Root sampling in August in the grassland experiment. It is illustrated with a perennial ryegrass-red clover mixture including plantain and caraway. Dashed horizontal lines represent crop rows and symbols refer to sampling points for the different plant species (n = 2 for each species and for between-row samples). For red clover, caraway and plantain, each soil core (0–50 cm) for root sampling was taken on an individual plant.
