Agriculture & Gardening Calculators
Plan irrigation, planting, fertilizer, livestock feed, and crop yields for gardens, farms, and hydroponic systems.
Top calculators
A short starting set for the most common agriculture & gardening calculators workflows.
Seed Germination Rate Calculator - Planting Quantity & Viability Estimator
Calculate seed germination rates, determine planting quantities needed, and estimate success probability for gardens and farms. Includes viability testing, spacing requirements, and seed quality assessment.
Pasture Stocking Rate Calculator - Balance Forage and Livestock
Estimate how many animals a pasture can support by accounting for forage yield, utilization rate, animal intake, and grazing duration.
Aquaponics System Design and Yield Calculator - Design Optimized Systems
Design aquaponics systems with optimal fish tank, biofilter, and plant grow bed sizing. Calculate fish stocking density, plant yield, nutrient cycling, and system economics for tilapia, trout, and other species.
Lawn Sprinkler Runtime Calculator – How Long to Run Your Sprinklers
Calculate how long to run lawn sprinklers using desired water depth, precipitation rate, lawn size, and flow rate. Get runtime in minutes and total water use.
Hay Bale Yield Calculator - Estimate Bales and Tonnage
Calculate the number of hay bales and total tons harvested from field size, yield per acre, and bale weight.
Rotational Grazing Paddock Planner Calculator
Estimate rotational grazing paddock area and the number of paddocks needed from herd size, animal weight, intake, pasture growth, utilization, grazing days, and rest period.
