| ABSTRACT |
| This research was carried out to evaluate the effect of the reclamation procedure with respect to soil fertility and nutrient distribution pattern in the reprecipitated reclaimed soil. Although there was an obvious indication of low levels of essential nutrients in the reclaimed farm lands (organic matter = 0.32 g kg-1, total N = 380.8 m g kg-1, available P = 4.7 m g kg-1 ), compared to the undisturbed farm lands (organic matter = 2.5 g kg-1, total N= 1 220 g kg-1, available P = 20.8 mg kg-1), the uneven pattern of nutrient distribution was also shown to have been the major limitation to successful reclamation. Further improvement can be achieved through the integration of intensive eco-farming systems using proper fertilizer field correction (PF-FC) and organic manure for successful reestablishment and management of newly reclaimed farm lands overlying the Xuzhou coal mine subsidence. |
