Amidehydrolitic activities in soil constitute a mechanism to release nitrogen easily available to plants. This paper studies two of these activities (glutaminase and asparaginase) in relation to their distribution in soil samples and their evolution during the storage in changing conditions. Both enzyme activities decreased according to the depth of the soil. Glutaminase and asparaginase activities are correlated with the organic matter content in both types of soils and with the clay presence in the Ocre Humifero soil. Storage alters considerably the activity of amidehydrolases in the samples. The magnitude of these variations is conditioned by the soil characteristics as well as by the conditions in which the storage is developed
