Which consequence results when rainfall exceeds drainage capacity on steeply terraced Andean farmland?

💡 Explanation

When rainfall exceeds drainage capacity, topsoil leaching occurs because water flows rapidly along the terrace, removing nutrients like nitrogen essential for plant growth. Therefore nitrogen depletion occurs, rather than carbon sequestration, phosphorus uptake, or reduced methyl which require different soil/microbial conditions.
