1. Soil carbon stock and humification in pastures under different levels of intensification in Brazil
ABSTRACT: Intensive management of tropical pastures has shown potential for greenhouse gas (GHG) mitigation due to high forage production and C accumulation in the soil. This study aimed to evaluate different pasture management options in relation to their effect on soil C stocks and soil organic matter (SOM) humification. Pastures in four beef cattle produc

2. USE OF USLE/ GIS TECHNOLOGY FOR IDENTIFYING CRITERIA FOR MONITORING SOIL EROSION LOSSES IN AGRICULTURAL AREAS
ABSTRACT The assessment of land use and occupation is essential for predicting soil loss due to water erosion. The objective of this study was to determine criteria for monitoring soil loss in agricultural areas using the Universal Soil Loss Equation (USLE). Soil loss data were intersected with USLE factors and slope using geoprocessing techniques for the Sa

3. Soil Compressibility under Irrigated Perennial and Annual Crops in a Semi-Arid Environment
ABSTRACT In irrigated soils, a continuous state of high moisture reduces resistance of the soil to applied external forces, favouring compaction. The aim of this study was to evaluate the susceptibility to compaction of developed calcareous soils in irrigated annual and perennial cropping systems of the Apodi Plateau, located in the Brazilian semi-arid regio

4. PRODUCTIVITY AND NUTRITIVE VALUE OF TIFTON 85 IN SUMMER, WITH AND WITHOUT IRRIGATION UNDER DIFFERENT NITROGEN DOSES
ABSTRACT The pasture irrigation has expanded, mostly in small areas in order to boost the production system, along with the use of soil improvement techniques and high-productivity grasses. Thus, this study, carried out on a small dairy farm property, aimed to evaluate the productivity, botanical composition and nutritive value of Tifton 85 with different ni

5. Avaliação econômica da terminação de bovinos em pastagem irrigada / Economic evaluation of finishing of cattle in irrigated pasture
The adoption of new technologies with the aim of intensifying the production of beef cattle has increased in recent years. Irrigation of pasture is one of these alternatives on the rise and this study aimed to determine the economic viability of finishing cattle by measuring the production costs and financial indicators. This study evaluated three production

6. Parâmetros produtivos do uso de pastagens temperadas irrigadas na terminação de bovinos de corte / Productive parameters in irrigated pastures use in the finishing beef cattle
The productive parameters of the three production pasture system irrigated based (S1, S2 and S3) in the finishing beef cattle were evaluated at South Brazil. The experimental period was from October, 2010 until September, 2011. The pasture growth (PG; KgDM/ha/d), forage accumulate (FA; KgDM/ha), stocking rate (SR; kgLW/ha/y), animal performance (ADG; kg/an/d

7. Análise da Paisagem da Bacia Hidrográfica do Rio Tijucas, SC: Proposta de Áreas Prioritárias para um Sistema de Unidades de Conservação
The analysis of use and land cover is one of the key steps for conducting the strategic planning of conservation of a watershed. This work aims to analyze the landscape of the River Basin Tijucas for purposes of proposed priority areas for implementation of conservation, using as tool the Geographic Information System (GIS), aiming to provide support for pro

8. Desempenho produtivo e qualidade da carne de ovinos terminados em pastagem irrigada no semiÃrido nordestino / Productive performance and meat quality of sheep finished in irrigated pasture in the northeastern semi arid
The aim of this study was to evaluate the productive performance and meat quality of animals of Santa InÃs (SI), Somalis Brasileira (SO) and Morada Nova (MN) breeds and  Dorper x  Morada Nova crossbreds (F1) finished in irrigated cultivated pasture. Breeding season was done simultaneously for SI, SO and MN breeds and half of the Morada Nova females was

9. Estoque de carbono nos solos da bacia do Rio Araguari-MG: estimativas, modelagem e cenários
The soils can act as a source or carbon sink to the atmosphere, depending on the climate conditions and, especially, the type of use and management adopted. Taking into consideration the stock/sequestration carbon potential, admittedly, attributed to several land uses, as in planted forests (Pinus and Eucaliptus), and no-till areas, as well as the efficiency

10. Soil properties for different uses in irrigated perimeter of Sertão in Pernambuco State. / Atributos do solo em função dos diferentes usos em perímetro irrigado do Sertão de Pernambuco
The semiarid Northeast Brazil, represented by the Caatinga biome is characterized as an environment of low water availability and shallow soils, which require regional scientific community, further studies directed at understanding and managing these resources, for their preservation in a sustainable way. Thus, this study aims to evaluate the chemical, physi

11. Braquiaria under irrigation in rotational grazing system and soil physical quality / IrrigaÃÃo em braquiÃria sob pastejo rotacionado e qualidade fÃsica do solo
The seasonality of forage production is a phenomenon of great importance because it is related to the indices of yield and profitability of livestock production. From that results the constant search for new forages and alternatives compatible with the several systems of production as well as the application of new technologies as pasture irrigation and fert

12. Emissões de CO2, NOx e N2O em solos sob diferentes cultivos na região do cerrado / CO2, NOx and N2O emissions from soils to the atmosphere under differente cropping systems in the cerrado region
The objective of the study was to evaluate the CO2, NO, N2O emissions from Oxisols (Latossolos) under different no-till cropping systems in the Cerrado region (Central Brazil). The results are presented in three chapters. Chapter 1 presents a study on the effects of increasing doses of nitrogen fertilizer on the fluxes of trace gases along the crop cycle of
