  1. Vermicompost leachate improves seedling emergence and vigour of aged seeds of commercially grown <em>Eucalyptus</em> species

    Vermicompost leachate improves seedling emergence and vigour of aged seeds of commercially grown <em>Eucalyptus</em> species

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Vermicompost leachate (VCL) is a liquid generated by earthworms and microorganisms during the conversion of organic matter into vermicompost. Vermicompost leachate is rich in nutrients and believed to contain both known and unknown plant growth substances, which are beneficial to...
  2. 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...
  3. Influence of Soil Organic Matter Content on the Responsiveness of <em>Eucalyptus grandis</em> to Nitrogen Fertiliser

    Item type: Journal Article • Journal: South African Forestry Journal
    It is widely recognised that the inherent nitrogen (N) mineralisation capacity of a soil is directly related to the organic matter content. Consequently, in estimating the N requirements of Eucalyptus grandis at planting this mineralisation potential must be taken into...
  4. The Influence of Site Factors on the Foliar Nutrient Content of <em>Eucalyptus grandis</em> in Natal

    Item type: Journal Article • Journal: South African Forestry Journal
    Although foliar analysis is commonly used to diagnose the nutritional status of trees and their ability to respond to fertilising, it is also a measure of site type and quality. The availability of nutrients in the soil varies with climatic...
  5. Regeneration Procedures of <em>Pinus radiata</em> in the Southern Cape Province

    Item type: Journal Article • Journal: South African Forestry Journal
    The present paper is part 3 in the series of publications dealing with the regeneration of Pinus radiata in the Southern Cape Province. The objective of the study was to compare the organic carbon contents in the soils and the...
  6. Herbage intake by cattle on <em>tarchonanthus</em> veld in the Northern Cape as affected by stocking rate and grazing system<sup>1</sup>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    In a trial with young Bonsmara cattle, four different stocking rates (10, 7, 6 and 4 ha/large stock unit) were applied in both a rotational and continuous grazing system. Feed intake was estimated during spring, summer, autumn and winter for...
  7. Voluntary intake of several planted pastures by sheep and an assessment of NDF and IVDOM as possible predictors of intake

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The aim was to study the quality and quantity of pasture selected by sheep on various planted pastures. A further aim was to assess NDF and IVDOM as easy measurable parameters for use in equations to predict intake. Pasture samples...
  8. Considerations on the sustainability and environmental impact of intensive pastures

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Intensive pastures form an important component of livestock production systems in South Africa. The sustainability and environmental impact of intensive pastures via their effects on soil properties and nutrient fluxes vary considerably depending on the systems adopted. Soil organic C...
  9. Die rol van sekere omgewingsfaktore by alachloraktiwiteit

    Die rol van sekere omgewingsfaktore by alachloraktiwiteit

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Biotoetse met graansorghum (Sorghum bicolor L.) is in potte in glashuise en groeikabinette uitgevoer. Geselekteerde grond- eienskappe is gekorreleer met alachloraktiwiteit. Organiese materiaalinhoud (% C) was die beste gekorreleerd met die aktiwiteit van alachlor en pH die swakste. Die r-waardes...
  10. Improving the fermentation ability of unripe air-cured tobacco

    Improving the fermentation ability of unripe air-cured tobacco

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The fermentation of dark air-cured tobacco depends on its fermentation ability. Dry spells during the growth period can contribute towards unripe tobacco with poor fermentation ability. By blending such tobacco at a 1:1 ratio with tobacco of good fermentation ability,...
