Controlled irrigation and drainage (CID) has received attention for improving water quality. Under CID condition, water stress is frequently experienced in two contexts: first drought and then flooding (FDTF) and first flooding and then drought (FFTD). This study aimed to investigate the effects of FDTF and FFTD on nitrogen (N) and phosphorus (P) dynamics in paddy water at different growth stages. The effects of water stress on the migration and transformation of N and P were also investigated…

Impact of Alternate Drought and FloodingStress on Water Use, and Nitrogen and PhosphorusLosses in a Paddy Field
Alternate drought and fl ooding stress has become more prevalent during paddy growth stages as a result of climate change, especially in southern China. This study aims to assess the effect of
Improving Water Productivity and ReducingNutrient Losses by Controlled Irrigationand Drainage in Paddy Fields
Controlled irrigation and drainage (CID) has received considerable attention as a reliable management practice for improving water quality and water productivity in rice production. This study aimed
Response of Vertical Migration and Leaching of Nitrogen in Percolation Water of Paddy Fields under Water-Saving Irrigation and Straw Return Conditions
The use of water-saving irrigation techniques has been encouraged in rice fields in response to irrigation water scarcity. Straw return is an important means of straw reuse. However, the
Interactive Effects of Drought–Flood Abrupt Alternation on Morpho-Agronomic and Nutrient Use Traits in Rice
The frequent occurrence of drought–flood abrupt alternation (DFAA) in Huaibei Plain has shown a great impact on local rice production. Pot experiments were performed in 2016–2018 to investigate the
Ammonia volatilization and nitrogen leaching following top-dressing of urea from water-saving irrigated rice field: impact of two-split surge irrigation
To test whether it is possible to change the nitrogen losses during top-dressing of urea in water-saving irrigated rice field by appropriate irrigation management, two-split surge irrigation (SI) was
Water Quality in Irrigated Paddy Systems
Irrigated paddy rice (Oryza sativa L.) is a staple food for roughly half of the world’s population. Concerns over water quality have arisen in recent decades, particularly in China, which is the
Effect of Irrigation Regimes and Soil Texture on the Potassium Utilization Efficiency of Rice
Understanding the effects of irrigation regime and soil texture on potassium-use efficiency (KUE) of rice (Oryza sativa. L) is essential for improving rice productivity. In this regard, experiments
Tracking the Fate of Fertilizer Nitrogen in a Paddy Rice Field Using Isotope Technology
The aim of this study was to track the fate of nitrogen derived from fertilizer (Ndff) after fertilization. A field in situ experiment covering an entire growing season by using 15N-doubly-labelled
Comparing Three Carbon Substrates with Cow Dung Liquid for Denitrification of Agricultural Drainage Water
Nitrate in agricultural drainage water has been one of the most contributing sources of nitrate contamination of surface water in China. Denitrifying bioreactors are a promising technology to reduce


Potential of Controlled Irrigation and Drainage for Reducing Nitrogen Emission from Rice Paddies in Southern China
The effect of controlled irrigation and drainage (CID) at different growth stages of rice on nitrogen (N) from rice paddy was studied. Submergence at different stages was imposed in specially
Nitrogen and phosphorus loss and optimal drainage time of paddy field under controlled drainage condition
In order to reduce agricultural non-point source pollution and improve water use efficiency, the research on the change in ammonium nitrogen (NH4+-N), nitrate nitrogen (NO3−-N) and total phosphorus
Technical standards of irrigation and drainage management in paddy field of water-saving and pollution-reduction with high yield
Reasonable irrigation and drainage management in paddy field of water-saving and pollution-reduction with high yield is an effective measure to alleviate water shortages, control agricultural
Nitrogen and phosphorus leaching losses from paddy fields with different water and nitrogen managements
While many water-saving rice production techniques have been adopted in China, the environmental effects of these techniques require further investigation. This study aims to assess nitrogen (N) and
Effects of Water-Saving Irrigation and Nitrogen Fertilization on Yield and Yield Components of Rice (Oryza sativa L.)
Abstract The effects of nitrogen (N) application (32, 72 and 112 kg N ha-1 in 2000, and 32, 92 and 152 kg N ha-1 in 2001) and water-saving irrigation and their interaction on grain yield and yield
Effects of alternate wetting and drying irrigation on percolation and nitrogen leaching in paddy fields
The widely adopted alternate wetting and drying (AWD) irrigation for rice production is increasingly needed to quantify the different water outflows and nitrogen leaching losses. We investigated the
