Land managers with paddocks that are prone
to waterlogging, poor crop or pasture
emergence, gully erosion or tunnel erosion may
be experiencing the effects of sodicity.Sodicity
becomes a problem when there is sufficient
sodium attached to the clay in the soil to affect
soil structure. These soils are referred to as
sodic and are often regarded as poorly
structured and difficult to manage, and are
susceptible to soil degradation such as erosion.
In Australia about 30% of the agricultural land
is sodic. That is about five times the area of
land that is estimated to be saline.
Not all poorl y structured soils are sodic. Land
managers need to distinguish between poorly
stru tured non-sodic soils and sodic soils as
management differs for each situation.
