 note = {Three subjects such as "High quality of products", "High production at low cost "and" Promotion of sustainable agriculture as well as preserve the environment" are exist in upland farming of Tokachi district located east-part of Hokkaido in the northern Japan. It is impor-tant to take countermeasures such as improve-ment project of the land basis, soil fertility management and fertilizing technology, crop rotation plan basd on the productivity of up-land soil to cope with upper subjects. For that purpose, in the first place, it is needs to estimate the irregular conditions of soil productivity as it is per unit field accu-rately and swiftly. Then it is also needs to es-timate the soil productivity generally by overlaying the components and to establish the soil management techniques based on its re-sult. The present research have three aims as follows ; (1) To develope the method for seizing the soil productivity components such as soil organic matter (OM) content, soil moisture ch-racteristics (SMC for example available mois-ture holding capacity etc), and gravelly layer's depth (GLD) over wide area and swifty using Landsat Thematic Mapper (TM) observational data. (2) To develope the "Agricultura Information System of Tokachi" which is capa-ble to give the high degree's information gained by overlaying the few primary data such as OM, SMC and GLD for soil manage-ment. (3) To indicate a new support concerning to soil management on upland farming on both level of fermar's unit field and wide area.},
