Summary: This study revealed the mechanism of organic acids in enhancing REE tolerance and accumulation in Phytolacca americana, showing that Yttrium stress stimulated the accumulation of oxalate, malate, and citrate, promoting the transport of Y from roots to shoots. Transcriptome analysis indicated that PaNIP1;2 may play a crucial role in the transport of Y-malate complexes within the plant.

Summary: This study found that rhizosheath formation is optimal at an intermediate chia seed mucilage concentration. At low concentrations, there are not enough molecules to support the formation of polymer networks that bind soil particles together, while at high concentrations, the mucilage is too sticky to diffuse far into the soil. Increasing soil moisture promotes rhizosheath formation, but only up to an intermediate volumetric water content of 0.15cm3 cm-3.

Summary: This comprehensive review discusses the multiple roles of flavonoids in mediating plant-microbe interactions, including their synthesis, transport, and exudation in plants, the importance of flavonoids in regulating plant-microbe interactions, and how flavonoids influence the overall community assembly of plant-root microbiomes. The review also highlights potential knowledge gaps in understanding how flavonoids determine the interactions between plants and commensal microbes, advocating for further research in this area for innovative strategies to manipulate plant-microbiome composition.

Summary: This study investigated the correlation between root-adhering soil mass and root hair development, root architecture, and symbiosis with arbuscular mycorrhizal fungi in pearl millet. The genetic control of this trait was analyzed using genome wide association (GWAS) and gene expression studies. The results showed that root exudation mainly regulates rhizosheath formation, which is under complex genetic control in pearl millet.

Summary: In this study, a new approach called laser ablation sample introduction to capillary absorption spectroscopy (LACAS) was developed and demonstrated to study the spatial and temporal heterogeneity of nutrient exchange within the rhizosphere. The LACAS method enabled high spatially resolved mapping of 13C-labeled material within the rhizosphere, providing valuable insights into the distribution of carbon isotopes in plant tissues, rhizosphere, and soil.

Summary: This study investigated the characteristics and temporal dynamics of water-extractable organic matter (WEOM) in rhizosheath and non-rhizosheath soils using spectroscopy. The results showed that rhizosheath soils had higher WEOM content, including more chromophoric, humus-like, and protein-like WEOM, compared to non-rhizosheath soils. Rhizosheath WEOM exhibited lower ammaticity and molecular size, higher fresh microbial contributions, and higher aromaticity and microbial contributions during the middle growth stage. These findings suggest that labile organic compounds are enriched in rhizosheath soils and contribute to the high microbial biomass and activity commonly observed in these soils.

Summary: The interaction between plant roots and microorganisms in the rhizosphere has a significant impact on plant growth and productivity. The components of root exudates are closely associated with the microbial population, particularly plant growth-promoting rhizobacteria (PGPR). However, there is currently insufficient information available to develop effective bio-inoculation/bio-fertilizers for specific crops. It is necessary to identify suitable PGPR candidates to meet the needs of plant growth and yield.

Summary: Water potential plays a crucial role in the functioning of leaves, roots, and microbes, as well as driving water flows in the soil-plant-atmosphere system. However, the measurement of water potential in situ is rare and observations of plant water potential are limited and not widely accessible. This hinders our understanding of biophysical responses to moisture stress and introduces uncertainty into hydrologic and land-surface models. In this paper, the potential gains of continuous and discoverable observations of water potential are outlined, along with improvements in sensor technologies and strategies for data aggregation. Linking representative site-level observations to remote sensing proxies is also highlighted as a novel opportunity. Overall, this paper provides a roadmap for improving our understanding of biophysical processes through continuous and discoverable observations of water potential.

Summary: Livestock, especially in dairy systems, contribute significantly to anthropogenic methane emissions. A novel manure management strategy called biochar-composting has been found to reduce methane by 79% compared to traditional composting. Life-cycle analysis also shows that biochar-composting has a substantially lower global warming potential compared to composting and stockpiling.

Summary: The generalized regression neural network (GRNN) can be used to predict the saturated hydraulic conductivity (K-sat) of soil, and soil texture and electrical conductivity can be used as the influential features in the prediction model. The GRNN model using a small dataset and limited features can provide reliable predictions of K-sat.

Summary: Organic amendments, such as compost and biochar, can improve soil properties, enhance carbon storage, and increase plant biomass. In this field study, the researchers compared the impacts of dairy manure co-composted with biochar, dairy manure compost, and biochar alone on soil properties and processes. The results showed that all three treatments significantly increased soil water holding capacity and total plant biomass. Biochar co-compost and biochar application also resulted in lower greenhouse gas emissions and reduced nutrient leaching compared to compost application alone. These findings suggest that biochar co-composting can optimize organic resource recycling for climate change mitigation and agricultural productivity.

Summary: Finding feasible solutions for sustainable food production is challenging. In this study, we assessed the potential of organic materials such as dairy manure compost and biochar manure co-composts to improve soil ecosystem services and crop productivity. The results showed that biochar co-composts positively influenced soil health, nutrient retention, greenhouse gas emissions, and crop yield. However, external factors like irrigation strategies can constrain the yield response to soil organic amendment. Overall, adding biochar manure co-composts to soil has a positive effect, but careful management is necessary to optimize crop productivity and avoid unintended consequences.

Summary: This study examined the long-term effects of different tillage and cover cropping systems on soil structure and hydraulic properties. The research found that no-till and cover cropping systems improved soil structure in terms of pore size distribution and increased water retention. However, these systems had lower water content at field capacity and lower plant-available water compared to standard-till and no-cover-crop systems. Numerical simulations showed that no-till and cover cropping systems had higher water storage and availability after irrigation. Overall, the study concluded that the long-term practices of no-till and cover cropping systems were beneficial in terms of soil structure changes and marginal improvements in soil water conductivity and storage at the plot scale.

Summary: This study compares subsoil carbon storage and soil organic matter composition in tomato-corn rotations under different carbon and nutrient management in the California Central Valley for 25 years. The results show that subsoil organic carbon content increased in systems with compost and cover crops, while there was no significant increase in systems with mineral fertilizer alone or with mineral fertilizer and cover crops.
