Abstract

This study was crried out in order to changes of soil salinity in the Kyehwa saline paddy soil from 1978 find out the to 1988. Surveyed soil was Munpo, Gwanghwal, Yeompo, Hasa series and distribution ratio of those area was 51.2%, 16.6 %, 30.2 %, 1.0 % respectively on the 2,500ha. In the cultivated field, the ratio of desalinization was increased in accordance with rice cultivating years but desalization was not conduct after six years in the uncultivated field. Soil salinity of Summer(during cultivation) and Fall(after cultivation) were 52.3 %, 62.5 % respectively as compare with Spring(before cultivating) and about changes of soil salinity according to different soil depth, underground layer 20-40cm and 40-60cm were raised the rate 28.4 % and 66.2 % in accordance with top soil.
