Climate and microclimate are concepts used in the characterization of an environment. The interaction between an object and its environment depends on the microclimate of the latter. The microclimate, on the other hand, is often considerably influenced by the presence of the object. Plants, for instance, by shading the soil surface, modify soil temperature and this may influence soil moisture relations and cause further changes in the soil or more precisely in the plant-soil system.
