| description | An alternative to nitrogen leaching in the cultivation of cut flowers is the optimization of the fertigation formula. In order to study the reduction of total nitrogen and the increase in the proportion of ammonium in the NH4+:NO3- ratio, two concentrations of total nitrogen were evaluated under greenhouse conditions (200-140 mg L-1 in the vegetative phase and 160-112 mg L-1 in the productive phase), along with three NH4:NO3- ratios (5:95, 15:85 and 25:75) in standard carnation cv. Don Pedro grown on substrate. The elementary contents of the plant tissue, the pH and the nitrate concentration in the leachate were determined at three times during the cultivation. Higher concentrations of Zn and Cu were observed in the plant tissue with the decrease in the total N; likewise, increases of N and Zn and a decrease of Mg were obtained with the increase in NH4+, which in turn decreased the pH in the substrate. The decrease in the total N did not significantly affect the content of N in the plant tissue, but did significantly affect the content of NO3- and total N in the leachate. |

In order to study the reduction of total nitrogen and the increase in the proportion of ammonium in the NH4+:NO3- ratio, two concentrations of total nitrogen were evaluated under greenhouse conditions (200-140 mg L-1 in the vegetative phase and 160-112 mg L-1 in the productive phase), along with three NH4:NO3- ratios (5:95, 15:85 and 25:75) in standard carnation cv.

Una alternativa a la lixiviación de nitrógeno en el cultivo de flores de corte es la optimización de la fórmula de fertirriego. Con el objetivo de estudiar la reducción de nitrógeno y el aumento de la proporción de amonio en la relación NH4+:NO3-, se evaluaron en condiciones de invernadero dos concentraciones de nitrógeno total (200-140 mg L-1 en fase vegetativa y 160-112 mg L-1 en fase productiva) y tres relaciones de NH4:NO3- (5:95, 15:85 y 25:75) en clavel estándar cv. Don Pedro sembrado en sustrato. Se determinaron en tres momentos de cultivo los contenidos elementales del tejido vegetal, el pH y la concentración de nitrato en los lixiviados. Se observó mayores concentraciones de Zn y Cu en el tejido vegetal con la disminución de N total; así mismo, se obtuvieron incrementos de N y Zn y disminución de Mg con el incremento NH4+, que, a su vez, disminuyó el pH en el sustrato. La disminución de N total no afectó significativamente el contenido de N en el tejido de la planta, pero si el contenido de NO3- y N total en el lixiviado.
