There are two kinds of theoretical defects export in the diagnosis and recommendationintegrated system (DRIS): the distribution of nutrient elements ratios with two normaldistribution displays an abnormal distribution of positive skewness; there is a blinddiagnostic area by DRIS on the occasion of the nutrient elements with equal ratios butwithout equal quantity. In the light of the quadratic form theory of multidimensionalnormal distribution and the view of balance of equal probability, the balance diagnosisand recommendation integrated system (BDRIS) was developed in this paper, which issuperior to DRIS and its diagnosis method is unified to critical value diagnosis. Whenthe correlation matrix of nutrient elements R=I(identity matrix), i.e., the effects ofelements antagonism is disregarded, BDRIS will be simplified into the critical valuediagnosis. In addition, the diagnosis program written in SAS language was also providedin this paper.
