Copper-coated urea for rice production.
Urea is an important fertilizer-N source used in rice production in the world today. However the efficiency of urea is low because it is easily hydrolyzed and lost through ammonia volatilization. Reducing urea solubility and the rate of hydrolysis can increase urea efficiency. Slow release urea...

| Summary: | Urea is an important fertilizer-N source used in
rice production in the world today. However the
efficiency of urea is low because it is easily
hydrolyzed and lost through ammonia
volatilization. Reducing urea solubility and the
rate of hydrolysis can increase urea efficiency. Slow release urea fertilizers can minimize the
loss. Recent field investigations showed that
there are Cu deficiencies occuring in many sites
in the rice growing area in the Muda Irrigation
Scheme, Kedah. |
