Extract

The deposition on soil of sulphur from the atmosphere through gaseous absorption, or particulate precipitation and deposition on vegetation and to other surfaces, is calculated to account for most of the atmospheric-S deposited in Britain; S collected in rainwater appears to amount to only one-sixth of the total deposition (Chamberlain, 1960). A knowledge of the amounts of S deposited is important agriculturally, particularly in areas far from industry, both where fertilizers are not used, and also when deciding how much fertilizer-S should be used relative to other nutrients. The technical problems of separating the amounts of sulphur deposited by gaseous absorption, particulate precipitation, and in rain are easier in a tropical climate which has well-defined wet and dry seasons and where atmospheric SO2 concentrations are smaller and vary less than in industrial areas.
