We recently analyzed 16 years of data from a nitrogen rate study at Monmouth, Illinois. The observed best nitrogen rate for corn following corn ranged from 53 to 240 pounds of nitrogen per acre, depending on the year.The predicted best rate of nitrogen based on all 16 years of data was 147 pounds per acre, with a yield of 144 bushels per acre, or slightly more than 1 pound of N per bushel.he pounds of nitrogen per bushel of yield ranged from 0.6 to 2.1, and in only 2 years of the 16 did it fall within the range of 1.1 to 1.2 pounds N per bushel. The variability of these results did not surprise us; we've seen such swings in virtually every study we've conducted.
What is an OPD? OPD is an abbreviation for Overfilling Prevention Device, which is part of new national fire and safety standards designed to make the use of propane even safer. An OPD is a safety feature that prevents small propane cylinders from being overfilled. After January 1, 2003, all propane cylinders 4 pounds to 40 pounds MUST be equipped with an OPD. This standard is required by the National Fire Protection Association and by Oklahoma state law.
That's a common misunderstanding. In a popular slang context, especially in an urban/hip hop setting, OD means to do something to EXTREMES. In other words, to go crazy with something. My friend OD'd on heroin but we kept him walking and made him drink coffee and he was fine, thank god.(clinical) Man, I know you gots a case of Cristal but don't OD! Dat shit is expensive dawg!. (In other words dont binge drink with expensive liquor)(urban/popular)
