Knowing that urea contains 45% N, one hundred lbs. of urea is the crude protein equivalent of how many pounds of soybean meal (44% CP)?

Solution

Urea contains 45% nitrogen by weight ==> 100 pounds of Urea contains 45 pounds of nitrogen

Soybean meal contains 44% nitogen by weight==> 100 pounds of Soybean meal contains 44 pounds of nitrogen

let x pounds of Soybean meal is necessary to get 45 pounds of nitrogen.

100 pounds soybean ==> 44 pounds nitrogen

x     pounds soybean ==> 45 pounds nitrogen

x = (45/44)*100 = 102.27 pounds ~ 102 pounds

hence 100 pounds of Urea equivalent is 102 pounds of Soybean meal.
