Nutrient Cycling in Agroecosystems
Methane (CH4) and nitrous oxide (N2O) emissions from rice field in black soil were measured in situ by using static chamber techniques during crop growth season in 2001. The experiment fields were divided into three plots for three different treatments, one with continuous flooded and applying urea (CU), one with continuous flooded and applying slo...

Biodiversity & Conservation
Irrigated rice fields are temporary wetland agro-ecosystems, managed with a variable degree of intensity. A survey was carried out in Sri Lanka to document the overall biodiversity associated with this unique agro-ecosystem, using a combination of sampling techniques to document different groups of fauna and flora. The total number of biota recorde...

Paddy and Water Environment
Pesticides are very important in European rice production. For appropriate environmental protection, it is useful to predict the potential impact of pesticides after application, in paddy fields, in paddy runoff, and in the surrounding water, by calculating predicted environmental concentrations (PECs). In this paper, a joint simulation is describe...

Biology and Fertility of Soils
Wetland rice fields cover 1.46 million km2 globally; the flooded soil of these fields is largely anoxic. While biogeochemistry and microbiology have been studied in detail, the microbial loop and especially the dynamics and function of ciliates are largely unknown. We used anoxic microcosms prepared with soil from an Italian rice field and recorded...

Nutrient Cycling in Agroecosystems
Population size of methanotrophs was enumerated for rhizospheric, bulk and bare soils of a dry land and a flooded rice agroecosystem of Gangetic Plains. Measurements were made for two consecutive years (1997 and 1998). The population size in flooded rice plots was smaller than in the dryland rice plots. In dryland and flooded rice plots during both...

A field trial was conducted to test the insecticidal action of the monolayer surface film ‘Arosurf MSF’ applied by knapsack sprayers, against larvae and pupae of Anopheles arabiensis Patton in a rice irrigation scheme in Western Kenya. Larval and pupal densities and the number of emerging adults were determined by dipping and emergence cages respec...

A longitudinal study, including entomological, parasitological, immunological and clinical data, was carried out in a rice field and a savanna village in Burkina Faso. In this study, the authors followed the evolution of several parasitological parameters in order to compare the level of immunoprotection in children of these two areas. In particula...
