[Agricultural and Fisheries Newspaper = Reporter Na-ra Park] Chungnam Province is taking full steps to scientifically identify the causes of continuous cropping obstacles in order to establish a stable production foundation for Liriope muscari, its representative medicinal crop. On the 26th, the Chungnam Agricultural Technology Institute (Director Kim Young) announced that it has begun research to scientifically determine the causes of 'continuous cropping obstacles' that occur when crops are repeatedly cultivated in the same field, resulting in growth decline and yield reduction. In particular, root rot disease and growth stagnation frequently occurring in Liriope muscari will be the main subjects of investigation. Continuous cropping obstacles are generally caused by complex factors such as increased density of pathogenic microorganisms, nutrient imbalance in soil, and organic matter deficiency.
