Suppose you were hired to design an automatic irrigating system for a wealthy homeowner’s garden. You determine that the flower beds should be kept at a water potential above –60 kPa but not wetter than –10 kPa, as the annual flowers here are sensitive to both drought and lack of good aeration. The rough turf areas, however, can do well if the soil dries to as low as –300 kPa. Your budget allows either tensiometers or electrical resistance blocks to be hooked up to electronic switching valves. Which instruments would you use and where? Explain
