Abstract
The efficiency of various S-coated urea and KCl compounds applied to stargrass growing on an Ultisol under humid tropical conditions was determined. Applying N as urea in six applications yearly or in one application of S-coated urea compounds TV 1415 and 1255 resulted in higher recovery of fert ilizer N compared to urea in one application. Applying K as KCl in six applications yearly resulted in higher recovery of fertilizer K in the forage than when applied in one application. The various S-coated KCl compounds did not result in higher recovery of fertilizer K than did KCl in one application.
