It is known that it is appropriate to maintain non-cultivated or abandoned paddy fields in suitable condition for timing their restoration, as part of a farmland resources management system preparing for the possibility of a food supply shortage in the future. Although it is required to repeat weeding and repairs every year in order to maintain the integrity of fallow paddy fields at a low price, examination of the concrete contents of the method has not been sufficient. So, in this research, we conducted such research for the purpose of proposing a suitable method ofeffective maintenance of a fallow paddy field. As a result, we show that weeding of today's fallow paddy fields is lacking summer fallow cultivation and is dependent on chemical herbicides. Moreover, we demonstrate two points. The first is the importance of inundation management, which not only reduces the need for chemical herbicides but also is a labor saving measure when we focus on restoration of abandoned paddy fields. The second point is the spread of summer fallow cultivation will become a solution for decreasing the use of chemical herbicides. M oreover, we proposed about the spread conditions of summer fallow cultivation.
