• Influence of organic matter, clay mineralogy, and pH on the effects of CROSS on soil structure is related to the zeta potential of the dispersed clay

  Authors:Alia Marchuk, Pichu Rengasamy, and Ann McNeillFrom:Soil Research (Vol. 51, Issue 1) Peer-Reviewed

  Feb. 20134,247 words Report 1560LThe high proportion of adsorbed monovalent cations in soils in relation to divalent cations affects soil structural stability in salt-affected soils. Cationic effects on soil structure depend on the ionic strength of...

• Soil structure degradation and mellowing of compacted soils by saline-sodic solutions

  Authors:A. Rahman Barzegar, J. Malcolm Oades, and Pichu RengasamyFrom:Soil Science Society of America Journal (Vol. 60, Issue 2) Peer-Reviewed

• Possible effects of irrigation with wastewater on the clay mineralogy of some Australian clayey soils: laboratory study

  Authors:Serhiy Marchuk, Jock Churchman, and Pichu RengasamyFrom:Soil Research (Vol. 54, Issue 7) Peer-Reviewed

  Oct. 20167,020 words Report 1460LPotassium is common in a wide variety of wastewaters and in some wastewaters is present at several hundred to several thousand mg [L.sup.-1]. Potassium is taken up by expandable clays leading to its fixation and...

• Nature of the clay-cation bond affects soil structure as verified by X-ray computed tomography

  Authors:Alla Marchuk, Pichu Rengasamy, Ann McNeill, and Anupama KumarFrom:Soil Research (Vol. 50, Issue 8) Peer-Reviewed

  Nov. 20124,648 words Report 1580LNon-destructive X-ray computed tomography ([micro]CT) scanning was used to characterise changes in pore architecture as influenced by the proportion of cations (Na, K, Mg, or Ca) bonded to soil particles. These observed...

• Organic matter, sodicity, and clay type: influence on soil aggregation

• Threshold electrolyte concentration and dispersive potential in relation to CROSS in dispersive soils

  Authors:Alla Marchuk and Pichu RengasamyFrom:Soil Research (Vol. 50, Issue 6) Peer-Reviewed

  Sept. 20124,741 words Report 1580LWe have used the newly developed concept of CROSS (cation ratio of soil structural stability) instead of SAR (sodium adsorption ratio) in our study on dispersive soils. CROSS incorporates the differential dispersive...

• Cation ratio of soil structural stability (CROSS)

  Authors:Pichu Rengasamy and Alla MarchukFrom:Soil Research (Vol. 49, Issue 3) Peer-Reviewed

  May 20113,929 words Report 1510LSodium salts tend to dominate salt-affected soils and groundwater in Australia; therefore, sodium adsorption ratio (SAR) is used to parameterise soil sodicity and the effects of sodium on soil structure. However, some...

• Osmotic and ionic effects of various electrolytes on the growth of wheat

  Author:Pichu RengasamyFrom:Australian Journal of Soil Research (Vol. 48, Issue 2) Peer-Reviewed

  Mar. 20103,305 words Report Pot experiments were conducted using a sandy loam soil and various electrolyte solutions such as NaCl, CaCl2, [Na.sub.2]S[O.sub.4], and Hoagland nutrient solution containing all macro- and micro-nutrient elements in...
