A Relationship between the δ13C values of slurry and the annual dietary proportion of maize (DM). B Relationship of the δ13C values in cattle slurry (annual mean) and the area cultivated with maize [as a proportion of the total agricultural area per farm]. Each point refers to one farm (A–Q) and symbols indicate soil landscapes. R2 shows coefficients of determination and grey bands show 95% confidence interval
