| Abstract/Contents: | "The DRIS (Diagnosis and Recommendation Integrated System) approach to interpreting the mineral analysis of turf clippings from home lawns was investigated. Turf clippings were collected from 100 bahiagrass (Paspalum notatum (L.) Flugge) and 182 St. Augustine (Stenotaphrum secundatum (Walt.) Kuntze) home lawns. Visual ratings of turf color and density were made at the time of sample collection. Tissue samples were analyzed for N, P, K, Ca, Mg, Fe, Mn, Zn, and Cu. Conventionally calculated DRIS nutrient ratio norms were reasonably similar in value for the two grasses. Some norms appeared particularly important for turf quality, and, many of these involved micronutrients. A computer program based on IBM-PC BASIC was developed to use the DRIS nutrient ratio means and SD's to calculate DRIS indices for identifying nutrient imbalences and to identify the most limiting nutrients. It appears that DRIS can be a useful tool for evaluating the nutrient status of the turfgrasses studied, and the accumulation of a larger data base for these grasses is warranted to further refine the DRIS analysis. The DRIS program herein has been written in such a way as to facilitate modification when additional data are available." |
