In order to obtain useful information for environment-friendly management of upland soils, the chemical characteristics of 170 upland fields in Gangwon province have been monitored every 4 years since 2001. In 2017, the pH, electrical conductivity (EC), organic matter (OM), and available phosphate (Avail. P₂O₅) of the soil samples were 6.4, 0.89 dS m-1, 32 g ㎏-1, and 742 ㎎㎏-1, respectively. The values of exchangeable (Exch.) potassium (K), calcium (Ca) and magnesium (Mg) were 1.18, 7.6, and 2.0 c㏖c ㎏-1, respectively. In terms of the long-term change, the contents of EC, OM, and Exch. cations in upland soils showed increasing tendency. However, significant changes in the contents of pH and Avail. P₂O₅ were not observed since 2013. The ratio of optimal range of pH and OM in upland fields reduced from 55% in 2001 to 36% in 2017 and from 33% to 27%, respectively. The ratio of excessive range of Exch. cations have increased. Therefore, it is necessary to apply the lime and fertilizers based on the soil test in order to properly manage the soil fertility of the upland soils. Meanwhile, average contents of Cd, Cu, Ni, Pb, Zn, and As were 0.23, 21.0, 13.5, 11.0, 82.6, and 4.8 ㎎㎏-1, respectively. The results from the study imply that environment-friendly soil managements including the cultivation of green manure crop and application of organic composts are necessary to improve the soil chemical properties of upland fields.
