Abstract: Long effect NH4HCO3 was applicated to the main dry land crops i .e.wheat and potato.With normal management,the utility is 0.8 to 9.1 points higher than that of the comm on NH4HCO3.The effective period is double.So the shortage of Nin the late stages of growing season has been com pensated.Dressing same quantity of N,the fertility of long effect NH4HCO3 is much higher than that of urea.Its fertility and utility is even higher than urea when applicated to potato.
