In the 50's of the last century, the foreign scholar discovered the Isobutydine diurea has the function of slow release of the nitrogen, thus it has been widely used in flowers and lawn.Besides,it can be used as the forage additive.

Isobutydine diurea is the production of isobutyraldehyde and urea, its molecularfor-mula is (CH3)2CHCH(NHCONH2)2.Its released nitrogen is mainly producedas a res-ult of chemistry hydrolisis, which is different from the urea formaldehyde which depends on the microorganism's decomposition destructive effect and the SCU which depends on the solution's diffusion.

IBDU is very sensitive to water,so the nitrogen's release speed can be controlled by the content of water. Temperature has little effect on theIBDU's hydrolyticaction, which makes it more effective compares to other fertilizers. It is blended with other fertilizers so as to be used for lawn and winter crop.And the functions of being controlled by the content of water and by the low temperatureare the distinguishing features of IBDU.

IBDU is used as the forage additive in place of protein forage so as to make the rum-inants increase their weight and milk.

Below is the specifications for the isobutydine diurea(IBDU)
