Cane growers lead the pack on acid sulfate soils

By

Acid sulfate soils pose a major environmental problem in NSW coastal catchments. Acid sulfate soils (ASS) arc a feature of coastal lowlands and they affect farms through acidification of the soil and water, which degrades farmland and adjoining wetlands. Coastal NSW has between 0.4 and 0.6 million ha of sulfidic sediments. Therefore, it is important that every landholder on the floodplain be aware of ASS, their identification and appropriate management strategies. This survey aimed to assess the extent of understanding of ASS and of the management strategies actually undertaken. To understand how farmers are dealing with this problem, 287 were surveyed in seven catchments prone to ASS. The four principal coastal industry groups, cane, tea tree, beef and dairy, were included. The sample included 105 cane growers from the Tweed, Richmond and Clarence catchments in northern NSW. All farmers were asked about socio-economic factors, acid sulfate soil indicators, awareness and sources of information. This paper concentrates on the contrasts between the sugarcane and beef industries. The sugarcane industry is cohesive, with stable commodity prices and confined to a 45 km proximity to the catchment's sugar processing mill. The authors found that cane growers have made acid sulfate soils a focus, and are ahead of other industries in awareness and knowledge levels. Cane growers feel in control of managing ASS. In contrast, beef farmers have no cohesive industry, receive low commodity prices, are geographically dispersed, and feel angry and threatened by acid sulfate soil problems. This paper shows the strength that a cohesive, focused, geographically close industry has over an industry that is dispersed and without an industry body.
