Management considerations | ||||
The lunette soils in the Victorian Volcanic Plain may have sandy or clay profiles, with clay profiles, as in this case (SFS21), being generally more common. Occurrence is very localised and of limited spatial extent. The soils are well structured and have high fertility. Site drainage is usually good but because the clay content is high and the clays swell, internal drainage is often poor and the soil surface becomes sticky and difficult to manage when wet. |
