    Item type: Journal Article • Journal: South African Forestry Journal
    The present paper, which discusses the regeneration of Pinus radiata, represents Part 1 of a series of publications based on experimental studies of the subject. It provides information about the background of the trials and discusses the modification of soil...
  2. Quantitative criteria for distinguishing melanic from vertic soil horizons in the central Kruger National Park

    Quantitative criteria for distinguishing melanic from vertic soil horizons in the central Kruger National Park

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Criteria based on shrink-swell potential, viz. linear shrinkage and COLErod, were used to distinguish between melanic and vertic soil horizons of the Mooiplaas region in central Kruger National Park. For linear shrinkage the proposed boundary value separating melanic and vertic...
  3. Invloed van bewerking en besproeiing op die verwering van gneis in die Augrabies-gebied

    Invloed van bewerking en besproeiing op die verwering van gneis in die Augrabies-gebied

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Fisiese, chemiese en mineralogiese kriteria is gebruik om te bepaal of veranderinge in eienskappe van gronde op gneise, in die Augrabies-gebied, as gevolg van bewerking en besproeiing plaasgevind het. Bewerking en besproeiing van die halfverweerde gneise het die verweringsproses versnel...
  4. Die invloed van grondbewerking op enkele grondeienskappe en die gevolglike ontwikkeling en opbrengs van koring in Suid-Kaapland

    Die invloed van grondbewerking op enkele grondeienskappe en die gevolglike ontwikkeling en opbrengs van koring in Suid-Kaapland

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Vier verskillende bewerkingsbehandelings, wat Wissel in bewerkingsintensiteit van die intensiewe, konvensionele. skaar- en skottelbewerkingstelsel tot geen-bewerking, is oor 'n periode van 6 jaar vergelyk ten opsigte van die uitwerking op grondfaktore en die groei en opbrengs van koring. In hierdie...
  5. Importance of selected soil properties on the bioactivity of alachlor and metolachlor

    Importance of selected soil properties on the bioactivity of alachlor and metolachlor

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Bioassays with grain sorghum (Sorghum bicolor L. Moench) cultivar NK222 were conducted in a glasshouse. Thirty-four natural soils were used in each of two experiments with alachlor [2-chloro-2′,6′-diethyl-N- (methoxymethyl) acetanilide] and metolachlor [2-chloro-6′-ethyl-N-(2-methoxy-1-methylethyl)acet-otoluidide] respectively. Linear regression analyses were performed to...
  6. Importance of selected soil properties on the bioactivity of acetochlor and metazachlor

    Importance of selected soil properties on the bioactivity of acetochlor and metazachlor

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The bioactivity of acetochlor (2-chloro-N-(ethoxymethyl)-6′-ethyl-o-acetotoluidide) and metazachlor (2- chloro-N-(1-pyrazolylmethyl)-aceto-2′,6′-xylidide) was evaluated in thirty-two soils under controlled conditions. Grain sorghum (Sorghum bicolor L. Moench) cultivar NK222 was used as the indicator plant in the bioassays. Bioactivity was correlated with organic matter...
  7. Soil properties as influenced by cultivation of the aromatic shrub <em>Artemisia afra</em>

    Soil properties as influenced by cultivation of the aromatic shrub <em>Artemisia afra</em>

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The herbaceous aromatic shrub African wormwood (Artemisia afra) is thought to be indigenous to the Eastern Cape region of South Africa. In the natural environment, wherever the plant grows, patches of hard, bare ground develop around the plant. To investigate...
  8. Use of solid waste bagasse from a paper mill as an organic amendment and its effect on some soil properties: a case study

    Use of solid waste bagasse from a paper mill as an organic amendment and its effect on some soil properties: a case study

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    At a paper mill in KwaZulu-Natal, South Africa bagasse waste was disposed of by burying it in a layer resulting in variable sugar cane growth. The waste was mostly organic fibres, had a high water holding capacity, and contained small...
  9. Relationships between Ambic 1 and Bray 1 extractable phosphorus in some South African arable soils

    Relationships between Ambic 1 and Bray 1 extractable phosphorus in some South African arable soils

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    South African analytical laboratories use different extractants for P in soils of which the most important are Bray 1, Ambic 1, Bray 2, Truog and Olsen. The fertilizer industry prefers to use Bray 1 extractions for fertilization recommendations and the...
  10. The effects of spatial variation of certain soil properties on the winter yield of a lucerne stand

    The effects of spatial variation of certain soil properties on the winter yield of a lucerne stand

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    In general, agricultural fields are managed as uniform units, ignoring spatial soil heterogeneity and its effects on growth and yield of field crops. This study was conducted from June 2001—February 2002 and examines the effects of spatial variation of soil...
