| description | Nitrogen is needed in the plantations, but due to their ineffectiveness to absorb it, only a small percentage is assimilated by the plant and the remainder is released in the ambient. The work presented here is focussed in the assessment of the environmental pollution impact by the fertilizer nitrogen, in the hydroponic tomato production. For this study weekly samples of the nutrient solution were taken, from the substrate used, the drained water, and from the plant material, like stem, leaves and fruits, in order to determine the useful nitrogen concentration in the hydroponic tomato growing plant, in Sutamarchán (Boyacá) township. The contents of nitrogen applied to the plant, expressed in relation to the total accumulation, were of 37.93 g. equivalent to 100 % of the N applied. From this 100 % applied only 36% is absorved by the plant and the rest, is discharged. Of the total N application the 0.22051 g (0.6%) is drained, 13,665 (36%) g is absorbed by the plant and the remaining 24.049 g (63.4%) accumulates in the substrate. The investigation determined that there are significant deficiencies in the N application as from 100% applied, only 36% is assimilated by the plant. This indicates that a reduction should be made in the application of nitrogen fertilizers, by rationalizing the nutrients supply to the tomato crop, in order to reduce the environmental impacts and optimize the use of resources. In this sense, the research direction on the best fertirrigation management in recirculating hydroponic systems, will contribute to a more sustainable development. |

El nitrógeno es necesario para las plantas, pero debido a la ineficacia de estas para absorberlo, tan solo un bajo porcentaje es asimilado, y el restante es liberado al ambiente. El trabajo que aquí se presenta se enfocó en determinar la dinámica del nitrógeno en la producción de tomate hidropónico con sistema de drenaje abierto y bajo condiciones de invernadero en la finca Hortifresh S.A., ubicada en el municipio de Sutamarchán (Boyacá). Para el desarrollo de este trabajo se realizaron semanalmente muestreos de la solución nutritiva, del sustrato utilizado, del agua de drenaje y del material vegetal (tallo, hojas y frutos), con el fin de determinar la concentración de nitrógeno aprovechable por la planta en el cultivo de tomate hidropónico. Los contenidos de N aplicados a la planta, expresados en relación con la acumulación total, fueron de 37,93 g, que equivalen al 100% del N aplicado. Del N total aplicado, el 0,6% (0,22051 g) es drenado, el 36% (13,665 g) es absorbido por la planta y el restante 63,4% (24,049 g) se acumula en el sustrato. Que solo el 36% del N aplicado sea asimilado por la planta, según la investigación, indica que se debe reducir la aplicación de fertilizantes nitrogenados y hacer uso racional del suministro de nutrientes que el cultivo de tomate necesita, con el propósito de reducir el impacto ambiental y optimizar el aprovechamiento de los recursos, en este sentido, la investigación sobre el mejor manejo de la fertirrigación en sistemas hidropónicos con recirculación contribuirá a un desarrollo más sostenible de estos.
