Therefore, we decided to monitor soil Ba concentrations from a dryland wheat (<jats:italic>Triticum aestivum<\/jats:italic> L.)\u2013fallow agroecosystem experiment. This experiment received 10 biennial biosolids applications (1982\u20132003) at rates from 0 to 26.8 dry Mg ha<jats:sup>\u22121<\/jats:sup> per application year. The study was conducted on a Platner loam (Aridic Paleustoll), \u223c30 km east of Brighton, CO. Total soil Ba, as measured by 4 <jats:italic>M<\/jats:italic> HNO<jats:sub>3<\/jats:sub>, increased with increasing biosolids application rate. In the soil\u2010extraction data from 1988 to 2003, however, we observed significant (<jats:italic>P<\/jats:italic> &lt; 0.10) linear or exponential declines in ammonium bicarbonate\u2013diethylenetriaminepentaacetic acid (AB\u2013DTPA) extractable Ba concentrations as a function of increasing biosolids application rates. This was observed in 6 of 7 and 3 of 7 yr for the 0\u2010 to 20\u2010 and 20\u2010 to 60\u2010cm soil depths, respectively. Results suggest that while total soil Ba increased as a result of biosolids application with time, the mineral form of Ba was present in forms not extractable with AB\u2013DTPA. Scanning electron microscopy using energy dispersive spectroscopy verified soil Ba\u2013S compounds in the soil surface, probably BaSO<jats:sub>4<\/jats:sub> Wet chemistry sequential extraction suggested BaCO<jats:sub>3<\/jats:sub> precipitation was increasing in the soil subsurface. Our research showed that biosolids application may increase total soil Ba, but soil Ba precipitates are insoluble and should not be an environmental concern in similar soils under similar climatic and management conditions.<\/jats:p>","DOI":"10.2134\/jeq2006.0076","type":"journal-article","created":{"date-parts":[[2006,10,27]],"date-time":"2006-10-27T21:12:00Z","timestamp":1161983520000},"page":"2333-2341","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Biosolids Affect Soil Barium in a Dryland Wheat Agroecosystem"],"prefix":"10.1002","volume":"35","author":[{"given":"J.
