• Soil carbon dynamics under different cropping and pasture management in temperate Australia: results of three long-term experiments

  Authors:K.Y. Chan, M.K. Conyers, G.D. Li, K.R. Helyar, G. Poile, A. Oates, et al.From:Soil Research (Vol. 49, Issue 4) Peer-Reviewed

  July 20116,671 words Report 1520LIn addition to its important influence on soil quality and therefore crop productivity, soil organic carbon (SOC) has also been identified as a possible C sink for sequestering atmospheric carbon dioxide. Limited data...

• The role of N transformations in the formation of acidic subsurface layers in stock urine patches

  Authors:J.R. Condon, A.S. Black, and M.K. ConyersFrom:Australian Journal of Soil Research (Vol. 42, Issue 2) Peer-Reviewed

  Mar. 20047,433 words Article This study examines the role of nitrogen transformations in the acidification of soil under stock urine patches, specifically the formation of acidic subsurface layers. These are horizontal planes of acidity several...

• Influence of moist--dry cycles on pH changes in surface soils

  Authors:K.I. Paul, A.S. Black, and M.K. ConyersFrom:Australian Journal of Soil Research (Vol. 37, Issue 6) Peer-Reviewed

  Nov. 19996,198 words Article Abstract It is well established that in the moderately acidic soils of southern Australia, the 0-2 cm layer commonly has a higher pH than soil layers between 2 and 10 cm depth. The surface 2 cm of soil is also...

• Soil carbon stocks under different pastures and pasture management in the higher rainfall areas of south-eastern Australia

  Authors:K.Y. Chan, A. Oates, G.D. Li, M.K. Conyers, R.J. Prangnell, G. Poile, et al.From:Australian Journal of Soil Research (Vol. 48, Issue 1) Peer-Reviewed

  Feb. 20106,383 words Report In Australia, pastures form the basis of the extensive livestock industries and are important components of crop rotation systems. Despite recent interest in the soil carbon sequestration value of pastures in the...

• Predicting the response of wheat (Triticum aestivum L.) to liquid and granular phosphorus fertilisers in Australian soils

  Authors:T.M. McBeath, M.J. McLaughlin, R.D. Armstrong, M. Bell, M.D.A. Bolland, M.K. Conyers, et al.From:Australian Journal of Soil Research (Vol. 45, Issue 6) Peer-Reviewed

  Sept. 20076,260 words Report 1690LLiquid forms of phosphorus (P) have been shown to be more effective than granular P for promoting cereal growth in alkaline soils with high levels of free calcium carbonate on Eyre Peninsula, South Australia. However,...

• Effect of ammonium, organic amendments, and plant growth on soil pH stratification

  Authors:C.M. Evans, M.K. Conyers, A.S. Black, and G.J. PoileFrom:Australian Journal of Soil Research (Vol. 36, Issue 4) Peer-Reviewed

  July-August 19985,707 words Article We studied the development of soil layers of different pH (strata) within the surface 10 cm of soil. Substrates which affect nitrogen transformations (ammonium sulfate, sucrose, and lucerne hay) were added to the soil to...

• Comparison of three carbon determination methods on naturally occurring substrates and the implication for the quantification of 'soil carbon'

  Authors:M.K. Conyers, G.J. Poile, A.A. Oates, D. Waters, and K.Y. ChanFrom:Soil Research (Vol. 49, Issue 1) Peer-Reviewed

  Feb. 20114,637 words Report 1360LAccounting for carbon (C) in soil will require a degree of precision sufficient to permit an assessment of any trend through time. Soil can contain many chemically and physically diverse forms of organic and inorganic...

• The influence of potassium and defoliation of ryegrass on the formation of acidic subsurface layers in stock urine patches

  Authors:J.R. Condon, A.S. Black, and M.K. ConyersFrom:Australian Journal of Soil Research (Vol. 43, Issue 2) Peer-Reviewed

  Mar. 20058,017 words Article This study examined the influence of simulated urine solutions containing various KCI and urea-N rates on the formation of acidic subsurface layers in soil columns. A factorial design was implemented with application...

• Modelling the effects of soil properties on the concentration of Cd extracted by 10mM Ca[Cl.sub.2] from soils of the Sydney Basin

  Authors:P.J. Milham, K.B.P.N. Jinadasa, D. Collins, P.J. Nicholls, C.A. Hawkins, R.G. Wenzel, et al.From:Australian Journal of Soil Research (Vol. 42, Issue 7) Peer-Reviewed

  Dec. 200412,200 words Article Undisturbed surface soils on the peri-urban fringe of the Sydney Basin are mostly acidic, with low concentrations of total cadmium ([Cd.sub.t]) and a wide range of other properties. In taxonomically similar soils on...

• The distribution of net nitrogen mineralisation within surface soil. 1. Field studies under a wheat crop

  Authors:Erry Purnomo, A. S. Black, C. J. Smith, and M. K. ConyersFrom:Australian Journal of Soil Research (Vol. 38, Issue 1) Peer-Reviewed

  Jan. 20005,327 words Article To test the hypothesis that net nitrogen (N) mineralisation is concentrated in the surface few centimetres following minimal soil disturbance for crop establishment, mineralisation was measured during the growth of...

• The distribution of net nitrogen mineralisation within surface soil. 2. Factors influencing the distribution of net N mineralisation

  Authors:Erry Purnomo, A. S. Black, and M. K. ConyersFrom:Australian Journal of Soil Research (Vol. 38, Issue 3) Peer-Reviewed

  May 20004,507 words Article This investigation examined the magnitude of gradients in net nitrogen (N) mineralisation through the surface 20 cm of soils used for cropping, and factors influencing these gradients. Soils used were W (Red Kandosol)...
