Characterization of potential CO2 emissions in agricultural areas using magnetic susceptibility Scientia Agricola
Leal,Fábio Tiraboschi; França,Ana Beatriz Coelho; Siqueira,Diego Silva; Teixeira,Daniel De Bortoli; Marques Júnior,José; Scala Júnior,Newton La.
ABSTRACTSoil CO2 emissions (fCO2) in agricultural areas have been widely studied in global climate change research, but its characterization and quantification are restricted to small areas. Because spatial and time variability affect emissions, tools need to be developed to predict fCO2 for large areas. This study aimed to investigate soil magnetic susceptibility (MS) and its correlation with fCO2 in an agricultural environment. The experiment was carried out on a Typic Eutrudox located in Guariba-SP, Brazil. Results showed that there was negative spatial correlation between fCO2 and the magnetic susceptibility of Air Dried Soil (MSADS) up to 34.3 m distant. However, the fCO2 had no significant correlation with MSADS, magnetic susceptibility of sand...

Chemical and biochemical properties of Araucaria angustifolia (Bert.) Ktze. forest soils in the state of São Paulo Rev. Bras. Ciênc. Solo
Carvalho,Fernanda de; Moreira,Fatima Maria de Souza; Cardoso,Elke Jurandy Bran Nogueira.
Araucaria angustifolia, commonly named Araucaria, is a Brazilian native species that is intensively exploited due to its timber quality. Therefore, Araucaria is on the list of species threatened by extinction. Despite the importance of soil for forest production, little is known about the soil properties of the highly fragmented Araucaria forests. This study was designed to investigate the use of chemical and biological properties as indicators of conservation and anthropogenic disturbance of Araucaria forests in different sampling periods. The research was carried out in two State parks of São Paulo: Parque Estadual Turístico do Alto do Ribeira and Parque Estadual de Campos de Jordão. The biochemical properties carbon and nitrogen in microbial biomass...

Crop residues on short-term CO2 emissions in sugarcane production areas REA
Corradi,Mariana M.; Panosso,Alan R.; Martins Filho,Marcílio V.; La Scala Junior,Newton.
The proper management of agricultural crop residues could produce benefits in a warmer, more drought-prone world. Field experiments were conducted in sugarcane production areas in the Southern Brazil to assess the influence of crop residues on the soil surface in short-term CO2 emissions. The study was carried out over a period of 50 days after establishing 6 plots with and without crop residues applied to the soil surface. The effects of sugarcane residues on CO2 emissions were immediate; the emissions from residue-covered plots with equivalent densities of 3 (D50) and 6 (D100) t ha-1 (dry mass) were less than those from non-covered plots (D0). Additionally, the covered fields had lower soil temperatures and higher soil moisture for most of the studied...

Celis,José E; Sandoval,Marco; Martínez,Bárbara; Quezada,Celerino.
J.E. Celis, M. Sandoval, B. Martínez, and C. Quezada. 2013. Effect of organic and mineral amendments upon soil respiration and microbial biomass in a saline-sodic soil. Cien. Inv. Agr. 40(3): 571-580. An understanding of soil carbon stocks and fluxes in saline-sodic soils is becoming critical in environmental management because salinity and sodicity are predicted to increase worldwide. The effects of amendment with sewage sludge (SW), mined gypsum (MG) and synthetic gypsum (SG) on the soil respiration rate and soil (S) microbial biomass (SMB) of a saline-sodic soil were assessed in vitro over 60 days under controlled conditions. The treatments were: T1 = S + MG (7 t ha-1); T2 = S + MG (7 t ha-1) + SW (90 t ha-1); T3 = S + SG (7 t ha-1); T4 = S + SG (7 t...

First-order decay models to describe soil C-CO2 Loss after rotary tillage Scientia Agricola
La Scala Jr.,Newton; Lopes,Afonso; Spokas,Kurt; Archer,David Walter; Reicosky,Donald.
To further understand the impact of tillage on CO2 emission, the applicability of two conceptual models was tested, which describe the CO2 emission after tillage as a function of the non-tilled emission plus a correction due to the tillage disturbance. Models assume that C in readily decomposable organic matter follows a first-order reaction kinetics equation as: dCsoil (t) / dt = -k Csoil (t), and that soil C-CO2 emission is proportional to the C decay rate in soil, where Csoil(t) is the available labile soil C (g m-2) at any time (t) and k is the decay constant (time-1). Two possible assumptions were tested to determine the tilled (F T) fluxes: the decay constants (k) of labile soil C before and after tillage are different (Model 1) or not (Model 2)....

Oliveira,Wanderson J. de; Souza,Edivan R. de; Cunha,Jailson C.; Silva,Ênio F. de F. e; Veloso,Venâncio de L..
ABSTRACT Leaf gas exchanges in plants and soil respiration are important tools for assessing the effects of salinity on the soil-plant system. An experiment was conducted with cowpea irrigated with saline water (0, 2.5, 5.0, 7.5, 10.0 and 12.5 dS m-1) prepared with two sources: NaCl and a mixture of Ca, Mg, Na, K and Cl ions in a randomized block design and a 6 x 2 factorial scheme, with four replicates, totaling 48 experimental plots. At 20 days after planting (DAP), plants were evaluated for net photosynthesis (A), stomatal conductance (gs) and transpiration (E) using the Infra-Red Gas Analyzer (Model XT6400- LICOR), and water use efficiency, intrinsic water use efficiency and instantaneous efficiency of carboxylation were calculated. At 60 DAP, the soil...

Rocha,Humberto R. da; Freitas,Helber C.; Rosolem,Rafael; Juárez,Robinson I.N.; Tannus,Rafael N.; Ligo,Marcos A.; Cabral,Osvaldo M. R.; Dias,Maria A.F. Silva.
The technique of eddy correlation was used to measure the net ecosystem exchange over a woodland savanna (Cerrado Sensu stricto) site (Gleba Pé de Gigante) in southeast Brazil. The data set included measurements of climatological variables and soil respiration using static soil chambers. Data were collected during the period from 10 October 2000 to 30 March 2002. Measured soil respiration showed average values of 4.8 molCO2 m-2s-1 year round. Its seasonal differences varied from 2 to 8 molCO2 m-2s-1 (Q10 = 4.9) during the dry (April to August) and wet season, respectively, and was concurrent with soil temperature and moisture variability. The net ecosystem CO2 flux (NEE) variability is controlled by solar radiation, temperature and air humidity on diel...

Short-term effects of byproduct amendments and lime on physicochemical and microbiological properties of acidic soil from Jiaodong Peninsula of China Ciência Rural
Shen,Yuwen; Lin,Haitao; Song,Xiaozong; Liu,Ping; Bo,Luji; Chen,Jianqiu; Yang,Li.
ABSTRACT: The influences of byproduct amendments, containing silicon, calcium, magnesium and potassium, on acidic soil quality in Jiaodong Peninsula of China had been studied and compared with that of lime through monitoring physicochemical properties and enzyme activities of acidic soil over a 120-day period. Byproduct amendments (1125, 2250, 4500 and 9000 kg ha-1) and lime 2250 kg ha-1 was applied in the acidic soil. Results showed that both byproduct amendments and lime significantly increased the pH, EC and enzyme activities of soil. The by-product amendments inhibited microbial biomass carbon and soil respiration. Nevertheless, the lime-treated soil had a much more higher level of CO2 emission than the by-product amendments-treated soil. Compared to...

Soil and crop residue CO2-C emission under tillage systems in sugarcane-producing areas of southern Brazil Scientia Agricola
Teixeira,Luís Gustavo; Corradi,Mariana Marotti; Fukuda,Adrian; Panosso,Alan Rodrigo; Reicosky,Donald; Lopes,Afonso; La Scala Jr.,Newton.
Appropriate management of agricultural crop residues could result in increases on soil organic carbon (SOC) and help to mitigate gas effect. To distinguish the contributions of SOC and sugarcane (Saccharum spp.) residues to the short-term CO2-C loss, we studied the influence of several tillage systems: heavy offset disk harrow (HO), chisel plow (CP), rotary tiller (RT), and sugarcane mill tiller (SM) in 2008, and CP, RT, SM, moldboard (MP), and subsoiler (SUB) in 2009, with and without sugarcane residues relative to no-till (NT) in the sugarcane producing region of Brazil. Soil CO2-C emissions were measured daily for two weeks after tillage using portable soil respiration systems. Daily CO2-C emissions declined after tillage regardless of tillage system....

Soil CO2 efflux in central Amazonia: environmental and methodological effects Acta Amazonica
Zanchi,Fabrício B.; Waterloo,Maarten J.; Kruijt,Bart; Kesselmeier,Jürgen; Luizão,Flávio J.; Manzi,Antônio O.; Dolman,Albertus J..
Soil respiration plays a significant role in the carbon cycle of Amazonian rainforests. Measurements of soil respiration have only been carried out in few places in the Amazon. This study investigated the effects of the method of ring insertion in the soil as well as of rainfall and spatial distribution on CO2 emission in the central Amazon region. The ring insertion effect increased the soil emission about 13-20% for sandy and loamy soils during the firsts 4-7 hours, respectively. After rainfall events below 2 mm, the soil respiration did not change, but for rainfall greater than 3 mm, after 2 hours there was a decrease in soil temperature and respiration of about 10-34% for the loamy and sand soils, with emissions returning to normal after around 15-18...

Soil CO2 emission as related to incorporation of sugarcane crop residues and aggregate breaking after rotary tiller REA
Teixeira,Luis G; Fukuda,Adrian; Panosso,Alan R; Lopes,Afonso; Scala Jr,Newton La.
Soil tillage is a process that accelerates soil organic matter decomposition transferring carbon to atmosphere, mainly in the CO2 form. In this study, the effect of rotary tillage on soil CO2 emission was investigated, including the presence of crop residues on the surface.Emissions were evaluated during 15 days after tillage in 3 plots: 1) non-tilled and without crop residues on soil surface (NTwo), 2) rotary tiller without the presence of crop residues on soil surface (RTwo), and 3) rotary tiller with the presence of crop residues in soil surface (RTw). Emissions from the RTw plot were higher than the other plots, (0.777 g CO2 m-2 h-1), with the lowest emissions recorded in the NTwo plot (0.414 g CO2 m-2 h-1). Total emission indicates that the difference...

Soil CO2 emission of sugarcane fields as affected by topography Scientia Agricola
Brito,Liziane de Figueiredo; Marques Júnior,José; Pereira,Gener Tadeu; Souza,Zigomar Menezes; La Scala Júnior,Newton.
The spatial and temporal variation of soil CO2 emission is influenced by several soil attributes related to CO2 production and its diffusion in the soil. However, few studies aiming to understand the effect of topography on the variability of CO2 emissions exist, especially for cropping areas of tropical regions. The objective of this study was to evaluate the spatial and temporal changes of soil CO2 emission and its relation to soil attributes in an area currently cropped with sugarcane under different relief forms and slope positions. Mean CO2 emissions in the studied period (seven months) varied between 0.23 and 0.71, 0.27 and 0.90, and 0.31 and 0.80 g m-2 h-1 of CO2 for concave (Conc), backslope (BackS) and footslope (FootS) positions, respectively....

Soil CO2 flux: a method comparison of closed static chambers in a sugarcane field Rev. Bras. Ciênc. Solo
Ivo,Walane Maria Pereira de Mello; Salcedo,Ignacio Hernán.
A large variety of techniques have been used to measure soil CO2 released from the soil surface, and much of the variability observed between locations must be attributed to the different methods used by the investigators. Therefore, a minimum protocol of measurement procedures should be established. The objectives of this study were (a) to compare different absorption areas, concentrations and volumes of the alkali trapping solution used in closed static chambers (CSC), and (b) to compare both, the optimized alkali trapping solution and the soda-lime trapping using CSC to measure soil respiration in sugarcane areas. Three CO2 absorption areas were evaluated (7; 15 and 20 % of the soil emission area or chamber); two volumes of NaOH (40 and 80 mL) at three...
