Composición y abundancia de poblaciones fúngicas y bacterianas y sus actividades: respuesta al manejo agroecológico
Chavarria, Diego N.; Pérez Brandan, Carolina; Serri, Dannae Lilia; Meriles, José M.; Restovich, Silvina Beatriz; Andriulo, Adrian Enrique; Jacquelin, Luis; Vargas Gil, Silvina (2017-05)La agroecología propone la autorregulación para lograr un equilibrio agrícola sustentable. Por lo tanto, considerando la rápida respuesta de las comunidades microbianas ante los pequeños cambios en el uso del suelo, el ... -
Cultivos de cobertura y bajas dosis de fertilizantes nitrogenados: efecto sobre la funcionalidad del suelo en el largo plazo
Restovich, Silvina Beatriz; Portela, Silvina Isabel; Farroni, Abel Eduardo; García Parisi, Pablo; Garcia, Leticia Soledad; Copia, Pablo Antonio; Chavarria, Diego N.; Gonzalez Anta, Gustavo; Albarracín, Daniela (2018-04)La estructura del suelo junto con los contenidos de carbono y nitrógeno son atributos críticos que condicionan el funcionamiento edáfico y promueven la resiliencia y sustentabilidad de los agroecosistemas. La glomalina, ... -
Efecto de la agriculturización sobre la calidad biológica del suelo
Serri, Dannae Lilia; Boccolini, Monica Fabiola; Oberto, Rodrigo Sebastian; Chavarria, Diego; Bustos, Ana Natalia; Vettorello, Cecilia; Apezteguía, Hernán; Miranda, Julio; Alvarez, Carolina; Galarza, Carlos Martin; Chiófalo, Sergio; Manrique, Marcela; Sueldo, Romina; Fernandez Belmonte, María Cecilia; Mattalia, Laura; Cholaky, Carmen; Vargas Gil, Silvina (Asociación Argentina Ciencias del Suelo, 2018-08-25)En la región Pampeana Argentina, la simplificación de los agroecosistemas ha ocasionado la disminución de los servicios ecosistémicos, resultando en la pérdida de recursos, y afectando la calidad del suelo. Nuestro objetivo ... -
Effect of cover crops on microbial community structure and related enzyme activities and macronutrient availability
Chavarria, Diego N.; Verdenelli, Romina Aylén; Serri, Dannae Lilia; Restovich, Silvina Beatriz; Andriulo, Adrian Enrique; Meriles, José Manuel; Vargas Gil, Silvina (2016)Continuous monoculture in major agricultural regions has been characterized by the loss of fertility, increased soil erosion and surface runoff. Thus, the inclusion of cover crops (CC) is a promising option aimed at better ... -
Influence of 12-years of NPS fertilization on soil quality, microbial community profile and activity under conservation agricultural management
Verdenelli, Romina Aylen; Chavarria, Diego N.; Dominchin, María Florencia; Rovea, Adrián; Vargas Gil, Silvina; Meriles, Jose Manuel (Asociación Argentina Ciencia del Suelo, 2018-07)Microbial parameters are considered to be potential indicators of soil quality since soil microorganisms can respond rapidly to agricultural management systems. The effect of long-term fertilizer applications on soil, ... -
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 ... -
Integrated multivariate analysis of selected soil microbial properties and their relationships with mineral fertilization management in a conservation agriculture system
Verdenelli, Romina Aylen; Conforto, Erica Cinthia; Perez Brandan, Carolina; Chavarria, Diego; Rovea, Adrián; Vargas Gil, Silvina; Meriles, Jose Manuel (Taylor & Francis, 2013)The effect of mineral fertilizer application on soil microbial community was investigated in a conservation agriculture system. The aim of this work was to evaluate how mineral fertilization with nitrogen (N), phosphorus ... -
Response of soil microbial communities to agroecological versus conventional systems of extensive agriculture
Chavarria, Diego; Perez Brandan, Carolina; Serri, Dannae Lilia; Meriles, José M.; Restovich, Silvina Beatriz; Andriulo, Adrian Enrique; Jacquelin, Luis; Vargas Gil, Silvina (2018-05)World population growth has led to a rise in resource demands imposed on agricultural systems, generating an increased global use of natural resources. However, agroecology proposes self-regulation in order to achieve a ... -
Soil microbial functionality in response to the inclusion of cover crop mixtures in agricultural systems
Chavarria, Diego N.; Verdenelli, Romina Aylén; Muñoz, Emiliano J.; Conforto, Erica Cinthia; Restovich, Silvina Beatriz; Andriulo, Adrian Enrique; Meriles, José Manuel; Vargas Gil, Silvina (2016)Agricultural systems where monoculture prevails are characterized by fertility losses and reduced contribution to ecosystem services. Including cover crops (CC) as part of an agricultural system is a promising choice in ...
