Net Mineralization Rate of Selenium from Plant Material and Inorganic Salts
Selenium (Se) is an essential nutrient for animals,humans and microorganisms. The importance of se in the prevention,as well as the treatment,of chronic and degenerative diseases in humans has been established (Rayman,2000).In large parts of the world se availability in soils is very low. Thus,crops produced in these areas may have very low Se concentrations (Oldfield,2002).In order to increase the average Se intake,Se-enriched mineral fertilizers have been used in crop production (White and Broadley,2009).However,only a limited amount of added se is absorbed by crops (Hambuckers,2008).Most of the published studies on Se transformations in soil have been carried out at high concentrations.It is still not fully understood if changes in soil environmental factors may cause mobilization of previously applied se. Therefore,it may be safer to find an alternative se source that is more bioavailable than Se in inorganic fertilizers.
