Kariya kan amfani da urea:

1. Urea ya dace da taki mai tushe da kuma ado na sama, wani lokacin kuma a matsayin takin zamani. Ya dace da dukkan albarkatu da dukkan ƙasa. Ana iya amfani dashi azaman taki mai tushe da kuma ado mafi kyau. Ana iya amfani dashi a cikin filayen busassun paddy. A cikin alkaline ko alkaline ƙasa,urea yana da sinadarin hydrolyzed don samar da ammonium nitrogen, kuma yin amfani da farfajiyar zai haifar da ammonia volatilization, saboda haka yakamata ayi amfani da ƙasa mai zurfin rufi.

2. Bayan urea ana fesawa a saman filin paddy, ammonia volatilization bayan hydrolysis shine 10% -30%. A cikin ƙasar alkaline, asarar nitrogen ta gurɓataccen ammoniya shine 12% -60%.
