Reclaimed lands, including reclaimed tidelands, usually have poor soil conditions, such as low nutrient and organic matter contents and poor soil structures, which hamper adaptation and survival of newly transplanted tree seedlings. Nutrient loading technique is the concept of accumulating more nutrient in plant parts while maintaining biomass, which can increase growth and survival rates after transplanting in nutrient poor soils. However, possibility of nutrient loading on domestic tree species has not been evaluated in Korea. This study was conducted to test and select the optimum nutrient loading models for domestic tree species. Three nutrient loading models, including conventional (constant fertilizer dose), exponential (increasing fertilizer dose as exponential curve), and modified exponential (exponential increase but compensate initial fertilization), were tested for three tree species; Pinus thunbergii, Quercus acutissima, and Zelkova serrata. Seedlings were grown in a greenhouse from June to September in 2020, and selected amount of fertilizer was applied weekly. Three seedlings were collected randomly every 4 weeks in each tree species and nutrient loading model, and dry matter and nitrogen (N) concentration in each part, including root, stem, and leaf, were analyze...
