Emissão de CO2 do solo associada à calagem em área de conversão de laranja para Cana-de-açúcar
(2014-01-01)
The soil CO2 emission (FCO2) in agricultural areas is resulting from the interaction of several factors, as amended by the practice of soil management practices and crop, in addition to the local edaphoclimatic conditions. ...
Soil carbon balance in a tropical grassland: Estimation of soil respiration and its partitioning using a semi-empirical model
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
In savannah and tropical grasslands, which account for 60% of grasslands worldwide, a large share of ecosystem carbon is located below ground due to high root:shoot ratios. Temporal variations in soil CO2 efflux (R-S) were ...
Quantification of uncertainties associated with space-time estimates of short-term soil CO2 emissions in a sugar cane area
(2013-03-01)
The characterization of soil CO2 emissions (FCO2) is important for the study of the global carbon cycle. This phenomenon presents great variability in space and time, a characteristic that makes attempts at modeling and ...
Spatial variability models of CO2 emissions from soils colonized by grass (Deschampsia antarctica) and moss (Sanionia uncinata) in Admiralty Bay, King George Island
(Cambridge University Press, 2011-02-01)
Soil CO2 emission is an important part of the terrestrial carbon cycling and is influenced by several factors, such as type and distribution of vegetation. In this work we evaluated the spatial variability of soil CO2 ...

Soil tillage and cover crop on soil CO2 emissions from sugarcane fields
(2019-06-01)
Soil tillage is an agricultural practice that directly affects the global carbon cycle. Our study sought to assess the implications of adopting sunn hemp cover crops with different tillage practices on CO2 emissions for ...
COMPARACIÓN DE LOS EFECTOS EJERCIDOS POR LOS BIOFERTILIZANTES, LOS FERTILIZANTES NPK Y LOS MÉTODOS DE CULTIVO SOBRE LA RESPIRACIÓN DEL SUELO EN EL SUELO DE CHERNOZEM
(2020-09)
La respiración del suelo es un indicador importante de la actividad microbiana; los procesos de respiración y descomposición
del suelo a nivel mundial liberan anualmente a la atmósfera un total de 220 mil millones de ...
Altered soil carbon dynamics under different land-use regimes in subtropical seasonally-dry forests of central Argentina
(Springer, 2016-06)
Background and aims Subtropical seasonally dry forestsfrom South America are now experiencing one ofthe highest rates of forest-cover change globally. Thesechanges may affect the dynamics of soil organic carbon(SOC) including ...
Microbial Respiration in Soils of the Argentine Pampas after Metsulfuron Methyl, 2,4‐D, and Glyphosate Treatments
(Taylor & Francis, 2008-02)
Short-term response of microbial respiration after treatment with different doses of the herbicides mesulfuronmethyl (MET), 2,4-D, and glyphosate (GLY) was studied in microcosms of soils collected in three agricultural ...
