Which limit impacts crop yield when Incan terrace farming encounters increased rainfall?

A)Nutrient leaching from upper terraces
B)Increased root rot from waterlogging
C)Decreased sunlight exposure to crops
D)Higher thermal inertia delays germination

💡 Explanation

Increased rainfall causes excessive downward water flow over the terraced soil, triggering nutrient leaching because topsoil minerals are carried away from the upper terraces. Therefore, crops on higher terraces suffer, rather than root rot which is more problematic for lowland agriculture.
