0.10 2. The following soil data were obtained for an irrigation experiment with corn, Irrigation of 10 cm was applied on 6/10/88 after monitoring the soil moisture. Depth Bulk Wilting Field Soil moisture content (cm) density point capacity (g/cm) (wg/g) (w, g/g) 6/10/88 6/20/88 0-30 1.2 0.30 0.10 0.20 31-50 1.3 0.12 0.32 0.15 0.25 51-80 1.4 0.14 0.28 0.25 0.20 81-150 1.6 0.15 0.25 0.20 0.15 (a) Calculate depth of penetration of irrigation water, (b) Evaluate evapo transpiration of corn in mm/day, (c) Determine drainable porosity at field capacity assuming p=2.65 g/cm'. (d) If irrigation is withheld as from 6/20/88, how long will it take for corn crop to exhaust the entire water reserves if the ET continues at the rate computed in 'b' above? 0.10 2.
