摘要	PURPOSE:To dry up wet farming land with good draining efficiency at low cost by a method in which the rich soil layer of a wet farming land is removed, a trench is excavated in the water-impermeable layer, excavated soil is mixed with a hardening agent and granulated, and the granules are packed into the trench and embedded with the rich soil layer. CONSTITUTION:The rich soil layer 1 of a paddy field is removed to expose a water-impermeable layer 2, and a trench 4 is excavated in the water-impermeable layer 2. The excavated soil of the trench 4 is put into a granulator, mixed with a hardening agent, and granulated to form granules 5. The granules 5 are put into the trench 4, and the trench 4 is embedded with the rich soil layer 1. Therefore, water in the rich soil layer 1 is separated through the apertures in the spherical granules 5 and drained with good draining efficiency without causing blocking even when used for long periods of time.
