 Five elements (Cu, Fe, Mn, Pb and Zn) were quantitatively analyzed on 122 samples of grasses including fodder crops collected at five districts of the Okinawa main island. The results showed that each element differed considerably according to harvested districts and to species of grasses. Especially variation in lead content was remarkable. Compared with fodder crops produced in Japan, avreage amounts of trace elements of grasses produced in Okinawa were larger for copper and iron and smaller for manganese and zinc.
