Common use of Water Quality Clause in Contracts

Water Quality. Controlling erosion and the resulting sediment discharge helps to control phosphorous (P) discharge to waterways. This can be done with good pasture cover by managing stock type and grazing practice, to prevent bare patches and minimise soil loss. The construction and maintenance of water diversions from tracks to manage stormwater into sumps or onto pasture is recommended. Riparian strips with strong vegetation cover filter sediment to minimise sediment discharge to ephemeral waterways during storm events. Wetland or xxxxx areas managed as riparian/filter zones are useful for controlling nitrogen (N) discharge, which can occur through overland and groundwater flows. Other options for controlling N discharge include split fertiliser applications when applying urea, utilisation of dairy shed effluent, use of feed/standing pads and reduced stocking rates during winter. Direct application of fertiliser to waterways should be avoided, while fertiliser application rates and timing should be optimised for maximum pasture uptake and minimum leaching/runoff. A property nutrient budget is recommended to calculate the rates of nitrate leaching and phosphorus runoff, and regular soil testing should be undertaken to monitor changes in soil nutrient levels over time. In general it is recommended that fertiliser use and application is undertaken in accordance with industry best practice and management advice is available from the following source: • Waikato Regional Council Catchment Management Officer at the local Waikato Regional Council Office, • Code of Practice for Fertiliser Use – Pastoral Farming Guide.
