A Rapid and Simple Manifold to Study Exchangeable Cations and Cation Exchange Capacity in 24 Soil Samples Simultaneously
(Taylor & Francis, 2020)The outcomes of this work highlight the development and validation of a rapid and simple manifold for determination of exchangeable cations [calcium (Ca), magnesium (Mg), sodium (Na), and potassium (K)] and cation exchange ... -
Aggregation kinetics of humic acids in the presence of calcium ions
(2013)The aggregation kinetics of a humic acid (HA) sample as a function of Ca2+ concentration at pH 5, 7 and 9 was investigated. UV–VIS spectroscopy was employed to quantify the progress of the aggregation reaction, and ... -
Analytical methods assessment for exchangeable cations analysis in soil: MIP OES appraisement
(Taylor & Francis, 2020-09-21)Soil monitoring and research often requires a comparison of laboratory data generated by diverse instruments and in different laboratories to demonstrate the reliability and accuracy of the results. The outcomes of this ... -
Análisis del carbono total, orgánico e inorgánico en suelos de la región semiárida pampeana argentina = Assessment of total, organic and inorganic carbon in soils of semiarid argentinian pampas
(Asociación Argentina de la Ciencia del Suelo, 2016)Existe una fuerte motivación por el desarrollo de métodos precisos y exactos para determinar carbono (C) en suelos, debido a la importancia agronómica y medioambiental de este elemento. En suelos calcáreos el C total (CT) ... -
Efecto de las pasturas perennes en la fertilidad física y biológica en molisoles de la región semiárida pampeana
(Asociación Argentina Ciencias del Suelo, 2020-07-01)El estudio tuvo como finalidad caracterizar el sistema poroso en diferentes usos del suelo y determinar si los indicadores físico hídricos bajo el planteo mixto de rotación (cultivos anuales-pasturas), se aproximan a los ... -
Efectos de las pasturas perennes en la estructura de molisoles, de la región semiárida pampeana
(Asociación Argentina de la Ciencia del Suelo, 2021-12-15)El presente trabajo tiene como objetivo evaluar la condición estructural de suelos influenciados por distintas prácticas de uso. El estudio se desarrolló en la Región Semiárida Pampeana sobre Paleustoles petrocálcicos, se ... -
Evaluación de indicadores biológicos en suelos de la región semiárida pampeana central = Evaluation of biological indicators in soils of the central semiarid Pampa region
(Asociación Argentina de Ecología, 2018-04)En la región semiárida pampeana aún no se han usado indicadores biológicos para valorar cambios en la calidad del suelo relacionados con el uso de la tierra. El objetivo de este trabajo fue caracterizar, evaluar y obtener ... -
From science to practice: The AGSUS protocol for monitoring and certification of sustainable soil management and carbon sequestration
(Elsevier, 2024-09)Sustainable soil management is indispensable for achieving the UN Sustainable Development goals and soil carbon sequestration for climate change mitigation has gained importance in recent years, yet there are few examples ... -
Influencia de factores edafo/climáticos sobre poblaciones microbianas de suelos áridos con agricultura bajo riego
(Universidad Nacional del Comahue, 2021-12-28)El objetivo de este trabajo exploratorio fue evaluar el efecto de las prácticas agrícolas a largo plazo (30 años) sobre la actividad y los aspectos estructurales de la comunidad microbiana de los suelos áridos con agricultura ... -
Land-use change affects soil hydro-physical properties in Mollisols of semiarid Central Argentina
(Elsevier, 2021-06-01)The objective of the present study was to describe the relationships between soil physical properties and to identify variables that determine the pore system and hydrological functions which are specifically important in ... -
Medición de cationes intercambiables en suelos afectados por sales de la Región Semiárida Pampeana
(Asociación Argentina Ciencia del Suelo, 2023-06)La determinación de cationes intercambiables en suelos salinos y/o sódicos, por extracción con acetato de amonio, no permite distinguir las proporciones de cationes intercambiables de sus formas solubles. Para cuantificar ... -
Patrones de índice verde normalizado (IVN) en pastizales de la provincia de Buenos Aires: su asociación con comunidades vegetales y suelos
(2014-12)A partir de información satelital histórica (MODIS 2000-2010), se identificaron patrones anuales de índice verde normalizado (IVN) pertenecientes a áreas ocupadas por pastizales o pasturas de la Pampa Deprimida, y se asoció ... -
