RELEASE OF SULFUR ON PADDY SOIL CONDITION
The objective of this study was to determine the release of S in paddy soil. The experiment was carried out in the greenhouse which the soil sample was taken from three different sites. The treatment consists of (T0) control, (T1) 0.02 g S pot-1, (T2) 0.04 g S pot-1, (T3) 0.08 g S pot-1, (T4) 0.04 g S pot-1 + rice straw.

Microbial Biomass in Paddy Soil [PDF]
The authors investigated the role of microorganisms in the paddy soil ecosystem and the influence of fertilizer and manure application on the soil “microbial biomass” in paddy soils using Jenkinson’s fumigation method. The results obtained are summarized as follows.

Effect of straw return on soil respiration and NEE of paddy fields under water-saving irrigation. [PDF]
Straw return (SR) and rice water-saving irrigation (WSI) affect the greenhouse gas emission of paddy fields. However, studies on CO2 exchange between paddy fields and the atmosphere with joint regulation of SR and WSI are few.

Continental-Scale Paddy Soil Bacterial Community Structure, Function, and Biotic Interaction
Rice paddy soil-associated microbiota participate in biogeochemical processes that underpin rice yield and soil sustainability, yet continental-scale biogeographic patterns of paddy soil microbiota remain elusive.

Organic and inorganic carbon in paddy soil as evaluated by mid-infrared photoacoustic spectroscopy. [PDF]
Paddy soils are classified as wetlands which play a vital role in climatic change and food production. Soil carbon (C), especially soil organic C (SOC), in paddy soils has been received considerable attention as of recent.

A scheme for soil classification of paddy fields in Japan with special reference to mineral paddy soils [PDF]
Abstract Introduction Paddy (irrigated) rice is the most important single crop in Japan. Nearly half of the total arable lands covering approximately 6.5 million hectares, are devoted to the growing of the rice plant. It is grown mainly on the alluvial plains which are intensively cultivated, and are the most productive soils of the country.

A Rare Allele of ST5 From Wild Rice Enhances Salt Tolerance in Rice
A novel salt‐tolerance gene ST5W, characterized by a unique 36‐bp promoter insertion, is found exclusively in a small subset of Oryza rufipogon and is absent in cultivated rice. Field trials confirm ST5W significantly enhances rice yield across diverse genetic backgrounds under saline conditions.
