What lies beneath? Improving potato yield forecasting and crop management

What lies beneath? Improving potato yield forecasting and crop management

As part of UK Research & Innovation’s (UKRI) Transforming Food Production (TFP) challenge, Lincoln-based B-hive Innovations Ltd and Shropshire’s Harper Adams University have been awarded £391,000 for the development of their Tuberscan project, which aims to use ground-penetrating radar to improve the level of crop knowledge and management of potato crops before they are harvested.

B-hive’s director Vidyanath (Vee) Gururajan explains that the company, which was created by the shareholders of leading fresh potato supplier Branston as a stand-alone agri-tech business, had undertaken its own small-scale proof of concept testing and applied for the TFP to progress from this initial stage to having a working prototype which can be developed and used to demonstrate the feasibility of the technology.

“The funding application process enabled us to think through how we are going to deliver Tuberscan, when we are going to deliver it, what will it cost us to delivery it, and also how to decrease and mitigate the risks,” says Vee. “The funding means that we are now able to go from proof-of-concept to a working prototype in 18 months, which will be the mark of success for us. The funding also means that we have been able to employ the right skills and also work with the right partners, such as Harper Adams and Branston – factors that are critical to the success of this project.”

From UKRI’s perspective, Tuberscan also provides an illustration of how traditional industries such as farming adopt new technologies and data-driven approaches, while helping to increase agricultural productivity and meet the industry’s climate change ambitions of having zero net greenhouse gas emissions by 2040.

“Tuberscan is a good example of a technology that could be, and is being, used to increase yield and productivity, and hopefully therefore reduce emissions,” explains Katrina Hayter, the ISCF Challenge Director for Transforming Food Production at UKRI. “They are using a lot of technology here: sensor technology as well as using data and machine learning which predicts when to harvest the crop at the optimum time.”

Katrina stresses that the TFP Challenge is not only interested in the technology itself, but in how it can be utilised across the whole supply chain: “It’s only really when you put these technologies together that you get real industry transformation, she adds. “It is really inspiring to see this project in the context of the other projects that B-hive Innovations are involved in, and how that technology is being used in a large supply chain with Branston and their customers; and how it can reduce emissions, boost productivity and decrease waste.”

Having a route for the industry adoption of the technologies that have been supported is as important as the technologies themselves. “Because B-hive is working with Branston, who supply Tesco and Waitrose, this innovation can be adopted at scale by their grower network, which is really important,” says Katrina. “It’s not about creating technology that just sits there – it’s actually solving a real-world problem, such as out-of-specification potatoes which are a huge source of waste. Tuberscan is helping the industry deal with this problem and reduce its environmental impact while also boosting productivity.”
