| Abstract: | Best nitrogen management aimed to improve N fertilizer use efficiency and reduce environmental risk is an important component of developing sustainable agriculture, and diagnosis of nitrogen status in both soil and plant is critical to complete best N management. Therefore , on the basis of introduction of characteristics of N diagnosis methods, the significance and the progress of nitrogen diagnosis in potato production were summarized. The key techniques required for N diagn osis in potato production was suggested as well in the paper. |
