The paddy soil in the Annamalai University Experimental Farm was analysed for the presence ofAzotobacter spp. in the wet and dry seasons.A. chroococcum, A. indicus, A. lacticogenus, A. agilis, A. beijerinckii andA. vinelandii were the species present, in the same order of population strength. Their populations varied greatly with soil moisture content,

The geochemistry of Thai paddy soils
Geoderma, 2008Abstract This study has determined the elemental composition of uncontaminated Thai paddy soils, and identified whether variations in chemical composition within and between profiles are sedimentological in origin, or due to pedogenic processes. The chemical composition of the paddy soils is highly diverse.

Abstract A series of paddy and non-paddy soil profiles that are developed in chronosequences from approximately 50 to 1000 years of exposure time on fairly uniform marine deposits under nearly identical landscape and climate conditions were sampled from Cixi, Zhejiang Province, China, where rice has been traditionally grown under water submergence ...

Green manures are perhaps the most self-supporting manures in the tropics and are often claimed to be quite as effecient as Ammonium sulphate in rice production. This is of course, not surprising, seeing that they contain nearly 3-4% of nitrogen on dry weight basis, and a carbon/nitrogen ratio of about 10.

Abstract Research on modern paddy field soils in Southeast Asia by Kawaguchi and Kyuma has produced a new classification of ten soil types for growing wet rice. Further study has yielded five fertility classes and a description of the nutritive requirements for good rice yields.

Behavior of technetium in paddy soils
Journal of Radioanalytical and Nuclear Chemistry, 1997In order to understand the chemical form of soluble technetium in paddy soil and its availability to a rice plant, soil incubation and uptake experiments have been carried out using95mTc as a tracer. The chemical form of the soluble Tc was observed by gel chromatography and found not to be pertechnetate, but rather to be associated with soluble organic
