These methods allow\nquantitative evaluation of nutrient imbalances using\nratio-based indices and standardized scores, supporting\nimproved fertilizer use efficiency and crop management\ndecisions. The DRIS method is described in Walworth, J.L. and\nSumner, M.E. (1987) . The\nMDRIS approach is detailed in Beverly, R.B. (1987)\n. The PASS method combining DRIS\nand sufficiency ranges is presented in Baldock, J.O. and\nSchulte, E.E.
