Fuel Consumption per Hectare
Calculate the fuel consumption per hectare of a mechanized operation, consumption = hourly consumption ÷ field capacity, dividing the tractor's hourly consumption (L/h) by the effective field capacity (ha/h). The result, in liters per hectare, is the practical indicator to budget the fuel cost of a farming operation and compare the energy efficiency of machines and settings. Heavy operations (subsoiling) consume far more L/ha than light ones (spraying). Combined with the diesel price and the total area, it gives the season's fuel cost. Enter the hourly consumption and the field capacity.

Fuel consumption per hectare
The cost of fuel is one of the largest operating expenses in mechanized agriculture, and the most useful way to express it is per hectare, not per hour — because the crop season is planned by area. The calculation combines two figures: consumption = hourly consumption ÷ field capacity, dividing how much diesel the tractor burns per hour (L/h, measured or taken from tables) by the effective field capacity (ha/h, how many hectares it covers in an hour). The result, in liters per hectare, normalizes consumption against the area worked. The widest variation comes from the type of operation: heavy tillage operations (subsoiling, plowing) demand high draft force, run at high hourly consumption and low capacity (they advance slowly) — which adds up to many L/ha; light operations (spraying, no-till seeding) burn less per hour and cover ground faster — few L/ha. Knowing the per-hectare consumption of each operation lets you budget the fuel cost of the season (L/ha × area × diesel price), compare the efficiency of different machines, settings and speeds, and spot where savings are possible (a poor setting, excessive wheel slip or a badly adjusted implement sends consumption soaring). In farm management systems and precision agriculture, real-time L/ha monitoring (through tractor telemetry) has become a key efficiency indicator. Enter the hourly consumption and the field capacity.

Effective Field Capacity
Calculate the effective field capacity of a mechanized farming operation, FC = (v × L × Ef) ÷ 10, from the working speed v (km/h), the effective working width L (m) and the field efficiency Ef (decimal). The result, in hectares per hour, is the area the machine actually works per hour, already discounting time losses with turns, refills and overlaps (efficiency). The factor 10 adjusts the units. It is central to mechanization planning: it sets how many machines and hours are needed to complete an operation (planting, spraying, harvesting) in the available window. Enter the speed, the width and the field efficiency.
Worked Area per Machine
Calculate the area worked by a farm machine, A = field capacity × time, multiplying the effective field capacity (ha/h) by the available operating time (h). The result, in hectares, is how much the machine can cover in a shift — direct input for operational planning: how many hours (or days) are needed to complete the planting, spraying or harvesting of an area, and whether the machine fleet meets the agronomic window (the period in which the operation must occur). Undersizing the fleet delays critical operations and reduces yield. Enter the field capacity and the operating time.
Tractor Wheel Slip
Calculate the wheel slip of a tractor, slip = (1 − D_loaded ÷ D_unloaded) × 100%, comparing the distance traveled in a number of wheel revolutions under load (D_loaded) and unloaded (D_unloaded). The result, in %, measures how much the wheels spin without advancing, by slipping on the soil. Excessive slip wastes power and fuel and compacts the soil; zero slip indicates lack of traction. The ideal range for farm tractors is typically 8 to 15% on firm soil, adjusted with ballast and tire pressure. It is a key traction efficiency indicator. Enter the loaded and unloaded distances.
