Comparing Multifractal Characteristics of Soil Particle Size Distributions Calculated by Mie and Fraunhofer Models From Laser Diffraction Measurements
Darder, María Liliana; Paz-González, Antonio; García-Tomillo, Aitor; Lado, Marcos; Wilson, Marcelo G. (Elsevier, 2021-01-22)[Abstract] Particle size distribution (PSD) is a basic soil property, closely related to main soil physical and chemical attributes. Soil PSD determined by laser diffraction (LD) may provide additional information to soil ... -
Espectroscopía y aprendizaje de máquinas: una combinación útil para evaluar los efectos del uso y manejo en las propiedades del suelo [Resumen]
Royer, Ana Caroline; Lado, Marcos; Ghebleh Goydaragh, Maryam; Bertocco, Tamires (Asociación Argentina de la Ciencia del Suelo, 2021)El suelo es un sistema complejo que contiene gran variedad de componentes de distinta naturaleza orgánica e inorgánica, producto de la acción combinada de distintos factores de formación. Cambios en su uso y manejo pueden ... -
Estimation of Elemental Composition of Agricultural Soils From West Azerbaijan, Iran, Using Mid-Infrared Spectral Models
Ghebleh Goydaragh, Maryam; Jafarzadeh, Ali Asghar; Shahbazi, Farzin; Oustan, Shahin; Taghizadeh-Mehrjardi, Ruhollah; Lado, Marcos (Universidade Federal de Campina Grande, 2019-04-30)[Abstract] Characterizing the elemental composition provides useful information about the weathering degree of soils. In Miandoab County, Northern Iran, this characterization was missing, and thus the objectives of this ... -
Heat-Induced Changes in Soil Water-Extractable Organic Matter Characterized Using Fluorescence and FTIR Spectroscopies Coupled With Dimensionality Reduction Methods
Lado, Marcos; Sayegh, J.; Gia-Gadñay, Alex; Ben-Hur, Menachem; Borisover, Mikhail (Elsevier, 2023)[Abstract] Water extractable organic matter (WEOM) is a very mobile and reactive soil OM fraction, critical in the translocation of carbon (C) from soils to other environmental compartments. Transformations of WEOM due to ... -
Macro-Scale Spatial Modeling Reveals the Role of Soil Organic Matter Quality in CO2 Emissions
Tavanti, Renan; Lado, Marcos; Soares, Matheus Bortolanza; Trevisan, Rodrigo; Tavanti, Tauan Rimoldi; Freddi, Onã; Montanari, Rafael; Paz-González, Antonio (Elsevier, 2023-08-04)[Abstract] Carbon dioxide (CO2) emissions from agricultural soils result from the interaction of various factors that regulate the quantity and quality of organic material. Our objective was to assess changes in soil CO2 ... -
New Insights Into the Production, Characterization and Potential Uses of Vineyard Pruning Waste Biochars
Cárdenas-Aguiar, Eliana; Gascó Guerrero, Gabriel; Lado, Marcos; Méndez Lázaro, Ana María; Paz-Ferreiro, Jorge; Paz-González, Antonio (Elsevier, 2023-10-04)[Abstract] Vineyard pruning waste (VP) can be converted into a useful char using pyrolysis as part of a valorization strategy. This study analyzed the effect of temperature (300 and 600 °C) and residence time (1 and 3 h) ... -
Past Sewage Sludge Application Did Not Alter Soil Chemical Properties or Abundance of Most Abundant Bacterial Families in an Agroforestry System
Álvarez-López, Vanessa; Lado, Marcos; Lamas, Alexandre; Vázquez, Beatriz; Mosquera-Losada, María Rosa (Elsevier, 2023-02-10)[Abstract] Forest management practices impact the amount of organic matter reaching the soil, but also the soil properties and/or vegetation composition that influence soil microbiome structure and composition. After ... -
Predicting Weathering Indices in Soils Using FTIR Spectra and Random Forest Models
Ghebleh Goydaragh, Maryam; Taghizadeh-Mehrjardi, Ruhollah; Golchin, Ahmad; Jafarzadeh, Ali Asghar; Lado, Marcos (Elsevier, 2021-05-19)[Abstract] Weathering indices based on the relative proportions of different chemical elements are a useful tool to investigate the degree of weathering of soils. This characterization is missing in West Azerbaijan, northern ... -
