Mineral Nutrient and Productivity of Three Grasslands In Kimhwa

금화 3개 지구 초지의 토양성분과 초지생산성에 관한 연구

We studied on the mineral nutrients and productivity of grasslands in Kimhwa. The vascular flora of grasslands in Sakok-ri, Wasoo-ri, and Yukdan-ri located at Kimhwa were composed of 39, 28, and 32 species respectively. The most important species were Arundinella hirta and Miscanthus sinensis These two species contributed greatly to the standing crops of live material which was in excess of $146.47g/m^2$ throughout the growing season. The daily production throughout the growing season was in excess of $1.04 g/m^2$. Factors which affected the daily productivity of grasslands in Kimhwa were phosphours and water content.
