Non-allophanic Andisol admitted as one of the subgroup in International Andisol classification ( ICOMAND ), has strong soil acidity and is thought to be a problem soil. Therefore, both distribution and acid injury of non-allophanic Andisol were examined in this study.1) Andisol was divided into allphanic and non-allophanic Andisols by the constituent of amorphous material and was studied their chemical, physical and mineralogical properties. Both Andisols showed some common unique properties such as high amount of active Al, high accumulation of humus, low bulk density etc. Non-allopghnic Andisol showed, however, very strong soil acidity, while allphanic Andisol showed weak one.2) The acid injury of non-allophanic Andisol was clarified to be Al3+ toxicity and the degree of Al3+ saturation, the amount of exchange Al3+ and exchange acidity y1 were more useful measure of A1 toxicity in the acid Andisols compared to the amount of soil solution Al3+. Among these measurement, the y1 is most simple and practical method and 6 of y1 is worth to 2me of KCl-Al3+ which is diagnostic value differentiating alic subgroup of ICOMAND.3) Both barley and sorghum grown in non-allophanic Andisol showed symptoms of Al-toxicity and the growth of these plants was much inferior to those in allophanic Andisol. This is attributed to insufficient uptake of nitrogen due to poor rooting in the acid subsoils of non-allophanic Andisol.4) The distribution map of allophanic and non-allophanic Andisols in Tohoku district was completed. According to this map, nonallophanic Andisol was located in high rainfall region, whereas allophanic Andisols was seen in relatively low rainfall region and/or regions abundant in mafic glass or pumis.

非甘烷基Andisol被认为是国际安索分类（ICOMAND）的亚组之一，具有强烈的土壤酸度，被认为是一个问题的土壤。因此，在这项研究中检查了非磷烷二醇的分布和酸损伤。1）Andisol通过非定形材料的组成部分将其分为Allphanic和非甘烷基Andisols，并研究其化学，物理和矿物质学特性。两种Andisol都表现出一些常见的独特特性，例如高量的高度积累，腐殖质的高度积聚，低散装密度等。但是，非抗药性Andisol表现出非常强的土壤酸度，而Allphanic Andisol却较弱。与土壤溶液AL3+的量相比，A1毒性的毒性。在这些测量中，Y1是最简单，最实用的方法，Y1的6值是Kcl-Al3+的2ME，这是IComand的诊断价值区分的诊断价值。3）iComand的ALIC亚组。3）在非磷酸andisol中生长的大麦和高粱均表现出al毒性的症状，这些植物的症状与这些植物的生长和这些植物相对于那些属于Alloplanic andior andior andior andior andior andis andior andis andis andis andis andis andis andis andis andis andis andis andis andis。这归因于氮的摄取不足，这是由于在非载体安索的酸亚土壤中生根不良。4）TOHOKU地区的同泡和非磷烷andisols的分布图完成了。根据这张地图，非果植物的Andisol位于高降雨区域，而同种植物的Andisol在相对较低的降雨区域和/或含Mafic玻璃或Pumis中丰富的区域。
