Abstract
Soil solution and solid phase analyses were compared for stubble standing and stubble burnt systems on an acid, acidified and limed Alfisol in north-eastern Victoria. Exchangeable (1 M KCl) aluminium (Al), soil solution total and monomeric Al, pH (water) and soil solution pH were measured to identify any differences in soil acidification between the stubble burnt and the stubble standing treatments. All measures of Al increased with soil depth down to 10 cm in all stubble treatments and decreased in the 10–20 cm soil depth with the exception of lime treatments. Concentrations of low molecular weight organic acids in the soil solution were determined by high pressure liquid chromatography (HPLC). Aromatic and aliphatic acids were distributed throughout the soil depth (0–20 cm) for the stubble standing treatments but were confined to the 0–5 cm soil depth for the stubble burnt treatment. In this short term field trial (2 years for stubble management), the data suggest that the conventional practice of stubble burning was more acidifying than the soil conservation practice of stubble standing, over the 0–20 cm soil depth for the lime (6 t ha-1) treatments.
