Farming and Agriculture Calculators
Farming and agriculture calculators for livestock management, crop yield planning, grain storage, irrigation needs, and farm operations.
Compost Carbon-to-Nitrogen (C:N) Ratio Calculator
Calculate the C:N ratio of a compost mix from greens and browns. Get target 25:1 to 30:1 ratio, weight balance, and material lookup for active hot composting.
Crop Yield Estimator
Estimate total crop yield and revenue from planted area, expected yield per acre, and market price. Compare to break-even price.
Farm Break-Even Price Calculator
Calculate the minimum crop price you need to cover all fixed and variable production costs and determine your profit margin at current market prices.
Hay Storage Calculator (Livestock Winter Feed)
Calculate how many hay bales you need to feed your livestock through winter. Covers cattle, horses, sheep, and goats by weight and feeding duration.
Livestock Slaughter and Carcass Yield Calculator
Calculate carcass weight, dressing percentage, and retail cut yield from live animal weight for cattle, hogs, sheep, and goats.
Seed Germination and Seeding Rate Calculator
Calculate how many seeds to plant per acre to achieve your target plant stand, accounting for germination rate and field emergence losses.
Crop Fertilizer NPK Calculator
Calculate fertilizer amount to meet crop NPK requirements. Convert between fertilizer grades, find nutrient rates per hectare or acre, and plan applications.
Crop Water Requirement Calculator
Calculate crop water requirements and irrigation needs using the FAO Penman-Monteith method. Find reference ET and crop ETc from Kc coefficients.
Feed Conversion Ratio (FCR) Calculator
Calculate feed conversion ratio (FCR) for livestock: how much feed produces one unit of weight gain. Compare FCR for cattle, pigs, chickens, and fish.
Irrigation System Calculator
Calculate drip and sprinkler flow rates, zone coverage, and run times. Size pipes, emitters, and zones for efficient crop and garden irrigation requirements.
Livestock Weight Estimator
Estimate livestock weight from body measurements without a scale. Calculate cattle, horse, and pig weight from heart girth and body length.
Cattle per Acre (Stocking Rate) Calculator
Calculate the proper stocking rate for cattle based on pasture size, forage quality, and animal weight. Prevent overgrazing and optimize pasture health.
Grain Bin Volume and Capacity Calculator
Calculate the storage capacity of a round grain bin in bushels and tons. Enter diameter and grain height for accurate volume estimates.
VPD Calculator for Plants (Vapor Pressure Deficit)
Calculate Vapor Pressure Deficit (VPD) for plant growing environments. Find the ideal VPD range for seedlings, vegetative growth, and flowering stages.
