculture, Isfahan University of Technology, Iran Y. Rezainejad --- Department of Soil Science, College of Agriculture, Isfahan University of Technology, Iran Sh. Ghalami --- Department of Soil Science, College of Agriculture, Isfahan University of Technology, IranAn array of kinetic equations has been used to describe time-dependent sorption of P by soils. We investigated P sorption kinetics in calcareous soils at upper-, mid-, and lowerslope positions of two arid and two semi-arid landscapes and its relationship...
