How does liquid nitrogen fertilizer compare with dry as for as volume and weight?

Question

I want 100lbs. of nitrogen per acre. How much liqiuid do I need? Pounds and gallons?

Answer 1

Fertilizer content irregardless of state, is expressed as a number ratio on the label (you can call it percent but that isn't exactly right) in the case of materials that are manufactured for fertilizer use. All other materials, for the most part the bulk organics, are rated in numerous lists, like values for tankage, or worm castings, or used coffee grounds. Of the three numbers present, the first represents nitrogen. Given that fertilizer you need to find out the recommendations for your crop at that rate and use it. It helps to know a bit about your soil and what amendments have been used. Also, just the application of nitrogen may not be in your best interest without knowing how you stand on the other two macros and dozen micro in fertilizer. Solid vs liquid vs gas are important only given size of the area planted and equipment available, as well as organic vs inorganic.

Answer 2

Anhydrous ammonia is 82% nitrogen.  You need 100 lbs of N/acre.

To determine the amount of fertilizer needed divide nutrient needed (100 lbs. N/ac) by nutrient concentration (82 lbs N/100 lbs of anhydrous or .82) in this case

100/0.82 = 121.95 ~ 122 lbs Anhydrous/Acre

This is your fertilizer rate

If I remember correctly, anhydrous is sold, in the US, by the pound (ton usually).
