The rationale behind the technology is the control of nitrogen oxide (NOx) concentrations in the exhaust gases of compression ignition (CI) engines. Fifty percent of the total nitrogen comes from urea, the other 50 percent from ammonium nitrate, resulting in 25 percent NO 3 -, 25 percent NH 4 + and 50 percent urea. Refund Policy, 34 Urea can be fed to milking cows up to a maximum rate of ½ pound (0.22 kg) per cow per day. The Cockroft-Gault formula seems to underestimate GFR. O % = 16 x100/60 = 26.666% Most urea contains about 45% nitrogen, and protein contains 16% nitrogen. However, the cost of nitrogen per lb for urea ($0.67) is actually less than the cost of nitrogen per lb for ammonium nitrate ($0.79).This is because urea has more nitrogen than ammonium nitrate relative to the overall mass. Get answers by asking now.
