paddy-farming
Paddy farming is the cultivation of rice in flooded fields, a practice that shapes the plant's unique physiology and root adaptations to waterlogged, low-oxygen soil conditions. Studying this system helps plant scientists understand traits like aerenchyma formation and submergence tolerance, which are critical for improving crop resilience and yield. It also serves as a model for investigating nutrient cycling and microbial interactions in flooded agricultural ecosystems.

Combining biochar and silicon fertilizer in rice paddies improved crop nutrition and significantly reduced antibiotic resistance genes in the soil, offering a practical dual-benefit soil amendment strategy for safer food production.
The combined biochar and silicon treatment produced the lowest abundance of antibiotic resistance genes and mobile genetic elements among all four tested treatments.
Co-application increased soil total nitrogen and total phosphorus, while promoting translocation of silicon and potassium into rice leaves and altering nitrogen and phosphorus distribution within the plant.
The treatment reshaped the bacterial community, reducing key genera (Dinghuibacter and Roseomonas) linked to antibiotic resistance gene spread and nutrient cycling disruption.
