  1. The Effects of Phosphate Fertilizers and Manure on Maize Yields in South Western Kenya

    The Effects of Phosphate Fertilizers and Manure on Maize Yields in South Western Kenya

    Item type: Journal Article • Journal: East African Agricultural and Forestry Journal
    Phosphorus, nitrogen and Striga hermonthica are the major constraints to maize production in the Nyanza Province of Kenya. Field trials were conducted on-farm in Nyanza Province to investigate the effects of phosphate fertilizers and manure on maize yields. The experimental...
  2. Preferential utilization of pans by springbok <em>(Antidorcas marsupialis)</em>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Forage utilization by springbok in pans and surrounding habitats was compared at one karroid shrubland site and two desert grassland sites and was found to be greater in pans than on adjacent plains and dunes. Springbok used pan areas for...
  3. The influence of lime and phosphorus on the growth of white clover on highly weathered Natal soils

    The influence of lime and phosphorus on the growth of white clover on highly weathered Natal soils

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Results of field studies conducted on highly weathered Natal soils in which the performance of white clover (Trifolium repens cv. Regal ladino) was examined under a range of lime and P treatments applied in factorial combination, are presented. Despite adverse...
  4. Behaviour of sesquioxic clay soils subjected to alkaline and saline effluents

    Behaviour of sesquioxic clay soils subjected to alkaline and saline effluents

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The effects of disposal of alkaline and saline effluents on sesquioxic red clay soils have been monitored for many years on a site in the eastern Transvaal. Recently a high chloride content effluent with a sodium adsorption ratio (SAR) of...
  5. Anorganiese stikstof in mieliegronde van die Oranje-Vrystaat en Transvaal met planttyd, 1984

    Anorganiese stikstof in mieliegronde van die Oranje-Vrystaat en Transvaal met planttyd, 1984

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Ondersoek is ingestel na die hoeveelheid anorganiese stikstof wat met planttyd gedurende die 1984/85-seisoen in mieliegronde van die Oranje-Vrystaat en Transvaal teenwoordig was. By 82 lokaliteite, wat verspreid oor hierdie gebied voorkom, is grondmonsters ingesamel. Grondmonsters is op 300 mm...
  6. Sodicity phenomena in red sesquioxic clay subsoils

    Sodicity phenomena in red sesquioxic clay subsoils

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Monitoring for many years of the soils of an effluent disposal site in the eastern Transvaal has shown that the disposal of alkaline and saline effluents on red sesquioxic clays has not appreciably affected soil permeability but has brought about...
  7. Effect of application methods on ammonia volatilization from soils in a controlled environment

    Effect of application methods on ammonia volatilization from soils in a controlled environment

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The objective of this investigation was to compare different application methods whereby ammonia losses from nitrogen fertilizers can be limited when applied to alkaline soils. Three application methods were simulated, namely broadcasting, ploughing under and band placement. Five nitrogen fertilizers,...
  8. Improving the isolation of actinomycetes from soil by high-speed homogenization

    Improving the isolation of actinomycetes from soil by high-speed homogenization

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Quantitative isolation of actinomycetes from five South African soils with different physical and chemical properties was conducted by hammer-mill comminution followed by high-speed liquid homogenization of resultant soil particles using a shaft homogenizer. Soil homogenates were serially diluted and plated...
  9. A comparison beween short-term chemical and biological methods to measure phosphorus availability in sludge-amended sesquioxic soils

    A comparison beween short-term chemical and biological methods to measure phosphorus availability in sludge-amended sesquioxic soils

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Due to the transformations which sludge undergoes after addition to soil, single measurements of P availability are of little value in soils which have recently received additions of sewage sludge. This study assessed six procedures on two soils—a clay of...
  10. '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...
