摘要：

A method is described that allows manipulation of soil structure as a variable in microcosm experiments while leaving other characteristics intact. The basic steps in the method are: (1) homogenization of the soil by sieving; (2) partial sterilization, to eliminate larger biota; (3) compression of a predetermined amount of soil to a certain volume. In this way, cores are produced with highly uniform soil physical characteristics. The structure may be adjusted to the needs of an experiment by varying the mesh size in sieving or the amount of soil to be compressed, by introducing artificial macropores, creating artificial barriers etc. The method has been used in experiments on the reactions of soil animals to various pore structures, studies on the changes in soil structure by structure forming animals and studies on root growth.
