Soil properties of cultivation sites for mountain-cultivated ginseng at local level

다국어 초록 (Multilingual Abstract)

Background: Identifying suitable site for growing mountain-cultivated ginseng is a concern for ginsengproducers. This study was conducted to evaluate the soil properties of cultivation sites for mountaincultivatedginseng in Hamyang-gun, which is one of the most well-known areas for mountain-cultivatedginseng in Korea.
Methods: The sampling plots from 30 sites were randomly selected on or near the center of the ginsenggrowing sites in July and August 2009. Soil samples for the soil properties analysis were collected fromthe top 20 cm at five randomly selected points.
Results: Mountain-cultivated ginseng was grown in soils that varied greatly in soil properties onconiferous, mixed, and deciduous broad-leaved stand sites of elevations between > 200mand < 1,000 m.
The soil bulk density was higher in Pinus densiflora than in Larix leptolepis stand sites and higher in the< 700-m sites than in > 700-m sites. Soil pH was unaffected by the type of stand sites (pH 4.35e4.55),whereas the high-elevation sites of > 700mwere strongly acidified, with pH 4.19. The organic carbon andtotal nitrogen content were lower in the P. densiflora stand sites than in the deciduous broad-leaved standsites. Available phosphorus was low in all of the stand sites. The exchangeable cationwas generally higherin the mixed and low-elevation sites than in the P. densiflora and high-elevation sites, respectively.
Conclusion: These results indicate that mountain-cultivated ginseng in Korea is able to grow in veryacidic, nutrient-depleted forest soils.
