Foliar nutrient levels of native tree species from Central Amazonia. 2. Campina

Abstract

Adult leaves of 14 woody species were sampled in the campina at km 62 of the road Manaus - Caracaraí. The lamina were classified as to their size and analysed for N, P, K, Ca, Mg and Na. Comparing the foliar levels of the bioelements to relevant data for other neotropical woody vegetation, they are much below those of forests from geochemically richer areas (Amazon várzea and certain other floodplains, volcanic areas) and resemble the foliar bioelement levels of terra firme vegetation
