Liebig Review: Essential and Beneficial Elements in the Regulation of Cadmium Uptake and Tolerance in Crop Plants

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Cadmium (Cd2+) contamination in agricultural soils has been reported to pose risks to crop productivity, food safety, and human health. This review synthesizes current knowledge on the mechanisms by which essential (S, Zn, Fe, Mg, K, Ca) and beneficial (Si, Se, rare earth elements) elements mitigate Cd2+ toxicity in plants.

Optimising Sulphur Fertilisation in Ryegrass–White Clover Swards Reduces Leached Nitrate Nitrogen Losses, While Increasing Plant Yield and Nitrogen Off‐Take

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
The inclusion of sulphur at two inorganic nitrogen rates (0 and 150 kg N ha−1) improves plant productivity in a ryegrass–white clover sward and reduces nitrate‐N loss to groundwater in a free‐draining sandy loam soil. ABSTRACT Background Reducing nitrogen (N) losses to water, lessening reliance on inorganic fertiliser and maintaining agricultural ...

An explainable machine learning framework for predicting phosphate oxygen isotopes: Identifying environmental drivers in agricultural watersheds

open access: yesEcological Indicators
Excessive phosphorus inputs from agricultural activities are a major driver of freshwater eutrophication worldwide. Phosphate oxygen isotopes (δ18Op) provide a powerful tracer for identifying phosphate (PO43−) sources and cycling processes at the ...

Experience of using radioactive phosphorus isotope in the treatment of lupus erythematosus

open access: yesKazan medical journal, 1960
Lupus erythematosus is one of the difficult to treat dermatoses. The etiology and pathogenesis of lupus erythematosus remain unclear. Modern medicine for the treatment of this disease does not have specific means. None of the drugs used to treat lupus erythematosus are radical, and none of them prevents relapse.

Impact of Nitrogen Deposition on Carbon and Nitrogen Cycling in Peatlands Under Land‐Use Change

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Increasing nitrogen (N) deposition significantly alters carbon and N dynamics in peatlands by affecting microbial processes, enhancing greenhouse gas emissions and nutrient leaching into adjacent waters. However, how peatland conversion for agriculture and forestry influences the fate of added N under elevated atmospheric deposition remains ...

Integrating Multiple Approaches to Reveal the Spatiotemporal Pattern of Soil Erosion in Mollisol Watershed

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Although numerous prediction methods have been developed, scientific estimation of the spatiotemporal pattern of soil erosion at the watershed scale remains challenging. In this study, fallout radionuclides of 210Pbex and 137Cs were used to estimate average annual soil erosion and deposition in a Mollisol watershed in Northeast China ...

Root Order Dependent Changes in Fine‐Root Substrate and Soil Environment Regulate Soil Organic Nitrogen Fractions Under Acid Rain and Nitrogen Deposition

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Acid rain and nitrogen deposition are important environmental stressors affecting soil nitrogen cycling in subtropical forests, whereas fine‐root decomposition represents a major pathway for soil organic nitrogen (SON) input and transformation.

Carbon‐Fixing Bacterial Network Complexity Mediates Soil Multifunctionality in a Panax notoginseng‐Pinus armandii Agroforestry System

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Autotrophic carbon‐fixing bacteria (CFB) are central contributors to soil carbon sequestration and biogeochemical carbon cycling in agroforestry ecosystems and can act as reliable biological indicators for evaluating agroforestry ecosystem sustainability.

Effects of preservatives and poisons on the elemental and isotopic composition of freshwater particulate organic matter

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Sediment traps, often used in tandem with preservatives or poisons, are widely used for the collection of particulate organic matter (POM), providing insight into the source to sink mechanisms that shape major biogeochemical cycles and sedimentary carbon sequestration.

Arsonic Acid Functional Polymers Enable Stabilization of Iron Oxide Nanoparticles in Aqueous Solution

open access: yesMacromolecular Rapid Communications, EarlyView.
Arsonic acid containing diblock copolymers are developed to incorporate arsonic acid moieties for surface anchoring to IONPs, along with water soluble PEG blocks to impart colloidal stability in aqueous environments. The resulting polymer‐coated IONPs are evaluated for stability in physiological media and cytocompatibility.
