Although, Organic-PLUS works mainly with commercial organic farmers and growers, plastic mulch is also a big issue for home gardens and allotments, especially during the COVID-19 pandemic to increase resilience in food supply. A big plastic-mulch citizen science experiment in the UK has just started in April 2020.
Organic-PLUS Associated Partner Garden Organic has done Members’ Experiments ever since the founder Lawrence Hills initiated them 60 years ago, and this year more than 300 gardens and allotments across the UK are taking part. The ‘Alternatives to plastic mulch experiment’ designed by Dr Anton Rosenfeld (Garden Organic, Members’ Experiments Coordinator) uses 50 onion sets and 5 treatments: 1. control – no mulch, 2. woven plastic mulch, 3. biodegradable mulch, 4. paper mulch and 5. own much choice (grass clippings in this case). It is not replicated on one site, but rather on 300 locations where soil and climate conditions are known from the postcodes of the members. Regular data recording (growth, pests, weeds, time input, yields, condition of mulch) will happen during the season.
