AI Article Synopsis
- A field experiment was conducted to examine nitrogen (N) leakage and runoff in different rice farming systems: rice-duck farming (MRD), conventional farming (MR), and conventional farming with flooding (CK).
- The study found that MRD had a significant reduction in nitrogen concentration, particularly NO3--N, compared to MR, but it was higher than CK, showing mixed results in terms of nitrogen levels.
- Overall, MRD improved nitrogen management by utilizing duck dung, minimizing nitrogen leakage and runoff, leading to less need for chemical fertilizers, and enhancing nitrogen uptake by the rice plants.
Article Abstract
A field experiment was conducted to study the characteristics of paddy field nitrogen (N) leakage and runoff under rice-duck farming (MRD), conventional farming (MR), and conventional farming with flooding (CK). Comparing with that under MR, the paddy field under MRD had a notable decrease of N (especially NO3- -N) concentration in its leaked liquid; but this concentration was tended to be increased, compared with that under CK. After 7-9 days of fertilization, the NH4+ -N and NO3- -N concentrations in paddy field surface water were higher under MRD than under MR. However, owing to the no draining and the higher band, the paddy field under MRD had a notable reduction of drainage, resulting in a marked decrease of N runoff than that under MR. Comparing with MR, the paddy field under MRD had an addition of nitrogen supply from duck dung, a reduction of N leakage and runoff, a lesser application of chemical nitrogen fertilizer, and more nitrogen uptake by rice plant. Both the reduction of N input and that of N output in rice-duck farming system were nearly equal in quantity.

Article Synopsis
- The Qingtian paddy field carp has been domesticated for over 1200 years and has adapted to shallow-water conditions in paddy fields.
- Research involved transcriptome sequencing of the carp's hepatopancreas at different temperatures, revealing 3154 differentially expressed genes linked to various metabolic pathways.
- The study highlights the role of protein processing in the endoplasmic reticulum and the HIF-1 signaling pathway in helping PF-carp maintain cell stability under high temperature and hypoxic conditions.

Article Synopsis
- Enhancing crop productivity is crucial for food security, and biostimulants like zaxinone and its mimics show promise in boosting plant growth and yield.
- Their application was studied to see how they affect soil and rice root microbiota, focusing on bacterial and fungal communities at different growth stages.
- Results indicate that these treatments initially reduced beneficial microbes in the roots but allowed for a recovery in microbial diversity later, highlighting their potential as eco-friendly solutions for agriculture.

Per- and polyfluoroalkyl substances (PFAS) are widely distributed in paddy soils, and their multi-phase partitioning in soil fractions was proved to be strongly interact with soil microbial community composition and functions. Despite this, soil bacterial and fungal metabolic molecular effects on PFAS water-soil interface migration in waterlogged paddy fields still remain unclear. This study integrated soil untargeted metabolomics with microbial amplicon sequencing to elucidate soil metabolic modulations of 15 PFAS interface release.

Under the widespread use backgrounds of fungicides in paddy-dominated basin, the neglect of fungicide environmental fates may aggravate their pollution risks. By integrating field detection with model simulation, we quantified the loss loads and explored the environmental fates of one thiophosphate and five triazole fungicides. Based on the experimental results, we simulated fungicide loss loads with the coefficient of determination of the verification results greater than 0.

Rice-fish farming is an ancient and enduring aquaculture model in China. This study aimed to assess the variations in digestive enzymes, antioxidant properties, glucose metabolism, and nutritional content between reared in paddy fields and ponds. Notably, the levels of amylase and trypsin in from rice paddies were considerably higher compared to those from ponds.
