Status and Changes in Chemical Properties of Orchard Soils in Gangwon State

Abstract

The chemical properties of orchard soils in Gangwon state have been monitored every 4 years from 2002 to 2022 in order to provide basic information for orchard soil fertility management. In 2022, the soil chemical properties of orchard were 6.3 of pH, 0.82 dS m -1 of EC, 38 g kg -1 of organic matter (OM) and 803 mg kg -1 of available phosphate (Avail. P 2 O 5 ). Exchangeable (Exch.) potassium (K), calcium (Ca) and magnesium (Mg) were 1.2, 7.2 and 2.0 cmol c kg -1 , respectively. The distribution percentages within optimal range of pH were
