Soil aggregate stability: The contribution of biological and physical processes
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: M.B. Molope --- Crop production, Agriculture Department, Private Bag X2039,The roles of fungal growth, soil organic matter and particle re-orientation in soil aggregate stabilization during ageing of two British soils with different cropping histories were studied. Soils were subjected to simulated cultivation, and the subsequent changes in aggregate stability... -
Changes in soil aggregate stability during simulated weather cycles
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: M.B. Molope --- Geography Department,The effects of wetting and drying, and freezing and thawing on the stability of aggregates produced by laboratory manipulation or field tillage were studied on two British soils. Changes in aggregate stability were assessed by turbidimetry, with some information from... -
