Revitalizing Mountain Ginseng Cultivation in North Jeolla Province,South Korea

A study was made of measures to revitalize mountain ginseng cultivation in the eastern mountainous area of Muju, Jinan and Jangsu municipalities of North Jeolla province, South Korea. The targeted area is typical forested land and is utilized for the cultivation of ginseng. Access to seeds and seedlings for mountain ginseng cultivation is relatively easy in North Jeolla province, and the species is cultivated widely (on 63 % of the area of the province and by 74 % of farmers). This study investigated the current state of mountain ginseng cultivation and business management, including production costs and subsidy, sales and distribution system, and other business management concerns. A survey was conducted on 86 mountain ginseng-cultivating farming households living in the targeted area in 2013. It is concluded that to achieve greater production an aggressive government policy promoting the renting out of suitable sites for mountain ginseng cultivation in national and public production forestland to individual farms and farming cooperatives is necessary. Further research on increasing the survival rate of cultivated mountain ginseng (CMG) until harvesting and preventing damage by wild animals is also deemed necessary. More effective use of related municipal budget subsidy needs to be supported selectively to the enterprising farmers who aggressively pursue mountain ginseng cultivation and business management. Opening CMG retail stores to realize sustainable income growth and developing various processed products will increase farm income. The government needs to introduce policies to sustain consumer trust in CMG through initiatives such as establishing a CMG quality management system for growers, distributing government-approved seeds, and implementing a government-based CMG purchase system.     

Understanding the Relationships Between American Ginseng Harvest and Hardwood Forests Inventory and Timber Harvest to Improve Co-Management of the Forests of Eastern United States

The roots of American ginseng have been harvested from the hardwood forests of the eastern United States, alongside timber, since the mid-1700s. Very little is known about this non-timber commodity relative to timber, although significant volumes of ginseng root have been harvested from the same forests along with timber. The harvest of ginseng correlated positively and significantly with hardwood forest area, hardwood growing stock volume, and timber removals. Also, it correlated with hardwood growing stock on public forestlands in the region. The annual wholesale value of American ginseng was estimated at approximately $26.9 million compared to annual stumpage value of harvested hardwood timber of just over $1.27 billion. The volume of ginseng root harvested from natural forests represents substantial extraction of biomass, and the associated value represents substantial income for people living in an economically marginalized region. Co-management of eastern hardwood forests for timber and non-timber forest products could improve local economies and better conserve the biodiversity of these forests.     

Growing American ginseng in maple forests as an alternative land-use system in Québec, Canada

American ginseng (Panax quinquefolium) is a medicinal crop which provides tens of millions of dollars in income every year for Canadian farmers. Most of the ginseng roots are produced in open fields under expensive shade structures. Farmers need to plant ginseng at a very high density to achieve profitability. Since high planting densities are related to high disease levels, field-cultivated ginseng requires frequent applications of pesticide. Growing ginseng in forests eliminates the need of a shade structure and may reduce the need for pesticides. Thus, an experiment was performed in a maple (Acer rubrum) forest in Québec to evaluate the effects of nutrient inputs such as lime or compost on ginseng development. Ginseng emergence and survival rates, leaf area and foliar and root weight were evaluated for each treatment. Soil samples were taken in each plot to determine the concentration of various soil nutrients. During the first two years of the experiment, it was noted that the application of lime had a significative positive effect on ginseng growth. This effect could be related to higher calcium concentration and/or lower aluminium toxicity. Liming would be an efficient way to improve the early development of ginseng in maple forests. This practice is also known to improve the health of maple stands. This revised version was published online in June 2006 with corrections to the Cover Date.
