Pot and field experiments were conducted to determine the nutrient requirements of Stylosanthes hamata growing on a euchrozem near Charters Towers in the semi-arid tropics of north-eastern Queensland. In pot experiments, significant responses were obtained to sulphur, phosphorus and copper; there was also a significant lime × sulphur interaction. However in the field, there was a significant response to sulphur only. The yield responses to sulphur applied in previous years suggest a considerable residual value for applied sulphur on this soil.
