Abstract
In the first embodiment of the present invention, solution type fertilizers are produced by reacting phosphoric acid with urea-ammonium nitrate solution (35 percent CO(NH2)2, 45 percent NH4 NO3, and 20 percent H2 O), and urea. In the second embodiment, the same solution is produced by reacting phosphoric acid with a urea-ammonium nitrate suspension that contains 36 percent nitrogen, 56 percent urea, and 29 percent ammonium nitrate. The ammonium nitrate portion of the nitrogen solution in said first embodiment reacts with the urea and phosphoric acid to produce urea nitrate (CO{NH}2.HNO3) and ammonium phosphate (probably NH4 H2 PO4). This solution contains rapidly available nitrate nitrogen as well as ammonium type nitrogen that is more slowly available than nitrate nitrogen. Similar results were obtained in said second embodiment when nitrogen solution and urea were reacted with sulfuric acid. The resulting solution contained CO(NH2)2.HNO3 (urea nitrate) and NH4 HSO3 (ammonium bisulfate). The products have a pH that is as low as 1.0 and as high as 4.5. It has been determined that in some soils these low pH materials may have some agronomic advantages as compared to other forms of NP fertilizers with higher pH (4.0 to 8.0). Germination studies show that when wheat seed is mixed with a 27-9-0 grade that is produced by said first embodiment of the instant invention, germination of seed is not adversely affected. This is a principal advantage of the present invention since it has been demonstrated to be a highly desirable procedure to ensure and promote early plant growth. On the other hand, tests show that when urea alone and ammonium phosphate (DAP), with a pH of ≅7, alone, and combinations of these two materials are mixed with the seed, severe germination damage occurs.
