I have three authors with the same family name (Li) but different initials and different co-authors. Do I order them by initials or by coauthors? At the moment, I have them as: Li., C.-F., Yang, J., Zhang, C., Zhang, Z.-S., Zheng, M., Ahmad, S., Cao, C.-G., 2010. Effects of short-term tillage and fertilization on grain yields and soil properties of rice production systems in central China. Journal of Food, Agriculture & Environment 8, 577-584. Li, J.H., Yang, Y.J., Li, B.W., Li, W.J., Wang, G., Knops, J.M.H., 2014. Effects of nitrogen and phosphorus fertilization on soil carbon fractions in alpine meadows on the Qinghai-Tibetan plateau.
