Summary: The application of nitrification inhibitors in combination can effectively reduce nitrate content and potential nitrification rate in soils with different pH values. The combination of nitrapyrin and dicyandiamide (CP+DCD) is the most effective in inhibiting soil nitrification and reducing NH3 volatilization in acidic soils. Further research is needed to evaluate the effects of these inhibitors in field conditions.

Summary: The accumulation of microplastics in agricultural soils has been found to have negative effects on soil ecosystem functions, specifically in the volatilization of ammonia (NH3). This study focused on the response mechanism of NH3 volatilization to the occurrence of different sizes of polyethylene terephthalate (PET) microplastics and the role of natural aging. Results showed that both PET10 and PET200 reduced NH3 volatilization in the rice-wheat rotation cycle soil system. PET200 exhibited a more significant reduction in NH3 volatilization and was related to its higher adsorption capacity for NH4+-N and the formation of microaggregates.

Summary: Surface application of ammonium sulfate (AMS) as S source can lead to NH3 volatilization in soils with pH >= 7.0, but with less extent compared to urea. However, in soils with pH < 7.0, AMS volatilizes very little NH3, unlike urea. The N associated with AMS can enhance early biological N fixation by leguminous crops compared to S sources without N, such as polyhalite.

Summary: This study analyzed the seasonal population dynamics of the olive pest B. oleae in a typical olive landscape in Portugal. The results showed that B. oleae is present in all land uses within the landscape, and its dynamics are similar to those in the olive groves. However, the presence of other land uses in the landscape does not lead to an increase in B. oleae abundance within the olive groves. On the contrary, a landscape dominated by olive groves increases the abundance of this pest. Importantly, more diverse landscapes surrounding olive groves can reduce the abundance of the olive fly.

Summary: Biological nitrogen fixation is essential for the development of soybean plants, but management decisions such as pesticide use and timing of Bradyrhizobium sp. inoculation can negatively impact soybean growth and yield. This study evaluates the effects of pre-inoculating soybean seeds with Bradyrhizobium sp. and pesticides seed treatment on biological nitrogen fixation under laboratory, greenhouse, and field conditions. The results show that both pre-inoculation and pesticide seed treatment can reduce the recovery of Bradyrhizobium colonies, ureides concentration, biological nitrogen fixation efficiency, and plant growth. Field experiments also demonstrate that specific pesticides can cause significant yield loss and that inoculation closer to sowing can lead to higher grain weight.

Summary: Farmers sometimes sow soybean in dry soil with the expectation of rain, but this can lead to the seeds remaining in dry soil indefinitely if the rain doesn't come. A study was conducted to assess the survival of inoculated Bradyrhizobium and the physiological quality of soybean seeds sown in dry soil. The results showed that sowing in dry soil negatively affected both the inoculated Bradyrhizobium and the physiological quality of soybean seeds.

Summary: This study examines the effects of different agro-industrial organic wastes on the bacterial community and physicochemical attributes during composting. It was found that animal-derived compost stabilized more carbon and mineralized more organic nitrogen than vegetable-derived compost. Composting enhanced bacterial diversity and reduced the abundance of Firmicutes in animal-derived wastes. Potential biomarkers indicating compost maturity were identified. The source of the waste influenced the final physicochemical attributes, while composting increased microbial community complexity in the order of poultry litter > filter cake > chicken manure. Composted wastes, especially those from animals, appear to have more sustainable attributes for agricultural use.
