YielixCalculators Organized by Farm Task
Find the right tool by the work you need to do today — from irrigation scheduling to feed planning.
Plan Your Irrigation Schedule
Determine crop water demand from ET₀, choose run times, and schedule irrigations around soil moisture depletion.
Calculate Fertilizer & Amendment Rates
Convert soil test recommendations into product quantities, plan lime or gypsum amendments, and model organic matter buildup.
Plan Seeding & Crop Rotation
Calculate germination-adjusted seed rates, target plant populations, score crop rotations, and track growing degree days.
Calibrate Sprayers & Track Safety
Dial in spray application rates, assess drift risk before spraying, and track restricted entry and pre-harvest intervals.
Build Feed Rations & Plan Supply
Formulate balanced rations on a dry-matter basis, estimate hay needs for winter feeding, and calculate livestock water requirements.
Budget Greenhouse Operations
Estimate heating costs from cover material and degree days, size ventilation fans, and calculate ROI on greenhouse investment.
Start With These High-Impact Calculators
One tool from each agricultural domain — irrigation, soil, crop, spray, livestock, and greenhouse — to get you producing results right away.
ET₀ Calculator
Calculate reference evapotranspiration using the FAO-56 Penman-Monteith equation for irrigation planning
NPK Fertilizer Calculator
Calculate fertilizer product quantities to meet target N-P-K rates with multi-product blending and over-application warnings
Seed Rate Calculator
Calculate germination-adjusted seeding rates, weight per acre or hectare, and bags needed — with crop-specific defaults.
Spray Application Rate Calculator
Calculate pesticide dilution rates, product per tank, and total product needed for your field area.
Feed Ration Builder
Build feed rations with multiple ingredients and see nutrient totals on a dry-matter basis with CP, TDN, and NDF breakdown.
Greenhouse Heating Cost Calculator
Estimate seasonal greenhouse heating costs from cover material U-value, glazing area, heating degree days, and fuel type.
Irrigation & Water
10 calculators for water requirements, pump sizing, pipe friction, drip design, soil moisture, and water cost.
Soil & Fertilizer
9 calculators for NPK rates, lime, gypsum, compost, organic matter planning, and micronutrients.
Crop Planning
7 calculators for yield estimation, harvest loss, crop rotation scoring, GDD accumulation, and seed rates.
Pest & Spray
4 calculators for application rates, REI/PHI tracking, IPM cost-benefit analysis, and drift risk.
Livestock & Feed
5 calculators for feed ration building, dry matter intake, feed conversion ratio, hay needs, and water requirements.
Greenhouse
7 calculators for heating cost, fan sizing, climate, light, fertigation, and investment planning.
Grain & Post-Harvest
2 calculators for bin capacity and moisture-shrink planning before grain is stored or marketed.
Farm Economics
4 calculators for crop break-even, enterprise profit, field capacity, and nutrient value decisions.
How Yielix Helps Your Operation
Transparent methods, actionable results, and zero cost — built for farmers, agronomists, and land managers who need reliable planning numbers.
Published Agronomic Methods
Every calculator documents which formula it uses — FAO-56 Penman-Monteith for ET₀, SMP/Adams-Evans buffer methods for lime, NRC standards for feed intake — so you can verify the science yourself.
Instant, Unit-Flexible Results
Toggle between metric and imperial units, enter your own field data, and get actionable numbers in seconds — no spreadsheets, no software licenses.
100% Free, No Account Required
All 48 calculators across eight agricultural categories are free to use immediately from any device.
Worked Examples & Interpretation
Each calculator includes a step-by-step worked example and result interpretation guidance so you understand what the numbers mean for your operation.
