  1. Effects of phosphate carrier, phosphate placement, and level of lime application on plant growth on two oxisols in natal*

    Effects of phosphate carrier, phosphate placement, and level of lime application on plant growth on two oxisols in natal*

    A glass‐house study on two Oxisols revealed a marked response by trudan (Sorghum sudanense) to phosphate (P) placement. Plant response to water‐soluble forms of P (superphosphate and superphosphate lime mixture) was greater when this phosphale was granulated or when it...
  2. Use of annual production curves of pasture species in pasture planning

    Use of annual production curves of pasture species in pasture planning

    A method is suggested whereby the annual production curves of pasture species can be used to assist in choosing species best suited to a particular farming enterprise, and to determine the area to be planted to each species. This approach...
  3. Growth responses of <em>Eucalyptus globulus</em> and <em>E. nitens</em> to pruning and fertiliser treatments in a plantation managed for solid-wood products

    Growth responses of <em>Eucalyptus globulus</em> and <em>E. nitens</em> to pruning and fertiliser treatments in a plantation managed for solid-wood products

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    The responses of Eucalyptus globulus and E. nitens to pruning (removal of 0 or 60% of the green crown depth) in two lifts and nitrogen (N) fertiliser application (0 [N0], 100 [N1], 300 [N3] and 500 [N5] kg N ha–1)...
  4. Solid-wood production from temperate eucalypt plantations: a Tasmanian case study

    Solid-wood production from temperate eucalypt plantations: a Tasmanian case study

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Since 1988, there has been a major focus in Tasmania on research for the management of temperate eucalypt plantations for solid wood. This coincided with the formal transfer of large areas of native forest that had previously been part of...
