Responses to Drought and Flooding

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

Microbial Wastewater Treatment

Microbial Wastewater Treatment

Microbial communities in aquatic ecosystems play a key role in the natural breakdown of contaminants introduced through domestic and industrial effluents. Acting as biological catalysts, these microbes change and mineralize a wide range of organic and inorganic pollutants under different redox conditions.In oxygen-rich surface waters, aerobic heterotrophs lead organic matter breakdown, using oxygen as the terminal electron acceptor to efficiently oxidize substrates to carbon dioxide and water.

Key Elements for Plant Nutrition

Key Elements for Plant Nutrition

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the atmosphere, the...

Adaptations that Reduce Water Loss

Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Plant Breeding and Biotechnology

Plant Breeding and Biotechnology

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Biological Treatment of Effluent and Waste Water

Biological Treatment of Effluent and Waste Water

Biological wastewater treatment relies on the metabolic activity of microorganisms to remove pollutants from sewage. In modern treatment systems, this process is organized into sequential stages that progressively reduce solid material, dissolved organic matter, and microbial contamination. Each stage plays a distinct role in improving water quality and preparing the effluent for safe discharge or reuse.Primary and Secondary TreatmentPrimary treatment is a physical process that removes large...

Agricultural Science
Environmental Science
Water Quality Management

Background:

Nitrogen (N) and phosphorus (P) loss from rice paddy fields is a major concern for water quality in China.
Conventional continuous submergence regime (CSR) leads to significant nutrient export.

Purpose of the Study:

To compare nutrient loss under conventional and improved irrigation-drainage regimes.
To identify cost-effective practices for reducing nutrient loss in rice cultivation.

Main Methods:

Comparison of three irrigation-drainage regimes: continuous submergence regime (CSR), alternating submergence-nonsubmergence regime (ASNR), and zero-drainage irrigation technology (ZDIT).
Quantification of net total N and total P exports via surface field drainage, excluding irrigation input.

Main Results:

Improved regimes (ASNR, ZDIT) showed reduced N and P loss compared to CSR.
Phosphorus export intensity correlated positively with P application rates.
Reduced draining frequency or delayed drainage shifted paddy fields from nutrient sources to sinks.

Conclusions:

Alternating submergence-nonsubmergence regime (ASNR) and zero-drainage irrigation technology (ZDIT) are effective in reducing nutrient loss.
These improved irrigation practices offer economic and environmental benefits by maintaining rice yields at no extra cost.
