Cover crop funding scheme to reduce nitrate levels in groundwater extended
We are working with Affinity Water and farmers to expand the EnTrade scheme and encourage the use of cover crops to reduce nitrate levels in water.
We have again teamed up with The Farming and Wildlife Advisory Group East and Affinity Water, in and South Cambridgeshire and North Hertfordshire, to cover the cost of growing cover crops. Building on the success of the 2019 cover crop scheme we are now extending the pilot into the 2020/21 growing season, targeted at reducing nitrate leaching from agricultural land.
Using the EnTrade platform and a reverse auction the scheme aims to target a wider area and the nitrogen-saving target has been doubled to 40 tonnes.
The EnTrade platform allows farmers to say what price they are willing to be paid to grow an area of cover crop, allowing them (instead of the water companies) to determine the price per hectare and the resulting nitrogen saving. However, as this is an auction, successful bids have to be competitively priced to ensure the water companies pay the best price for the ecosystem service provided.
"Cover crops provide a range of benefits to the farmer and the wider environment, including reducing nitrate leaching and soil erosion. However, the cost of seed and establishment of the crop can put some farmers off, so this scheme allows the water companies to obtain the benefits they provide but we share the financial cost. We know that in several Hertfordshire and Cambridgeshire groundwater catchments we are seeing increasing nitrate concentrations, and cover crops can help mitigate this as well as providing other benefits to the soil and the environment. Nitrate concentrations are also rising in South Cambs.
Bids that include species that are more effective in reducing nitrate leaching and have earlier establishment dates will capture more nitrate therefore are likely to be more competitive. The bidding system includes a dial which will indicate to farmers where their bid sits in comparison to other bids."
Shaun Dowman, Agricultural Advisor, Affinity Water.
By placing a bid on EnTrade farmers will receive immediate feedback on the nitrate saving of their cropping choices and their standing in the auction.
“If a bid becomes uncompetitive, the farmer will receive an email informing them of this. It is a very fair bidding system, as it allows farmers to adjust and edit their bid at any time before the auction closes.”
“Whether farmers are new to the scheme or have taken part previously there is full support available to them to help them make the right cover cropping choices for their farms. FWAG East will be supplying advice on cover crops and will help farmers through the bidding process.”
Jennifer Thomas Catchment Advisor, Cambridge Water.
Crops which bids can be placed for include:
- Oil Radish
- Turnip Rape
- Forage Rye
The farmer can also include other species of their choice up to a maximum of 25% of the eventual cover.
