Carbono de la biomasa microbiana de los suelos como indicador de cambios en sistemas productivos locales
Perez Brandan, Carolina; Huidobro, Dina Jorgelina; Alvarez, Marcos David (EEA Salta, INTA, 2020-09)La degradación del suelo constituye una de las amenazas más graves que atenta contra la sustentabilidad de los diferentes agroecosistemas de la Provincia de Salta. En este escenario, los microorganismos juegan un papel ... -
Changes in microbial and physicochemical properties under cover crop inclusion in a degraded common bean monoculture system
Aban, Carla Luciana; Perez Brandan, Carolina; Verdenelli, Romina Aylen; Huidobro, Dina Jorgelina; Meriles, José Manuel; Vargas Gil, Silvina (Elsevier, 2021-12)The expansion of the common bean monoculture system along with intensive agricultural practices focused on productivity has generated a misuse of natural resources, accompanied by a significant decline of the soil ecosystem ... -
Influence of a tropical grass (Brachiaria brizantha cv. Mulato) as cover crop on soil biochemical properties in a degraded agricultural soil
Perez Brandan, Carolina; Chavarria, Diego N.; Huidobro, Dina Jorgelina; Meriles, Jose Manuel; Perez Brandan, Cecilia Maria; Vargas Gil, Silvina (Elsevier, 2017-11)The inclusion of tropical grass forage as a cover crop (CC) could be a useful tool to improve microbiological activity and, consequently, soil quality. The aim of this study was to evaluate the effect of Brachiaria brizantha ... -
Long-term effect of tillage systems on soil microbiological, chemical and physical parameters and the incidence of charcoal rot by Macrophomina phaseolina (Tassi) Goid in soybean
Perez Brandan, Carolina; Arzeno, Jose Luis; Huidobro, Dina Jorgelina; Grumberg, Betiana Clarisa; Conforto, Erica Cinthia; Hilton, Sally; Bending, Gary D.; Meriles, Jose Manuel; Vargas Gil, Silvina (Elsevier, 2012-10)A 20-year field experiment was employed with the aim of evaluating the effect of tillage systems on biological, chemical and physical aspects of the soil, and to establish whether there was a correlation of these parameters ... -
Relationship between microbial functions and community structure following agricultural intensification in South American Chaco
Perez Brandan, Carolina; Huidobro, Dina Jorgelina; Galvan, Marta Zulema; Vargas Gil, Silvina; Meriles, Jose Manuel (Czech Academy of Agricultural Sciences, 2016-07)Intensification of agricultural systems through the use of intensive agriculture and the advance of deforestation have led to a decrease of soil biological quality. Soil functional and structural microbiota are sensitive ... -
Service crops improve a degraded monoculture system by changing common bean rhizospheric soil microbiota and reducing soil-borne fungal diseases
Aban, Carla Luciana; Verdenelli, Romina Aylén; Vargas Gil, Silvina; Huidobro, Dina Jorgelina; Meriles, José Manuel; Perez Brandan, Carolina (Oxford University Press, 2021-02)Intensive agricultural practices have resulted in progressive soil degradation, with consequences on soil ecosystem services. The inclusion of service crops is a promising alternative to support the sustainability of the ... -
Short-term service crops affect the spatial organization of soil aggregates, microbial C–N biomass, and microbial activities in a degraded monoculture system
Ducci, María Antonella; Aban, Carla Luciana; Huidobro, Dina Jorgelina; Vargas Gil, Silvina; Acreche, Martin Moises; Perez Brandan, Carolina (Elsevier, 2024-07)Service crops are grown to provide ecosystem services, such as the ability to increase soil organic matter and fertility. Also, they reduce erosion processes, weed control, disease regulation, water purification, soil ... -
Soil Properties and Bacterial Communities Associated with the Rhizosphere of the Common Bean after Using Brachiaria brizantha as a Service Crop: A 10-Year Field Experiment
Aban, Carla Luciana; Larama, Giovanni; Ducci, María Antonella; Huidobro, Dina Jorgelina; Abanto, Michel; Vargas Gil, Silvina; Perez Brandan, Carolina (MDPI, 2023-01)Intensive agricultural farming practices, such as monoculture, require long bare fallow periods and the overuse of agrochemicals, which compromise soil health over time. Increasing plant diversity in agroecosystems with ... -
Soybean fungal soil-borne diseases: a parameter for measuring the effect of agricultural intensification on soil health
Perez Brandan, Carolina; Huidobro, Dina Jorgelina; Grumberg, Betiana Clarisa; Scandiani, María Mercedes; Luque, A.G.; Meriles, Jose Manuel; Vargas Gil, Silvina (2014)The aim of this study was to investigate the influence of agricultural intensification on soil microbial diversity, chemical and physical parameters, and the decrease of the incidence of sudden death syndrome (Fusarium ... -
The effect of crop sequences on soil microbial, chemical and physical indicators and its relationship with soybean sudden death syndrome (complex of Fusarium species)
Perez Brandan, Carolina; Arzeno, Jose Luis; Huidobro, Dina Jorgelina; Conforto, Erica Cinthia; Grumberg, Betiana Clarisa; Hilton, Sally; Bending, Gary D.; Meriles, Jose Manuel; Vargas Gil, Silvina (Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2014)The effect of crop sequences on soil quality indicators and its relationship with sudden death syndrome (SDS, a complex of Fusarium species) was evaluated by physical, chemical, biochemical and molecular techniques. Regarding ...
