Zentmyer's method (1955) is the most famous laboratory method for testing soil pesticides. In 1962 I reported that grass-cup, hizex-film, grass-ring and pile up of column methods were better than Zentmyer's method. Now the grass-ring's method is widely used in Japan. But the destruction of soil structures is limitation in the methods. To improve this disadvantage I devised a new soil sampling tube. This tube reaches a depth of 10cm passing through the lawn structure without destroying lawn and soil structures. This soil samples are usualy transplanted into grass rings, but from economical view point I utilized used aluminum beverage cans instead of grass rings. Compared with the coventional methods, this new method obtains a similar result with that obtained in the field test.
