Summary: Plant growth is associated with values of collinear traits from the leaf economics spectrum. Environmental variation and differences in community composition may affect the contributions of these traits to plant production. We tested the effects of interannual variation in precipitation and differences in grassland community composition on trait-based predictions of aboveground net primary production (ANP). Results showed that mean trends could be predicted using community-scale values of leaf dry matter content (LDMC), but precipitation and community effects influenced the production-trait relationships.

Summary: This study investigates the impact of early-season plant-to-plant spatial uniformity on soybean yield at reduced seeding rates. It suggests new metrics to characterize plant-to-plant spacing and identifies the best metrics correlating with soybean yield. The findings emphasize the importance of spatial uniformity and its interaction with yield environments and plant densities in soybean production.

Summary: This study measured leaf nitrogen content of 1,844 plant species from 22 natural communities and investigated the effect of different scaling-up methods on the spatial variation of leaf nitrogen in plant communities. The results showed that different scaling-up methods influenced the spatial variation of leaf nitrogen, with N-SAM and N-CWM decreasing with increasing precipitation, and NPLA-CWM showing the opposite trend. Additionally, N-SAM overestimated leaf nitrogen in dry or cold environments and underestimated it in wet or warm environments compared to N-CWM.

Summary: With the developments in nanotechnology, the combination of innovative photonic designs and functional materials provides a unique approach to acquire, share, and respond to information. A study found that depositing a 30 nm-thick palladium nanofilm on a terahertz metasurface chip allows for the tracking of gas and matter interactions, including gas adsorption, hydrogenation, metal phase changes, and water-forming reactions. Combinatorial analyses by simulation and experimental measurements demonstrate the significant impact of the nanostructures on light-matter interactions and propose methods for tracking unknown stages of water-forming reactions.

Summary: Plant water content is crucial for plant health, and timely detection of water needs is important for irrigation strategies. This study developed a cost-effective and portable system using electrical impedance spectroscopy (EIS) to provide reliable information about plant water status. The results demonstrate that the system can track changes in water content of plant leaves and provide insights into leaf tissue structure.

Summary: Industrial solid waste is the solid waste produced in industrial production activities, which may cause environmental pollution if not treated and released correctly. This study proposes a method for the quantitative analysis of harmful components in industrial solid waste using terahertz spectroscopy combined with chemometrics. Compared with the conventional Raman method, the terahertz method shows higher accuracy in concentration analysis. In addition, the method is also effective for the quantitative analysis of mixtures.
