Legislation in the Republic of Ireland differentiates between gley and non-gley soils in relation to the size of pig farms requiring (i) environmental impact (EIS) statements for planning permission (ii) licensing (IPC licence). Pig farmers on gley soils require an EIS statement and an IPC licence for more than 1000 pig units; this is increased to 3000 pig units on non-gley soils with the soil type defined at the site of the farm buildings. The range and variation in gley soils in Ireland are outlined and the role of hydromorphic features in soil classification systems in various countries discussed. The hydrodynamics of gley soils are not well understood. It is recommended that the differentiation between soil types be dropped in a future revision of the legislation on planning and licensing pig farms. Suggestions on the subdivision of gley soils in soil surveys of the Irish counties remaining unsurveyed and for studies on their hydrodynamics are provided.
