The Sustainable Landscapes Humber Project involves these farmers growing cover crops in the window between harvesting peas and sowing their next food crop. The project could also reduce flooding and improve soil health.
The project is a collaboration between Yorkshire Water, Birds Eye, and supply chain consultancy Future Food Solutions, with other brands joining in as different commodities are grown in rotation. Research expertise is being provided by the University of Hull, with support from Teesside University.
The cover crops – christened pop up rainforests by Future Food Solutions – are made up of a diverse range of plant species chosen for their ability to capture CO2 from the atmosphere.
Trials funded by Yorkshire Water and facilitated by the UK Birds Eye Agricultural Team show that growing cover crops can increase soil organic matter by up to 40 tonnes per hectare, which can sequester nett over four tonnes of atmospheric carbon per year.
As soil organic matter has fallen by 50% over the past 60 years, using cover crops to restore these levels not only has the potential to re-establish soil health, but could also help to reverse the ongoing rise in atmospheric CO2 levels.
The pre-project trials have already achieved a rise in soil organic matter, more than doubling levels in just five years, from 3.0 % to over 6.0 %.
Andrew Walker, Asset Strategy Manager for Yorkshire Water, said the Sustainable Landscapes Humber Project laid the foundations for addressing some of the most urgent problems the world is currently facing. "Growing cover crops to increase soil organic matter is one of the most effective way of combatting the major environmental issues we face today.
"In just seven weeks, they generate enough carbon-sequestering organic material to make a significant dent in atmospheric CO2. If grown on a global scale, arable farming could become the first sector of the economy to be net carbon zero."
He added that the Sustainable Landscapes Humber Project could also play a major role in the reduction of flooding in Hull – a notorious problem for the city as much of it lies below the high-tide line.
Yorkshire Water is a core partner in the Living With Water partnership in the city, alongside East Riding of Yorkshire Council, Hull City Council and the Environment Agency.
Andrew Walker continued: "Research shows that achieving just a 1% increase in soil organic matter would enable agricultural land to store an extra 200,000 litres of water per hectare.
"Therefore, this project has huge implications for flood attenuation in and around Hull. Birds Eye has long term relationships and collaborations with its growers, so by working with them to increase the levels of soil organic matter in the Humber region, we can make a real impact."
Paul Rhodes, director of Future Food Solutions, added that growing cover crops also has significant implications for soil health and the wider environment. He said: "The plants' root structure holds the topsoil in place reducing erosion, and the increase in organic matter means less farm inputs are required, enabling farmers to grow food more efficiently and profitably.
"Of the inputs that are required, less are leached away into the waterways, making for healthier rivers and watercourses and this has a positive knock on effect on local flora and fauna."
Fellow Future Food Solutions director, Steve Cann, described launching the Sustainable Landscapes Humber Project as a great example of collaboration between utility partners, the supply chain and farmers, and this was just the start with the initiative set to grow as new crops are drilled.
He said: "Because of the unique nature of the Birds Eye supply chain and interactions with the growers of the Green Pea company, peas can be the catalyst for change; the same farmers will grow wheat, barley and oil seed rape for other supply chain partners so the potential to upscale the project is huge.
"As further crops come into play, we expect to see more food brands coming on board and more farmers starting to grow cover crops as the benefits become clear. This hugely exciting project is set to grow and grow."
