A novel way to establish fertilization recommendations based on agronomic efficiency and a sustainable yield index for rice crops

Abstract A simpler approach for establishing fertilizer recommendations for major crops is urgently required to improve the application efficiency of commercial fertilizers in China. To address this need, we developed a method based on field data drawn from the China Program of the International Pla...
