Heavy black (vertisol) soils swell and drain slowly, so standing water after heavy rain quickly suffocates soybean roots and triggers yellowing and root rot. The first priority is fast surface drainage: open field drains and channels to lead water off, and avoid traffic on the wet soil. Planting soybean on a broad bed and furrow or ridge and furrow system from the start lets excess water run off in the furrows and is a proven practice for vertisols in central India. After water recedes, a light foliar spray of a balanced grade or urea can help the crop recover from temporary nutrient loss, and watch for root and stem diseases. Long term, raised bed planting and good organic matter improve drainage. Confirm practices with your KVK and adjust nutrition to your soil test; do not over apply.

The broad bed and furrow system saved my soybean in a wet year. The water ran off in the furrows while the beds stayed workable, and the crop did not drown like my flat planted neighbour's. Setting it up at sowing is the key, you cannot do much once the rain has already flooded a flat field.

Keep your field drains and outlets cleared before the monsoon, not after the water is already standing. My drain was choked with weeds when the big rain came and the water just sat and rotted the roots. Now I clear the channels ahead of the season so the water has a quick way out.

After the water drained my crop was pale and shocked, and a light foliar spray of a balanced soluble grade helped it pick back up while the roots recovered. Also keep an eye out for root and stem rot in the days after, because the waterlogged plants are weak and disease moves in fast.

Clear your field drains and outlets before the monsoon, not after the water is standing. My choked drain let the rain just sit and rot the roots one year. Now I clear the channels ahead of the season so water has a quick way out.
