Agriculture & Farming
Seed, fertilizer, irrigation, and crop planning calculators
Seed / Fertilizer Application Rate
Calculate exact seed and fertilizer requirements per acre/hectare with purity/germination adjustments, row/in-row spacing, N-P-K analysis, liquid densities, and cost—plus calibration helpers.
Irrigation Water Requirement
Compute total irrigation water by crop and area using ET₀, crop coefficients (Kc), effective rainfall, soil water balance, and system efficiency—plus schedule, flow, pump energy, and cost.
Crop Yield Estimator
Project projected yield using plant density, per-plant yield, crop presets, and loss/moisture adjustments.
Greenhouse Area & Capacity
Estimate plants per m² and total capacity from greenhouse size, aisles, benches, pot/tray size, spacing pattern, tiers, and crop turnover.
Irrigation Scheduling by Crop & Evapotranspiration
Plan irrigation schedules using crop water needs, ET₀ reference evapotranspiration, and crop coefficients. Estimate when and how much to irrigate based on soil moisture depletion.
Crop Rotation Planner
Plan multi-year crop rotations by allocating acres per crop. Balance nutrient needs, pest management, and soil health across your fields over multiple seasons.
Fertilizer Cost per Nutrient Unit Calculator
Calculate the cost per unit of N, P, and K from fertilizer blends. Compare products to find the most economical source for each nutrient.
Livestock Stocking Density Planner
Calculate optimal stocking density for livestock based on pasture size, forage availability, animal type, and grazing system. Plan rotational grazing schedules.
Greenhouse Heating & Cooling Load Estimator
Estimate rough heating and cooling requirements for greenhouses based on dimensions, glazing type, climate zone, and target temperature ranges.
Tree Planting Layout Planner
Plan tree planting layouts with optimal spacing and row configurations. Calculate total tree count, spacing patterns, and land utilization for orchards or forestry.
Windbreak / Shelterbelt Design Helper
Design windbreaks and shelterbelts with optimal row spacing, species selection, and protected zone calculations. Estimate wind reduction and coverage area.
