1. Effects of different legume green manures on tropical soil microbiology after corn harvest
ABSTRACT Legume green manure is a popular practice for sustainable agriculture in tropical environments. The use of grain, forage and purely green manure legumes in a subhumid tropical area in Northeast Brazil was investigated to determine the total C and N contents and estimate C-microbial biomass, soil basal respiration, microbial and metabolic quotients,

2. Stabilization of sandy soil with high content of asphalt emulsion
Abstract The purpose of this article is to evaluate the shear strength parameters of mixtures of sandy soil with high asphalt emulsion contents for their use in geotechnical structures, such as zoned earth dams, embankments, etc. The methodology adopted consisted of: collecting and characterizing samples of sandy soil to be laboratory tested; compacting the

3. APLICAÇÃO DE NANOPARTÍCULAS DE FERRO ZERO-VALENTE (nFeZ) NA REMEDIAÇÃO DE SOLOS E ÁGUAS SUBTERRÂNEAS CONTAMINADAS: UMA REVISÃO
The remediation of contaminated soil and water is a relevant topic, being the focus of intense research. The use of nanoparticles to degrade contaminants has been consolidated as a sustainable remediation technology, with promising results worldwide. In this scenario, the zero-valent iron nanoparticles (nZVI) which, due to their properties, prove to be an im

4. Nitrogen supply to arugula from pig slurry composts in contrasting soils
RESUMO O estudo foi desenvolvido para avaliar o fornecimento de nitrogênio (N) à rúcula através de compostos obtidos por compostagem automatizada de dejetos líquidos de suínos (DLS). Durante a compostagem, xisto retortado (XR) e dicianodiamida (DCD) foram adicionados aos DLS para mitigar as perdas gasosas de N. O estudo foi realizado em casa de vegeta�

5. Use of Sunflower and Soybean as Bioindicators to Detect Atrazine Residues in Soils
RESUMO: A atrazine é seletiva para milho, cana-de-açúcar e sorgo e pode interferir em culturas sucessoras, como girassol e soja. Apesar da problemática, são poucos os estudos acerca do efeito residual desse herbicida nessas culturas. Assim, o objetivo desta pesquisa foi avaliar o efeito residual da atrazine por meio da biodisponibilidade do herbicida em

6. Micromorphology and Genesis of Soils from Topolitosequences in the Brazilian Central Plateau
ABSTRACT The micromorphology of deeply weathered soils (Ferralsols/ Latossolos ) from the Central Plateau of Brazil remains little studied, and its affiliation to different parent materials, poorly known. To clarify the processes of soil formation of these acric, gibbsitic, Fe-oxide rich Ferralsols, three lithotoposequences on local ultrabasic to basic intru

7. Field Description and Identification of Diagnostic Qualifiers for Urban Soils in Brazil
ABSTRACT Human activities often alter soils found in urban areas. These alterations affect their environmental functions and potential for use. However, soils from urban areas in Brazil have not been surveyed and identified, which can pose a technical problem for the development of the city. Considering the importance of urban environments and their soils, t

8. Aceite residual automotriz como aditivo en mezclas de hormigón: Si es factible su uso
ABSTRACT Finding a use for Automotive Residual Oil (ARO) is preponderant for society, since one liter of this liquid is capable of contaminating one million liters of drinking water, without counting the damages to agricultural soils and groundwater. The purpose of this work is to study the physical and mechanical properties of concrete by incorporating ARA

9. Phosphate Sources and Filter Cake Amendment Affecting Sugarcane Yield and Soil Phosphorus Fractions
ABSTRACT: The use of mineral phosphate fertilizers associated with organic residues can improve fertilizer use efficiency and consequently decrease their usage costs. Soil application of filter cake (FC) can provide nutrients and enhance physical quality. This study aimed to evaluate the effects of different phosphate fertilizers [rock phosphate (RP) and tri

10. Leaching of Imidazolinones in Irrigation Systems in Rice Cultivation: Sprinkling and Flooding
RESUMO: Herbicidas do grupo das imidazolinonas têm sido utilizados em arroz irrigado e apresentado longa persistência no solo, principalmente em áreas de várzea, com baixa drenagem, podendo ocasionar contaminação ambiental. Objetivou-se, com este trabalho, avaliar a lixiviação e o residual dos herbicidas pertencentes ao grupo das imidazolinonas em si

11. Persistence of auxinic herbicides applied on pasture and toxicity for succeeding crops
ABSTRACT The aim of this work was to determine the persistence of auxinic herbicides applied on tropical pasture and toxicity for succeeding crops. The herbicides were applied in an area of dystrophic red‒yellow latosol with pasture infested of weeds. At 40, 80, and 280 days after application of herbicide, the soil samples were collected at depths of 0 to

12. Copper and zinc accumulation, fractionation and migration in vineyard soils from Santa Catarina State, Brazil
ABSTRACT The purpose of this study was to evaluate Cu and Zn migration and fractions in sandy soil of vineyards. In Urussanga (SC), Brazil, soil samples were collected from a 4-year-old and 15-yearold vineyard, and from a forested area. In the soils, the chemical characteristics of Cu and Zn were analyzed by the EDTA method, which determines the fraction ava
