The problem with implementing fish farms in agricultural regions: A trial in a pampean pond highlights potential risks to both human and fish health
(Elsevier, 2020-09)The safety of creating fish farms in agricultural settings was evaluated by growing Piaractus mesopotamicus in a pond, while crops where cultivated in a nearby field under a pesticide application regime typical of the Pampa ... -
Morphological and physiological traits reveal differential salinity tolerance of two contrasting Glandularia cultivars
(Springer, 2020-09)In view of the current, continuous decrease of water availability, the need to explore new mitigation alternatives has given focus to salt-tolerant genotypes. The aim of this work was to study salt tolerance of two ornamental ... -
The impact of interventions in the global land and agri-food sectors on nature’s contributions to people and the UN sustainable development goal
(Wiley, 2020-09-01)Interlocked challenges of climate change, biodiversity loss, and land degradation require transformative interventions in the land management and food production sectors to reduce carbon emissions, strengthen adaptive ... -
Topsoil hardening: effects on soybean root architecture and water extraction patterns
(Springer, 2020-09-01)Topsoil hardening is one of the major causes of poor root growth although its effects on subsoil roots are still not well-known. Our aim was to examine the effects of topsoil hardening on the growth and functioning of ... -
