Abstract
The availability of packaged computer programs for calculating nutrient indices for the DRIS (Diagnosis and Recommendation Integrated System) approach to diagnosing nutrient insufficiencies, excesses and imbalances in plant tissue is reported. A brief outline of the subroutines is given together with details of how to obtain and use the programs. The following crops are covered: maize, soybeans, sorghum, potatoes, wheat, rubber, sugarcane, sunflower, alfalfa.Keywords
