The Standing Crop and Edaphic Factor of Grasslands in Chuiwon near the D.M.Z.

We study on the standing crop and edaphic factor of grasslands in Chulwon near the D.M.Z. The widespread and most abundant grasses are Arundinella hirta and Miscanthus sinensis in the upland fields of D.M.Z. The vascular flora of grasslands in Umi-dong and Sukda-dong near the D.M.Z. and composed of total 25 species, the most important of which ace Arundinella hirta and Miscanthus sinensis These two species contribute greatly to the standing crop of live naterial was in excess of $107.6g /m^2$. Correlation between standing ccop and water content, organic matter, total nitrogen, or avail-able phosphorus of grassland soils in area studied is high significant. It is argued that these edaphic factors affect the growth of grasses in Umi-dong and Sukda-dong grasslands.
