Abstract All soils harbor microaggregates, i.e ., compound soil structures smaller than 250 µm. These microaggregates are composed of diverse mineral, organic and biotic materials that bound together during pedogenesis by various physical, chemical biological processes. Consequently, can withstand strong mechanical physicochemical stresses survive slaking in water, allowing them to persist for several decades. Together with the physiochemical heterogeneity their surfaces, three‐dimensional...
Abstract Research gaps in understanding flood changes at the catchment scale caused by forest management, agricultural practices, artificial drainage, and terracing are identified. Potential strategies addressing these proposed, such as complex systems approaches to link processes across time scales, long‐term experiments on physical‐chemical‐biological process interactions, a focus connectivity patterns spatial scales. It is suggested that will stimulate new research coherently addresses...
Pore network geometries of intra‐aggregate pore spaces are great importance for water and ion flux rates controlling C sequestration bioremediation. Advances in non‐invasive three‐dimensional imaging techniques such as synchrotron‐radiation‐based x‐ray microtomography (SR‐μCT), offer excellent opportunities to study the interrelationships between geometry physical processes at spatial resolutions a few micrometers. In this paper we present quantitative pore‐space analyses small scale (∼5 mm...
Assessing root sources of three uncertainties – parameterization soil hydraulic characteristics, boundary conditions, and estimation source/sink terms is a significant challenge in water transport modeling. This study aims to evaluate the uncertainty each widely-used parameter methods affecting plot-scale dynamics. The employs HYDRUS, process-based hydrologic model, incorporate these compare model predictions measured values semiarid Inner Mongolia steppe, China. Soil parameters are...
Roots and the associated soil directly affected by root activity, termed rhizosphere, have both been extensively studied recognized for their crucial role in functioning. The formation of rhizosphere is primarily driven effect roots on shaping physical structure soil, which turn has direct feedbacks interactions between physical, biological chemical processes. As a result, hot spot microbial cycling nutrients turnover organic matter. Despite pivotal controlling processes, we still lack...
Abstract Temporal stability of soil moisture spatial patterns has important implications for optimal and water management effective field monitoring. The aim this study was to investigate the temporal over four plots 105 m × 135 in grid size with different grazing intensities a semi‐arid steppe China. We also examined whether time‐stable location can be identified from causative factors (i.e. soil, vegetation, topography). At each plot, surface (0–6 cm) measured about biweekly 2004 2006...
Abstract. In this paper, we present and analyze a novel global database of soil infiltration measurements, the Soil Water Infiltration Global (SWIG) database. total, 5023 curves were collected across all continents in SWIG These data either provided quality checked by scientists who performed experiments or they digitized from published articles. Data 54 different countries included with major contributions Iran, China, USA. addition to its extensive geographical coverage, cover research...
Spatial inaccessibility of soil organic carbon (SOC) for microbial decay within aggregates is an important stabilization mechanism. However, little known about the stability in semiarid grasslands and their sensitivity to intensive grazing. In this study, a combined approach using chemical physical analytical methods was applied investigate effect grazing exclusion on amount associated protection SOC. Topsoils from continuously grazed (CG) ungrazed sites where excluded 1979 onwards (UG79)...
Environmental contamination with microplastics (MP, 0.1 µm – 5 mm diameter) potentially threatens various soil functions and agricultural production. In this study we evaluated the effects of MP on physical parameters (saturated hydraulic conductivity, water retention repellency) at concentrations (0.5 to 2 % w/w) that have been reported for farmland soils. Polyethylene terephthalate (PET) polystyrene (PS) three sizes ranging between 0.5 3 diameter, were mixed loess topsoil material from an...
The heavily strained water resources in Bengaluru, India, as a result of rapid urban expansion are increasingly at risk overexploitation and pollution due to intensified agriculture practices, such increased nitrogen (N) use irrigation. In recent years, thermal cameras mounted on Unmanned Aerial Vehicles (UAVs) have proven useful detecting crop stress managing However, the these N fertilization subtropics has been understudied. We employed this technology two agricultural field experiments...
