A first record of bulk atmospheric deposition patterns of major ions in southern South America
(Springer, 2019-09)Despite the importance of long-term atmospheric deposition of ions for vegetation productivity and biogeochemistry, southern South America lacks long-term deposition records. We report a 6-year-long record of atmospheric ... -
A New Methodological Approach to Study the Interaction of Humic Acids, Minerals and Polyvalent Cations in Soil
(Taylor & Francis, 2024-02-20)A new methodological approach of humic acid (HA) extraction is applied to study soil samples with contrasting management regimes: natural vegetation (NV) and agricultural (A). This innovative approach involves a modification ... -
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 ... -

(Facultad de Ciencias Agrarias, Universidad Nacional de Mar del Plata, 2019-03)Los objetivos de este trabajo fueron: determinar el contenido total e intercambiable de Ca, Mg, K, la CIC, la SB y a su vez caracterizar la variabilidad espacial de dichas variables en situación de manejo agrícola y prístino. ... -
Ion accumulation, water relations and osmotic adjustment in Atriplex argentina, A. crenatifolia, A. lampa and A. nummularia under saline conditions
(David Publishig, 2016-12)Salinity is a major stress that adversely affects growth and productivity in plants. There are species that tolerate this stress within the genus Atriplex. Four species, A. lampa, A. crenatifolia, A. nummularia and A. ... -
Physiological characterization of four model Lotus diploid genotypes: L. japonicus (MG20 and Gifu), L. filicaulis, and L. burttii under salt stress
(Elsevier, 2009-09-25)The genus Lotus comprises a heterogeneous group of annual and perennial species. Lotus japonicus (with MG20 and Gifu ecotypes) has been adopted as one of the model legumes in genetic and genomic studies. Other Lotus species, ...
