近十余年来,土壤电磁处理正在逐渐成为土壤改良的一个新的途径,并且为土壤学研究工作提供了新的手段。电流改土试验开始于三十年代,经过一度停顿以后,正在取得新的进展。在最近三届国际土壤学会会议上,连续介绍了土壤电改良方面的工作。与此同时,土壤的磁场处理、磁性肥料和磁性改良剂的应用,也提上了日程,许多国家都 In the recent ten years, soil electromagnetic treatment is gradually becoming a new way of soil improvement, and it provides a new method for soil science research. Current soil test began in the thirties, after a pause, is making new progress. At the recent three sessions of the International Society for Soil Science, I gave a continuous introduction of the work on soil electricity improvement. At the same time, the application of soil magnetic field treatment, magnetic fertilizers and magnetic modifiers is also on the agenda, and many countries
