Summary: The study found that in some cases, anaerobically mineralized nitrogen within large macroaggregates may be a better indicator of soil health than in bulk soil; however, due to the more time-consuming nature of determining anaerobically mineralized nitrogen within large macroaggregates, it is recommended to use anaerobically mineralized nitrogen in bulk soil as a variable for monitoring soil health.

Summary: The study investigates the impact of different fertilization practices on soil aggregate stability and aggregate-associated carbon in alkaline soil. Results show that manure application improves soil physicochemical properties and enhances the stability of aggregates and aggregate-associated carbon, while high pH restricts their stability. Strategies to improve alkaline soil and increase soil carbon stocks may prioritize manure or fertilizer application to reduce soil acidity.

Summary: This study assessed the long-term effects of biochar on soil organic carbon (SOC) accumulation through an 8-year field experiment. The results showed that the application of 3% and 5% biochar increased the content of macroaggregates, decreased the content of microaggregates, and significantly improved the stability of soil aggregates. Additionally, the application of 3% and 5% biochar had significant effects on SOC accumulation in all aggregate fractions, while the application of 1% biochar did not. These findings suggest that long-term application of 3% and 5% biochar is beneficial for enhancing SOC accumulation in clay loam soil and improving the stability of the soil carbon pool.

Summary: Organic crop production is a growing sector in agriculture, but transitioning from conventional to organic cropping systems is challenging for growers. This study evaluated the impact of different perennial and annual cropping systems on soil health during a three-year organic transition period in Minnesota. The results showed that IWG and IWGAlfalfa systems had positive effects on root biomass and soil aggregates, while SoyCorn systems performed the poorest. Other soil health variables had site-specific responses, and IWGAlfalfa increased microbial biomass at one site. The findings suggest that IWG and IWGAlfalfa could contribute to long-term soil health in subsequent organic crops, but more time may be needed for other important soil health parameters.

Summary: Common mycorrhizal networks are believed to facilitate nutrient transfer between plants, and this experiment showed that under drought conditions, these networks can significantly increase the shoot biomass of Trifolium subterraneum when grown near Panicum clandestinum. The bacterial community profiles in the rhizospheres of both plants were similar, but drought stress altered the relative abundance of certain bacteria, especially when connected by a common mycorrhizal network. Drought stress also affected the abundance of N-cycling genes differently under the two plant species.

Summary: Rainfall's spatiotemporal variability plays a key role in catchment runoff and flood response. This study assesses the sensitivity of runoff and flooded areas to rainfall movement in the Kan catchment (Iran). The results show that rainfall movement affects the runoff response, with higher velocities resulting in higher peaks and faster onsets of runoff. The direction of movement also plays a role, with storms moving along the average direction of the stream resulting in higher peaks and flooded areas. The influence of rainfall movement is also modulated by hyetograph structure and location within the drainage network.

Summary: Microbial inoculants containing arbuscular mycorrhizal (AM) fungi have the potential to increase the sustainability of food production systems. However, their use is limited by inconsistent product efficacy and lack of consumer confidence. To address this issue, a framework for assessing the quality and reliability of AM inoculants is proposed, including basic quality criteria and standardized bioassays.

Summary: Microorganisms drive important soil processes and ecosystem functioning, but environmental changes can alter soil microbial community and affect the decomposition and storage of SOC. In a grassland experiment, we found that fertilization with nitrogen and phosphorus had divergent effects on the taxonomic and functional attributes of soil microbes, with a greater impact on bacteria and fungi than on SOC degradation genes. SOC concentration was negatively correlated with the abundance of SOC degradation genes, indicating that fertilization could stimulate SOC decomposition by modifying the soil microbial community. Our results suggest that soil total P plays a pivotal role in shaping the microbial community and that the abundance of SOC degradation genes has a stronger influence on SOC concentrations than taxonomic attributes. Quantifying the abundance of SOC degradation genes can provide a more effective understanding of SOC decomposition and prediction of soil function shifts in grasslands. Based on the important role of microbial community in regulating SOC decomposition and maintaining high SOC concentrations, we recommend protecting alpine meadows from mineral fertilizers, especially P alone fertilization.

Summary: The priming effects of soil organic matter (SOM) decomposition influenced by fertilizers affect carbon balance and nutrient release. Nitrogen (N) and phosphorus (P) limitation in Tibetan meadows can retard SOM decomposition, but N and P fertilization can alleviate this limitation and induce priming effects. P fertilization has the highest priming effect and the lowest SOM storage.

Summary: Excessive fertilizer usage can limit soil biological processes in pastures, especially those related to arbuscular mycorrhizal (AM) fungi. This study examined the effect of fertilizers with different P solubility on AM fungal colonization in the roots of two common pasture plants. The results showed that both fertilizers reduced the proportion and length of roots colonized by AM fungi, but the reduction was more pronounced in subterranean clover compared to annual ryegrass. The diversity indices of AM fungi were also altered, with the chemical fertilizer having a greater negative effect on the diversity of annual ryegrass roots. The findings suggest that different P fertilizers can influence the efficacy of fertilization and dominant plant species in grasslands.
