Crop planning, yield, and variety calculators. Browse our free crops tools below — all calculators are instant, accurate, and require no sign-up.
Aquaponic Feed-to-Plant Ratio Calculator — Calculate the balanced ratio of fish feed input to plant growing area in aquaponic systems. Match nutrient output from fish to plant uptake capacity.
Cover Crop Selector — Select the best cover crop species based on your management goals — nitrogen fixation, erosion control, compaction relief, or weed suppression.
Crop Calendar Calculator — Generate a crop calendar with key growth stage dates from planting through harvest using GDD milestones. Plan scouting and management timing.
Crop Rotation Planner — Plan multi-year crop rotations with nitrogen credit tracking, disease break years, and crop family rules. Optimize soil health and reduce input costs.
Crop Variety Comparison Calculator — Compare crop varieties side by side on maturity, yield, disease resistance, seed cost, and estimated ROI. Choose the best variety for your operation.
Expected Yield Per Acre Calculator — Estimate expected crop yield per acre using trend yield adjusted for soil quality, management level, and weather conditions. Plan realistic production targets.
Grafting Success Rate Calculator — Estimate the number of successful grafts from total attempts based on your grafting success percentage. Plan rootstock and scion wood quantities.
Growing Degree Days (GDD) Calculator — Calculate accumulated growing degree days from daily high and low temperatures. Track crop development stages with GDD heat unit summation.
Growing Season Length Calculator — Calculate growing season length in days between last spring frost and first fall frost. Ensure your crops have enough time to reach maturity.
Harvest Date Estimator — Estimate crop harvest date from planting date, relative maturity rating, and a weather adjustment factor. Plan harvest logistics in advance.
Hydroponic Nutrient Solution Calculator — Calculate stock solution dilution ratios, target EC, and pH ranges for hydroponic nutrient management. Mix precise nutrient solutions for soilless growing.
Indoor Growing Light Hours Calculator — Calculate Daily Light Integral (DLI) based on PPFD and photoperiod. Determine how many hours of supplemental light your indoor crops need each day.
Plant Population per Acre Calculator — Calculate plant population per acre from row spacing and in-row plant spacing. Essential for stand assessment and yield estimation.
Vertical Farm Layer Yield Calculator — Estimate annual yield from a vertical farm based on growing layers, area per layer, crop cycles per year, and yield per cycle. Plan indoor farm productivity.
