Optimizing nitrogen fertilization for sustainable potato production

Picture copyright Wang et al.

Food security and environmental protection require optimizing crop N fertilization. Scientists Wang et al. reviewed studies on Chinese potato production to determine the optimal N-fertilization rate at a regional scale. The recommended rate improved N use efficiency and agronomic efficiency without sacrificing potato yield. These practices establish a reasonable trade-off between potato production and N-fertilizer management for the development of more sustainable agricultural systems.
