In December of 2020, the BBC, in partnership with the Royal Society, created an informational video titled “Why soil is one of the most amazing things on Earth.” (You should search for and watch it sometime.) The video features multiple sections that highlight facts about soil that demonstrate its importance and value. Very briefly state and describe two things or facts you would include in such a video if you were helping to create it.

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
