Abstract

Three sources of N fertilizer (urea, limestone ammonium nitrate (LAN) and ammonium sulphate) showed no consistent significant trends in terms of the dry matter yield and nitrogen or nitrate‐N content of midmar ryegrass. Ammonium sulphate was found to acidify the soil markedly, relative to urea, with LAN showing the least acidifying effect.
