A Study on the Applicability of HSPF Paddy-RCH for Calculating the Reduction of Agricultural Non-point Pollutants

open access: yes대한환경공학회지, 2020
Objectives:Non-point source pollution (NPS) reduction has been considered as the first priority in South Korea to achieve acceptable water quality. Among many NPS pollutions, agricultural NPS is one of the major NPS contributor due to its vast area ...

Reduced methane emissions from large-scale changes in water management of China’s rice paddies during 1980-2000 [PDF]

open access: yes, 2002
Decreased methane emissions from paddy rice may have contributed to the decline in the rate of increase of global atmospheric methane (CH4) concentration over the last 20 years. In China, midseason paddy drainage, which reduces growing season CH4 fluxes,

Sustainable Development Strategies of Rainfed Paddy Fields in Central Java, Indonesia: A Review

open access: yesCaraka Tani: Journal of Sustainable Agriculture, 2022
Rainfed paddy fields have a great potential to be developed in Indonesia, especially in Central Java. However, water irrigation management, drought stress, pest and disease infestation and low nutrients that affect paddy yield remain the constraints ...

Development of SWAT-PADDY for Simulating Lowland Paddy Fields

open access: yesSustainability, 2016
The consumption of rice, which recently increases globally, leads to requirement for planning sustainable water management for paddy cultivation. In this research, SWAT model was modified to evaluate sustainability of paddy cultivation. Modifications to simulate paddy cultivation are 1) to equip with a new water balance model of impounded fields, 2) to

Macroecology of methane-oxidizing bacteria: the β-diversity of pmoA genotypes in tropical and subtropical rice paddies [PDF]

open access: yes, 2013
Studies addressing microbial biogeography have increased during the past decade, but research on microbial distribution patterns is still in its infancies, and many aspects are only poorly understood. Here, we compared the methanotroph community in paddy

Effect of straw return on soil respiration and NEE of paddy fields under water-saving irrigation. [PDF]

open access: yesPLoS ONE, 2018
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.

Real-Time Measurement of Atmospheric CO2, CH4 and N2O above Rice Fields Based on Laser Heterodyne Radiometers (LHR)

open access: yesAgronomy, 2023
High-precision observations provide an efficient way to calculate greenhouse gas emissions from agricultural fields and their spatial and temporal distributions. Two high-resolution laser heterodyne radiometers (LHRs) were deployed in the suburb of Hefei

THE ECONOMIC VALUE OF PADDY FIELD BASED ON ITS FACULTIES TO SUPPORT LAND PRODUCTIVITY IN LOWOKWARU SUBDISTRICT, MALANG, EAST JAVA

open access: yesAGRISE, 2017
:  Paddy fields commonly possesses intrinsic natural processes and external benefits that support land productivity.  Soil fertility which shown by nutrient contents (Nitrogen, phosporous, potassium and organic matters) gives evidence of the existence of

The Role of Paddy Fields in the Sediment of a Small Agricultural Catchment in the Three Gorges Reservoir Region by the Sediment Fingerprinting Method

open access: yesLand, 2023
Identifying sediment sources is a prerequisite for developing sediment management strategies. Erosion sediment derived from a small agriculture catchment is an important component of sediment inflow in the Three Gorges Reservoir Area.
