The new “Potato‑LITE” project aims to deliver novel, sustainable cultivation approaches to minimise tillage intensity throughout the UK
Who We Are
The consortium is comprised of PepsiCo, McCain Foods, GRIMME UK, forward thinking potato farmers and leading research organisations (Harper Adams University, Cranfield University and CHAP) with input from expert consultants. It receives funding from Innovate UK to pilot new approaches to tillage which directly benefit farming communities while lowering carbon emissions.

Defra and UKRI, as part of the Farming Innovation Programme, recently announced funding for Potato‑LITE – a multi-million pound project over four years, that will develop novel machinery and cultivation practices for UK-based potato farms to optimise tillage intensity, improve soil health and lower greenhouse gas (GHG) emissions.
This project will be delivered by a cross-industry consortium led by PepsiCo in partnership with McCain Foods GB Ltd, GRIMME UK Ltd, Crop Health and Protection (CHAP), Cranfield University, Harper Adams University; and farmers from Strawson Limited, JRO Griffiths Ltd, JM Bubb & Son and H Sutton & Son.
Tillage is considered one of the largest drivers of GHG emissions after fertiliser use, making this a critical area for improvement. Current potato tillage operations can lead to loss of soil organic carbon into the atmosphere as carbon dioxide (CO2). Global research has shown that the loss of soil carbon can reduce soil health, increase the need for fertiliser inputs and reduce farm profits – making the investment in low intensity tillage solutions more important than ever.

Dr. Mac McWilliam, R&D Director of Agricultural Science at PepsiCo
“Agriculture is at the heart of PepsiCo, including our Walkers brand in the UK. As a business, we’re deeply committed to developing scientifically validated solutions which will enable us to make progress towards our global PepsiCo Positive (pep+) goal of spreading regenerative farming practices across 7 million acres by 2030.
The Potato-LITE project will help us drive this positive action by transforming potato cultivation and improving soil health whilst reducing greenhouse gas emissions. We are delighted to be working in partnership across the supply chain, including our growers, as we work towards a net zero future.”

Dr. Alex McCormack, Innovation Technical Lead at CHAP
“Working alongside our public-sector partners and leading experts from Harper Adams University and Cranfield University, will enable us to better understand the impact of intensive cultivation operations seen in potato and root crops. This project aims to mitigate the negative effects on soil health, reduce GHG emissions linked to production and enable the sector to transition towards regenerative practices.”
Potato-LITE began in Spring 2023, where experimental commercial-scale low intensity tillage approaches were trialled by partner UK growers, with performance and commercial viability to be validated by the consortium following harvest. These efforts will help uncover new low intensity tillage solutions for the potato farming industry whilst quantifying the effects on soil health and GHG emissions against current best practice methods.

Ed Hodson, Potato Product Specialist at GRIMME UK
“We are very excited to start the Potato-LITE project which is vital to help set the direction of potato production techniques for the near future.
Innovative equipment and processes are needed to move forwards as UK production has reached a plateau. This project will bring new solutions to deliver commercial and environmental benefits through reducing the intensity of cultivations.
Growers will also be provided with the tools to make informed field by field decisions to identify the best process of growing potatoes, resulting in environmental benefits but also cost savings, labour reductions and improved work rates.”
As Potato-LITE kicks off in Shropshire, the consortium looks forward to making progress against its shared goal of developing an improved potato sector across Britain through validating the financial and climate benefits of embracing low intensity tillage solutions.

Mark Strawson, Managing Director at Strawson Limited
“We are working hard on implementing regenerative farming practices to improve soil health. Currently, potato cultivation is a heavy process, with significant volumes of soil being moved to bury stones and clods to establish a friable seed bed.
Climate change disruptions and the need to reduce energy use have brought this work into sharp focus. As such, innovative solutions are required to directly tackle such challenges whilst also reducing fuel use and labour costs linked to establishing a potato crop.
We are excited to work with Innovate UK, other growers, academic partners, consultants and the supply chains to develop novel processes and use modernised, lower impact cultivation machinery to establish sustainable potato crops in the UK.”

James Young, Vice President of Agriculture at McCain GB & Ireland
“Given the increasingly unpredictable climate, the shift towards smart and sustainable farming practices is vital to futureproof the farming industry.
At McCain, we are committed to implementing regenerative agriculture practices across 100% of our potato acreage by 2030. To achieve this goal, we’ve created a Regenerative Agriculture Framework, with minimising soil disturbance as one of its core principles. We are thrilled to work alongside industry leaders and several of our growers on Potato-LITE to explore optimised systems for potato cultivation to ensure the long-term viability of potato growing in the UK.”

McCain Foods is the UK’s largest manufacturer of frozen potato products, employing over 1,300 people across five processing facilities and a dedicated seed potato business. We are the largest purchaser of the British potato crop, buying around 15% of the total market from 250 growers, some of whom have worked with us for three generations.
McCain is committed to implementing regenerative agriculture practices across 100% of our global potato acreage by 2030. To support our growers in their progression towards a more regenerative model, we have developed a Regenerative Agriculture Framework to set a minimum credible standard for the industry. This was developed in consultation with a range of stakeholders including academia, scientific organizations, farmer representatives, public institutions, customers and NGOs.

GRIMME was founded in 1861 as a forge in Damme (Germany) and today, the family-owned company employs more than 2850 people worldwide.
