    Vertical distribution of living mangrove foraminifera from KwaZulu-Natal, South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    Modern foraminiferal assemblage zones can be used to reconstruct palaeo sea levels when applied to fossil foraminifera down a sediment core. Previous intertidal foraminiferal studies have predominantly focused on assemblages in surface sediments (0–1 cm), with the rationale that surface...
  2. <em>Pinus maximinoi:</em> A Promising Species in South Africa

    Item type: Journal Article • Journal: South African Forestry Journal
    A number of provenance trials of Pinus pseudostrobus initiated by the Oxford Forestry Institute were planted in the Eastern Transvaal Forest Region. Taxonomic studies later revealed that many of the provenances included in these trials were P. maximinoi (previously known...

    The Fieldes and Perrott field test as an aid to identification for podzol B horizons

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The Fieldes and Perrott test for allophane was assessed as an aid to identifying podzol horizons. The test was compared to the chemical criteria for podzol B horizons on 51 B horizon samples collected in the southern Cape. In 37...
  7. An improved phosphorus desorption index for the routine determination of the Ambic 2 phosphorus requirement factor of South African soils

    An improved phosphorus desorption index for the routine determination of the Ambic 2 phosphorus requirement factor of South African soils

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    A short (24 h) laboratory incubation study was conducted and plots of P desorbed in Ambic 2 extraction solutions versus added P were constructed for a wide range of soils of varying P fixing capacity representative of the province of...
