Results of Soil Survey for Environmental-friendly Agricultural Regions in 2018

Abstract

For the improvement and conservation of sustainable environmental-friendly agriculture, governmental project for base establishment of environmental-friendly agriculture, has been done since 1999 by the ministry of agriculture, food, and rural affairs. In relation with the project, investigation on fundamental soil survey on the 16 regions of environmental-friendly agricultural area selected as project implementation area was carried out in 2018. Some of results are as follow. Distribution of soil series was identified as 96 series among 405 series in nation wide. The highest population of soil series was Jisan series occupying 10.7% of that total investigated area. The number of soil series occupying over 300 field in each soil series were 8 and the related area was 53.5% among total investigated region. Land use recommendation were paddy as 83.7% and upland as 12.9% of total agricultural area, however land use type, investigated in base of application papers were various as paddy, upland, horticulture, and orchard. Distribution of soil family were in the order of fine loamy as 39.6%, coarse loamy as 31.2%. Land slope were mostly plain (slope 0-2%) and slight slope (slope 2-7%), those occupied 82.6% of total investigated area. Distribution of drainage class of very poorly, poorly, somewhat poorly, moderately well, well and somewhat excessively was 95.9% among total investigated area.
