Which outcome arises due to reduced soil porosity in terraced maize farming impacted by prolonged rainfall?

💡 Explanation

When soil porosity reduces from prolonged rainfall, waterlogging occurs because soil pores collapse restricting oxygen diffusion, causing roots to experience anaerobic conditions that produce toxic metabolites. Therefore anaerobic root damage results,rather than potassium uptake, nitrogen fixation, or blight resistance, which thrive in well-drained, aerated soil and dry foliage.
