          Abstract

          RESUMO O fornecimento adequado de nutrientes contribui, de forma significativa, tanto no aumento da produtividade como no aumento do custo da produção. Nesta situação, a otimização de eficiência nutricional é fundamental para ampliar a produtividade e reduzir o custo de produção. Vários fatores, como clima, solo, planta e suas interações, afetam a absorção e a utilização de nutrientes pelas plantas. Para a eficiência máxima de nutrientes, esses fatores devem estar no nível ótimo durante o desenvolvimento da cultura e a revisão de literatura mostra que existe grande potencial de se aumentar a eficiência nutricional através do manejo adequado dos componentes do sistema de produção.

          ABSTRACT The adequate supply of nutrients contributes significantly to increasing crop produtivity as well as cost of production. In this situation, optimizing nutrient use efficiency is fundamental for higher crop productivity and reduced cost of production. Several factors such as climate, soil, plant, and their interactions affect nutrient absorption and utilization by crop plants. To obtain maximum nutrient use efficiency, all these factors should be at an optimum level during crop development. A review of factors affecting nutrient use efficiency demonstrates a large potential to improve nutrient use efficiency by adequate management of cropping system components.
