The following chart shows measurements of soil water content and soil water potential over an entire growing season from sensors installed at two depths under an area of turfgrass on BYU campus. During the season, three different irrigation schedules were evaluated, each labeled as A, B, or C. From your evaluation of the data in the chart, give a response to the following questions: What is the approximate soil water content when this soil is near field capacity? What is the approximate soil water content when this soil is near the wilting coefficient? Which of the irrigation schedules do you think is best and why? A: Daily irrigation according to a fixed start time B: Irrigation only scheduled according to observed water potential at the 6 cm depth C: Irrigation limited to once per week
