The Demonstration Test Catchments (DTC) project is a joint Defra, Environment Agency (EA) and Welsh Assembly Government initiative working in three river catchments – the Wensum in Norfolk plus the Eden (Cumbria) and Avon (Hampshire).

The overall objective of the project is to provide evidence to test the hypothesis that it is possible to cost effectively reduce the impact of agricultural diffuse water pollution on ecological function while maintaining food security through the implementation of multiple on-farm measures across whole river catchments using local expertise to solve local problems.

  BBC East Inside Out features work from the Wensum DTC

  • 28 January 2019: Sediment Trap Study in the News An interview with Prof Andrew Lovett of the Wemsum DTC and Poul Hoveson of Salle Farm Estates regarding the roadside sediment traps installed on the Estate in 2017 was featured on BBC East's Inside Out programme on 28th January and was followed by features on the national and local BBC websites and has been taken up by the local press. The traps prevent sediment ending up in local watercourse where it smothers the gravel bed and can alter the water chemistry and ecology. The results so far are promising - reducing sediment load into the Blackwater river by over 50%. One trap caught over 7 tonnes of sediment in one year. The programme will be available for 28 days at the following link: - The article on the BBC website is available [here]. Look out for further news in the Eastern Daily Press.
  • 11 December 2018: NFU Farmed Environment Conference The NFU’s first Farmed Environment Conference was opened by NFU President Minette Batters, and addressed by George Eustice MP, Minister of State for Agriculture, Fisheries and Food. The meeting include several case studies by farmers, including one from Poul Hoveson concerning arable farming in East Anglia with discussion focussing on managing the environment alongside producing the nation’s food. A new publication on this theme was launched at the event. To download it and read about Poul’s experiences [ Click here ].
  • 15 November 2017: Workshop - Farming Methods and Machinery - Salle Village Hall: Broadland Catchment Partnership hosted an event which attracted 46 attendees from Norfolk, Suffolk, and Cambridgeshire including 20 farmers (over 7000 ha) along with agronomists, other farm advisers and academics. Presentations from local farmers, agricultural engineers, and academics focussed on traditional and novel cost-effective techniques for improving soil and water and drew on evidence from the Wensum Demonstration Test Catchment, UEA, Harper Adams University, Cranfield University and ADAS trials related to cultivations and cover crops. Lland-Ho’s Earthwake for tramline disruption was on display and attendees were able to walk to a nearby oil seed rape field to discuss soil structure and were taken by tractor and trailer to a field of cover crops to discuss their establishment and destruction. Tramline layout and direction of sprayer travel around the field was also discussed as a simple cost-effective way to improve water resource protection. The event was reported in the EDP and a summary report is also available [click here].
