Climate change has been modifying precipitation and temperature in many regions of the world, prompting changes in plant communities. It also affects soil microbial communities, indirectly influencing plant species distribution through plant-soil feedbacks. Here we report an experiment designed to test seed germination responses to global change, addressed through the interaction between increased

Soil cation exchange capacity (CEC) and pH affect the condition of soil. To improve soil capability in sugarcane growing areas, Sugar Research Australia introduced the Six-Easy-Steps Nutrient Guidelines based on CEC and pH of topsoil (0–0.3 m). A three-dimensional digital soil mapping (DSM) framework has been used to predict CEC and pH by fitting equal-area splines to four depth intervals (i.e., topsoil

This article aims to study total phosphorus (TP), available phosphorus (AP) and phosphorus (P) fractions of soil aggregates along an altitude gradient in the sub-alpine region of Southwest, China. We conclude that soil aggregates TP, AP contents are higher in 3980 m and 3347 m; there are no significant differences in soil aggregates TP at any altitude (p> 0.05); the AP and phosphorus activation coefficient

The new farmland created by land consolidation often faces the problems of poor soil structure and low productivity, which cause its potential degradation risk. The Gully Land Consolidation Project (GLCP) significantly increased the quantity of farmland in the Chinese Loess Plateau (LP), but the research on the method of simultaneously improving soil quality, agricultural profit, and utilization efficiency

Conventional tillage disturbs soil structure, increasing the soil’s susceptibility to compaction by machinery traffic in sugarcane fields. In this sense, the adoption of reduced tillage or no-tillage practices associated with traffic control has been proposed to preserve the functionality of soil structure, thus reducing soil compaction and plant growth restrictions. A long-term sugarcane experiment

Nitrogen agronomic efficiency (NAE) is crucial for global food security due to its important role in determining crop yields. However, we do not know whether NAE under nitrogen (N) application changes in the long term, and what controls these temporal dynamics. These knowledge gaps could result in high uncertainty in predicting the increase in global crop yields due to N fertilization in the future

High-severity wildfires may lead to significant impacts on biogeochemical cycling both by burning biomass and by fire legacies. However, the legacy effects of wildfires on multiple soil element cycles across temporal trajectories have rarely been discussed. Here, we evaluated the availability and stability of seven essential soil elements and their stoichiometric ratios, as well as the coupling of

Coastal wetlands sequestering abundant blue carbon in soils are biogeochemical hotspots and critical habitats for benthic animals like invertebrate fiddler crabs. Here, we reveal how crab bioturbation (i.e., burrowing activity) drives the redox geochemistry of ferrous iron (Fe(II)), phosphate (PO43-), and sulfide (S(-II)) under contrasting vegetation types and hydrological conditions. We used in-situ

Areas subjected to frequent winds show severe farmland degradation and air pollution caused by wind erosion and particulate matter emissions. Biological soil crust coverage can inhibit wind erosion. This study used wind tunnels to analyze the wind erosion and particulate matter emissions of algae crusts and moss crusts for different wind speeds and coverage conditions, providing the proportion of particulate

Soil aeration is a critical factor for oxygen limited subsoil processes, as transport by diffusion and advection is restricted by the long distance to the free atmosphere. Oxygen transport into the soil matrix is highly dependent on its connectivity to larger pore channels like earthworm and root colonised biopores. Here we hypothesize that the soil matrix around biopores represents different connectivity

Antibiotics used in animal production are a major source of environmental contamination, since most of them are excreted in manure. However, studies on the impact of antimicrobial effects have focused on humans and livestock, neglecting the environment. The European Union (EU) adopted a strategy to prioritise environmental monitoring and develop tools to make it cost-effective. Our aim was to build

Bacterial communities in the organic leaf litter layer and bulk (mineral and organic) soil are sensitive to environmental change. However, despite close interactions between these communities, the leaf litter layer has historically been studied in isolation from the bulk soil. Whether bacterial response to environmental change is uniform throughout the surface soil remains unclear. Here, we simultaneously

Soil compaction caused by intense machine traffic is a challenge in the sugarcane production system, but its implications can be mitigated by the higher content of soil organic matter and plant root growth provided by conservation management practices (i.e., no-tillage). Thus, we aim to study the impacts of tillage systems on the soil physical attributes, root system and yield of sugarcane propagated

Peatlands contain up to half of terrestrial soil organic carbon (C) while simultaneously emitting the potent greenhouse gas methane (CH4). Global change will alter C biogeochemistry in peatlands, but is hard to predict without a mechanistic understanding of the processes that control anaerobic C cycling. One of the least known anaerobic C cycling pathways in wetland systems is homoacetogenesis, the

The temperature sensitivity (Q10) of soil respiration (Rs) is crucial to assess the carbon (C) budget of terrestrial ecosystems under global warming. The Q10 changes along a climatic gradient as well as its seasonal dynamics remain unclear, and the underlying microbial mechanisms are not well known. Here, the seasonal Q10 of Rs at the northern, middle, and southern sites of a natural temperate mixed

Monitoring experiments of soil air in column show that relative humidity (RH) of air in the soil of the Loess Plateau fluctuates with atmospheric pressure (AP), which is barometric pumping resulting in the vertical movement of soil air and the change of its RH. When AP increases, soil air is compressed and atmospheric air enters the soil, causing RH to decrease. When AP decreases, soil air expands

Stable isotope ratios of soil organic carbon (SOC) are a potentially powerful, integrative tool for analyzing the soil C cycle. However, limited understanding of the mechanisms for C isotope fractionation in soil prevents their widespread application. Soil organic carbon (SOC) is progressively enriched in 13C with age and depth in the soil profile even though CO2 produced during soil respiration is

Forest gaps are an essential driver of litter decomposition in alpine forest ecosystems, but how gap size influences lignin and cellulose degradation in twig litter remains poorly understood. Here, we conducted an 8-year decomposition experiment to assess twig litter decomposition (i.e., mass loss, cellulose and lignin degradation) in four gap size classes in an alpine forest of Southwest China, including

The nondestructive and rapid estimation of soil total carbon (SOC) content with mid-infrared spectroscopy (MIR, 4000 to 400 cm-1) will play a vital role in precision agriculture. However, the benefit derived from the full MIR range is compromised by multicollinearity and noise. Hence, variable selection methods have been developed to reduce the full spectrum to a few variables that contribute the most

Despite growing environmental concerns about perfluoroalkyl and polyfluoroalkyl substances (PFAS) worldwide, the ultra-short-chain PFAS, e.g., trifluoroacetic acid (TFA), have been largely neglected in the context of soil pollution. Given the persistence and increasing occurrence of TFA in the soil environment, the accumulated TFA could impact soil properties and functions. Therefore, we investigated

Soil erosion from traditional hill agriculture is a major concern for agronomic development in the Eastern Himalayas (India). An integrated farming system (IFS: is the combination of multipurpose trees-MPT interspersed with seasonal agricultural crops) may reduce the severity of erosion while ensuring food and nutritional security. The aim of our study was to identify an IFS, resistant to soil erosion

Recent studies have shown that soil particle size analyses using laser diffraction method (LDM) can give compatible results compared with traditional sedimentation based methods, if the clay-silt particle size cutoff is transformed. Additionally, procedures including separation of the sand fraction by wet sieving and running a well dispersed sample of only fractions smaller than sand during laser diffraction

Land application of biosolids as a source of crop fertilizer and soil organic matter can be viewed as a sustainable approach to maintain soil productivity. Field-based experiments were conducted to examine the effects of three municipal biosolids (composted, liquid mesophilic anaerobically digested, and alkaline treated) on soil nitrogen dynamics and corn response, applied over three years in Nova

Mountain peatland ecosystems are unique islands of biodiversity, hosting endangered, vulnerable, and protected plants and animals. In addition, these ecosystems constitute important natural carbon stores. Their stratigraphy can be used to reconstruct the development of these ecosystems as well as the impact of various human activity over millennia. To examine the dynamics of an ombrotrophic peatland

Soil aggregate size distribution (ASD) is a key soil property for quantitative characterization of soil structure. Typically, dry and wet sieving methods are followed to measure mass fractions of soil aggregates under each aggregate size class and their cumulative fractions are used to estimate ASD parameters. In general, available soil ASD databases are small and a comprehensive assessment of existing

Biodiversity-ecosystem function relationships have been widely studied in the field of microorganisms in recent years. The research findings revealed that microorganisms positively influence multiple ecosystem functions in diverse ecosystem types. However, the previous studies have neglected the fact that biodiversity at higher trophic levels is also required in order to maintain ecosystem multifunctionality

The application of organic amendments is an important way to improve soil structure. However, the differences in soil pore properties after adding various organic materials are not fully available, which is important for further selecting the most suitable material for soil improvement. In this study, soil pore structures in a field experiment amended with different organic materials (maize straw,

Soil organic carbon (SOC) originates from a complex mixture of organic materials, and to better understand its role in soil functions, one must characterise its chemical composition. However, current methods, such as solid-state 13C nuclear magnetic resonance (NMR) spectroscopy, are time-consuming and expensive. Diffuse reflectance spectroscopy in the visible and infrared regions (vis–NIR: 350–2500

Phosphorus (P) limitation widely appears in subtropical and tropical regions. Although phosphate-solubilizing bacteria (PSB) can transform soil P fractions and enhance soil P availability, the mechanism regarding the linkage between PSB abundance and soil P fractions transformation were still unknown. In this study, Burkholderia sp. ZP-4, a PSB strain, was inoculated into subtropical bamboo forest

Understanding the changes in microbial communities with increasing plantation age will benefit the maintenance of forest health and productivity and the sustainable development of forest ecosystems. It was not clear whether the microbial communities of pecan plantations would be affected by their age. Based on MiSeq sequencing, we studied the effects of pecan age on microbial communities in rhizosphere

Stress propagation in soil under vehicular traffic can be simulated either analytically based on the laws of continuum mechanics or numerically using finite element (FEM) and discrete element methods (DEM). Soil stress measured by a stress probe may differ from the "true" stress (i.e. the stress without the probe), as probes under- or over-estimate soil stress. No instrument has yet been developed

This study assessed soil Phosphorus (P) fractions and lability according to crops in rotation and crop residue P inputs under long-term no-till (NT) in weathered tropical soils. Two experiments were established in split-plot designs with fall-winter as the main plot and spring as the subplots. In one experiment, sunflower and triticale were grown in Typic Rhodudalf (TR) soil in fall-winter; in the

Plastic-shed vegetable cultivation is characterized by high nitrogen (N) application rates, frequent irrigation and multiple cropping, probably leading to different soil N transformation rates compared to open-field cultivation. However, how continuous cultivation of vegetables under plastic sheds affects soil N transformation rates and associated nitrous oxide (N2O) emissions remains unclear. Here
