Introduction
High levels of potassium ([K.sup.+]) in soils are believed to degrade soil structure, and plant production is reduced because the physical fertility of the soil is diminished. Piggery effluent has relatively high concentrations of [K.sup.+] (Kruger et al. 1995; Biswas et al. 1999), and we were commissioned to determine levels of [K.sup.+] in piggery waste and to see if general patterns of chemical and physical consequences of its application to soil might be discerned across a range of soils and climates from south-eastern Queensland to south-eastern South Australia. Redding et al. (2002) surveyed land management of agricultural, and specifically ...
