How to Use This Calculator

Enter Target Nutrient (lbs/acre) and Product Analysis (%) to determine the gallons-per-acre rate.
Set Product Density (lbs/gal) from the product label (UAN-32 = 11.06 lbs/gal).
Enter Field Size (acres) and Carrier Water (gal/acre) if blending with water in the spray tank.
Set Tank Capacity (gal) to calculate loads required, and Product Price ($/gal) for cost.
Read Product Rate (gal/acre), Solution Concentration (%), Dilution Ratio, and Total Product Used (gal) for application planning.

How the result changes with Product analysis (%)

Target nutrient (lbs/acre): Desired pounds of nutrient per acre (e.g., 120 lbs N).
Product analysis (%): Nutrient percentage of the product (e.g., UAN-32 = 32% N).
Product density (lbs/gal): Weight per gallon (UAN-28 = 10.66, UAN-32 = 11.06, 10-34-0 = 11.65).
Field size (acres): Total acres to be treated.
Carrier water (gal/acre): Gallons of water per acre in spray solution (0 for neat/undiluted).
Tank capacity (gal): Total capacity of the spray/applicator tank.
Product price ($/gal): Cost per gallon of liquid fertilizer.

Product rate (gal/acre): Gallons of liquid fertilizer product needed per acre.
Nutrient per gallon (lbs/gal): Pounds of actual nutrient in each gallon of product.
Total solution (gal/acre): Product plus carrier water per acre.
Solution concentration (%): Product as a percentage of total spray solution.
Dilution ratio (water:product): Parts of water per part of product.
Acres per tank load: Acres covered by one full tank.
Product per tank (gal): Gallons of product to add per tank load.
Water per tank (gal): Gallons of carrier water per tank load.
Tank loads needed: Number of full tank loads for the entire field.
Total product (gal): Total gallons of product for the field.
Cost per acre ($): Product cost per acre.
Cost per lb nutrient ($): Cost per pound of actual nutrient delivered.
Total field cost ($): Total product cost for the entire field.

Identify Input Parameters
4 parameters
Target nutrient (lbs/acre) = 120, Product analysis (%) = 32, Product density (lbs/gal) = 11.06, Field size (acres) = 80 = 7 input(s) provided
Calculate Product rate
33.91 = 33.91
Calculate Nutrient per gallon
Nutrient per gallon = productDensity * (productAnalysis / 100)
3.54 = 3.54
Calculate Total solution
Total solution = galProductPerAcre + carrierVolume
48.91 = 48.91
Calculate Solution concentration
Solution concentration = totalSolutionPerAcre > 0
69.3 = 69.3%
