Abstract/Contents:Presents a study with the following objectives: "1. Extend our current column lysimeter study comparing six different warm-season turfgrasses for NO3 leaching and nitrogen efficiency. 2. Measure root architecture (depth, density, dynamics) and other root characteristics (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 explains the differences between the species. 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. Use genotypes identified in objective five to validate the conclusions regarding rooting architecture vs. uptake kinetics as a primary determinant of nitrogen efficiency." Reports that "a preliminary study to evaluate lysimeter performance demonstrated that nitrate leaching could be reduced during turf establishment by supplementing the fertilizer with sugar, thus stimulating microbial immobilization of the fertilizer." Results also "indicate that growth regulators can be used without increasing the potential for nitrate leaching." This five-year study began in 1998.
