Impact of FarmingImproperly managed agricultural activities may impact surface water by contributing nutrients, pesticides, sediment and bacteria, or by altering stream flow. Fertiliser and pesticide use, tillage, irrigation and poor drainage can affect water quality and hydrology.

EutrophicationFarmers apply nutrients on their fields in the form of chemical fertilisers and animal manure, which provide crops with the nitrogen and phosphorous needed to grow. Leaching and run-off into the groundwater and streams can pollute streams resulting in eutrophication and loss of freshwater stream biodiversity

Good Farming PracticeA big part of marketing our agricultural products is our high standards and clean green image. Regional Councils, Forest and Bird and other Stake-holders are encouraging Farmers to keep NZ Streams clean.
