Raíces de cultivos de cobertura. Cantidad, distribución e influencia sobre el n mineral = Cover crop roots: quantity, distribution and influence on soil mineral n
(Asociación Argentina de la Ciencia del Suelo, 2017)Los objetivos fueron: i) evaluar la cantidad y distribución de raíces de centeno y vicia como cultivos de cobertura (CC) y; ii) cuantificar el aporte de N de raíces en el perfil y su impacto sobre la disponibilidad de ... -
Responses of Trifolium repens L. root structure and function to shading and phosphorus shortage: limits to adaptative plasticity during establishment?
(Springer, 2023-07)Shading and low soil phosphorus availability may limit root growth of forage species in humid-temperate silvopastoral systems. However, plants are able to cope with such constraints by modifying root structure to improve ... -
Stabilization of new carbon inputs rather than old carbon decomposition determines soil organic carbon shifts following woody or herbaceous vegetation transitions
(Springer, 2016-12)Background and aims: Although numerous studies have quantified the effects of land-use changes on soil organic carbon (SOC) stocks, few have examined simultaneously the weight of carbon (C) inputs vs. outputs in shaping ... -
Sulfur affects root growth and improves nitrogen recovery and internal efficiency in wheat
(2017)Wheat plants were cultivated in pots with the objective of evaluate the effect of two sulfurrates (+S and -S) on i) shoot growth, S and nitrogen uptake and nitrogen use efficiency(NUE) and ii) root growth and architecture ... -
Variación temporal y espacial de la humedad de suelo y raíces en bosques de ñire bajo uso silvopastoril en Patagonia Sur
(INTA - CIEFAP, 2016-11-09)El objetivo de este trabajo fue medir la variación temporal y espacial de la humedad del suelo y la densidad de raíces finas herbáceas y arbóreas en bosques de Nothofagus antarctica bajo uso silvopastoril. Durante cuatro ... -
Vertical distribution of root biomass and soil carbon stocks in forage cropping systems
(Springer, 2018-02)Background and aims: Forage cropping systems may differentially affect the vertical distribution of roots and soil organic C stock (C-OM). In annual crops sequences (ACS) and perennial pastures (PP), we assessed the ...
