Detailed procedures for the reintroduction of endangered freshwater mussel species (order Unionoida) after habitat modification, and the population-level consequences of this, have not been reported for agricultural channels. We reintroduced Pronodularia japanensis (Lea, 1859) into a 70-m-long channel after a concrete lining had been inserted. The ...

Deep placement of urea increases nitrogen use efficiency, rice yields, and farm profitability compared to conventional broadcast urea. However, labor shortages for deep placement pose constraints for wider adoption. Therefore, two types of manual-operated applicators, an “injector-type” (non-continuous operation) and “push-type single row” (continu...

Out-migrating juvenile Chinook Salmon Oncorhynchus tshawytscha in California’s Central Valley lack frequent access to historical off-channel habitats such as floodplains. However, many regions have agricultural floodplains that may provide habitat value to young salmon. To determine the suitability of agricultural floodplain, this study tested whet...

To conserve water resources and guarantee food security, a new technology termed as “wet irrigation” is developed and practiced in rice fields; thus, its impact on radiative forcing derived from nitrous oxide (N2O) and methane (CH4) emissions merits serious attention. Dicyandiamide (DCD), a kind of nitrification inhibitor, is proposed as a viable m...

In the Bengal Delta Plains (BDP) of South Asia, there is an increased report of bioaccumulation of arsenic (As) in rice grains and plants which can ultimately result in health hazards in human population consuming rice as a primary staple food. Five abundant cyanobacteria were isolated from the rice fields of BDP and maintained in vitro. The charac...

Rice plants have a high silica content, which prevents rice straw from being used as a compostable biproduct in the same way as that from wheat and many other crops. The most common post-harvest practice in rice fields in France is to burn and then plough the fields. Flooding harvestedfields during winter may create agronomical and environmental ad...

The intensification of agricultural production in the Mekong Delta has faced serious challenges with respect to increased use of agrochemicals and especially pesticides. The indiscriminate use of pesticide could potentially impact on the long-term food production, environmental and human health in the delta. The aim of this thesis was to investigat...

The use of liquid cattle waste (LCW) as a fertilizer for forage rice is important for material recycling because it can promote biomass production, and reduce the use of chemical fertilizer. Meanwhile, increase in emission of greenhouse gases (GHGs), especially CH4 and N2O would be concerned. We conducted a field study to determine the optimum load...

PurposeThe understanding of soil organic matter (SOM) decomposition to biochar (BC) addition in paddy soil remains limited. This study was to examine the glucose-induced priming effects of paddy soil as affected by aged and/or fresh BCs.Materials and methodsSoil samples were collected from the paddy fields without and with BC applied 1 year before ...

The dissipation and residue of pymetrozine in rice field ecosystem were studied based on a novel and reliable analytical method for pymetrozine in paddy water, soil, rice straw, brown rice, and rice husk. The pymetrozine residues were extracted with acetonitrile and cleaned up by Carb-NH2 SPE cartridge and determined by high-performance liquid chro...
