Summary: The study found that nitrogen fertilization increased fungal biomass, especially in the northern region, mainly by promoting root-associated Ascomycetes, but this response was moderated by thinning. Fungal biomass was positively correlated with carbon stocks in the organic topsoil. However, ectomycorrhizal Cortinarius species were reduced in abundance by fertilization and correlated negatively with carbon stocks.

Summary: This study analyzed the effects of Italian ryegrass cultivar and usage methods on soybean growth and yield. The results showed that using Italian ryegrass as green manure could increase soybean yield, while using it as forage could bring additional harvested matter to the rotational system.

Summary: The study revealed that under extra nitrogen input, plant species relative abundance is influenced by both light and non-nitrogen nutrient acquisition capacities. Taller Stipa purpurea increases in relative abundance by improving light acquisition, while shorter Carex stenophylloides excels in phosphorus acquisition to elevate its relative abundance under nitrogen enrichment.

Summary: This study addresses the impact of anthropogenic nitrogen deposition on soil respiration in a Tibetan alpine steppe. The results indicate that above-/below-ground biodiversity loss, changes in plant community composition, and plant functional diversity play significant roles in regulating autotrophic and heterotrophic respiration in response to nitrogen enrichment.

Summary: The study found that under elevated CO2 concentration, proper nitrogen application can increase wheat yield, but excessive temperature rise may decrease this benefit. Nitrogen significantly influences the response to CO2, while CO2 enrichment and temperature increase can reduce crop evapotranspiration.

Summary: This study conducted a meta-regression analysis on wheat, rice, soybean, and maize to examine the simultaneous effects of increasing carbon dioxide concentrations and warming temperatures on seed yields. The results showed that seed yield had a positive linear response to increasing carbon dioxide concentrations, while it had a negative linear response to warming temperatures. Additionally, considering potential future climate scenarios, carbon dioxide fertilization effects on seed yield are likely to be greatly reduced or completely negated in major crops.

Summary: California ground squirrels cause significant economic damage to California rangelands, particularly in terms of forage loss. However, our understanding of these economic losses is limited and public opinion towards ground squirrel control is not supportive. This study found that ground squirrel abundance and precipitation have significant effects on standing crop biomass, while livestock grazing intensity does not.

Summary: The study demonstrates that no tillage and residue mulching can increase soil organic carbon and nutrient content, playing a beneficial role in black soil conservation; no tillage with 60% residue mulching significantly increases the alpha diversity of rhizosphere soil bacteria and alters the composition of the bacterial community.

Summary: The study aims to adapt the superposition principle to non-stationary ground-source heat pump operations, using an advanced response model to evaluate outlet temperature signals under different operating conditions and considering transitions with a combination of linear functions and a scaled correction function. Through eight synthetic validation studies, the method is shown to reproduce reference numerical results accurately and efficiently for simulating ground heat exchangers with time-variant flow rates.

Summary: This paper proposed a ground point fitting method based on UAV SfM point cloud to estimate the height of winter wheat. By designing a canopy slice filter and fitting missing ground points, the extraction of ground points was successfully optimized and terrain undulations were effectively simulated to improve accuracy.

Summary: The study evaluated the use of Time-to-Positivity (TTP) as a rapid method for estimating Salmonella contamination levels in ground beef, with high sensitivity (100%) and specificity (83% and 93% for two detection methods) for samples with a TTP4 and false negative rates of 0%.

Summary: This article presents the results of geophysical studies on the technical condition of two railroad bridges and their ground foundations in permafrost areas. The passive seismic standing wave method can determine the frequencies and shapes of the bridge's natural vibrations, while electrotomography of the soil foundation identifies thawed soil zones. These methods provide an effective means for assessing the technical condition and potential stability loss of the bridges.

Summary: The study provides an overview of the design methods and application of self-standing retaining walls in Japan, highlighting the variations in calculated embedded length depending on different analysis methods. However, there is a lack of case studies on the influence of design methods and ground conditions on evaluation results.
