Extraction efficiency and the role of the extracts in causing soil water repellency was examined by determining extract mass, sample organic carbon content and water repellency (after drying at 20\u00b0C and 105\u00b0C) pre- and post-extraction, and amounts of aliphatic C\u2013H removed using DRIFT, and by assessing the ability of extracts to cause repellency in acid-washed sand (AWS).<\/jats:p>\n                  <jats:p>Key findings are: (i) none of organic carbon content, amount of aliphatic C\u2013H, or amount of material extracted give any significant correlation with repellency for this diverse range of soils; (ii) sample drying at 105\u00b0C is not necessarily useful before extraction, but may provide additional information on extraction effectiveness when used after extraction; (iii) the extraction removed repellency completely from 13 of the 15 repellent samples; (iv) extracts from all repellent and wettable control soils were capable of inducing repellency in AWS. The findings suggest that compounds responsible for repellency represent only a fraction of the extract composition and that their presence does not necessarily always cause repellency.<\/jats:p>","DOI":"10.1071\/sr04091","type":"journal-article","created":{"date-parts":[[2005,5,27]],"date-time":"2005-05-27T01:29:26Z","timestamp":1117157366000},"page":"225-237","source":"Crossref","is-referenced-by-count":134,"title":["Extraction of compounds associated with water repellency in sandy soils of different origin"],"prefix":"10.1071","volume":"43","author":[{"given":"S.
