The aim of this study was to introduce the history and development of German organic farming(Bio-dynamic Agriculture and organic agriculture) which has a worldwide reputation and initiative in organic agriculture. And also the organization of organic producer's or farmer's group such as AGOL, POB, OSL, ALOG & Schweisfurth Stiftung and its regional distribution, the basic standard of organic farming and certification system for organic food, an actual cultivated area for organic forming and organic livestock were also shortly reported. The government subsidizing programmes and Agenda 2000, the extension services for organic farming by government and private level, the research activities of organic agriculture by governmental research body(FAL) and universities, the education system for organic agriculture in the German universities(University of Bonn, Gesamthochschule Kassel, University of Hohenheim, University of Gie$\beta$en and etc) were also explained. In the conclusion it was suggested several issues what should be considered to facilitate an organic farming in Korea in the view of organic production, marketing, distributing, extension and organic processing.

To find out the process of hillslope denudation since the Last Glacial Maximum in Asan area, we conducted the stratiform interpretation and carbon age measurements with the collected samples through trenching in the valley bottom of 'Agol' located in the lower stream of Magok stream. The results are as follows. 11 inorganic and 8 organic matter layers were confirmed at the point of trench MG1 in the subject area, 7 inorganic and 3 organic at the point of trench MG2, and 5 inorganic and 3 organic at the point of trench MG3, respectively. The frequency of hillslope denudation, hillslope mass movement, which had occurred in the unstable environment of back hillslope at the point of MG 1, was 11 times (8 times before about 2,900yrBP, twice in between about 2,900~1,900yrBP, and once after about 1,900yrBP) as a whole. The frequency of moor which had formed in the comparatively stable environment of back hillslope was 9 times (5 times before about 3,000yrBP, twice in between 3,000~2,800yrBP, and once in between 2,200~1,900yrBP) at minimum. The frequency of back hillslope denudation at the point of MG2 was totally 7 times (4 times before about 1,900yrBP and 3 times after about 1,900yrBP) and the moor formations were 3 times (twice before about 1,900yrBP and once after 1,900yrBP). The frequency of back hillslope denudation at the point of MG3 was totally 5 times (3 times before about 1,900yrBP and twice after about 1,900yrBP) and the moor formations were 3 times (twice before about 1,900yrBP and once after 1,900yrBP). The hillslope surrounded by valley bottom of 'Agol' was confirmed as the pile up of various inorganic matters by the mass movement such as sand or sandy gravel in the valley bottom of the subject area, formed not once but several times of denudation. We could know that the hillslope denudation cycle converged to the time period of $10^2{\sim}10^3$ years. These results will be an important basic data for restoring hillslope denudation process near Asan and changing climate of the Late Quaternary Period.
