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.

Capacidade de campo efetiva
A capacidade de campo efetiva responde à pergunta central do planejamento da mecanização agrícola: quantos hectares minha máquina realmente faz por hora? Ela é CC = (v × L × Ef) ÷ 10, combinando a velocidade de trabalho v (km/h), a largura efetiva de trabalho L (m) — a faixa que o implemento realmente cobre a cada passada — e a eficiência de campo Ef (uma fração entre 0 e 1). O produto v × L daria a capacidade teórica (máquina trabalhando ininterruptamente, sem perdas), mas na prática há muito tempo 'improdutivo': manobras de cabeceira (virar no fim do talhão), abastecimentos de insumo e combustível, regulagens, desentupimentos, e sobreposições (passar duas vezes na mesma faixa). A eficiência de campo desconta tudo isso. O fator 10 converte as unidades (km/h × m → ha/h). Conhecer a capacidade efetiva permite dimensionar a frota: dividindo a área total pela capacidade, obtém-se as horas-máquina necessárias, e comparando com a janela agronômica (o prazo em que a operação deve ocorrer para não perder produtividade — plantar na época certa, pulverizar antes da praga se espalhar, colher no ponto), decide-se quantas máquinas comprar ou alugar. Subdimensionar atrasa operações críticas; superdimensionar imobiliza capital. Informe a velocidade, a largura e a eficiência de campo.

Field Efficiency
Calculate the field efficiency of a mechanized operation, Ef = (effective capacity ÷ theoretical capacity) × 100%, dividing the effective field capacity (area actually worked per hour) by the theoretical capacity (the one obtained with no time losses). The result, in %, measures how much of the time the machine actually works, as opposed to headland turns, refills, adjustments, travel and overlaps. Simple operations in large fields have high efficiency (80-90%); complex operations in small, irregular fields, low (60-70%). Improving field efficiency (larger fields, fewer stops) reduces costs. Enter the effective and theoretical capacities.
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.
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.
