PROBLEM TO BE SOLVED: To provide a soil diagnosis tool capable of easily and exactly diagnosing resolution of biodegradable resin included in soil to be diagnosed; and also to provide a soil diagnosis method, a manufacturing method and usage of the soil diagnosis tool. SOLUTION: The soil diagnosis tool 100 has a diagnosis member group including diagnosis members 1 and 2 containing different biodegradable resins. Preferably, the diagnosis members are removably held by a holding member 10 made of non-biodegradable material. Preferably, the surfaces of the diagnosis members are covered with permeable protection films having a pore for suppressing permeation of soil grains and allowing permeation of microorganisms in a soil sample. Preferably, this tool further has a culture medium. The culture medium may be arranged on the surface of the diagnosis member or arranged spaced from the surface. One of the diagnosis member and the culture medium moves toward the other, thereby providing a contactable state with the surface of the diagnosis member. COPYRIGHT: (C)2007,JPO&INPIT
