This data file has information on the daily soil water content of different crops based on TDR measurements. First row indicates header Columns A: refer to treatment or crops G1 indicates maize G5 indicates switchgrass G6 indicates miscanthus G7 indicates grass mixture G8 indicates hybrid poplar G10 indicates native prairie Column B:soil depths (probes measuring soil water content at 10 cm, 20 cm, 35 cm, 50 cm, 65 cm, 90 cm and 125 cm) Column C: date of measurements Column D: daily values of volumetric soil water content (v/v) Additional notes: This data file is used for the following figures -the daily soil water content as in Fig 1b, -to calculate ESWD, DUL, LL and PESW as in Fig 1c -to calculate the cumulative values of SWD, ET as in Fig 1d -to calculate water use of each cropping systems as in Fig 2a. Refer separate data table (Data table for Fig 1 b,c,d & Fig 2a_ step-wise procedure to estimate ET from daily soil water content)and associated readme files, for the step-wise procedure that calculates daily water use from volumetric soil water content.
