Eight-year-old poplar trees alongside winter oilseed rape at alley-cropping agroforestry

Caption

Eight-year-old poplar trees alongside winter oilseed rape at the alley-cropping agroforestry site in Dornburg, Germany, in November 2022. Wind carries fallen leaves up to 24 metres into the adjacent cropland, where they add carbon and nutrients into the soil as they decompose.
