Individual study: Addition of sulphur to agricultural fields to restore heathland, Trehill Farm, Pembrokeshire, Wales
Day J. (2005) Addition of sulphur to agricultural fields to restore heathland, Trehill Farm, Pembrokeshire, Wales. Conservation Evidence, 2, 86-88
Former arable fields were treated by removing the topsoil, adding sulphur and applying seed-rich cuttings of heather Calluna vulgaris, bell heather Erica cinerea and western gorse Ulex gallii using a muck spreader. After soil stripping an interesting plant community developed including some less frequent or rare species. Both heather species and western gorse germinated. Soil pH a year after the sulphur addition was 5.6 where applied at rate of 4t/ha and 4.2 where applied at 8t/ha.
