Abandoned homestead reclaimed soil has poor structural structure and lack of nutrients. In this study, organic fertilizer (F), curing agent (S) and fly ash (C) were used as amelioration materials to improve nutrient content of abandoned residential land reclamation soil. After 3 years of wheat-corn rotation, soil samples were collected to determine soil organic matter, total nitrogen, available phosphorus and available potassium contents. The results showed that soil organic matter content at the depth of 0-30 cm soil layer in the treatments of F increased significantly due to organic fertilizer input. The content of total nitrogen, available phosphorus and available potassium in the treated soil with improved materials increased significantly compared with the control. It indicated that the addition of amelioration materials and continuous tillage had significant effect on improving soil fertility in the abandoned homestead reclaimed soil.
