A potato merchant has created a mobile app that allows retailers and processors - and potentially consumers - to access crop traceability data.

Phillip Kemp, founder of Mercian, had initially developed the app to make “our life easier” when planning deliveries. It had evolved into a “comprehensive potato traceability scheme,” said Kemp, allowing buyers to access a range of information including variety, weight, date of planting, spraying schedule and CO2 emissions.
