Soil organic carbon in the brazilian semi-arids tropics. The Brazilian semi-arid tropics occupies an area of 969,589 km2 that represents 11% of the national territory and the Caatinga is its most representatives Biome with an area of 844.453 km². However, a... ... Repository: BDPA Publication year: 2011
Soil chemical attributes for different land-use systems in semi arid region. Author(s): TONUCCI, R. G.; SOUZA, H. A. de Introduction the evaluation of soil fertility in already placed agroforestry systems allows inferences of greater managements practices and nutrient cycling. In the semi arid region the use of integra... ... Repository: BDPA Publication year: 2015
Losses and gains of soil organic carbon in grasslands in the Brazilian semi-arid region. Studies show that soil organic carbon (SOC) decreases between 3 % and 9 % in degraded grasslands in tropical regions, mainly due to the absence of techniques to enhance carbon contribution to soils. T... ... Repository: BDPA Publication year: 2021
Soil organic carbon temperature sensitivity of different soil types and land use systems in the Brazilian semi-arid region. Quantifying the sensitivity of soil organic matter decomposition (SOM) to global warming is critical for predict future impacts of climate change on soil organic carbon stocks (SOC) and soil respirati... ...

Critical levels and fertility classes of soils with high-activity clay in the Brazilian semi-arid region. Soil fertility evaluation is important for adopting conservation management and adequate nutrient supply. The objective of this study was to identify critical levels and soil fertility classes using t... ... Repository: BDPA Publication year: 2024
Agroforestry system improves soil carbon and nitrogen stocks in depth after land-use changes in the Brazilian semi-arid region. Author(s): TONUCCI, R. G.; POMPEU, R. C. F. F.; SOUZA, H. A. de Abstract: Agroforestry systems have the potential to increase soil organic matter, with effects on soil carbon and nitrogen contents, but information on the application of these systems in semi-arid r... ...

Land-use type effects on soil organic carbon and microbial properties in a semi-arid region of Northeast Brazil. ABSTRACT - Land-use change is one of the most important anthropogenic environmental change drivers affecting the biodiversity and functioning of ecosystems. However, there is limited knowledge of the... ... Repository: BDPA Publication year: 2016
Soil correction and Azospirillum brasilense: strategies in the cultivation of maize genotypes in semi-arid regions. Author(s): POMPEU, R. C. F. F.; FERNANDES JUNIOR, P. I.; SOUZA, H. A. de Abstract: The replacement of Caatinga by extensive agriculture has led to soil degradation in maize (Zea mays L.) growing areas. The objective of this study was to evaluate the effects of soil correct... ... Repository: BDPA Publication year: 2024
Nutrients dynamics in soil solution at the outset of notill implementation with the use of plant cocktails in Brazilian Semi-Arid. Tillage systems strongly impact nutrient transformations and plant availability. Therefore, the objective of this study was to assess the impacts of conversion of conventional tillage (CT) to no-till... ... Repository: BDPA Publication year: 2016
Coconut residues increase light fraction of organic matter and water retention in semi-arid sandy soil under irrigated cultivation. Coconut palm cultivation is associated with the generation of a large amount of residues, mainly from coconut shells, and their utilization in agriculture can represent an opportunity in the context o... ...
