Location: Lillimur
Australian Soil Classification: Endocalcareous-Endohypersodic, Self-mulching, Grey VERTOSOL
Northcote Factual Key: Ug5.2
Great Soil Group: grey clay
General Landscape Description: Level plain. These cracking clay soils are often found in association with lakes or on plains between rises. This soil type is regarded as the most appropriate to represent the gently undulating clay plains land unit. A large area of these soils can be found around Neuarpur where irrigated white clover is grown for seed production.
