Crop Farming Calculators
Field-scale arithmetic for crop growers: seeding rate from thousand kernel weight, seed spacing and plant population, sprayer calibration in gallons per acre, acre-inch irrigation, grain bin bushels, bushels to tonnes, hay bale weight and yield, fertilizer cost per pound of nutrient and blend rate, and crop break-even.
Seeding Rate Calculator (TKW)
Pounds per acre and kg per hectare of seed from target stand, thousand kernel weight, germination and mortality
Row Crop Seed Spacing and Population
Inches between seeds and seeds per acre for a target plant population, plus plants per acre from a stand count
Sprayer Calibration (Gallons per Acre)
Gallons per acre from nozzle output, speed and spacing, the nozzle GPM for a target rate, and acres per tank
Acre-Inch Irrigation Calculator
Gallons, pumping hours and GPM per acre from acres, inches to apply, pump flow and system efficiency
Grain Bin Capacity Calculator
Bushels in a round or rectangular grain bin from size and grain depth, with optional peak and weight
Bushels to Tonnes Converter
Bushels, tonnes and tons by crop, bushels per acre to tonnes per hectare, and price per bushel to price per tonne
Hay Bale Weight and Yield Calculator
Round or square bale weight from size and density, tons per acre from bales cut, and bales to feed a herd
Fertilizer Cost per Pound of Nutrient
Cost per pound of N, P2O5 or K2O from the analysis and price per ton, with credit for other nutrients
Fertilizer Blend Rate and Cost per Acre
Product rate in lb per acre for target N, P2O5 and K2O from a blend analysis, with cost per acre and total tons
Crop Break-Even Price and Yield Calculator
Break-even price and yield, revenue and profit per acre from your costs per acre, expected yield and price
