Computer program for selection of norms for use in the Diagnosis and Recommendation Integrated System (DRIS)



Computer program for selection of norms for use in the Diagnosis and Recommendation Integrated System (DRIS)



Communications in Soil Science and Plant Analysis 16(4): 339-347



A FORTRAN computer program was written to select the norms and coefficients of variation (CV) for DRIS. The program splits the population into a high and low yielding subpopulation and then calculates the mean, variance and standard deviation for each element and form of expression (ratio and product of each element to all others).
