Soil optimisation using zeolite

Evaluating Green Compost and Zeolite to Enhance Soil Quality for Dubai Sustainable City Language: English Thematic Areas: Natural Resources Management in Marginal Environments Problem Overview: In the United Arab Emirates, the soils are dominantly sandy and infertile and require frequent irrigation to maintain a healthy landscape under hot climate. However, little has been done in this respect on UAE soils for urban landscaping projects such as Dubai Sustainability City, and hence this subject has formed the focus of this study, involving zeolite and compost produced by Tadweer Waste Treatment L.L.C. in different quantities, tested in the laboratory and greenhouse trial. ...

Frederick A. Mumpton, Department of Earth Sciences, State University College, Brockport, NY 14420 Introduction As agriculturalists around the world step up their efforts to expand crop and livestock production, increasing attention is being paid to various mineral materials as soil amendments and as dietary supplements in animal husbandry. The close relationship between the agricultural and geological sciences is not new—crop production depends on the existence and maintenance of fertile soil, and agronomists rely on knowledge of the mineralogy and geochemistry of clays and other soil constituents. In animal sciences, the addition of crushed limestone to chicken feed to strengthen eggshells ... Read more

Ward Chesworth, Peter Van Straaten, Peter Smith, Steven Sadura Department of Land Resource Science, University of Guelph, Guelph, Ont. N1G 2W1 Canada Accepted 11 February 1987, Available online 1 April 2003 Abstract The various forms of apatite release Ca+2 and P-bearing anions into solution. The generally low solubility of these phases, however, has been a drawback to the use of apatite as a direct source of nutrient P in agriculture. Apatite has for the most part been used as a raw material for the production of the more soluble phases used in conventional fertilizers. This necessitates industrial processing by such techniques ... Read more
