  1. 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...
  2. The influence of different forms and concentrations of nitrogen on the growth and metabolism of <em>digitaria eriantha</em> and <em>chloris Gayana</em> grown under saline conditions

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Chloris gayana and Digitaria eriantha plants were watered with nutrient media containing a high concentration of sodium chloride (150 mM) and either high (200 mg/l) or low (25 mg/l) concentrations of nitrate nitrogen and ammonium nitrogen. Dry mass and leaf...
  3. The influence of nitrate and ammonium forms of nitrogen fertilizer on the growth and osmoregulation of <em>digitaria eriantha</em> and <em>Chloris gayana</em> grown under saline conditions

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Digltaria eriantha and Chloris gayana were grown under controlled conditions for three months and were treated with a nutrient solution containing 150 mMol NaCl and the following nitrogen sources: 25 or 200 mg/l NH4 +‐N or NO3 −‐N or no...
  4. Movement of ammonia plus ammonium from nitrogen fertilizers band placed in alkaline soils

    Movement of ammonia plus ammonium from nitrogen fertilizers band placed in alkaline soils

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Movement of NH3 plus NH4 + from nitrogen fertilizers, band placed either as crystals or as granules in alkaline soils, was determined. The pH values of these soils, whereof the clay contents ranged from 7,6 to 49,9%, were adjusted to...
  5. Voorspelling van nitraatbeweging in 'n fynsandleemgrond gedurende die braakperiode met die Burnsmodel

    Voorspelling van nitraatbeweging in 'n fynsandleemgrond gedurende die braakperiode met die Burnsmodel

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    'n Eenvoudige model wat deur Burns (1974) ontwikkel is vir die voorspelling van nitraatbeweging in sandtot sandleemgronde is getoets. Verskillende nitraatverspreidingspatrone is in 'n fynsandleemgrond van 1,5-m diepte tot stand gebring waarna water met mikrobesproeiing toegedien is om nitraatbeweging te...
  6. Controlling excessive growth in cotton by multiple applications of low concentrations of mepiquat chloride

    Controlling excessive growth in cotton by multiple applications of low concentrations of mepiquat chloride

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Excessive vegetative growth of cotton occurs under favourable growing conditions and this contributes to yield losses. Low concentrations of mepiquat chloride (1, 1-dimethylpiperidinium chloride) were applied to vigorous, growing cotton by means of two or more sprays at different time...
  7. An automated colorimetric method for the determination of dicyandiamide in 1.0 M KCI soil extracts

    An automated colorimetric method for the determination of dicyandiamide in 1.0 M KCI soil extracts

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The nitrification inhibitor dicyandiamide (cyanoguanidine, didin or DCD) reacts with 1-naphthol and diacetyl to form a red complex which measures spectrophotometrically at 540 nm. An automated analytical procedure was developed to determine DCD in soils extracted with 1.0 M KCI...
  8. Die gebruik van groeireguleerders om die blomperiode van katoen te wysig

    Die gebruik van groeireguleerders om die blomperiode van katoen te wysig

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Katoengebiede in Suid-Afrika, hoër as 950 m bo seevlak, het 'n kort groeiseisoen indien laat in November geplant word. Die bydrae van groeireguleerders en verbouings praktyke om rypwording van laat geplante katoen te verhaas en die uitwerking daarvan op veselgehalte,...
  9. The effect of chloride on four different citrus rootstocks

    The effect of chloride on four different citrus rootstocks

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Seedlings of Troyer citrange [Poncirus Mollata L. Raf. × Citrus sinensis L. Osbeck] (Tro), Citrus volkameriana (Vol), Carrizo citrange [Poncirus trifoliata L. Raf. × Citrus sinensis L. Osbeck], (Car) and Rough lemon [Citrus jambhiri Lush.] (Rie) were tested for tolerance...
  10. Effects of sodium sulphate, sodium chloride and manganese sulphate on kikuyu (<em>Pennisetum clandestinum)</em> growth and ion uptake

    Effects of sodium sulphate, sodium chloride and manganese sulphate on kikuyu (<em>Pennisetum clandestinum)</em> growth and ion uptake

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Irrigation with saline water is increasingly practised yet an understanding of plant response to different salt types remains largely elusive. Our study investigated the effects of irrigation with simulated effluent containing three salts on the growth and composition of a...
