This study was carried out to investigate the improvement of soil physical and chemistry in black raspberry sequential field. We had used the subsoil-crusher, oriental herbal, perlite, popped rice hull, burned charcoal of rice hull and peat moss as a soil conditioner. On the whole, the physical and chemistry properties of treated-plots was higher than those of Control field after applying soil conditioners. Before planting, the pH and E.C. range of field was 4.9~5 and 0.5~0.6 ds/m, respectively. After applying soil conditioners, the pH and E.C range of Control field was altered to 4.3 and 2.2ds/m and the pH and E.C range of peat moss-field was 5.2 and 1.3 ds/m. The significant difference(p<0.05) in pH and E.C value was observed between Control-field and peat moss-field. In the size of soil aggregate structure, the aggregate structure weight of Control over 4mm long was 44 g and treatments of perlite, popped rice hull, burned charcoal of rice hull and peat moss was 53 g, 65g, 65g and 72g, respectively. There is a significant difference(p<0.05, 0.001) between Control and treatments. In the results of chlorophyll analysis, all of the treated-plots except for the oriental herbal have a high chlorophyll value (p<0.05, 0.001) compared to the Control. In view of the results so far achieved, there is a great difference on the frequency of dead plant between Control and treatments. The dead plants number of Control, subsoil-crusher, oriental herbal, perlite, popped rice hull, burned charcoal of rice hull and peat moss was 31, 21, 7, 12, 10, 12 and 2, respectively.
