This paper deals with the issue of material cycling in the farm household ecosystem in Jiangxi Province. The results show that N, P and K are accumulating, especially P, in the farmland subsystem. The farmland ecosystem is more stable than the pig gery subsystem. The structure of the system is not rational, and potentially unstable and fragile.
