Evidence & Context
An Upper Detrimental Threshold is identified as prolonged saturation leading to anaerobic conditions, which causes root death, impairs nitrogen fixation, and reduces pasture productivity a significant risk in high-rainfall tropical island environments.
Prolonged soil saturation leading to anaerobic conditions detrimental to pasture health.
This benchmark represents the upper detrimental threshold for soil moisture in tropical island pastures, beyond which prolonged waterlogging causes root death, impairs nitrogen fixation, and reduces pasture productivity.
Based on ecological impacts of anaerobic soil conditions documented in tropical pasture studies.
