农业土壤是我国土壤科学当前研究的中心问题，但目前在这方面的知识还不够，诸如农业土壤在发生学上的地位、分类方法，与自然土壤的关系，以及农业土壤的研究方法等问题，都急待土壤工作者来共同解决。为此本刊今后拟在这方面辟专栏讨论，这将对我国农业土壤的研究和整个土壤科学的发展起推动作用。本期发表的刘更另同志和徐叔华同志的两篇文章，提出了农业土壤中的一些重要问题，对开展今后讨论有很多好处，希望所有土壤工作者踊跃参加讨论。
Agricultural soil is the central issue of current research in soil science in our country. However, there is not enough knowledge in this field at present, such as the academic status of agricultural soil, the classification method, the relationship with natural soil and the research methods of agricultural soil. All urgently to soil workers to work together to solve. Therefore, we intend to provide a column discussion in this respect in the future, which will promote the study of agricultural soil in China and the development of soil science as a whole. In this issue, two articles by Comrade Liu and others by Xu Shuhua put forward some important issues in agricultural soils and have many benefits for carrying out future discussions. We hope that all soil workers will actively participate in the discussion.
