Crop Straw Can Optimize Potassium Fertilization Strategies in Rice Cropping Systems

摘要

Generalized fertilizer recommendations for K in China exist partly because of a lack of local evidence disproving their use, and partly to address limited fertilizer K resources. This research demonstrates how making good use of the nutrient value of crop straw can help optimize fertilizer K application and reduce the reliance on strategies that promote general- ized fertilizer recommendation systems across large areas
