The landscape and marginal cropping lands — inherent and induced
Natural Resources and Water, Toowoomba, Queensland, Australia
Marginal cropping soils in Queensland are defined by one or more limiting landscape, pedological or climatic factors interacting with agronomic requirements. Limitations may be inherent in the landscape or induced by farming activities. Common limitations include subsoil sodicity/ salinity, low moisture availability and poor surface condition. The latter is often exacerbated by poor management practices.
