How do I protect my paddy nursery and field from heavy rain and waterlogging?

When heavy rain is forecast, open and clear your drainage channels in advance so water can leave quickly, because the damage from waterlogging comes from water standing too long, not the rain itself. Once a heavy rain warning is out, prepare the field. Clean and deepen field drains and outlets so excess water drains fast after the rain. Do not apply fertiliser or pesticide just before heavy rain, as it will wash away and waste your money. For a paddy nursery, make sure the seedbed has good drainage and the seedlings are not fully submerged for long, since young plants die if submerged for several days. In flood prone areas, consider submergence tolerant paddy varieties recommended for your region. After the water drains, drain stagnant patches, let the field recover, then resume operations. Keep watching the 7 day forecast during the monsoon so you can drain ahead of each heavy spell. Your KVK can advise on tolerant varieties and recovery steps for your area.
