An obstacle can be: • a toxic layer resulting from low pH values and associated high concentrations of Al and heavy metals, or a high salt content, etc.; • a layer with few oxygen available for plant roots resulting from the presence of permanent or a perched water table, or the presence of a decomposing peat layer, etc; • a layer forming a mechanical obstacle like a hard rock, a petrocalcic horizon, etc.; • an impermeable layer such as a fragipan, an iron pan, clay layers in sediments or as result of pedogenesis. NOTE The potential root depth is a parameter to be taken into account for meeting the (i) Agri-environmental indicators that track the integration of environmental concerns into CAP at EU, national and regional levels
