Enter the desired crop yield and the nitrogen rate into the calculator to determine the nitrogen usage. This calculator helps farmers and agronomists estimate the amount of nitrogen fertilizer needed for a specific crop yield goal.
Nitrogen Usage Formula
The following formula is used to calculate the nitrogen usage.
NU = CY * NR
Variables:
- NU is the nitrogen usage (pounds per acre)
- CY is the desired crop yield (bushels per acre)
- NR is the nitrogen rate (pounds of nitrogen per bushel of crop yield)
To calculate the nitrogen usage, multiply the desired crop yield by the nitrogen rate.
What is Nitrogen Usage?
Nitrogen usage refers to the amount of nitrogen fertilizer that is required to achieve a certain level of crop yield. Nitrogen is a critical nutrient for plant growth and is often applied as fertilizer to enhance crop production. The amount of nitrogen needed can vary depending on the type of crop, soil conditions, and other environmental factors. Proper nitrogen management is essential for maximizing crop yield while minimizing environmental impact.
How to Calculate Nitrogen Usage?
The following steps outline how to calculate the Nitrogen Usage.
- First, determine the desired crop yield (CY) in bushels per acre.
- Next, determine the nitrogen rate (NR) in pounds of nitrogen per bushel of crop yield.
- Next, gather the formula from above = NU = CY * NR.
- Finally, calculate the Nitrogen Usage (NU) in pounds per acre.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
desired crop yield (CY) = 150 bushels per acre
nitrogen rate (NR) = 1.2 pounds per bushel
