New Nitrogen Application Calculators Built For A Stronger Nutrient Management Plan
Nitrogen plays a critical role in the growth and development of crops. Every season, farmers must consider how much nitrogen they have available in the field, how much they will need to apply, and how much their specific crop type is going to require for a given target yield. The 4Rs of fertilizer management require fertilizers to be applied using the right source and the right rate, at the right time and in the right place. The ‘right rate’ is based on crop requirements and soil tests, but it is also important to ensure your equipment is applying the right rate using simple calculations. It’s not only critical to the sustainable use of nutrients, but it’s vital to productivity and profitability. As farmers make strategic investments in their soil and the growth of their crops, they rely on a greater return.
Understanding the nitrogen in any field has been made easier through our new online calculators—the nitrogen per acre calculator for anhydrous ammonia, the NH₃ acres per tank calculator, and the tractor speed/application rate calculator. These calculators and guides give farmers a better understanding of the nitrogen in their field for a stronger and more profitable nutrient management plan.
Nitrogen Per Acre Calculator For Anhydrous Ammonia
Farmers no longer have to question how much nitrogen they’re applying thanks to our nitrogen per acre calculator. Select the amount of ammonia (NH₃) applied (in liters, kilograms, U.S. gallons or pounds), and the number of acres covered, to calculate how much nitrogen (in pounds) was applied per acre.

NH₃ Acres Per Tank Calculator
How many acres can a farmer cover with the ammonia (NH₃) they have in their tank? Select the tank size, the amount of nutrients in the tank, the nitrogen rate, the application width, and the tractor speed to calculate the number of acres the stock of NH₃ will cover this year.
Try out the free NH₃ Acres Per Tank calculator today.
The NH₃ acres per tank calculator is based on the eKonomics guide below. The chart can be read by selecting the liters of ammonia on hand, the size of the tank, and the number of acres to be fertilized (i.e., if a farmer has 20% in a 1,200-gallon tank, it will cover 13 acres at an 80-pound rate).

Tractor Speed/Application Rate Calculator
Time is often of the essence on the farm. If a farmer only has a small window of time to get their nutrients out in the field, the tractor speed/application rate calculator can help them better understand how long their nitrogen will take to apply. To use this calculator, enter the number of feet traveled, the seconds to travel, and the applicator width to get an accurate speed and acres per hour estimate.
