Cropping System Effects on Soil Properties and Tuber Quality of Potato: Continuous Cropping Vs. Rotation with Napa Cabbage and Soybean

다국어 초록 (Multilingual Abstract)

The importance of soil quality has been emphasized to improve crop productivity and quality. Many factors not only chemical, physical, and biological properties but also managements affect soil quality. The use of a cropping system could influence soil and crop qualities. In this study, two cropping systems-continuous and rotation with napa cabbage (Brassica campestris var. Pekinensis) and soybean (Glycine max L.) were compared on soil characteristics and potato (Solanum tuberosum L.) productivities. Chemical, physical, and biological properties were analyzed considering soil characteristics while potato yield and tuber nutrition were investigated to evaluate potato productivity and quality. Total yield was higher in the rotation despite lower input. There was no significance with soil chemical properties and porosity. Soil hardness data were higher value i n rotation to the 25 ㎝ depth but the tendency was reversed to the 45 ㎝ depth. Soil microorganism activities showed a higher value on rotation during potato cultivation. Phosphate was higher in rotation while magnesium and potassium were higher in continuous inside potato tuber.
