Regional sustainability in table grape production on saline soils
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: W. P. de Clercq --- Department of Soil Science, South Africa M. Van Meirvenne --- Department of Soil Management and Soil Care, BelgiumA study was done in South Africa to investigate the state of the soil salt content and its effect on plant growth on a regional rather than a point basis. The study site went through a development phase since 1996... -
Improved usefulness of continental soil databases for agricultural management through local adaptation
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Mats Söderström --- International Center for Tropical Agriculture (CIAT), Kenya Kristin Piikki --- International Center for Tropical Agriculture (CIAT), Kenya Jeremy Cordingley --- Crop Nutrition Laboratory Services Ltd, KenyaThe usefulness of a continental digital soil map (AfSoilGrids250) was investigated at two levels relevant for agricultural fertiliser recommendations in Rwanda (point locations and administrative sector unit averages). Analysis of 900 soil samples for pH and soil organic carbon (SOC)... -
Comparative methods for predicting cyanide pollution in artisanal small-scale gold mining catchment by using logistic regression and kriging with GIS
Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: L. C. Razanamahandry --- International Institute for Water and Environmental Engineering (2iE), Department of Water and Sanitary Engineering, Laboratory of Water, Burkina Faso P. M.

Manikandan --- UNESCO-UNISA Africa Chair in Nanoscience’s/Nanotechnology Laboratories (U2AC2N), College of Graduate Studies, South Africa M. Maaza --- UNESCO-UNISA Africa Chair in Nanoscience’s/Nanotechnology Laboratories (U2AC2N), College of Graduate Studies, South Africa H. Yacouba --- International Institute for Water and Environmental Engineering (2iE), Department of Water and Sanitary Engineering, Laboratory of Water, Burkina FasoIt has been reported that persistent cyanide pollution occurs in artisanal small-scale gold mining (ASGM) catchment areas in Burkina Faso. In the present study, logistic regression (LR) and Regression Kriging (RK) methods were applied to predict cyanide pollution hazard at... -
Spatial variability of herbage yield, grazing capacity and plant diversity in a tropical savannah rangeland ecosystem
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: ND Anane --- University of Ghana, Ghana R Ayizanga --- University of Ghana, Ghana FO Sarkwa --- University of Ghana, Ghana T Ansah --- University for Development Studies, Ghana EC Timpong-Jones --- University of Ghana, GhanaTo improve ruminant livestock production, evaluation of rangelands must be a routine. Rangeland evaluation gives information about the vegetation structure, biomass yield and quality. The Guinea savannah rangelands of Ghana lack research that characterises the spatial variability of herbage yield...
