Biological nitrogen fixation contributes greatly to the sustainability of agroecosystems. However, more information is needed about the impact that agricultural intensification, a frequent practice nowadays, would have on diazotrophic communities associated with plants. This work addresses the influence of intensifying rice cropping systems on the abundance, diversity, and structure of diazotrophic communities associated with rice roots (rhizospheric and endophytic bacteria) from a field experiment. Three different rice rotation systems (rice-pasture, rice-soybean, and continuous rice) at two crop growth stages (TBF: tillering before flooding and FF: flowering-flooded) were studied. The results showed that the rhizospheric soils had the greater nifH gene abundance, and the abundance and diversity of rhizospheric and endophytic diazotrophic communities significantly increased at the FF stage. Conversely, nifH abundance in bulk soils remained unaltered. Phylogenetically and metabolically diverse diazotrophic communities were found to be associated with rice roots from the different crop stages and rotations. © The Author(s) under exclusive licence to Society for Environmental Sustainability 2023 |

Two studies were conducted to evaluate the influence of packaging and production system (PS) on retail display life color (L*, a*, and b*), fatty acid profile (% of total fatty acids), lipid oxidation (thiobarbituric acid reactive substances; mg malondialdehyde/kg of muscle), vitamin E content (μg/g of muscle), and odor (trained panelists) during storage of LM. Four (or 3) different packaging treatments were applied to LM from steers fattened on grazing systems (Uruguayan) or on high-concentrate diets (U.S.). From fabrication to application of treatments, Uruguayan LM were vacuum packaged for air shipment and U.S. LM were also vacuum packaged and kept in a cooler until Uruguayan samples arrived. Treatments were applied 7 d after slaughter. In Exp. 1, treatments were vacuum packaging (VP), lowoxygen (O2) modified atmosphere packaging (MAP) with nitrogen (N2) and carbon dioxide (MAP/CO2), low-O2 MAP with N2 plus CO2 and carbon monoxide (MAP/CO), and VP plus an application of peroxyacetic acid (VP/PAA). In Exp. 2 block 1, treatments were VP, MAP/CO, and VP with ethyl-N-lauroyl-l-arginate HCl incorporated into the film as an antimicrobial agent (VP/AM). In Exp. 2 block 2, treatments were VP, MAP/CO2, MAP/CO, and VP/AM. After 35 d storage, steaks were evaluated during simulated retail display for up to 6 d. In Exp. 1, Uruguayan steaks under MAP/CO had greater (P < 0.05) a* values than VP/PAA and MAP/CO2 on d 6 of display. For U.S. beef, the MAP/CO had the reddest lean color (P < 0.05) compared with the other 3 packaging treatments on d 6 of display in Exp. 1. Packaging × PS × time interaction was significant (P < 0.05) in Exp. 1. In Exp. 2, MAP/CO in Uruguayan steaks also had the greatest a* values on d 6 of display, but no differences (P > 0.05) were detected among both VP and MAP/CO in U.S. steaks at this time. No significant (P > 0.05) packaging × PS × time interaction was observed in Exp. 2. Only PS (both xperiments) and time (Exp. 1) affected (P < 0.05) L* values. In both experiments, U.S. steaks had greater (P < 0.05) L* values than Uruguayan steaks. Vitamin E content in Uruguayan steaks was greater (P < 0.05) than in U.S. steaks. Packaging × PS, PS × time, and packaging × PS × time interactions were not significant (P > 0.05) for any of the fatty acids. Beef from Uruguayan had lower (P < 0.05) SFA and MUFA and greater (P < 0.05) PUFA and n-6 and n-3 fatty acid percentages than U.S. beef. Complexity of fresh meat postmortem chemistry warrants a more comprehensive approach to maximize shelf life.
