                                    It is device to utilize  the collected and prescribed rain water for the purpose of profitable yield of crops in dry lands This technique  is applied to areas which fulfill the water requirements .depending upon  slope of the area with less than 5% soil and cost of earth work

WATER GAS

A mixture of hydrogen and carbon monoxide with small amounts of other gases; made by blowing steam over hot coke or coal

                       

C(s)+ H₂O(g)____ CO(g) + H₂(g)

CH₄ (g) + H₂O(g) ____CO(g) + 3H₂(g)

This production  of water gas using methane is an important step in the preparation of hydrogen for ammonia synthesis . compare producer gas.

The soil with  relatively small pore spaces ( such as clay  or silt soil ) and more quickly waterlogged  than soils with larger spaces such as sand. However, water logging  causes reduction in plant growth because roots can not survive and remain active in the absence of air. Thus, soil saturated with the free water, which may get accumulated on the ground surface.
