Abstract
In two trials conducted during 1971 the effects on total and seasonal production of grass dry matter and the crops' nitrogen recovery from a single spring application of a sulphur‐coated urea or urea formaldehyde were compared with an equal amount of nitrogen applied in five dressings of urea or ammonium nitrate.Ammonium nitrate gave higher dry matter yields and nitrogen recovery than urea. Sulphur‐coated urea as a single application gave results similar or superior to split applications of ammonium nitrate, but seasonal distribution of these were slightly different. Urea formaldehyde proved inferior, in the parameters measured, to the other fertilisers.Keywords
