| Abstract/Contents: | The "fertilizer" or "primary" elements essential for plant growth are N, P, and K. Fertilization is most often needed to replentish these three elements. The "secondary" elements are Ca, Mg, and S. These elements along with N, P, and K are termed the "macroelements" because they are needed in greater quantities than the microelements Fe, Mn, Cu, Zn, Mo, B and Cl. Silicon; Si, may also be an essential element for grasses. Nutrient elements can be removed from turfgrass sites by clipping removal, leaching erosion, water runoff, and gaseous loss. Chlorosis, a yellowing of turfgrass, is usually an indication of N or Fe deficiency. Visual assessment should be backed up with soil testing or tissue analysis. When diagnosing turfgrass for the possibility of nutrient problems, it is a good procedure to submit samples from both good as well as bad areas so that results can be compared. Dr. J. B. Jones of the University of Florida has suggested the following sufficiency ranges for nutrient concentrations in turfgrass. N:[2.75-3.50%]. P:[0.30-0.55%]. K:[0.30-0.55%]. K:[1.00-2.50%]. Ca:[0.50-1.25%]. Mg:[0.20-0.60%]. S:[0.20-0.45%]. Fe:[35-100ppm]. Mn:[25-150ppm]. Cu:[5-20ppm]. Zn:[20-55ppm]. B:[10-60ppm]. Mo and Cl: not known. There might not always be visual changes to indicate nutrient deficiencies, but these nutrients are needed. P is beneficial for seedling rooting and vigor. Some research has shown that K applications above that needed for growth may give additional stress tolerance. When turf is deficient in micronutrients, it is usually for one of the following reasons: alkaline soils (pH >7), either native or over-limed; organic soils; leached sandy soils; heavily irrigated areas; and compacted soils (limited root system). Most turf deficiencies have been noted on putting greens. Usually there is no need for a specific micronutrient fertilization. Use tissue or soil analyses to confirm a suspected micronutrient deficiency. Micronutrients are added to soils as impurities and incidental elements in fertilizers, soil amendments, fungicides and pesticides. |
