Summary

The Br content of soils and herbage from sites in north-west Pembrokeshire was determined. Topsoils had a range of Br contents from 10 to 515 μg/g, with a mean of 54 μg/g, subsoils ranged from < 1 to 455 μg/g, mean 47 μg/g, and herbage samples from 5 to 157 μg/g, mean 45 μg/g.

The topsoil Br content can be related to the loss on ignition and drainage status of the soil; the topsoil Br/loss on ignition ratio becomes smaller with increasingly poor drainage. It was found that the Br distribution in the soil profile is also related to drainage status, the topsoil/subsoil Br ratio increasing with increasingly poor drainage.

There is no clear relationship between soil Br and the amount of the element taken up by the herbage at the same sites.
