The New South Wales Branch of the Society selected the Red Chromosol as its State Soil.
Also known as red brown earths, red podzolic soils or red duplex soils, Red Chromosols feature a strong texture contrast between the A and B horizons. They are distinguished from other texture contrast soils by not being strongly acidic like Kurosols or sodic like Sodosols in their upper B horizons. In their natural condition, these soils have favourable physical and chemical properties, but many now have hardsetting surface layers with structural degradation and acidification problems caused by longterm cultivation.
They occupy some 20% of the State and are used for grazing, cropping and vineyards. They have been described as 'the workhorse of agriculture' in New South Wales.
