Improved rice yield and macronutrient uptake through the optimization of organic fertilizer rates in the rice-crayfish co-culture system.
The rice-crayfish coculture system (RC) is an integrated planting-breeding model that balances ecological and economic benefits. The combined application of organic and chemical fertilizers is effective for crop production, but the optimal organic fertilizer rate in RC remains unclear. In 2024 and 2025, five organic fe...
