nutrient deficiences on fescue
In our experiment, different combinations and rates of Nitrogen, Potassium, and Phosphorus were applied to Festuca arundinaceae, or tall fescue. The goal was to determine which rate and combination would result in the highest rate of shoot growth. Tall fescue is a cool season perennial. It is used in areas with cold winters and mild to hot summers. General uses of tall fescue include as pastureland in some of the southern states and also as lawns, athletic fields and roadsides in certain areas. It is a coarse bunch-type grass that can have rhizomes that spread slowly. Tall fescue can handle soils that are wet, but also has good drought tolerance. Some of this drought tolerance can be attributed to the relatively deep root system it has. Besides drought tolerance, tall fescue tends to have a relatively good tolerance for heat and medium cold tolerance. Shade is tolerated by tall fescue as well. The ideal pH for tall fescue is from 5.5 to 6.5, but will survive under pHs that range from 4.7-8.5 (Beard, 1982-p594). Tall fescue has a medium cultural intensity. Mowing height of two to three inches is relatively high compared to most turf grasses (Collins, 1999-p 76). The high mowing height allows for more

The results of this experiment support this entirely. All plants were fertilized at optimum rates for their desired usage, but only the plants that received nitrogen had any significant yield. All plants seemed to drop in yield on the second week except Urea and super phosphate and where no fertilizer was applied. This shows that the residual fertilizer left in the pots was used up or leached out in the second week of measurements. Earlier in the paper it was stated that phosphorus was essential to new turf development. Although potassium is the second most used nutrient next to nitrogen the plants that received both high amounts of nitrogen and phosphorus had the highest yields. This I believe is due to the fact that new tall fescue tillers were used in the experiment. The Greens Grade fertilizer was the third best in yield but as my graphs show was perhaps the most consistent in yield. This is primarily due to the fact that it released less than half the nitrogen that the Urea did. Greens Grade may have had a lower yield but the plants that received had a healthier color, full tillers, and a more vigorous root system. Phosphate provides the plant with means of holding and transferring energy for metabolic process. The main component of ATP phosphate is most important to the establishment of new turfgrass. Phosphate is also not readily available to plants due to the fact that it has a rapid rate of being tied up in insoluble forms. Urea & super phosphate .19 .2 .17 .21
