Description :
Results from the measurement of microweight loss of Magnesian Limestone rock tablets placed at the soil-bedrock interface on a hillslope over 10 years (1982-1992) gave the same relative pattern of upslope increase in weight loss as did short-term measurements (1979-1981). Microweighed rock tablets may therefore give unreliable absolute rates and can only be used to indicate relative spatial differences rather than to give reliable data on temporal changes.
