25. Physical Properties and Crop Management for Corn in an Albaqualf
ABSTRACT Rice monoculture in lowlands can cause problems for management practices in crop fields, for example, in weed control. For this reason, corn in rotation with irrigated rice in lowlands may be advantageous, despite problems with soil compaction and water excess. The objective of this study was to evaluate soil physical properties and corn performance

26. Water Erosion in Different Slope Lengths on Bare Soil
ABSTRACT Water erosion degrades the soil and contaminates the environment, and one influential factor on erosion is slope length. The aim of this study was to quantify losses of soil (SL) and water (WL) in a Humic Cambisol in a field experiment under natural rainfall conditions from July 4, 2014 to June 18, 2015 in individual events of 41 erosive rains in th

27. Reclamation of a Degraded Coal-Mining Area with Perennial Cover Crops
ABSTRACT: Studies addressing the potential of grass roots in improving the structural quality of constructed minesoils are not frequent in the literature, although they are essential for understanding the re-establishment of soil functions in the environment. The objective of this study was to quantify the root attributes of the species Urochloa humidicola,

28. Effect of biologically treated petroleum sludge on seed germination and seedling growth of Vigna unguiculata (L.) Walp. (Fabaceae)
The present investigation was carried out to study the response of different concentrations of treated petroleum sludge on seed germination, root and shoot length and tolerance of Vigna unguiculata (L.) Walp. The biologically treated petroleum sludge with bacterial consortium showed 54.8% reduction in total petroleum hydrocarbons. Treated sludge was utilized

29. Texture and organic carbon contents do not impact amount of carbon protected in Malagasy soils
Soil organic carbon (SOC) is usually said to be well correlated with soil texture and soil aggregation. These relations generally suggest a physical and physicochemical protection of SOC within soil aggregates and on soil fine particles, respectively. Because there are few experimental evidences of these relations on tropical soils, we tested the relations o

30. Efeitos da espacialização da cobertura florestal e da profundidade dos solos na produção de água de uma bacia hidrográfica / Effects of the spatial distribution of forest cover and the soil depth in water yield of a watershed
Several works related to the theme of water production are being made, having in common the association of forest cover with runoff in watersheds. However, no studies were found where the places where this land cover has optimum effect, because it is dependent on climatic and physiographic conditions of each watershed. The objective of this study is to evalu

31. Estudo morfológico e hidroquímico de pequenas depressões na Nhecolândia, Pantanal, MS / Morphological and hydrochemical study of small depressions in Nhecolândia, Pantanal, MS
The southern part of the Taquari alluvial fan, called Nhecolândia, is a sub-region of the Pantanal of Mato-Grosso exhibiting a complex of round shape lakes, draining fields, forested sandy areas, small watercourses and small depressions. Former studies have shown that the sub-superficial water fluxes depend on the intensity of the flood and on the presence

33. AvaliaÃÃo do Impacto das MudanÃas ClimÃticas na Oferta HÃdrica da Bacia HidrogrÃfica do ReservatÃrio Ãros usando os Modelos de MudanÃas ClimÃticas do IPCC-AR4, levando em ConsideraÃÃo as Diversas Incertezas Associadas / Evaluation of the Impact of Climate Change on Water Supply Watershed Reservoir Models using Ãros Climate Change IPCC-AR4, taking into consideration the Various Uncertainties Associated
In the present work flow projections for the basin Ãros (CearÃ) were obtained using the precipitation of global models of the fourth report of the Intergovernmental Panel on Climate Change (IPCC-AR4) for the period 2010 to 2099 the A1B scenario. The flows were generated by the hydrologic model Soil Moisture Account Procedure (SMAP). To obtain these, the pr

34. Utilização da técnica de co-krigagem com inclinação máxima e altitude do terreno no delineamento de zonas de manejo: granulometria do solo e disponibilidade hídrica / Using the technique of cokriging with maximum slope of the terrain and altitude in the delineation of management zones: grain size and soil water availability
In Brazil, few studied are related about soil sampling strategies in areas with more than one type soil and various features of the landscape, these strategies are important to map the spatial variability of physical attributes: size fractions, as well as the correlation of these with geomorphologic parameters: altitude and maximum slope of the sampled area

36. Atributos físicos do solo, produção de biomassa e balanço energético em sistema de integração lavoura-pecuária leiteira sob plantio direto / Soil physical attributes, production of biomass and energy balance in system integration crop livestock dairy in tillage
The integrated crop-livestock allow a series of advantages, but the intensive land use without technical criteria regarding the grazing pressure and machinery traffic can bring damage to soil physical quality, as manifested by compression. In these more intensive systems of production there is growing concern in relation to energy balance. The large amount o
