Types and Uses of Nitrogen Fertilizers for Crop Production
Fertilizers common to crop production in Indiana usually contain nitrogen in one or more of the following forms: nitrate, ammonia, ammonium or urea. Each form has specific properties that determine when, where and how various fertilizer materials can be used.
UAN 28% / UAN 32% - Fertilizer Brokerage
UAN 28% and 32% are both formulations of the same thing, urea-ammonium nitrate, with a 28% nitrogen on one and a 32 % nitrogen on the other. The reason they have both forms is that 32% is how it's produced as a full concentrate and it's used more in southern climates.
Basic calculations for nitrogen fertilizers - Farm Progress
Jan 17, 2023 · To find the amount of actual N per gallon of 28%, simply multiply 28 by 10.6, then divide by 100 to get pounds per gallon of 28%. The math is: 28 x 10.6 / 100 = 2.97. For practical purposes, round it off to 3 pounds of N per gallon, as noted in the table.
Viewing a thread - advantage of 28 or 32 over granular fertilizer
Nov 15, 2008 · Subject: RE: advantage of 28 or 32 over granular fertilizer. MSB is right, N is N, but the availability and loss potential are different between liquid and urea.
