Description

Rates of soil erosion in grazing lands of north Queensland were measured at 3 sites over 3 years. Within years, soil loss was highest during summer, even though rainfall was often higher in autumn than in summer. This pattern is explained by lower cover and higher rainfall intensities during summer than autumn. Grazing management should aim at having sufficient cover at the end of the dry season (September-October) to prevent soil loss from high intensity storm rains common at this time of year.
