Increasing pesticide diversity impairs soil microbial functions

Proceedings of the National Academy of Sciences, Год журнала: 2025, Номер 122(2)

Опубликована: Янв. 9, 2025

Pesticide application is essential for stabilizing agricultural production. However, the effects of increasing pesticide diversity on soil microbial functions remain unclear, particularly under varying nitrogen (N) fertilizer management practices. In this study, we investigated stochasticity microbes and multitrophic networks through amplicon sequencing, assessed community related to carbon (C), N, phosphorus (P), sulfur (S) cycling, characterized dominant bacterial life history strategies via metagenomics along a gradient two N addition levels. Our findings show that higher enriches abundance specialists opportunists capable degrading or resisting pesticides, reducing proportion generalists in absence addition. These shifts can complicate networks. Under increased diversity, selective pressure may drive bacteria streamline their average genome size conserve energy while enhancing C, P, S metabolic capacities, thus accelerating nutrient loss. comparison, was found reduce niche differentiation at mitigating impacts network complexity functional traits associated with ultimately alleviating results reveal contrasting different input scenarios emphasize strategic mitigate ecological use systems.

Ecological Differentiation Among Nitrous Oxide Reducers Enhances Temperature Effects on Riverine N₂O Emissions

Global Change Biology, Год журнала: 2025, Номер 31(2)

ABSTRACT Nitrous oxide (N 2 O) reductase, the sole natural microbial sink for N O, exists in two clades: nosZ I and II. Although previous studies have explored inter‐clade ecological differentiation, intra‐clade variations their implications O dynamics remain understudied. This study investigated both inter‐ differentiation among reducers, drivers influencing these patterns, effects on emissions across continental‐scale river systems. The results showed that II community turnovers were associated with similar key environmental factors, particularly total phosphorus (TP), but variables explained a larger proportion of variation community. influence mean annual temperature (MAT) composition increased more widespread O‐reducing taxa. We identified distinct clusters within each clade reducers observed identical clustering patterns clades. These primarily characterized by MAT regimes, coarse sediment texture as well low TP levels, high abundance producers, MAT‐related constituting predominant proportions. Intra‐clade was crucial predictor flux reduction efficiency. different varying or even contrasting associations dynamics, shared clades exhibited trends. Low‐MAT communities negatively correlated denitrification‐normalized O:(N + ) ratio, whereas high‐MAT positive correlations. pattern likely stems from low‐MAT being better adapted to eutrophic conditions frequent co‐occurrence O‐producing genes. findings advance our understanding distribution functions ecosystems, suggesting warming rivers may decreased efficiency thereby amplify temperature‐driven emissions.

Optimizing cover crop practices as a sustainable solution for global agroecosystem services

Nature Communications, Год журнала: 2024, Номер 15(1)

Опубликована: Дек. 5, 2024

The practice of cover crops has gained popularity as a strategy to improve agricultural sustainability, but its full potential is often limited by environmental trade-offs. Using meta-analytic and data-driven quantifications 2302 observations, we optimized crop practices evaluated their benefits for global agroecosystems. Cover have historically boosted yields, soil carbon storage, stability, also stimulated greenhouse gas emissions. However, combining them with long-term implementation (five years or more) climate-smart (such no-tillage) can enhance these services synergistically. A biculture legume non-legume crops, terminated 25 days before planting the next followed residue mulching, optimal portfolio. Such are projected increase agroecosystem multiservices 1.25%, equivalent annual gains 97.7 million metric tons in production, 21.7 billion dioxide sequestration, 2.41 erosion reduction. By 2100, continued could mitigate climate-related yield losses contribute climate neutrality stabilization, especially harsh underdeveloped areas. These findings underscore promising achieve synergy food security protection. sustainability. In this meta-analysis, authors find that may promote multiple while mitigating 2100.

Soil microbiome interventions for carbon sequestration and climate mitigation

Опубликована: Дек. 18, 2024

Mitigating climate change in soil ecosystems involves complex plant and microbial processes regulating carbon pools flows. Here, we advocate for the use of microbiome interventions to help increase stocks curb greenhouse gas emissions from managed soils. Direct include introduction strains, consortia, phage, transplants, whereas indirect managing conditions or additives modulate community composition its activities. Approaches using microbially catalyzed increasing inputs plants, promoting organic matter (SOM) formation, reducing SOM turnover production diverse gases. Marginal degraded soils may provide greatest opportunities enhancing global stocks. Among many knowledge gaps this field, crucial influencing transformation plant-derived into identity microbes activities impacting transformation. As a critical step forward, encourage broadening current widespread screening potentially beneficial microorganisms encompass functions relevant stimulating Moreover, developing these interventions, must consider potential ecological ramifications uncertainties, such as incurred by homogenous inoculants need site-specificity given extreme variation among habitats. Incentivization implementation at large spatial scales could effectively harness increases stocks, helping mitigate impacts change.
