| Abstract/Contents: | Details two methods for soil testing data analysis. States that "one approach to interpreting soil data is the basic cation saturation ratio method (BCSR), which suggests an ideal 'balance' of calcium (Ca), magnesium (Mg), and potassium (K) on the soil exchange complex...the sufficiency level of available nutrient (SLAN) approach interprets the amount of individual plant-available nutrients in the soil and determines levels where fertilizer applications will likely produce a response and levels where additional nutrient applications are unwarranted." Describes a study in which, "in 27 of the 28 samples, employing the BCSR method would have resulted in needless Ca applications. Moreover, leaf K levels averaged only 0.87% (2.2-2.6% is optimal) in all 28 samples, yet none of these samples called for a K application under the BCSR strategy." Concludes that "the SLAN is a pragmatic method based on research conducted on a wide variety of soil and turfgrass types and should be used as the basis of any fertilization plan." |
