1. In economics, the additional input required to produce one more unit of output; the incremental amount of a factor of production needed to increase production by one unit.
The marginal input of labor increased as the factory expanded production.
O insumo marginal de trabalho aumentou conforme a fábrica expandiu a produção.
2. In agriculture and resource management, inputs (such as fertilizer, water, or seeds) applied in additional quantities beyond standard levels to achieve incremental gains in yield.
Farmers analyzed the marginal input of fertilizer to determine optimal application rates.
Os agricultores analisaram o insumo marginal de fertilizante para determinar as taxas de aplicação ótimas.
