Problem 11.6: The following crops will be cultivated with the indicated areal percentages; cotton (30%), corn (30%), and wheat (40%). The area lies at 36°N latitude. No precipitation is observed in July. Maximum groundwater table elevation is 1.2 m below the ground surface after each irrigation. The minimum readily available moisture in the root zone is estimated to be 60 mm. Taking D-9 m and t-28°C, determine the value of L. Assume that wheat has the same crop coefficient as corn. Take K=1 m/day, μ-0.10, d-2 m, h-0.4 m, ro-0.1 m. Answer: L-66 m
