  1. Mineralisation of organic fertilisers used by urban farmers in Harare and their effects on maize (<em>Zea mays</em> L.) biomass production and uptake of nutrients and heavy metals

    Mineralisation of organic fertilisers used by urban farmers in Harare and their effects on maize (<em>Zea mays</em> L.) biomass production and uptake of nutrients and heavy metals

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Nutrient release patterns and heavy metal contamination risks associated with animal manure and organic municipal wastes used as basal fertilisers are largely unknown in Zimbabwe. Carbon, nitrogen and phosphorus mineralisation patterns were determined in a 56-day incubation experiment of domestic...
  2. Soil organic carbon and nitrogen stocks along a seasonal wetland (dambo) transect in central Zimbabwe

    Soil organic carbon and nitrogen stocks along a seasonal wetland (dambo) transect in central Zimbabwe

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Ecosystems of central and southern Africa are occupied by some of the largest seasonal wetlands commonly called dambos. Dambos are likely to store huge stocks of soil organic carbon (SOC) because of their saturated conditions. However, most available literature report...
  3. Yield, nutrient and heavy metal uptake of leafy vegetables grown in sewage sludge and poultry manure amended soils

    Yield, nutrient and heavy metal uptake of leafy vegetables grown in sewage sludge and poultry manure amended soils

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Urban farmers in Harare grow vegetables in soils fertilised with poultry manure (PM) and sewage sludge (SS). Feed and storage management influence nutrient supply of these organic amendments. Nitrogen mineralisation of PM and SS were determined in a non-leaching and...
  4. Effectiveness of cattle manure and nitrogen fertilizer application on the agronomic and economic performance of maize

    Effectiveness of cattle manure and nitrogen fertilizer application on the agronomic and economic performance of maize

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The effects of N fertilizer and aerobically composted cattle manure, applied separately or in combination, on maize (Zea mays L.) grain yields and net benefits were determined over three seasons. A field experiment was established on a moderately leached sandy...
  5. The effect of hydroxide solutions on the structural stability and saturated hydraulic conductivity of four tropical soils

    The effect of hydroxide solutions on the structural stability and saturated hydraulic conductivity of four tropical soils

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Industrial and domestic effluents are widely applied to soil as a way of dumping, and/or source of nutrients and water for plant growth. The potential effects of sodium hydroxide (NaOH) and potassium hydroxide (KOH), which are common hydroxides found in...
  6. Effect of soil fertility management strategies and resource-endowment on spatial soil fertility gradients, plant nutrient uptake and maize growth at two smallholder areas, north-western Zimbabwe

    Effect of soil fertility management strategies and resource-endowment on spatial soil fertility gradients, plant nutrient uptake and maize growth at two smallholder areas, north-western Zimbabwe

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    We investigate the effects of smallholder farmer resource—endowment and soil nutrient management strategies on plant nutrient uptake and growth across soil fertility gradients under semi-arid conditions. Soil fertility gradients as influenced by farmers’ resource availability may affect the response of...
  7. Is this really what women want? An analysis of <em>Fifty Shades of Grey</em> and modern feminist thought

    Is this really what women want? An analysis of <em>Fifty Shades of Grey</em> and modern feminist thought

    Item type: Journal Article • Journal: South African Journal of Philosophy
    The article briefly presents a paradox generated by the unprecedented sales of the Fifty Shades of Grey trilogy by E.L. James and explores some pros and cons of this new literary genre (‘erotic fiction’), while examining the discourse of polarised...
  8. Practicing pan-Africanism: an anthropological perspective on exile-host relations at Kongwa, Tanzania

    Practicing pan-Africanism: an anthropological perspective on exile-host relations at Kongwa, Tanzania

    Item type: Journal Article • Journal: Anthropology Southern Africa
    This paper explores exile-host relations at Kongwa, where southern Africa's first guerrilla soldiers lived alongside villagers in rural, central Tanzania between 1964 and 1978. Drawing from the author's previous research on SWAPO's exile camps, recent publications about the ANC in...
  9. New knowledge and the university

    New knowledge and the university

    Item type: Journal Article • Journal: Anthropology Southern Africa
    What forms of knowledge have legitimacy in the contemporary university? By using Actor-Network Theory to unravel the strands in a recent dispute about access to skeletons from a burial ground in Cape Town, this paper shows how circulating systems of...
