Última Carbon and nutrient stocks of three Fabaceae trees used for forest restoration and subjected to fertilization in Amazonia Anais da ABC (AABC) JAQUETTI,ROBERTO K.; GONÇALVES,JOSÉ FRANCISCO C.. ABSTRACT Amazonia is crucial to global carbon cycle. Deforestation continues to be one of the main causes of the release of C into the atmosphere, but forest restoration plantations can reverse this scenario. However, there is still diffuse information about the C and nutrient stocks in the vegetation biomass. We investigated the carbon and nutrient stocks of Fabaceae trees (Inga edulis, Schizolobium amazonicum and Dipteryx odorata) subjected to fertilization treatments (T1 - no fertilization; T2 - chemical; T3 - organic; and T4 - organic and chemical fertilization) in a degraded area of the Balbina Hydroelectric Dam, AM - Brazil. As an early successional species, I. edulis stocked more C and nutrients than the other two species independent of the...

Suelo Nutr. Veg. Muñoz,Cristina; Ovalle,Carlos; Zagal,Erick. The overexploitation of the natural resources in the Mediterranean-type climate region of Chile, has resulted in natural forest fragmentation and expansion of Acacia caven (Mol), forming the ‘Espinal’ ecosystem (EE) that includes two million of hectares in the Central part of Chile. The effect of the anthropogenic intervention over the soil organic carbon (SOC) in these ecosystems is unknown. The aim of this study was to quantify the SOC stocks and it profile distribution in the EE. This was achieved by collecting soils samples according to soil coverage percentage canopy from: well-preserved Espinal (WPE), 51-80 %; good-preserved (GE), 26-50 %; degraded (DE), 11-25 % and very degraded (VDE), 0-10 %. We also included a native forest (NF), 80-98 % of soil... Tipo: Journal article Palavras-chave: Acacia caven; Degraded ecosystems; Soil use intensity.
