dc.descriptionSoil carbon (C) dynamics are increasingly studied because of their role in theglobal C cycle and potential influence on atmospheric carbon dioxide con-centrations and climatic changes. The substitution of native forests by cropfields usually decreases soil C stocks. However, C stocks may increase inirrigated fields of semiarid areas because high biomass production and litterincorporation may compensate for the fast turnover of organic matter. Using13C isotopic techniques, we determined soil C dynamics in the 1 m super-ficial layer, in irrigated sugarcane fields established 10 and 30 years before.From 57% to 78% of the original C stock were lost after 10 years of cultivationand from 85% to 95% after 30 years. However, these high losses were morethan compensated by sugarcane biomass inputs, and the total soil C stockincreased from 94 to 169 Mg ha-1 between 10 and 30 years of cultivation.This last C stock is higher than any reported for soils in the Brazilian semiaridregion. Therefore, substituting native dry deciduous forests by irrigatedpermanent sugarcane in semiarid areas may increase soil C stocks, contraryto most rain-fed and irrigated cropping systems with crops that accumulateless biomass than sugarcane.
