Soil organic matter (SOM) is an important indicator to assess soil fertility, health and quality. For proper managements of agricultural fields, a long-term monitoring of changes in SOM contents in field and estimation of national accumulation of SOM are required. In this study, SOM and agricultural field area of paddy and upland systems were investigated from 2013 to 2020 for all administrative provinces of South Korea. Total agricultural field area was decreased by 4.8% and 9.0% in 2016 and 2020 compared with 2013, respectively. In paddy field, SOM concentration was 23.5g kg<SUP>-1</SUP> in 2013, which was gradually increased by 2.2% in 2020. Despite that SOM concentration increased at a field scale, national SOM accumu ... 전체 초록 보기
