These soils have a high clay content and are naturally very fertile with an ability to store water like a sponge. Rain which falls during the fallow period is absorbed and stored in the soil profile, held against gravity. This moisture is then accesed by the next crop to be grown in the rotation, reducing the reliance on in-crop rainfall. It is these characteristics of the soil, coupled with vast amounts of high quality underground water and an idilic climate, which make the region one of the most productive and reliable cropping regions in Australia, consistently achieving yields above the national average. The main crops grown include wheat, barley, chickpeas, faba beans, canola, sorghum, sunflowers, mung beans, maize, soybeans and cotton.
Livestock production also forms an important part of the agicultural production and takes place mainly on the ridges and hills interspersed throughout the floodplains. This consists mainly of beef cattle and sheep for both wool and prime lamb. The two major supermarkets source a considerble portion of their NSW requirements from the Liverpool Plains region not to mention butchers and restaurants throughout the state.
