This study was conducted to establish the techniques of the continuous wheat production of high yield level and to standardize of quality uniformity. It was selected the experimental places which were Iksan of Jeonbuk, Gwangju metropolitan city and Hapcheon of Gyeongnam. Farmers of participating in the experiment were 13 persons with two types of advanced and lower levels of their techniques in wheat cultivation, and total numbers of fields were 22 fields. The common information on the field soils were silt loam and loam in soil textures, all most deep and some moderate in soil depth, imperfectly drained in drainage classes, coastal and interior plain with some alluvial fan or local valley in land topography. It was investigated in status of the physico-chemical properties of soils. Soil pH was 6.0 in mean values with 5.2 ~ 7.5 ranges, organic matter(OM) was 25 g/kg with 16 ~ 39 ranges, available P2O5 194mg/kg with 47 ~ 586 ranges, available SiO2 164mg/kg with 57 ~ 454 ranges, in exchangeable cations, K was 0.46 with 0.20 ~ 0.98, Ca was 6.2 with 3.6 ~ 11.7, Mg was 1.8 with 0.9 ~ 3.4 cmol(c)/kg in ranges, and these properties of soils were higher in advanced than those of lower level farmers. The amounts of fertilization in N-P2O5-K2O were 184-49-50 kg/ha in farmers application, 108-114-47 kg/ha in soil testing and 94-83-41kg/ha in standard recommendation. Fertilizer application amounts by farmers were higher than those of soil testing and standard recommendation by 76 ~ 90 kg/ha in N and 3 ~ 9 kg/ha in K2O, and less by 34 ~ 74 kg/ha in phosphate fertilizer.
