Abstract
Plant nutrition is the practice of providing to the plant the right nutrient, in the right amount, in the right place, at the right time. This paper gives an overview of the roles that each of the 16 essential nutrients have in plant nutrition, their relative mobility as related to deficiency symptom expression, and what is generally known about nutrient responses to field applications on potatoes (Solanum tuberosum L.) in the USA and Canada. Maintaining high crop yields with minimum nutrient losses to the environment is and will continue to be a significant challenge to the potato producer. Additional nutritional research efforts in genetically modified plants, precision agriculture, food quality and safety, fertilizer impurities, and other management concerns should significantly help the producer in this effort.
Resumen
La nutrición vegetal consiste en proporcionar a la planta el nutriente correcto, la cantidad correcta, el lugar correcto y el momento correcto. Este artículo da una visión general de los roles que tiene cada uno de los 16 nutrientes esenciales en la planta, su movilidad en relación con la expresión de los síntomas de deficiencia y lo que generalmente se conoce sobre las respuestas de la aplicación en papa (Solanum tuberosum L.) en el campo, en EUA y Canadá. El hecho de mantener rendimientos altos con pérdida mínima de nutrientes en el suelo es y continuará siendo un desafío significativo para el productor de papa. Cualquier esfuerzo de investigación que se haga sobre nutrición adicional en plantas genéticamente modificadas, agricultura de precisión, calidad alimentaria y seguridad, impurezas de los fertilizantes y otros aspectos de manejo deben ayudar significativamente al productor.
