Challenge Problems

Push your limits with challenges.

Question 1

A farmer needs to determine the water allocation for their multi-crop farm, where a corn crop requires a NIR of 600 mm, soybeans at 400 mm, and wheat at 200 mm. If the efficiency rates for irrigation systems differ (80% for corn, 70% for soybeans, and 60% for wheat), calculate the GIR for each crop, discussing how varying crop requirements impact total water use.

💡 Hint: Focus on the efficiency rates for accurate calculations.

Question 2

Analyze how improving irrigation efficiency from 60% to 80% affects GIR for a crop with a NIR of 500 mm. Discuss the broader implications for water resource management.

💡 Hint: Consider the difference efficiency makes in water rationing.
