Shamoh area is located east-north part of Hokkaido prefecture and suger beet field widely spread between Shari town and Abasiri city. Suger beet was damaged by dry weather in 1984, and was not so damaged in 1988. In this paper, we analyze the suger beet yields and make yields map in 1984 and 1988 using satellite data, Landsat MSS and TM. Next, we analyze soil water contents and soil humid in the field using Landsat TM. As a result, Typic Brown Lowland soils can estimate soil water contents, but Stratic Regosolic Andosols cannot. Soil humid can be estimated and we make distribution map. Using suger beet yields map, soil humid map and soil map, we analyze the relation of soil type and yields. As a result, soil types which are damaged heavily by dry weather compared usual year are distinguished.
