| Abstract/Contents: | "Calcium chloride (CaCl2) and ammonium thiosulfate (ATS) have demonstrated an ability to inhibit urea hydrolysis and NH3 volatilization. The objective of this experiment was to determine the effect of rainfall and soil drying on the ability of CaCl2 and ATS to increase bermudagrass nitrogen (N) uptake from the surface-applied urea.Urea fertilizer, labeled with 15N and amended with CaCl2 or ATS, was surface-applied to bermudagrass sod-cores from Ships clay (C) and Lufkin fine sandy loam (fsl) soils. Bermudagrass sod-cores were subjected to either low or high rainfall regimes beginning seven days after fertilizer applications. After one month, bermudagrass was harvested and analyzed for total N and 15N content, Calcium chloride significantly increased bermudagrass N use efficiency (NUE) of surface applied urea by 33 to 47% on the Lufkin fsl, but has little effect on the Ships c. Apparently, CaCl2 is most effective of coarse textured soil with low cation exchange capacity (CEC). Stimulated rainfall had no effect on yield or NUE for the lafkin fsl, but for the Ships c, bermudagrass yield and NUE generally increased with rainfall. The absence of differences among N treatments on the Ships c suggests that urea hydrolysis and N loss were limited due the combined effects of high soil CEC and rapid daily drying of the sod-core surfaces. Ammonium thiosulfate did not affect bermudagrass yield or NUE for either soil or rainfall regime." |
