• Description:
• Dry saline soils affect large areas of South Australia-s cropping land. Previous data indicates that 6.5 million hectares of cropping land are affected by transient salinity or dry saline land. This is salinity not associated with a rising water table bringing salts to the surface. Rather, dry saline land is caused by evaporation and ‘wicking- or capillary rise of water through the soil profile bringing salt to the surface (Department of Environment, Water and Natural Resources, 2016). The concentration of salts in the topsoil can also affect germination of sensitive crop types. The poor crop growth and cover of the soil as a result can see further evaporation and more salt drawn to the surface. Anecdotally, there are concerns that these areas are increasing across the landscape and affecting crop establishment and growth. This is particularly through the Upper Eyre Peninsula, Mid and Upper North and parts of the Mallee. Seasonal changes in the amount of rainfall received and evaporation, as well as reduced groundcover coming out of drought conditions can make these areas worse in a paddock and take an extended amount of time to ameliorate. A survey on the amount of dry saline land was conducted by Insight Extension for Agriculture and collected responses from growers across the Eyre Peninsula and Mallee in South Australia. This survey found that dry saline land is an increasing source of concern in these regions and across all respondents was responsible for an estimated $5 ...
