| Abstract/Contents: | "The timing of nitrogen fertilization is most critical in the culture of cool season turfgrasses. The interaction between nitrogen nutrition and seasonal influence affects the grass physiology and growth more than the application time of all other essential elements. Root development dictates the performance of turfgrasses; therefore culture practices that stimulate rooting are desirable. Under optimum environment conditions conducive for foliar development, nitrogen availability will stimulate leaf growth at the expense of the roots. However, nitrogen applied when non-structural carbohydrates reserves are naturally increasing will enhance rooting. Therefore, during the fall when temperatures are lowered and CO₂ intake is most positive, nitrogen fertilization will enhance rooting. In early spring when foliar development is naturally occurring, further stimulation with nitrogen will deplete the grass's carbohydrate reserves and root development. At high temperatures, when CO₂ intake is less positive and carbohydrate development is low, nitrogen availability should be limited to cool season turf to lower the plant's respiration and carbohydrate depletion. Fertilization with iron (1-2 lb Fe per acre) at each nitrogen application will not only provide enhanced turf color with less nitrogen, but also condition the turfgrass to improved drought avoidance." |
