Profile features


                     Luvisols are moderately deep, dark brown in the topsoils.
            Below the ochric horizon, many Luvisols have a weak albic horizon,

            as indicated by a lighter colour and coarser, with blocky structure.
            The argic horizon typically may have a strong prismatic structure upon

            which thin clay skins can be seen.


            Environment and landforms


                     Normally, Luvisols occur in warm and cool temperate zones where there are moderate

            rainfall and a discrete dry season. These soils are found on gently undulating or flat land.
            The formation of Luvisols is preferred by a dry season during with the soil can crack, thereby

            permitting the transport of clay suspension in the following wet season. The development of
            Luvisols is based on a wide range of parent materials, which may not be associated. These

            materials include glacial materials, alluvial and colluvial deposits.


            Use and management


                     Most Luvisols are fertile soils and suitable for various agricultural uses. Luvisols with high

            silt content are susceptible to structural degradation when they are wet or over by heavy
            machinery. Luvisols on steep slopes require a measure of soil and water conservation.

            In places, the dense subsoil is caused by reducing conditions with stagnic properties.
