Summary: In a 5-year field experiment in the Loess Plateau, China, the effects of long-term fallow tillage on soil microbial community structure and winter wheat yield were evaluated. Results showed that no-tillage and subsoiling tillage methods significantly improved soil moisture and organic carbon contents, as well as the diversity of microbial community. Deep plowing increased the metabolic functional diversity of bacteria and fungi. Both subsoiling tillage and deep plowing increased the yield of winter wheat, with deep plowing having the best effect.

Summary: The relationship between Rhododendron simsii and its soil microbial community under heat stress was investigated in this study. It was found that heat stress altered the physiological characteristics of the plant, soil physicochemical properties, and soil microbial community structure. These changes were correlated with the availability of soil available nitrogen and suggest that the soil microbial community may play a crucial role in plant resistance to heat stress.

Summary: Glyphosate is a widely used broad-spectrum herbicide in agriculture since the 1970s, with increasing levels particularly due to the introduction of glyphosate-resistant crops in the 1990s. Its presence in the environment and potential adverse effects on human health have raised concerns. Bioremediation is suggested as a suitable alternative for treating glyphosate pollution, with microorganisms showing potential for herbicide biodegradation. Further research is needed to understand the mechanisms employed by the microorganisms to counteract glyphosate exposure effects.

Summary: The study found that newborn screening can be expanded using targeted gene sequencing (TGS), which is a feasible and cost-effective method. The TGS assay had a high sensitivity (>99%) and specificity (100%) with a turnaround time of 7 to 10 days and a maximum batch size of 1536 samples. This approach can increase the number of conditions screened and improve the effectiveness of newborn screening programs.

Summary: The application of organic amendment, such as manure, to agricultural soil can lead to the transfer of bacterial pathogens and antibiotic-resistant bacteria. This study investigated the invasion of manure-borne bacteria into amended soil and found that the invasion was still observable 1 month after the soil amendment. Additionally, exposure to the antibiotic sulfamethazine was found to enhance the invasion ability of some manure-borne bacteria.

Summary: The transfer of pesticides from agricultural soils to food and drinking water is a major health concern. This review focuses on the use of multi-elemental compound-specific isotope analysis to study the sources and transformations of pesticides in agricultural soils. Advanced extraction and purification techniques as well as analytical techniques for measuring stable isotope composition of pesticides are discussed. A unique dataset of isotopic compositions of various pesticides and isotope fractionation values for different compounds is reported, providing insights into the mechanisms of pesticide transformation.

Summary: Glyphosate and its metabolite AMPA are frequently detected in European agricultural topsoils. This study found that shrinkage cracks occurring after dry periods could facilitate GLP transport to greater depths where subsoil conditions slow further microbial degradation. The degradation pathway to AMPA dominated, and degradation mainly occurred in Gram+- bacteria.

Summary: Nitrification inhibitors (NIs) have been used in agriculture for over 40 years, but little is known about their activity on different groups of ammonia-oxidizing microorganisms (AOM) and their effects on off-target soil microorganisms. In this study, the researchers compared the efficacy of a novel NI, quinone imine (QI), with established NIs. The results showed that the effectiveness of NIs varied across soils with different pH, and QI significantly affected prokaryotic and fungal diversity. These findings highlight the need for novel NI strategies and the importance of monitoring their impact on off-target soil microorganisms for sustainable use of nitrogen fertilizers and soil ecosystem functioning.

Summary: This study investigated the effects of agronomical doses of beta-triketone herbicides on soil bacterial strains, and found that different strains exhibited varying responses to the herbicides and different molecules had varying inhibitory effects. Molecular docking analysis revealed different binding potentials between the herbicides and bacterial HPPD. The results suggest that these herbicides may impact the HPPD enzymatic activity of non-target microorganisms.

Summary: Soil-borne Neosartorya spp. are highly resilient fungi that can excrete mycotoxins and have great resistance to high temperatures. They easily transfer between soil and crops, posing a threat to horticulture and food production. Despite being a cause of spoilage in fruit produce, juices, and pulps, these fungi can also participate in carbon transformation, sequestration, and plant protection in drought conditions. The taxonomical controversy surrounding Neosartorya spp. and its resemblance to its anamorph leads to uncertain data in research.

Summary: Under agroforestry practices, inter-specific facilitation between tree rows and cultivated alleys occurs when plants increase the growth of their neighbors especially under nutrient limitation. Owing to a coarse root architecture limiting soil inorganic phosphate (Pi) uptake, walnut trees (Juglans spp.) exhibit dependency on soil-borne symbiotic arbuscular mycorrhizal fungi that extend extra-radical hyphae beyond the root Pi depletion zone. To investigate the benefits of mycorrhizal walnuts in alley cropping, we experimentally simulated an agroforestry system in which walnut rootstocks RX1 (J. regia x J. microcarpa) were connected or not by a common mycelial network (CMN) to maize plants grown under two contrasting Pi levels. Mycorrhizal colonization parameters showed that the inoculum reservoir formed by inoculated walnut donor saplings allowed the mycorrhization of maize recipient roots. Relative to non-mycorrhizal plants and whatever the Pi supply, CMN enabled walnut saplings to access maize Pi fertilization residues according to significant increases in biomass, stem diameter, and expression of JrPHT1;1 and JrPHT1;2, two mycorrhiza-inducible phosphate transporter candidates here identified by phylogenic inference of orthologs. In the lowest Pi supply, stem height, leaf Pi concentration, and biomass of RX1 were significantly higher than in non-mycorrhizal controls, showing that mycorrhizal connections between walnut and maize roots alleviated Pi deficiency in the mycorrhizal RX1 donor plant. Under Pi limitation, maize recipient plants also benefited from mycorrhization relative to controls, as inferred from larger stem diameter and height, biomass, leaf number, N content, and Pi concentration. Mycorrhization-induced Pi uptake generated a higher carbon cost for donor walnut plants than for maize plants by increasing walnut plant photosynthesis to provide the AM fungus with carbon assimilate. Here, we show that CMN alleviates Pi deficiency in co-cultivated walnut and maize plants, and may therefore contribute to limit the use of chemical P fertilizers in agroforestry systems.
