Abstract
In order to find out the effects of soil conditioner treatment on the water movement in sandy loam and silt loam soils were treated with two different kinds of soil conditioners, hydrophobic Bitumen 0.4% or hydrophillic Uresol 0.6%, and the changes of wetting angle (soil-water contact angle), penetrability and diffusivity were measured. The results were summarized as follows: 1. Uresol 0.6% treatment decreased the wetting angle of sandy loam more than
토양개량제(土壤改良劑) 처리(處理)가 토양중(土壤中)에서 수분(水分)의 이동(移動)에 미치는 영향(影響)을 구명(究明)코져 사양토(砂壤士)와 미사질양토(微砂質壤土)에 친수성(親水性)인 Uresol과 소수성(疎水性)인 Bitumen을 처리(處理)하여 습윤각(濕潤角), 침투성(浸透性) 및 확산계수(擴散係數) 변화(變化)를 측정(測定)하였는 바 그 결과(結果)를 요약(要約)하면 다음과 같다. 1. Uresol 처리(處理)에 의하여 사양토(砂壤土) 습윤각(濕潤角)이
