Crop Yield Calculator
Estimate total crop yield per acre by multiplying plant population by per-plant production.
Fertilizer Application Rate Calculator
Calculate the pounds of fertilizer needed to raise soil nutrient levels to a target based on field size, soil-test results, fertilizer concentration, and application efficiency.
Seed Spacing Calculator
Calculate plant population per acre from row spacing and in-row plant spacing using the standard 43,560 ft² per acre.
Irrigation Water Requirement Calculator
Calculate daily irrigation water requirement in gallons based on crop water demand (Kc × reference ET), rainfall, system efficiency, and field area.
Livestock Feed Conversion Calculator
Calculate the total feed cost for a livestock group from animal count, daily feed intake, days on feed, and feed cost per ton, with a default 10% adjustment for retained value in the gain.
Pasture Carrying Capacity Calculator
Estimate how many animals your pasture can sustainably support year-round.
Greenhouse Heating Cost Calculator
Estimates the daily cost to heat a greenhouse based on its size, the inside-outside temperature gap, and fuel price.
Lime Requirement Calculator
Calculate how many pounds of lime to apply to raise your soil pH to the target level for optimal crop growth.
Grain Drying Cost Calculator
Estimate the total cost to dry a grain lot from harvest moisture down to a safe storage level.
Pesticide Spray Volume Calculator
Calculates total spray volume and pesticide product needed for a given field by combining field area, carrier volume, and product rate.
Dairy Production Calculator
Estimate your herd's daily and annual milk output by entering the number of cows and average milk yield per cow.
Field Area Calculator
Convert field dimensions in feet into acres instantly using this Field Area Calculator.
Crop Insurance Value Calculator
Calculate the total dollar value of your crop insurance coverage based on insured acres, guaranteed yield, and the price election.
Machinery Operating Cost Calculator
Estimate the hourly operating cost of any piece of farm machinery by combining fuel and maintenance expenses.
Chicken Egg Production Calculator
Calculate how many eggs your flock produces per day by entering the number of hens and their daily laying rate.
Compost C:N Ratio Calculator
Find the ideal carbon-to-nitrogen ratio for your compost pile by entering the weight and nutrient content of your brown and green materials.
Orchard Tree Spacing Calculator
Estimate how many fruit or nut trees fit in one acre based on your row spacing and in-row tree spacing.
Silage Storage Capacity Calculator
Calculate how many tons of silage a cylindrical upright silo can hold based on its diameter, height, and the packed density of your forage.
Cover Crop Seeding Rate Calculator
Calculate the total seed quantity needed for a cover crop or cover crop mixture given your field size and target seeding rate.
Greenhouse CO2 Requirement Calculator
Estimate the volume of CO₂ gas needed to raise greenhouse air concentration to a target level based on the structure's volume.
Crop Yield Calculator
Estimate total crop yield per acre by combining plant population, germination rate, harvest efficiency, and average yield per plant.
Seed Rate Calculator
Calculate the pounds of seed needed per acre to achieve a target plant population, adjusting for germination percentage, seed vigor, seed size, and field conditions.
Greenhouse Ventilation Calculator
Estimates the fan capacity (CFM) required to maintain a target temperature inside a greenhouse based on its footprint and the temperature differential with outside air.
Pasture Stocking Rate Calculator
Calculates the number of animal units a pasture can sustainably support based on forage production, utilization rate, and grazing system.
Livestock Feed Calculator
Calculates the estimated monthly feed cost for a herd based on animal count, average weight, species, and feed price per ton.
Farm Profitability Calculator
Estimates total farm profit by combining crop revenue, government payments, and per-acre production costs across the entire operation.
Pesticide Mixing Calculator
Calculates how many pounds of pesticide product to add to a spray tank for a given field size, application rate, and active ingredient concentration.
Crop Yield Profit Calculator
Calculate the expected net profit from a crop by weighing total revenue against seed, fertilizer, and other per-acre production costs.
