Abstract:
     The present invention provides a nitramine humate fertilizer. It is that ammonium nitrate is used as raw material and the external surface of ammonium nitrate is covered with a layer of humic acid. Its ingredient content range (wt%) is: ammonium nitrate is 95-99.5 and humic acid is 0.5-5. The described humic acid also can be nitro-humic acid. The invented nitramine humate is made up by spraying ammonium humate of super-ammonia or ammonium nitro-humate aqueous solution upon the surface of granular ammonium nitrate so as to make it form a layer of humic acid cover film with adsorptive effect on the surface of ammonium nitrate. This fertilizer is good in granular strength, doesn't cake and has slow-acting function, and after having been applied in open field it can reduce loss of nitrogen so as to raise the utilization rate of the fertilizer.
