Título:  Trees improve soil carbon stocks in integrated crop-livestock-forestry (ICLF) systems.

Conteúdo:  Soil organic carbon (SOC, determined with dichromate oxidation) accumulation was evaluated at three ICLF sites of different ages (2, 4 and 11 years) and soil textures (469, 198, 632 g kg-1 clay) in southern Goiás state of Brazil. SOC stocks were accessed at 0-30, 30-100 and 0-100 cm soil layers under the tree-rows and between tree-rows. SOC stocks were calculated based on equivalent soil mass, using pasture, in which the ICLFs were implemented, as reference. Our objective was to investigate the potential of trees in accumulating SOC in ICLFs. Dunnett?s test was applied to check the effect of trees on soil C stocks within each location using the linear mixed model. More SOC was measured under tree-rows at all sites and all soil layers, compared to the alley between the tree-rows, except for the youngest site (Morrinhos) at 0-30 cm. Trees, therefore, are important to maximize SOC accumulation in ICLFs. Further studies are, however, necessary to expand the database to support more robust analysis and to conclude on SOC sequestration (immobilization).

Título:  Analysis of evapotranspiration and biomass in pastures with degradation indicatives in the Upper Tocantins River Basin, in Brazilian Savanna.
Ano de publicação:  2016
Fonte/Imprenta:  Revista Ceres, v. 63, n. 6, p. 754-760, 2016.
Idioma:  Inglês
Conteúdo:  The objective of this study was to apply the Simple Algorithm For Evapotranspiration Retrieving (SAFER) with MODIS images together with meteorological data to analyze evapotranspiration (ET) and biomass production (BIO) according to indicative classes of pasture degradation in Upper Tocantins River Basin. Indicative classes of degraded pastures were obtained from the NDVI time-series (2002-2012). To estimate ET and BIO in each class, MODIS images and data from meteorological stations of the year 2012 were used. The results show that compared to not-degraded pastures, ET and BIO were different in pastures with moderate to strong degradation, mainly during water stress period. Therefore, changes in energy balance partition may occur according to the degradation levels, considering that those indicatives of degradation processes were identified in 24% of the planted pasture areas. In this context, ET and BIO estimates using remote sensing techniques can be a reliable indicator of forage availability, and large-scale aspects related to the degradation of pastures. It is expected that this knowledge may contribute to initiatives of public policies aimed at controlling the loss of production potential of pasture areas in the Upper Tocantins River Basin in the state of Goiás, Brazil.
