| Abstract/Contents: | Dicusses soil testing, highlighting sufficiency level of available nutrients (SLAN). Suggests that SLAN "is the best choice for turfgrass managers to use when they look at their soil test results." Explains that "the SLAN approach considers the level of a mineral nutrient in the soil and attempts to predict whether a crop will benefit from fertilizer additions of that mineral nutrient or not." States that "there are different sufficiency levels available depending upon the soil test extractant used, the grass species, and soil characteristics." Suggests that "it is most effective to use the SLAN approach by identifying the critical low levels and then interpreting soil test results by evaluating whether or not a particular nutrient is at a low level that could be inhibiting turfgrass performance." Concludes that "the SLAN approach to soil test interpretation allows [turf managers] to identify nutrient deficiencies based on soil test data. It is a practical method based on experiments looking at turfgrass growth under a range of soil nutrient levels...In addition...knowledge of the outstanding competitive ability of turfgrass in soils with low nutrient availability may allow [turf managers] to reduce fertilizer and pesticide use without sacrificing turfgrass quality." |
