Organic chlorine and chloride in submerged paddy soil : a case study in Anhui province, southeast China

, 2004
Efforts to understand the fate of organochlorine compounds in arable soil have concentrated on anthropogenic compounds, in spite of the fact that organochlorine compounds are both produced and mineralized in soil through natural processes.

Ditch‐Buried Straw Return Improves Soil Physical Quality and Crop Biomass in Two Rice–Wheat Paddy Soil Systems

Land Degradation &Development, EarlyView.
ABSTRACT Ditch‐buried straw return (DB) is an innovative practice combining deep tillage and straw incorporation. This study aimed to evaluate its effects on soil physical quality compared to rotary tillage (RT) and identified key constraints to crop in sandy‐loam and clay‐loam paddy soils within rice–wheat systems. Two field experiments were conducted

Effects of Fertilization and Wheat Straw Management on Rice Yield and Greenhouse Gas Emissions in Paddy Fields

Land Degradation &Development, EarlyView.
ABSTRACT Environmental pollution caused by excessive nitrogen fertilization has become increasingly serious, making optimized fertilization and straw management critical for improving agricultural sustainability. This study involved a two‐year field trial with three fertilization strategies: conventional fertilization (CF), 23.50% nitrogen reduction ...

Exploring microbial dynamics, metabolic functions and microbes–metabolites correlation in a millennium paddy soil chronosequence using metabolome and microbiome

Chemical and Biological Technologies in Agriculture
Background Paddy soil is a typical soil type affected by anthropogenic management and factors related to natural soil formation. The evolution from mudflats to typical paddy soils can significantly affect the soil microecology.

Anaerobic Arsenite Oxidation by an Autotrophic Arsenite-Oxidizing Bacterium from an Arsenic-Contaminated Paddy Soil

, 2015
Microbe-mediated arsenic (As) redox reactions play an important role in the biogeochemical cycling of As. Reduction of arsenate [As­(V)] generally leads to As mobilization in paddy soils and increased As availability to rice plants, whereas oxidation of ...

Rice straw amendment ameliorates harmful effect of salinity and increases nitrogen availability in a saline paddy soil

Journal of the Saudi Society of Agricultural Sciences, 2018
High concentrations of salt (NaCl) in soils reduce plant growth and have enormous influence on nitrogen dynamics in the soil solution. However, addition of rice straw is expected to mitigate the effect of salinity on nitrogen cycling, therefore ...

Trade‐Offs and Synergies in Cultivated Land Multifunctionality and Zoning Management in the Dongting Lake Region: A Multiscale Analysis

Land Degradation &Development, EarlyView.
ABSTRACT Understanding the multiscale patterns and interactions of cultivated land multifunctionality is important for conservation, governance, and agricultural spatial optimization in the Dongting Lake region. Using 2020 data, we evaluated economic production (EPF), social security (SSF), landscape‐based recreation (LRF), and ecological maintenance ...
