The economic impact of living mulch in European crop rotations

This technical-economic study evaluates the integration of living mulch in European crop rotations from 2011 to 2013, focusing on working time, fertilisation, income, expenses, and net margins. Based on trials across six crops in France, results show variable net margins depending on yield impacts and management costs. Positive outcomes occurred when living mulch was sown with rapeseed, while high seed costs and poor establishment at La Jalillière led to negative margins. Site-specific factors such as seed costs, crop compatibility, and weed control efficiency significantly influenced profitability. The approach requires no special equipment, ensures year-round benefits, and is applicable across Europe. Data from Bougainville, Dosson, La Jalillière, B. Destouches, and GACE St Amel are summarised in Table 1.
