Abstract

This paper investigates the effects of landscape recontouring on soil morphology, topsoil organic matter, and soil and water salinisation on a vineyard site in the Awatere Valley of the Marlborough region, in the NE of New Zealand's South Island. Soil pits in representative locations in the virgin and recontoured landscapes were opened for profile comparison. No significant differences in topsoil organic C and N were found between recontoured and virgin landscapes. Diffuse throughflow in infilled gullies was found to be causing accumulations of salts in an irrigation pond to levels likely to be negative for viticulture. Immediate negative effects for viticulture in the disturbed soil appear to be low, as ersatz soil profiles were reconstructed after recontouring had taken place and the topsoil was well preserved. As this process is widespread in the region, concern is primarily for salinisation potential of throughflow and receiving waters
