N2 - In some of the drainage waters in Hachirogata reclaimed land, a very high concentration of inorganic P (up to 2 mg P L-1) has been recently detected (Sato et al. unpublished). The drainage waters flow into the Lake Hachirogata that surrounds the land. Since the lake is also a reservoir, the water circulates through a closed system. Recently, the eutrophication of the lake has been found to be significant (Akita Prefectural Government 1989) and drainage water has been incriminated as one of the P sources of eutrophication. Therefore, it would be important to analyze the mechanisms responsible for the increase of P release from Hachirogata reclaimed land.
