Experiments on the stability of potato-root diffusate in soil are described. 90% of the active principle was lost in four days in a medium grade loam. Comparative tests with soil components showed that breakdown was most rapid in sand and gravel and slowest in peat. When repeated applications of diffusate were made to a loam, successive breakdown curves were each steeper than the previous, suggesting the presence of a microorganism capable of utilising the active principle as a substrate. This was confirmed by results with sterilised loam. Newly sterilised loam inhibited the action of root diffusate but, on being allowed to stand for about six weeks, was no longer inhibitory. When diffusate was applied to loam that has been allowed to stand the breakdown was slower than in untreated soil. These results in conjunction with those in peat, tend to confirm the theory of breakdown by micro organisms.
