More water yields more soya
Record yields of soybeans are possible if they are grown on land with a very high water table. The technique known as 'saturate soils culture' has been developed by scientists from the Commonwealth Scientific & Industrial Research Organisation (CSIRO) in Australia. More recently the technique has been introduced into Thailand to fit into the rice paddy system. Land needs to be specially prepared with ridges and furrows and the crop is sown in the normal way on the ridges. After two weeks; water is applied to the field and kept at a level so that the water table is between 5 and 15cm below the top of the ridge. At first the crop tends to go yellow, but it soon recovers. Prom that point on the rate of growth is increased above what would have been attained with a conventional irrigation system. Under the system the plant is never stressed for water, and it is apparent the nodules become far more efficient. Yields of more than eight tonnesperhectarehavebeenachieved under experimental conditions using this technique: under normal conditions It should increase yields by 10% to 25%, which more than compensates for any extra water used.

| Summary: | Record yields of soybeans are possible if they are grown on land with a very high water table.

Under the system the plant is never stressed for water, and it is apparent the nodules become far more efficient.
Yields of more than eight tonnesperhectarehavebeenachieved under experimental conditions using this technique: under normal conditions It should increase yields by 10% to
25%, which more than compensates for any extra water used.
