Challenge Problems
Push your limits with advanced challenges
A researcher needs to calculate AET for wheat, which has a K_c of 1.1 during peak growth. If PET is measured at 75 mm, what is the AET? Discuss how different K_c might alter this result.
💡 Hint: Remember to apply the formula.
If the climate shifts and increases temperature by 5°C, hypothesize how this might impact AET and crop yield. Provide a detailed explanation.
💡 Hint: Consider the effects of heat on both water use and plant health.
