| Abstract/Contents: | "Phosphorus (P) applications to turfgrasses vary with the development stage of the plant. At establishment, it is common to use "starter fertilizers," such as 12N-25P-10K, that are high in P and relatively low in nitrogen (N). Mature grass plants, however, are very efficient users of P. As the root system develops, the amount of P added as fertilizer decreases, unless the soil is very deficient in P. A common analysis for mature turf would be a 20N-2P-15K. The reason for this change is the relative immobility of P in the soil. At the time of establishment, the limited roots system is unable to obtain sufficient P to meet the plant's needs for this element. The P does not readily move in the soil solution to the vicinity of the plant and it must be placed on the surface in close proximity to the developing root. At maturity, the fibrous, multibranched root systems of grasses make them some of the most efficient species at removing P from the soil. A major concern over the use of P fertilizers on turf in recent years has been the possibility of movement of this element into surface waters. Excess P in surface water may result in algal blooms and other environmental problems. While there is some reason for concern where fertilizers are applied on sidewalks and streets in urban areas, P movement from most turf areas is very limited and properly applied fertilizer results in little damage to the environment." |
