How can waterlogging affect crops?
Answer and explanation
Correct answer: Roots may get less air and plants may weaken
During waterlogging, soil pores fill with water and less oxygen reaches the roots. Root respiration and nutrient uptake are affected, so plants may weaken and yield may fall. Waterlogging does not always increase nutrient availability; nutrients may also be lost under such conditions. Exam tip: link waterlogging mainly with lack of oxygen around roots.
