  1. Effects of soil compaction on pasture growth during rehabilitation of strip‐mined land

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Compaction of soils by heavy earthmoving equipment is an endemic problem in the rehabilitation of land after strip‐mining. Accordingly, special tillage operations and other precautions to reduce the severity of compaction are practised on strip coal mines of the Anglo...
  2. Soil-water conservation as affected by primary tillage practices

    Soil-water conservation as affected by primary tillage practices

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    An investigation of water conservation as affected by different primary tillage methods was conducted on a soil of the Doveton series (fine-loamy, mixed, thermic family of Rhodic Paleudults), where a direct sampling technique was used to monitor the soil-water profiles...

  4. The effect of tillage system on lodging in maize resulting from a severe rainstorm

    The effect of tillage system on lodging in maize resulting from a severe rainstorm

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Severe lodging in maize lands on Cedara on the 24 February 1985 was caused by a rainstorm registering Force 10 on the Beaufort scale. Large differences in lodging existed between plots in three tillage trials. In two identical primary tillage...
  5. Water storage, soil temperatures and maize (<em>Zea mays</em> L.) growth for various tillage practices

    Water storage, soil temperatures and maize (<em>Zea mays</em> L.) growth for various tillage practices

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Four tillage treatments ranging from conventional mouldboard ploughing through to direct-drilling were repeated during the second season of an ongoing experiment. At commencement of the new season, differences in plant- available water (PAW) in the top 600 mm of the...
  6. The effect of tillage system and rate and time of nitrogen application on maize performance on a sandy Avalon soil

    The effect of tillage system and rate and time of nitrogen application on maize performance on a sandy Avalon soil

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Four nitrogen fertilizer regimes were superimposed on a tillage trial on a sandy Avalon soil at Dundee in 1985 in order to investigate whether the rate and time of N fertilizer application influenced the poor early-season growth and reduced yields...
  7. The effect of reduced tillage on soil organic carbon

    The effect of reduced tillage on soil organic carbon

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The organic carbon contents of the 0–15-cm and 15–30-cm layers of conventionally tilled, stubble-mulched and no-tilled soils were compared. Samples from four localities in the Transvaal and Orange Free State were analyzed for organic C by means of two methods...
  8. Die invloed van verskillende tipes en hoeveelhede plantresmateriaal op onkruiddodereffektiwiteit

    Die invloed van verskillende tipes en hoeveelhede plantresmateriaal op onkruiddodereffektiwiteit

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Die invloed van agt verskillende plantreshoeveelhede (0–3 500 kg ha−1), sowel as verskiHende tipes plantreste (graansorghum- en mieliereste) op onkruiddodereffektiwiteit is ondersoek in 'n glashuisproef. Onkruiddodereffektiwiteit is bepaal deur middel van 'n indikatorplant, Avena sativa. Droëmassaopbrengs en planttellings van die...
  9. The effect of tillage: maize residue interactions upon soil water storage

    The effect of tillage: maize residue interactions upon soil water storage

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Four months before planting a crop of maize, a study was commenced on a well-drained clay loam soil to test the effect of tillage and surface maize residue on soil water storage. Tillage main plots were split into bare (residue...
  10. 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
