Challenge Problems

Push your limits with challenges.

Question 1

A farmer analyzes their crop and finds that through season rainfall they receive an average of 150mm of effective rainfall, but their crop needs 350mm for optimal growth. Calculate the irrigation requirement and discuss alternative strategies if IR exceeds 200mm.

💡 Hint: Focus on the difference between WR and ER and think creatively about solutions.

Question 2

Assume the water requirement for a newly planted orchard is calculated at 500mm; if only 200mm of effective rainfall is anticipated, suggest how the farmer can optimize water resources while keeping the irrigation requirement within sustainable limits.

💡 Hint: Think of methods to use water efficiently and sustainably.
