A 2-year study to compare the effect of liquid and solid N-P-K (9:1:4) fertilizers on 'Callie' bermudagrass (Cynodon dactylon var. aridus Harlan et de Wet) production and nutrient uptake was conducted in Central Florida. There was a positive linear relationship between yield and amount of N-P-K fertilizer applied from both sources. Forage N and K concentrations were positively affected and P levels were unaffected by increased fertility levels. Solid fertilizer increased dry matter production and resulted in higher relative uptake efficiencies of the applied N, P, and K than the liquid source. It also maintained higher N concentrations in the forage in some cuttings than the liquid, but neither P nor K concentrations were affected by the fertilizer source. Ammonia volatilization of the urea in the liquid source was probably the major reason for the lower yield, N concentration, and N uptake efficiency with that source. The trend for lower P and K uptake efficiencies by the liquid-treated forage appears to be associated with the lower yields obtained with this source.This material was digitized as part of a cooperative project between the Society for Range Management and the University of Arizona Libraries.The Journal of Range Management archives are made available by the Society for Range Management and the University of Arizona Libraries.
