Abstract
The soil management practices before transplanting the ginseng plant were studied with two organic matter sources such as a traditional organic matter (wild grass) and commercial organic fertilizer (byproducts of amino acid fermantation) during the late spring to late autumn. During the soil management practices, the soil received 40kg N/10a from five different combination treatments with above two organic matter sources, a wild grass and a commercial organic fertilizer. After the application of the treatments, the soil were ploughed regularly at the interval of 20 days and the changes of physicochemical properties during the soil management practices were investigated. The next year after soil management practices, ginseng plants were transplanted to each treatment, growth and the content of some organic components of ginseng plant were measured for comparision of the different treatments. 1. The decrease in bulk density observed during the first 40 days of management was considered to be the effect of the improved physical conditions caused by ploughing, The decrease in bulk density observed after 40 days of management was considered to be the effect of organic matter. Similar results were observed in particle density, however porosity increased with time. 2. Soil pH tended to decrease during the first 40 days of management, after which period the pH increased and was stabilized. However, CEC increased with organic matter treatment and the exchangeable
