CHANGES IN PHYSICAL QUALITY OF OXISOLS UNDER DIFFERENT MANAGEMENT SYSTEMS IN THE BRAZILIAN CERRADO
Provedor de dados: 70
Autores: Feitosa,Carlos E. L.; Costa,Pedro H. dos S.; Meneses,Kamila C. de; Oliveira,Ulisses C. de; Farias,Maryzélia F. de.
ABSTRACT Soil compaction in agricultural areas has greatly increased in recent decades due to intensive farming practices, including short-cycle crops and machinery intensification. This study aimed to evaluate the impacts of management systems on the physical quality of a dystrophic Yellow Oxisol, in the Cerrado region of Brazil. Treatments consisted of five soil management systems, with five replications (native forest [control], slash-and-burn agriculture, pasture, no-tillage, and conventional tillage). Data analysis was performed using a completely randomized experimental design. All systems were analyzed for soil density, macroporosity, microporosity, total porosity, hydraulic conductivity, infiltration, water retention curve, penetration resistance,...

NITROGEN FLUXES IN A NOTHOFAGUS OBLIQUA FOREST AND A PINUS RADIATA PLANTATION IN THE CENTRAL VALLEY OF SOUTHERN CHILE
Provedor de dados: 73
Autores: Oyarzún,Carlos; Godoy,Roberto; Staelens,Jeroen; Aracena,Claudia; Proschle,Juan.
Forest structure and tree species can have a significant impact on total atmospheric nitrogen (N) deposition; for example, deciduous forests have higher N requirements than coniferous forests. However, knowledge about the effect of the conversion of native Chilean vegetation cover by exotic plantations on N cycling is scarce. The aim of this study was to determine the effect of the replacement of a Nothofagus obliqua native forest by a Pinus radiata plantation in southern Chile on the chemistry of throughfall, stemflow, soil water infiltration and percolation. Pinus radiata stemflow was more acidic (pH 4.7) than precipitation (pH 5.2) and throughfall (pH 5.6), while in the Nothofagus forest stemflow and throughfall pH were 6.3 and 6.1, respectively. In the...

Moving spray-plate center-pivot sprinkler rating index for assessing runoff potential
Provedor de dados: 18
Autores: King, B.A.
Numerous moving spray-plate center-pivot sprinklers are commercially available providing a range of drop size distributions and wetted diameters. A means to quantitatively compare sprinkler choices in regards to maximizing infiltration and minimizing runoff is currently lacking. The objective of this study was to develop a soil independent quantitative runoff potential index to facilitate selection of sprinklers for center-pivot sprinkler irrigation systems. Drop sizes, velocities and water application rates of numerous moving spray-plate sprinklers were measured in the laboratory over a range of flow rates and operating pressures. The proposed sprinkler runoff index is based on application rates of kinetic energy and water computed by overlapping specific...

Infiltration model for center pivot irrigation on bare soil

The marked reduction in infiltration rate caused by formation of a soil surface seal due to water droplet impact on bare soil is a well known phenomenon but is rarely considered in infiltration models, especially under center pivot irrigation.  The objective of this study was to develop a soil infiltration model for center pivot sprinkler irrigation that incorporates the transient reduction in soil surface seal hydraulic conductivity as affected by soil and sprinkler characteristics.  A sealing soil infiltration model was developed using an explicit finite difference solution scheme with a transient soil seal formation model, which is unique from other studies in that it explicitly uses droplet specific power as the driving factor for formation of a soil...

Center pivot simulator for evaluating system design and management effects on infiltration and erosion
Provedor de dados: 18
Autores: King, B.A.; Bjorneberg, D.L.
A 4-wheeled commercial irrigation boom was modified for use in investigating center pivot design and  management effects on infiltration, runoff and erosion of specific soil types. The center pivot simulator  used a hydraulic winch attached to the front of a tractor for mobilization and controlled travel speed. A 3  inch diameter 300 ft drag hose is used to supply water to the center pivot simulator. The center pivot  simulator was used to conduct two studies to investigate infiltration, runoff and erosion differences of  common commercially available center pivot sprinkler types on a Portneuf silt loam soil. Sprinklers used  in the first study were: 1) Nelson R3000 with brown plate, 2) Nelson R3000 with red plate, 3) Nelson  S3000 with purple plate, and...

Infiltration characteristics of bare soil under sequential water application events

The marked reduction in infiltration rate caused by formation of a soil surface seal is a well known phenomenon but often ignored in infiltration models. The effect sequential water application events have on infiltration rate and soil surface seal formation has rarely been investigated. The objective of this study was to investigate the effect sequential water application events have on the infiltration rate of a Portneuf silt loam soil with and without water droplet impact. The Portneuf silt loam soil developed a soil surface seal that reduced infiltration rate both with and without droplet impact on the bare soil surface. When the soil surface was protected during the first rainfall event, drying the soil did not increase infiltration rate for...

Transient Soil Surface Sealing and Infiltration Model for Bare Soil Under Droplet Impact.
Provedor de dados: 18
Autores: King, B.A.; Bjorneberg, D.L.
The marked reduction in infiltration rate caused by formation of a soil surface seal due to water droplet impact on bare soil is a well known phenomenon but is rarely considered in infiltration models, especially under center pivot irrigation.  Water application rates under center pivot irrigation commonly exceed infiltration rate, especially near the end of the system lateral.  This can lead to off-site runoff and erosion, but more importantly results in field-scale non-uniform water infiltration that can substantially reduce water use efficiency of these irrigation systems.  The objective of this study was to develop a sealing soil infiltration model that considers transient soil seal formation on a 30 min or less time scale and can potentially be...

Sprinkler Irrigation Effects on Infiltration and Near-Surface Unsaturated Hydraulic Conductivity
Provedor de dados: 18
Autores: Lehrsch, G.A.; Kincaid, D.C.
Sprinkler irrigation alters soil hydraulic properties both at and below the soil surface, yet its effects are not well characterized. We evaluated the effects of sprinkler irrigation on infiltration and near‐surface hydraulic conductivity (K) measured under tension in a poorly structured, recently roller‐harrowed Portneuf silt loam (Durinodic Xeric Haplocalcid). The experimental design was a randomized complete block with two treatments (pre‐ and post‐irrigation) and four replications. We used two half‐circle spray heads to apply 127 mm of water at 70 mm h-1 in one irrigation to duplicate 1 × 2 m plots. Unconfined (three‐dimensional) infiltration rates at steady‐state were measured at potentials of -55, -35, and -15mm of water before and about 10 days...

Numerical analysis of the impact of charcoal production on soil hydrological behavior, runoff response and erosion susceptibility
Provedor de dados: 90
Autores: Ayodele,Ajayi; Oguntunde,Philip; Joseph,Abiodun; Dias Junior,Moacir de Souza.
The impact of charcoal production on soil hydraulic properties, runoff response and erosion susceptibility were studied in both field and simulation experiments. Core and composite samples, from 12 randomly selected sites within the catchment of Kotokosu were taken from the 0-10 cm layer of a charcoal site soil (CSS) and adjacent field soils (AFS). These samples were used to determine saturated hydraulic conductivity (Ksat), bulk density, total porosity, soil texture and color. Infiltration, surface albedo and soil surface temperature were also measured in both CSS and AFS. Measured properties were used as entries in a rainfall runoff simulation experiment on a smooth (5 % slope) plot of 25 x 25 m grids with 10 cm resolutions. Typical rainfall intensities...

Provedor de dados: 90
Autores: Lozano,Luis Alberto; Germán Soracco,Carlos; Buda,Vicente S.; Sarli,Guillermo O.; Filgueira,Roberto Raúl.
The area under the no-tillage system (NT) has been increasing over the last few years. Some authors indicate that stabilization of soil physical properties is reached after some years under NT while other authors debate this. The objective of this study was to determine the effect of the last crop in the rotation sequence (1st year: maize, 2nd year: soybean, 3rd year: wheat/soybean) on soil pore configuration and hydraulic properties in two different soils (site 1: loam, site 2: sandy loam) from the Argentinean Pampas region under long-term NT treatments in order to determine if stabilization of soil physical properties is reached apart from a specific time in the crop sequence. In addition, we compared two procedures for evaluating water-conducting...

Provedor de dados: 90
Autores: Silva,Sérgio Ricardo da; Barros,Nairam Félix de; Costa,Liovando Marciano da; Leite,Fernando Palha.
During timber exploitation in forest stands harvesting machines pass repeatedly along the same track and can cause soil compaction, which leads to soil erosion and restricted tree root growth. The level of soil compaction depends on the number of passes and weight of the wood load. This paper aimed to evaluate soil compaction and eucalyptus growth as affected by the number of passes and wood load of a forwarder. The study was carried out in Santa Maria de Itabira county, Minas Gerais State - Brazil, on a seven-year-old eucalyptus stand planted on an Oxisol. The trees were felled by chainsaw and manually removed. Plots of 144 m² (four rows 12 m long in a 3 x 2 m spacing) were then marked off for the conduction of two trials. The first tested the traffic...

ABSTRACT: Little is known about the groundwater recharge potential of weathered tropical catchments, where increasing water uptake is widespread to meet various water demands. This study aimed to estimate the volume of groundwater recharge of the Doce River Basin, Minas Gerais, Brazil. The BALSEQ model was applied to calculate the water balance over a period of two years (2007-2009). Evapotranspiration, runoff, and potential groundwater recharge (PGR) were calculated, using daily data on rainfall, potential evapotranspiration, and plant-available water. A soil survey was undertaken for all major soils occurring in the basin. Soils samples were used to determine hydraulic conductivity, bulk density, and water content at field capacity and at the permanent...

The purpose of this work was to develop a hydrological model for the simulation of the water balance in agricultural areas. The model uses a double exponential equation to represent the rainfall profile and uses the Green-Ampt-Mein-Larson equation to estimate the soil water infiltration rate. To evaluate the model, monthly and yearly rainfall and runoff data were obtained from four experimental plots located at the State University of Santa Catarina, UDESC, in the period from 2003 to 2008. The four treatments were bare soil (BS), conventional tillage (CT), minimum tillage (MT) and no-tillage (NT). The simulation was carried out using two synthetic rainfall series, one adjusted on a monthly basis (SAMB) and the other adjusted on a daily basis (SADB). The...

Role of charcoal addition on infiltration processes and soil water content characteristics of a sandy loam soil
Provedor de dados: 111
Autores: Villagra-Mendoza, Karolina.
Terra preta (TP) is a soil amendment which is enriched with powdered charcoal, with nutrient sources from organic residues, and that constitutes a resource to improve soils for sustainable land use systems (Glaser, 2007).  Terra preta-dark soil is inspired by the highly successful historic practice of soil building in the Amazon and other parts of the world.  This work involves a relatively unexplored topic: the comprehension of infiltration processes and soil water content characteristics in a sandy loam soil combined with different fractions of terra preta amendments.  This analysis contributes to a better understanding of the relationship between fractions of charcoal in terms of terra preta content and soil water holding capacity.  First, a physical...

Autores: Patle, G T.
This study aimed to estimate the constant infiltration rates from paddy growing area of a micro watershed located in the hilly state of Sikkim, India. Double ring infiltometer test was used for the field measurement of infiltration rates. The observed infiltration rates were compared with predicted values obtained by Horton, Philip, Kostiokov and Green-Ampt infiltration models. The suitability analysis of models was checked through statistical tools namely coefficient of determination and standard error and the best model was identified for the paddy fields of hill topography. The soil samples were collected for the estimation of soil moisture content, bulk density and soil texture analysis. Soil texture was sandy loam to loamy sand within the micro...

Provedor de dados: 111
Autores: Villagra-Mendoza, Karolina; Carvajal-Vanegas, Dorian; Beck-Broichsitter, Steffen; Horn, Rainer.
Biochar is considered as an option to ameliorate soil functions, by improving soil physical and hydraulic soil properties. This study investigated the effect of biochar and of wetting and drying cycles on the water infiltration at laboratory and at a hypothetical watershed scenario. In the laboratory, test samples with 2.5 and 5% (by dry mass) of a mango-wood biochar were added to a sandy and sandy loam soil material. Cumulative infiltration was determined after simulated intense wetting and drying cycles, by drying the samples at 30°C for three consecutive days. Additionally, biochar amended soil hydraulic parameters, obtained at the laboratory, were used to simulate the water discharge of a hypothetical watershed, with the Soil and Water Assessment Tool...

Extending the integrated Richards Equation method to new boundary conditions: model description and validation
Provedor de dados: 115
Autores: Yang,Dejun; Zhang,Tuqiao; Zhang,Kefeng; Lei,Shaogang.
There is a need for developing an accurate and simple method, which can be widely used in agro-hydrological models. The Integrated Richards Equation method is a good and simple method to simulate cyclic movement of water in the soil-atmosphere system. However, this method still has some unsolved problems and it is needed for further development if used in agro-hydrological simulation. In this study, the Integrated Richards Equation method was further developed for the agro-hydrological simulation by introducing the commonly used soil hydraulic functions, top and lower boundary conditions. Infiltration numerical experiments and a lab evaporation experiment were used for the validation of the model's capabilities of modelling infiltration and evaporation,...

Monitoring structures with optical fibers: infiltration detection
Provedor de dados: 42
Autores: MARCONCIN,LILIANE R.; MACHADO,ROBERTO D.; LACERDA,LUIZ A. DE; AUFLEGER,MARKUS.
ABSTRACT The use of sensors and optical fibers for monitoring structures is continuously growing. Strains, displacements, accelerations, temperatures are just a few of the monitoring possibilities. In the case of dam structures, concrete face rockfill dams constitute a type of structures where the monitoring of water infiltrations is of particular interest. In large structures of this type, opening of slab joints is a common effect of general strain distributions, but crack formation may also occur as a result of high compressive stresses, during and after the reservoir filling stage. In this context, this paper verifies, experimentally, the applicability and the response of a distributed fiber optic monitoring system in the identification of infiltration...

Provedor de dados: 56
Autores: Xavier,A.P.; Schellini,S.A.; Aragon,F.F.; Padovani,C.R.; Taga,E.M.
Non-absorbable microgranular hydroxyapatite was infiltrated into the subepidermal abdominal region of guinea pigs in order to assess the possibility of using this material to correct deficiencies in orbital volume. Microgranular hydroxyapatite (2.0 ml) was subepidermally infiltrated into the abdominal region of 20 guinea pigs. The animals were divided into four experimental groups of 5 animals each, which were killed 7 (G1), 15 (G2), 30 (G3) and 60 (G4) days after infiltration. The area and the largest and smallest diameters of the nodules formed by infiltration were evaluated at the site of infiltration and histological examination was performed. The mean granuloma area was similar in all groups. Histopathological examination showed that the material...
