Effects of amending urea with humic acid and acid sulphate soil in reducing ammonia loss and nitrogen uptake by maize plant
The need to reduce ammonia (NH3) loss from nitrogen based fertilizers such as urea has been recognized. Amending urea with humic acid (HA) and acid sulphate soil could control urea hydrolysis and reduce NH3 volatilization. This approach may contribute to urea-N use efficiency. The objectives of t...
