Fertilizer, Lime and Seeding

These calculators turn a target into a product amount. Set a corn nitrogen rate, convert a nutrient rate into pounds of fertilizer, size a lawn application from N-P-K, apply a soil-test lime recommendation and find the seeds and pounds per acre for a plant stand.

Tools in this group

• Corn Nitrogen Rate Calculator (Yield Goal Method) — Enter your yield goal, previous crop and credits to get a nitrogen rate in lb N per acre, then the pounds or gallons of urea, ammonia or UAN and the cost.
• Fertilizer Calculator (NPK) — Type the nutrient rate you need and pick the product to get pounds (or kg) of fertilizer per acre, bags and cost.
• Lawn Fertilizer Calculator — Enter your lawn size, the nitrogen rate and the fertilizer's N-P-K to get how much product to spread and how many bags to buy.
• Lime Calculator (Lime per Acre) — Enter the soil-test lime recommendation and your product's quality to get the rate per acre or per 1,000 sq ft and the total.
• Seeding Rate Calculator — Enter the plant stand you want, germination and seed size to get seeds and pounds per acre, or work out plant population from spacing.
