Soil respiration rates, measured during the dry season of 1966 in Costa Rica by absorption of CO 2 through KOH followed by titration with HCI, were lowest in the savanna and the decidous forest (300—400 mg CO 2 /m 2 /hr); they were between 1,000 and 2,000 mg CO: 2 /m 2 /hr in the gallery forest and the wet forest; and were highest in the secondary growth vegetation (2,556 mg CO 2 /m 2 /hr). The results were related to the climatic conditions in these habitats. The climate limits the development of organisms in the soil and the primary production in the vegetation. Comparisons of European, Canadian, and tropical soil respiration rates show the limitation of soil respiration through limitations of primary productivity.
