Description: | Nitrogen recoveries from fivel levels of urea and ammonium nitrate surface-applied on coastcross pasture, grown on a dark red lotosol (Hapludox), in Sao Carlos, SP, Brazil under tropical altitude climate, were estimated. Significant differences occurred within periods (P<0.05), depending on climatic conditions. Under adequate plant growth conditions, mean N recovery from urea was about 67%, sometimes reaching 80% of that from ammonium nitrate. Recovery of ammonium nitrate varied from 45 to 68% of applied N. |
