1. Flumioxazin, imazethapyr and their mixture in the rhizosphere of soybean: effect on early nodulation and biological N fixation
ABSTRACT The application of flumioxazin and imazethapyr can affect the interactions between rhizobia and soybean in the rhizosphere. However, it remains unclear the effect of both herbicides, even when applied in mixture, on early nodulation and biological N fixation (BNF) in soybean, mainly related to some important biochemical traits in nodules. This study

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. INFLUENCE OF SOIL TEXTURE, CLIMATE AND VEGETATION COVER ON SECONDARY SOIL SALINIZATION IN PAMPAS PLAINS, SOUTH AMERICA
ABSTRACT Land-use change from herbaceous to woody cover -or vice versa- largely affects water fluxes, which in turn can mobilize existing salts dissolved in the soil, and thereby negatively affect soil and/or water quality and site productivity. Secondary salinization was observed after afforestation at the Northern and Eastern subregions of the Río de la P

4. Interrill erodibility of different sandy soils increases along a catena in the Caiuá Sandstone Formation
ABSTRACT Soil erosion in tropical areas is a major problem for sustainability in agriculture and soil stability. In the Northwest of Paraná, cassava crop is produced using a conventional tillage system along a catena consisting of different soil classes: Ferralsols (near the summit), Lixisols (mid-slope), and Arenosols (foot-slope). Therefore, differential

5. Different Patterns Of Nutrient Cycling In Contiguous Phytophysiognomies Of Atlantic Forest, Brazil
ABSTRACT The present study aimed to evaluate fine aboveground litterfall, deposition of nitrogen and phosphorus from total litterfall and leaf litter decomposition in areas of tall forest (Mata Alta) and low forest on sandy soils (Mussununga) in southeastern Brazil. Fine litterfall was collected monthly for two years (from June/2007 to May/2009) in 10 conica

6. 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�

7. 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

8. Water retention capacity in Arenosols and Ferralsols in a semiarid area in the state of Bahia, Brazil
Abstract: One of the most serious problems in areas indicated for irrigation projects in the Brazilian Northeast region is the occurrence of sandy soils, known to have low moisture retention, but occurring in strategic locations in terms of water supply and geographical situation, and which can be used for agricultural purposes. The objective of this study

9. Conversion of ammonium to nitrate and abundance of ammonium-oxidizing-microorganism in Tropical soils with nitrification inhibitor
ABSTRACT The use of nitrification inhibitors (NIs; dicyandiamide - DCD) is an alternative to reduce oxidation of ammonium (NH4+-N) to nitrate (NO3–-N) in the soil, reducing NO3–-N losses from fertilization practices. Based on the hypothesis that DCD reduces conversion of NH4+-N to NO3–-N in tropical soils and inhibits ammonia oxidizing microorganisms (

10. Synthesis of enriched biochar as a vehicle for phosphorus in tropical soils
RESUMO O fósforo (P) é um dos nutrientes que mais limita a produtividade agrícola, principalmente em solos tropicais. Biocarvão enriquecido tem sido proposto com o intuito de incrementar a biodisponibilidade de P e de outros nutrientes no solo. Assim, objetivou-se avaliar a disponibilidade do fósforo em biocarvão fosfatado (composto de biomassa e solo)

11. Root-knot nematode, Meloidogyne javanica, in response to soil fertilization
Resumo Nematoides-das-galhas das raízes (RKNs) Meloidogyne spp. causam perdas consideráveis na produção de hortaliças em todo o mundo. Embora o uso de nematicidas químicos seja um dos principais meios de controle de RKNs, a dependência nesses nematicidas está associada aos altos custos e impactos negativos à saúde humana e ao meio ambiente. No pres
