Rice was cultivated using four water-saving methods.
- class="label">•
Methods were flooded, alternating wetting and drying (AWD), or furrow-irrigated (FI).
- class="label">•
Rice methylmercury was low in AWD fields and lowest in FI fields.
- class="label">•
Soil microbiotas differed between flood/AWD fields and FI fields.
- class="label">•
Microbial genera known to contain mercury methylators were lowest in FI fields.
