Rice straw decomposition in rice-field soil

Plant and Soil, 1988
Rice straw, buried in a rice-field during the dry season decomposed at a rate of 0.0075 day-1. Seventy five percent of the biomass, 70 percent carbon, 50 percent nitrogen and 30 percent phosphorus remained after 139 days of decomposition. Rice straw decomposition furnished 33% N and 8% P of the total nitrogen and phosphorus provided by man.

Thermophilic methanogens in rice field soil

Environmental Microbiology, 2001
The soil temperature in flooded Italian rice fields is generally lower than 30°C. However, two temperature optima at ≈ 41°C and 50°C were found when soil slurries were anoxically incubated at a temperature range of 10–80°C. The second temperature optimum indicates the presence of thermophilic methanogens in the rice field soil ...

Residues of phosphamidon in rice fields

Environmental Pollution, 1989
Thirty-day-old seedlings of rice plants (IR-20 variety) from the nursery were transplanted into experimental plots and after 52 days were sprayed with phosphamidon (Dimecron 85% EC) at two dose-rates (0.38 kg a.i. ha(-1) and 0.76 kg a.i. ha(-1)). Residues of phosphamidon in the plant, soil and water were analysed by GLC, at various time intervals, and ...

Sulfate-reducing Bacteria in Rice Field Soil and on Rice Roots

Systematic and Applied Microbiology, 1999
Rice plants that were grown in flooded rice soil microcosms were examined for their ability to exhibit sulfate reducing activity. Washed excised rice roots showed sulfate reduction potential when incubated in anaerobic medium indicating the presence of sulfate-reducing bacteria.

Soils and Rice-Fields

2006
Cyanobacteria are an important component of many soils. including the surface crusts that sometimes cover extensive areas in semiarid regions and mine spoil wastes. They are also abundant in many areas which are wet or submerged for part of the year. especially rice-fields. Most soils forms have sheaths or mucilage and this polysaccharide has important

RICE OUTSIDE THE FIELD

Chapter 5 homes in on Blackness and queerness in Thailand during the GI era. American Blackness was new to Thailand, and the identity category called “gay” did not exist until 1965. Both Blackness and gayness were introduced and negotiated in Thailand anew at this time and became something different from what they were in the United States.

Rice roots select for type I methanotrophs in rice field soil

Systematic and Applied Microbiology, 2009
Methanotrophs are an important regulator for reducing methane (CH(4)) emissions from rice field soils. The type I group of the proteobacterial methanotrophs are generally favored at low CH(4) concentration and high O(2) availability, while the type II group lives better under high CH(4) and limiting O(2) conditions.

Chironomids of Italian rice fields

Netherlands Journal of Aquatic Ecology, 1992
Studies on chironomids of Italian rice fields began in 1914, but a comprehensive faunistic picture of Italian rice field chironomids was provided only by COCCHI in 1966. In 1988 and 1989 field research south of Verona (northern Italy) permitted us to confirm the results of COCCHI regardingC.
