Abstract:
 Salt-affected soils have  crop production in dry area. To reclaim such soils, it is important to understand temperature, salt, and water interaction. We investigated the effect of salt content on thermal enhancement faction. Three soils were mixed salt solution with in a 100cc soil sampler. Thermal properties were  with a dual-probe heat-pulse technique in a temperature-controlled room(25°C) with various atmospheric pressures(0, 40, 100, 230, and 400). The soils used were montmorillonitic, kaolinitic, and volcanic ash origin. Salt solutions used were sodium chloride, sodium sulfide, and calcium chloride. Results will be discussed.
