On 26th September, researchers working on Organic-PLUS at Coventry University’s Centre for Agroecology, Water and Resilience held an open day for farmers and other stakeholders on the topic of plastic film mulches. The event was part of Innovative Farmers, a Soil Association scheme which brings farmers and researchers together to devise on-farm ‘field-lab’ trials.
There were several short presentations on topics including the overall use of plastics in agriculture/horticulture and Organic-PLUS’s 2019 field trials – Francis Rayns and Judith Conroy have been working alongside 5 Acre Community Farm, trialing a number of mulch films including: two fossil fuel derived plastics, two biodegradable films currently available to growers and two novel materials developed by project partner the Częstochowa University of Technology. As well as measuring the effectiveness of the mulches and subsequent yield, soil samples are being analysed to find out whether substances such as phthalates have leached from the mulches.
The day concluded with a tour of 5 Acre Community Farm to see the Organic-PLUS onion and cabbage trial plots, and to find out more about 5 Acre’s experiences of using biodegradable mulch films over the past few years. There will be a further Innovative Farmers meeting in the next few weeks which it is hoped will lead to on-farm trials in 2020.
