Summary: Efficient use of soil resources, such as nitrogen and phosphorus, can enhance plant resistance and resilience against drought in arid and semi-arid lands. Intercropping legume and non-legumes can improve phosphorus mineralization uptake and plant nutrient status. However, it is still unclear how intercropping systems using desert plant species impact soil-plant phosphorus fractions and their effects on nitrogen and water uptake capacity. This study investigated the impact of intercropping Alhagi sparsifolia and Karelinia caspia on soil-plant phosphorus fractions and soil-plant nutrients. The results suggested that intercropping improved microbe nitrogen-use efficiency, but had limited effects on phosphorus-use efficiency.

Summary: In this study, surface anchoring of black phosphorus quantum dots (BPQDs) and bulk iron-doping in W18O49 nanowires were shown to significantly enhance the photocatalytic activity for N2 fixation into NH3. The reducing ability of photo-generated electrons was enhanced by Fe-doping, while the N2 adsorption/activation was facilitated by surface BPQD anchoring. The synergistic effect of these two approaches remarkably improved the photocatalytic activity of W18O49 nanowires for NH3 production.

Summary: Increasing atmospheric CO2 enhances plant productivity, but nitrogen and phosphorus limitation can constrain plant responses to elevated CO2. In an experiment conducted in the Peak District National Park, grasslands with contrasting levels of phosphorus limitation showed different productivity responses to elevated CO2, with competition between plants and microbes for phosphorus playing a key role.

Summary: This study investigated the effects of phosphorus on nodule nitrogen fixation and nitrogen accumulation in soybeans under sand culture conditions. The results showed that different growth stages of soybean nodules have different requirements for phosphorus supply levels, and the nitrogen supply in different parts of soybean also varies with different growth periods and phosphorus supply concentrations.

Summary: An open-air field experiment showed that elevated CO2 levels significantly affected the abundance and community composition of diazotrophs, while warming had little impact. Diazotrophs in the rhizosphere of wheat were more influenced by elevated CO2, indicating potential implications for agricultural sustainability under future climate scenarios.

Summary: In this article, the authors discuss the role of plant phosphorus acquisition and usage strategies in legume nodulation and biological nitrogen fixation. They also summarize the identified genes or regulatory mechanisms supporting this and synthesize emerging evidence on how microbial strategies and soil management promote legume nodulation and biological nitrogen fixation. Finally, they propose studying legume nodulation and biological nitrogen fixation in a plant-soil-microbe system under low-phosphorus conditions.

Summary: Nitrogen and phosphorus are crucial elements associated with the life history of organisms, and soil microbes play significant roles in nutrient cycling and ecosystem dynamics. This study analyzed microbial C, N, and P concentrations and ratios on a global scale, revealing variations within and across different ecosystems and spatial scales. The scaling exponent of microbial N versus P differed significantly across spatial scales, with soil total P identified as a key contributor to this variation.

Summary: Three PHO2-like genes in Medicago truncatula were characterized for their potential roles in phosphorus and nitrogen metabolism balance and symbiotic nitrogen fixation. Among them, MtPHO2B may play a key role in the balance of phosphorus and nitrogen, while MtPHO2C has limited regulatory effects on phosphorus metabolism. Genetic analysis also revealed a connection between phosphorus allocation, plant growth, and symbiotic nitrogen fixation performance. In conclusion, MtPHO2 genes play important roles in both systemic and localized (nodules) phosphorus metabolism.

Summary: This study investigated the effect of phosphorus on soybean nodule nitrogen fixation. It was found that phosphorus stress induced structural changes in ribosomal proteins, altered protein synthesis profiles, and up-regulated expression of peroxidase. Phosphorus transporter and purple acid phosphatase were also up-regulated to maintain phosphorus balance and nitrogen fixation function in phosphorus-stressed root nodules.

Summary: Healthy soils play a crucial role in planetary survivability, providing not only calories but also other essential functions. However, intensive agriculture is rapidly degrading soils and diminishing their capacity to deliver vital functions, highlighting the need to focus on the multiple functions of soils for long-term human welfare and the survivability of the planet.

Summary: This study investigates the ammonia (NH3) emissions in Australia and assesses the feasibility of reducing NH3 emissions. The results show that the main sources of NH3 emissions in Australia are agricultural activities, with intensive animal and cropping systems contributing the most. Reducing NH3 emissions has significant potential and benefits for society and ecosystem sustainability. Prioritizing the reduction of NH3 emissions in animal and cropping systems is recommended, and integration with current climate policies is necessary.

Summary: The study found that adding litter increased soil CO2 emissions in forests, while removing litter decreased soil CO2 emissions. The negative impact of litter removal on soil CO2 emissions was stronger in tropical forests compared to subtropical and temperate forests. Additionally, litter removal enhanced soil CH4 uptake in tropical and temperate forests, but not in subtropical forests.

Summary: The study found that broomcorn millet has higher yield and increased accumulation of certain nutrients, such as minerals and flavonoids, under elevated CO2 concentration. However, the protein content of the millet decreases under elevated CO2. These findings suggest that broomcorn millet has more desirable nutritional traits and potential for breeding more nutritious plants in the era of climate change.

Summary: Cropland is a major contributor to nitrogen pollution, and reducing this pollution is a challenge due to the decentralized nature of the pollution and the limitations in implementing pollution-reduction measures. By analyzing field observations, we have identified key measures that can significantly reduce nitrogen losses from croplands while improving crop yield and nitrogen use efficiency. Implementing these measures on a global scale could lead to significant benefits in food supply, human health, ecosystems, and climate, with relatively low mitigation costs.

Summary: Understanding the impacts of rising temperature and elevated [CO2] on different crop cultivars is crucial for adapting to climate change. Simulation and pot experiments were conducted to study the growth and yield of two wheat cultivars under elevated [CO2] and 2 degrees C warming. It was found that the early-maturing cultivar was better adapted to elevated [CO2] and rising temperature than the late-maturing one.

Summary: Projected global climate change poses a potential threat to nutrient utilization in agroecosystems. However, the combined effects of elevated [CO2] and canopy warming on nutrient concentrations and translocations in plants are not well understood. This study conducted an open-air field experiment to investigate the impact of elevated [CO2] and canopy air warming on nutrient status during the growing season of winter wheat. The results showed that canopy warming played a more important role in nutrient translocation from belowground to aboveground than elevated [CO2].

Summary: This study develops a generic long-term nitrogen response function for global cereals based on 25 field experiments. The function characterizes the yield impacts, economic benefits, and external costs of changing nitrogen inputs. The study also proposes a new method to assess long-term sustainable nitrogen inputs. The results have important implications for nutrient management practices, policies, and global distribution of cereal production.
