| Abstract/Contents: | Presents a study with the following objectives: "1. Compare six different warm-season turfgrasses for nitrate leaching and nitrogen efficiency. 2. Measure root architecture (i.e., depth, density, dynamics) and other root characteristics (i.e., cation exchange capacity, carbohydrate release, microbial association, viability) for the six species. 3. Measure the kinetic parameters of nitrogen uptake for each species. 4. Determine whether root architecture or uptake kinetics explain the difference between species regarding nitrogen uptake. 5. Use a state-of-the-art flow-through nutrient solution culture system to screen germplasm for nitrogen uptake efficiency and to simultaneously determine rooting depth of the genotypes. 6. Determine if root architecture or uptake kinetics are primary determinants of nitrogen use efficiency." States that "to minimize leaching losses, fertilization on newly planted sod should be carefully monitored." Reports that "St. Augustine exhibited the lowest nitrate leaching and Meyer zoysiagrass exhibited the highest nitrate leaching." This five-year study began in 1998. |

| USGA Summary Points: | Nitrate and ammonium leaching from the first nitrogen application to recently sodded turf was high, ranging from 48% to 100% for St. Augustinegrass and zoysiagrass. To minimize leaching losses, fertilization on newly planted sod should be carefully monitored. Considerably less nitrate nitrogen and no ammonium nitrogen leached from subsequent nitrogen applications, probably due to more efficient uptake by the developing root system. There was consistent genotypic difference in nitrate leaching potential. St. Augustine exhibited the lowest nitrate leaching and Meyer zoysiagrass exhibited the highest nitrate leaching. Root architecture was a primary determinant of nitrate leaching and nitrogen use efficiency and highlights the importance of carefully managing both fertility and irrigation when establishing warm-season grasses from sod. |
