Representative coal samples from UK major coal fields were also determined for \u03b4<jats:sup>34<\/jats:sup>S. Concentrations of S showed no clear trends in either grain or straw over the 155 years from 1845 to 1999. However, grain and straw \u03b4<jats:sup>34<\/jats:sup>S decreased rapidly from 6 to 7\u2030 in 1845 to \u22122 to \u22125\u2030 in the early 1970s, and since then have increased to 0.5 to 2\u2030 in the late 1990s. This pattern mirrored the trend of UK SO<jats:sub>2<\/jats:sub> emissions over the 155 years. Both grain and straw \u03b4<jats:sup>34<\/jats:sup>S correlated strongly and negatively with UK SO<jats:sub>2<\/jats:sub> emissions (<jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup> &gt; 0.89), but the relationships were different for the pre\u2010 and post\u20101970 data sets. Soil \u03b4<jats:sup>34<\/jats:sup>S also decreased considerably, from 8.2\u2030 in 1865 to 3.7 to 4.5\u2030 during 1965\u20131999. A negative \u03b4<jats:sup>34<\/jats:sup>S value was inferred for the anthropogenic S deposited at the experimental site before 1970, and further confirmed by negative \u03b4<jats:sup>34<\/jats:sup>S values (\u22126 to \u221210\u2030) found in the coal samples from southeastern England and southern Wales. Based on the S isotope ratios, we estimated that anthropogenic S contributed 62 to 78% of the S uptake by wheat at the peak of SO<jats:sub>2<\/jats:sub> emissions, and accounted for 28 to 37% of the topsoil S in 1965.<\/jats:p>","DOI":"10.2134\/jeq2003.3300","type":"journal-article","created":{"date-parts":[[2012,8,2]],"date-time":"2012-08-02T11:52:42Z","timestamp":1343908362000},"page":"33-39","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":42,"title":["Stable Sulfur Isotope Ratio Indicates Long\u2010Term Changes in Sulfur Deposition in the Broadbalk Experiment since 1845"],"prefix":"10.1002","volume":"32","author":[{"given":"F.
