  1. 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...
  2. Responses of four perennial pasture legumes to soil amendment with lime and superphosphate

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Yield response of crownvetch (Coronilla varia) cv. Penngift, lucerne (Medicago sativa) cv. CUF 101, white clover (Trifolium repens) Dusi type and Kenya white clover (T. semipilosum) cv. Safari to differential application of lime and superphosphate were determined in a 5...
  3. Lime and phosphorus effects on the dry matter production of <em>eragrostis curvula</em> on dystrophic clay soils

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    The dry matter yield responses of Eragrostis curvula to P and lime over two seasons on Balmoral and Balgowan soil series in the Natal Mistbelt are discussed. With this work forming part of a study aimed at characterizing P fixation...
  4. Relations between soil factors and herbage yields of natural grassland on sandy soils in the south‐eastern Transvaal

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Forty systematically‐placed observation points were established in a 1.5‐ha area of floristically unifoim veld in which productivity varied spatially. At each point grass yields were determined by harvesting quadrats at eight‐week intervals during the growing season, and the volumetric water...
  5. A field evaluation of the differential tolerance to soil acidity of forty-eight South African maize cultivars

    A field evaluation of the differential tolerance to soil acidity of forty-eight South African maize cultivars

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    A field experiment was conducted on a Normandien clay loam (Plinthic Paleudult) to compare the acid tolerance of 48 commercially grown maize (Zea mays L.) cultivars. Cultivars were compared in terms of grain yield, plant height and leaf Al content...
  6. 'n Vergelyking van verskillende metodes vir die ekstraksie en bepaling van aluminium in grond

    'n Vergelyking van verskillende metodes vir die ekstraksie en bepaling van aluminium in grond

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Vier metodes vir die ekstrahering en bepaling van Al in suur gronde is vergelyk vir grondmonsters vanaf 'n verskeidenheid van bronne en met pH (KCl) waardes tussen 3,3 en 4,4. Die oogmerk was om 'n vinnige, eenvoudige, maar steeds betroubare...
  7. Comparison of aluminium, basic cations and acidity in the soil of indigenous forests and pine stands in the southern Cape

    Comparison of aluminium, basic cations and acidity in the soil of indigenous forests and pine stands in the southern Cape

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Litter and topsoil were sampled in plantations of Pinus elliottii and Pinus taeda and in adjacent indigenous forest in three different locations in the southern Cape, to study some of the effects on the soil of the establishment of pine...
  8. The use of a sewage sludge as a fertilizer for wheat in a glasshouse pot experiment

    The use of a sewage sludge as a fertilizer for wheat in a glasshouse pot experiment

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Acid soil infertility is a major limiting factor in crop production on soils along the eastern seaboard of South Africa. Invariably this problem is addressed by effectively liming the topsoil with little influence on subsoil acidity. A study was conducted...
  9. Die invloed van grondsuurheid op koringkultivars (<em>Triticum aestivum</em> L.) met verskillende vlakke van aluminiumverdraagsaamheid in die Oos-Vrystaat. II. Wortelontwikkeling

    Die invloed van grondsuurheid op koringkultivars (<em>Triticum aestivum</em> L.) met verskillende vlakke van aluminiumverdraagsaamheid in die Oos-Vrystaat. II. Wortelontwikkeling

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    'n Veldproef is uitgevoer in die Oos-Vrystaat om te bepaal of kultivars wat verskil in aluminium (Al)-verdraagsaamheid ook verskil in wortelontwikkeling by verskillende grondsuurheidsvlakke. Drie kultivars wat varleër in Al-verdraagsaamheid is by vier grondsuurheidsvlakke in 'n verdeelde-perseelontwerp getoets. Die twee...
  10. Relationship between acid saturation and hydrogen activity of soils from different districts in South Africa

    Relationship between acid saturation and hydrogen activity of soils from different districts in South Africa

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Soil analyses results from six districts in the western maize producing areas of South Africa were used for correlating exchangeable acidity and acid saturation with hydrogen ion activity (pH). From the resulting regression equations, the pH values that corresponded with...
