Soluble constituents and ion exchange reactions of Champlain sea sediments.

Laventure, Reginald S. January 1964 (has links)
The Champlain Sea sediments are the parent materials of some of the most important agricultural soils of Quebec. They contain a high proportion of clay-size particles which are primary minerals derived from igneous and metamorphic rocks. The mineralogy and mode of deposition give rise to unusual properties. The physical properties of these sediments have stimulated many studies of their geotechnical properties but only limited information is available for chemical properties. [...]

Exchange of sodium on clay minerals by leaching with calcium sulphate.

Chaudhry, Ghulam Haider. January 1965 (has links)
Accumulation of sodium in soil is a serious problem in arid and semi-arid regions of the world. Millions of acres of once fertile land have been thrown out of cultivation and-millions more are being added every year. The magnitude of the problem can be visualized from the fact that in Alberta alone 10 million acres are either seriously or partially affected by excess salinity and/or exchangeable sodium. In West Pakistan 100,000 acres go out of cultivation annually because of this menace and in the United States, out of 300 million acres under irrigation, between 25 and 30 percent are affected to varying degrees.
