potential root depth
potential root depth
Potential depth of the soil profile where roots develop (in cm).
Potential depth of the soil profile where roots develop (in cm).
This depth must take in account the presence of obstacle to roots. 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
