A Carboxymethyl Cellulose Hydrogel Switch Enabling pH-Responsive Fertilizer

Abstract The Green Revolution boosted crop yields with synthetic fertilizers, but their high solubility causes environmental pollution and poor synchronization with crop nutrient demands. To address this problem, we developed green intelligent fertilizers (GIF) using a pH-respons...

Grazing intensity regulates cattle movement and forage-use-efficient behavioral patterns through vegetation and abiotic pathways in a temperate meadow steppe

Livestock movement and time allocation are key behavioral processes linking grazing pressure to grassland use efficiency, yet how these behaviors respond to quantified grazing intensity and associated vegetation and abiotic conditions remains insufficiently understood. In this st...

A GacS-mediated regulatory framework coordinates bacterial competition and rhizosphere microbiome remodeling in Pseudomonas fluorescens

Plant growth-promoting Pseudomonas bacteria are promising biocontrol agents whose regulatory and effector genes shape bacterial traits involved in interactions with host plants and soil microorganisms. However, previous research has predominantly examined individual genes or trai...

Flavobacterium xizangense sp. nov. and Flavobacterium erigeronis sp. nov. isolated from the rhizosphere soil of Erigeron canadensis, Tibet, China

Two yellow-pigmented bacterial strains, designated 3-210 T and 3-218 T , were isolated from the rhizosphere soil of Erigeron canadensis collected from Lhalu Wetland, which is located in the northwest corner of Lhasa, Tibet Autonomous Region, China. The two strains were characteri...

Aridity regulates scale-dependent effects of multiple resource additions on productivity stability in Eurasian grasslands

Increasing the supply of multiple limiting resources generally reduces biodiversity and community stability in grasslands. Aridity is known to modify biodiversity-stability relationships, yet it remains unclear whether the effects of multiple resource supply on biodiversity and s...

Assessing plant area index and 3D plant area distribution in wheat canopies from a terrestrial LiDAR system for high-throughput plant phenotyping

This study investigates a new methodology to estimate plant area index ( PAI ) and its spatial distribution from 3D point clouds acquired by a system of 3 LiDARs (2 nadir-viewing and one at 45°) mounted on the Phenomobile Unmanned Ground Vehicle designed for high-throughput pheno...

Toward Iron-Biofortified Rice: Integrating BRUTUS-Family Regulation and Iron Chaperone Biology

Abstract Rice is both a leading model for cereal molecular genetics and one of the world’s most important staple foods, which makes it a decisive crop for iron (Fe) biofortification. However, the breeding goal is not simply to increase total plant Fe or even total grain Fe. For p...

GloSVeT: a global 0.05° monthly mean surface soil and vegetation component temperature dataset (2003–2023)

Current satellite-derived land surface temperature (LST) products represent a mixed radiative signal that integrates soil and vegetation contributions, obscuring the physical mechanisms controlling surface energy partitioning and ecosystem functioning. To overcome this limitation...

Comprehensive Benggang control promotes the recovery of soil organic carbon fractions and carbon sequestration potential

Benggang is a severe collapsing-gully erosion landform in the granite-derived red-soil region of southern China. Although comprehensive Benggang control integrating engineering measures, vegetation restoration, and management has improved the erosion environment and promoted vege...

Divergent Proton-Buffering Processes and Acidification Risks in Permanent and Variable-Charge Soils

Soil acidification threatens agroecosystems, yet the coupled, soil-specific proton-buffering mechanisms in permanent-charge soils (PCSs) and variable-charge soils (VCSs) remain insufficiently quantified. This study systematically investigated surface cation exchange, vacant site...

From Cotton to Wheat–Maize: Farmer Decision-Making and Cropping Structure Transformation in a Smallholder County of China

Adjusting cropping structure is a key way smallholder agriculture adapts to changing labor availability, production costs, mechanization, and agricultural services. Most studies explain such change through macro-level factors—prices, policies, and resource endowments—and pay less...

Household composition and adult-equivalent scales for food consumption expenditures in rural area of China

Purpose Establishing adult-equivalent (AE) scales for rural household food consumption expenditures is crucial for policymakers to set unified benchmarks for living costs in rural China. This study aims to estimate AE scales for food expenditures, providing a standardized tool to...

Reconciling nitrogen fertilization effects on soil nitrification with acidification

Nitrogen (N) fertilization supports nearly half of the global population but disrupts the N cycle. While N addition is assumed to stimulate soil nitrification by increasing substrate supply and nitrifier activity, it may also inhibit nitrification via soil acidification. Resolvin...

Evolution of water clarity across the Beijing-Tianjin-Hebei region over the past four decades (1984–2024): Driven by hydrological expansion and anthropogenic intervention

Given escalating water scarcity and rapid urbanization, characterizing the long-term evolution of surface water environments across the Beijing-Tianjin-Hebei (BTH) region is vital for coordinated regional development. Using Landsat imagery spanning 1984–2024, this study quantifie...

Nitrogen Sources Reshape Microbial Community Assembly and Interaction Networks to Regulate Straw Decomposition and Carbon Release in Cropland Soils of the North China Plain

The decomposition of crop residue is indispensable for carbon (C) cycling in agricultural ecosystems, and nitrogen (N) application has a pronounced effect on this by regulating the C/N ratio and microbial growth strategy. This study investigated how different inorganic and organi...

Spatiotemporal patch identification and multiscale drivers of nonagricultural conversion of cultivated land in the Jianghan Plain

Abstract The nonagricultural conversion of cultivated land (NACCL) poses a major challenge to cultivated land protection and food security in intensive agricultural regions. However, the reliable identification of NACCL in complex agricultural plains remains difficult because cul...
