Explanation
In flooded or submerged soils common to rice fields, oxygen availability is limited, creating anaerobic conditions. Under these circumstances, ammonium (NH4+) remains more stable and accessible to rice plants compared to nitrate (NO3-) and nitrite (NO2-), which tend to be less stable and can be lost through denitrification. Therefore, ammonium is the preferred nitrogen form for rice grown in submerged soils.
