    Analysis of humic acid from compost of urban wastes and soil by fluorescence spectroscopy by Velasco, M.I, Campitelli, P. A., Ceppi, S.B., Havel, J.

    “…Estas características están relacionadas con los procesos de biodegradación de los AH y consecuentemente con la fertilidad física y química del suelo.Las muestras de AH estudiadas fueron: AH soil standard (1S102), AH leonardit estandard (1S104H) de la Sociedad Internacional de Sustancia Húmicas (IHSS),AH de suelos de diferentes orígenes, de la Provincia de Córdoba, Argentina y AH derivados de compost.Los AH de suelo estudiados tienen, según los espectros de fluorescencia, el siguiente tamaño molecular y/o carácter aromático: Gramma < Pastizal < Desmonte< Algarrobo < Leonardite < Soil standard; con lo cual los AH de suelos de la provincia de Córdoba, Argentina, son más fácilmente biodegradables en el medio ambiente del suelo. …”

    Quantification of the effects of agricultural machinery traffic on soil and sunflower yields (Helianthus annuus L.) by Botta, Guido Fernando, Romay, Catalina, Rivero, Ezequiel Ricardo David, Ezquerra Canalejo, Alejandra, Ghelfi, Diego Gabriel, Hidalgo, Ramón Jesús

    Published 2024
    “…Seeds germination and crop productions depend mostly on the planting methods used, initial soil mechanical conditions and soil moisture. The main objective of this work was to quantify the agricultural traffic effects on soil compaction, sunflower (Helianthus annuus L.) seed emergence and yield under two different soil mechanical conditions: No-tillage (NT) and conventional tillage (CT). …”
