Chlorantraniliprole: bioactivation in coffee seedlings and control of resistant Leucoptera coffeella populations

Pest Management Science, EarlyView.
Chlorantraniliprole enhanced growth and biomass in coffee seedlings infested by susceptible Leucoptera coffeella, while resistant populations limited its insecticidal performance. These findings emphasize both the bioactivator potential of chlorantraniliprole and the challenges of managing resistance in coffee leaf miner control.

Soil carbon stock and physical attributes under land‐use chronosequence in the Brazilian Cerrado

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Land‐use changes impact soil physical quality and carbon stocks. Most studies evaluating the conversion of native Brazilian Cerrado to agriculture focus on surface soil layers (up to 40 cm), with fewer examining deeper layers (0–100 cm). This study assessed the impacts of different land‐use systems on soil physical attributes and soil organic ...

Lixiviação de aldicarbe em macrolisímetros de dois Latossolos [PDF]

Pesquisa Agropecuária Brasileira, 2005
O objetivo deste trabalho foi avaliar a lixiviação do inseticida aldicarbe em macrolisímetros contendo material indeformado dos solos Latossolo Vermelho distroférrico (LVdf) e Latossolo Vermelho-Amarelo distrófico (LVAd), em condições de campo. Uma formulação granulada de aldicarbe foi aplicada na dose recomendada, a 5 cm de profundidade, em lisímetros

Data fusion of gamma and x‐ray spectra via Common Dimensions for soil erosion characterization

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract This study explores the synergistic application of energy dispersive x‐ray fluorescence (EDXRF) and gamma‐ray spectrometry (GRS) raw spectra to characterize soil redistribution. The evaluation employs Common Dimensions (ComDim), a multiblock non‐supervised machine‐learning technique, to identify shared latent patterns across nuclear and atomic

Avaliação de Latossolo pelo método de Proctor

Journal of Hyperspectral Remote Sensing, 2019
Na resolução de muitos problemas de engenharia é necessário melhorar as características do solo, de maneira a assegurar que seja capaz de suportar as cargas aplicadas sem deformação excessiva, mantendo a sua resistência e estabilidade, dessa forma é fundamental gerar informações técnicas para auxiliar os engenheiros na tomada de decisão.

Pedotransfer functions for estimating the maximum bulk density of major Brazilian agricultural soils: Model comparison and validation

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract The Proctor compaction test is the standard method for determining the maximum bulk density (Dbmax) of a soil, a key parameter for obtaining the degree of compaction. However, this method is labor‐intensive and time‐consuming, making it impractical for routine soil quality assessment.

Unlocking Sulfur Availability: How Soil pH Can Boost Nutrient Access in Tropical and Subtropical Oxisols—An Incubation Study

Soil Use and Management, Volume 42, Issue 3, July‐September 2026.
ABSTRACT Sulfur (S) plays an important role in crop development and is stored both in the structure of soil organic compounds and as sulfate ions bound to the surfaces of clay minerals. In tropical and subtropical soils rich in clay minerals and iron/aluminium oxides, soil pH strongly influences the immediate availability of S because of its influence ...

Subsoil Carbon and δ13C Spatial Patterns Reveal Land Use Legacy in a Sandy Subtropical Ecotone in Brazil

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract Soil organic carbon (SOC) storage represents one of the most critical ecosystem services provided by soils, yet scientific assessments frequently focus on surface layers, overlooking deeper horizons. In this study, we investigated SOC stocks and spatial patterns of soil δ13C across three contrasting land use and land cover (LULC) types in ...
