Challenge Problems

Push your limits with challenges.

Question 1

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.

Question 2

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.
