  1. Values in brackets: ±standard deviation between run-off volumes measured in pits and recorded values of run-off. T 0 no SWC measures, no nutrient supply (control plot); T SR stone rows, no nutrient supply; T SRC stone rows + compost; T SRM stone rows + manure; T SRU stone rows + urea; T GS grass strips, no nutrient supply; T GSC grass strips + compost; T GSM grass strips + manure; T GSU grass strips + urea.
