| Research Abstract |
Livestock farmers in Japan have been trying to increase the number of livestock on a farm in order to retrench production costs through the effects of economic scale benefits. As a result, they face a pile of barnyard manure that they can not dispose of.
On the other hand, field-husbandry farmhouses need organic fertilizer to produce good quality products. The problem associated with barnyard manure disposition seems capable of being solved if field-husbandry farmhouses could use manure compost for their production. Even so, the manure compost recycled-use system between livestock farmers and field-husbandry farmhouses does not work well.
To solve this kind of problem, we need to establish some policies promoting recycled use of manure compost. The purpose of this research is to evaluate policies promoting recycled use of manure compost from an economic surplus standpoint. The results are, (1) We should not supply manure disposition services to a livestock farmer free of charge, (2) A policy to subsidize the fixed cost of manure compost-producing facilities is economically better than a deficiency payment price policy for manure compost, (3) Establishing a nation-wide compost trading system is more beneficial to the society than keeping up only local compost trading systems.
