| Abstract/Contents: | Introduces micronutrient nutrition as being "probably the least understood facet in turfgrass fertilizer management programs... Golf course superintendents irrigating with effluent or salt-affected water, growing-in a new golf course, working with low-CEC and heavily leached soils, or managing highly acidic, calcareous or organic soils are more apt to deal with deficiency or micronutrient imbalances and should have a greater knowledge of the role of micronutrient availability and nutrition." States that "iron (Fe), manganese (Mn), zinc (Z) [(Zn)], copper (Cu), molybdenum (Mo), boron (B), chlorine, (Cl), and nickel (Ni) are also considered essential nutrients for plant growth but are found in much lower concentrations in the plant and thus are termed micronutrients. Their role is equally important, seving as catalysts in a wide array of metabolic functions." Explains how soil and tissue nutrient tests are used to monitor micronutrients. "Soil test recommendations for micronutrients involve a ranking system that is based on expected plant response... A low ranking should be used as a red flag, indicating the need to investigate fertility and management programs more closely. Similarly, a high or excessive ranking for a particular nutrient does not mean that symptoms of toxicity will appear, but that a closer look should be taken at fertility practices." States that "a tissue test may be more helpful to confirm suspected deficiencies and toxicity problems." Suggests methods for obtaining clipping for tissue testing. States that "micronutrient deficiencies may occur because of certain weather conditions or interactions with other micronutrients," and "soil pH probably has the largest impact on micronutrient availability." Suggests that "micronutrients can often be managed proactively with an application or two of a fertilizer containing a complete micronutrient package and by managing soil pH." Explains how using a small test plot can confirm a deficiency of a nutrient and perhaps a need for wider-scale applications. Concludes that "managing micronutrients is not an exact science. Those managing sandy or high-pH soils, salt-affected sites, or who are growing-in a golf course should be familiar with the interactions among micronutrients, the factors that can cause imbalances, and what fertilizer strategies can be used successfully." |
