A Study on Compost Shift in Agriculture of Henan Province, China

Abstract

This paper analyses the potential supply and demand of compost in subordinated prefecture-level cities of 5 comprehensive utilization regions in Henan Province, China. Besides, the author discussed the (potential) demand to supply ratio, and analyse the shift among zones (cities) in response to the change of actual demand rate (actual demand/potential demand) in each comprehensive utilization region in ton·km. Finally, it is concluded that the shifted quantity of compost in ton·km is affected by demand to supply ratio of various prefecture-level cities, and the region with significantly deviated demand to supply ratio between zones has more frequent shift of compost between zones, while that with relatively less deviation tend to keep compost not flowed.
