Challenge Problems
Push your limits with advanced challenges
A commercial farm has apple trees with a root zone depth of 800 mm, an allowable depletion of 30%, and a daily ET_c of 8 mm. Calculate the irrigation frequency and discuss how altering any of these values might affect scheduling.
💡 Hint: Utilize the irrigation frequency formula while considering the implications of each factor.
Assume that due to drought conditions, the ET_c increases to 12 mm/day for the same conditions as before. Calculate the new irrigation frequency and analyze the impact of environmental factors on irrigation scheduling.
💡 Hint: Adjust the ET_c in the formula to see the impacts of increased water loss.
