“…For Baracaldo et al (2018), a reduction of total nitrogen and an increase in the NH 4 + : NO 3 ratio in the fertigation formula modified nutrient contents in carnation cv. Don Pedro plant tissue: with the lower content of total N, the contents of Cu and Zn were significantly increased; the increase in NH 4 + significantly raised the contents of N and Zn and reduced Mg.…”

Although nitrogen is the most widely used fertilizer in agriculture, it contaminates the surface and groundwater through leaching. A decrease in the concentration of total nitrogen and changes in the ammonium:nitrate ratio can provide information for a better use of this nutrient. The objective of this study was to evaluate the effect of a decrease in total nitrogen and an increase in the percentage of N-NH4+ on indicators of growth, productivity, quality and nitrogen use efficiency (NUE) in carnation cultivation. In the Centro Agropecuario Marengo at the Universidad Nacional de Colombia, two concentrations of total nitrogen were evaluated (200-140 mg L-1 in the vegetative phase and 160-112 mg L-1 in the productive phase) with three ratios of N-NH4:N-NO3 (5:95, 15:85 and 25:75) in standard carnation plants cv. Don Pedro grown in substrate. In both fertigation formulas, similar productivity and qualities were obtained, and the formula with less total N provided better NUE, mitigating the negative impact of this nutrient on the environment. Likewise, the ammoniacal component played a preponderant role: the number of floral stems per plant decreased as the ammoniacal component increased, similar to that observed with the percentage of flowering stems in the ‘Select’ quality grade.

“…Therefore, an appropriate NH 4 + /NO 3 − ratio (25/75) may promote root growth by maintaining the pH value, thereby increasing biomass. The pH of the rhizosphere also affects the absorption of NH 4 + and NO 3 − by plants [31]. With the growth and development of plants, the pH value of the nutrient solution gradually decreased under a medium NH 4 + /NO 3 − ratio (25/75).…”

High NH4+/NO3− Ratio Inhibits the Growth and Nitrogen Uptake of Chinese Kale at the Late Growth Stage by Ammonia Toxicity

et al. 2021

The aim of this study was to determine the effects of various NH4+/NO3− ratios in a nutrient solution on the growth and nitrogen uptake of Chinese kale under hydroponic conditions. The four NH4+/NO3− ratios in the nutrient solution were CK (0/100), T1 (10/90), T2 (25/75), and T3 (50/50). An appropriate NH4+/NO3− ratio (10/90, 25/75) promoted the growth of Chinese kale. T2 produced the highest fresh and dry weight among treatments, and all indices of seedling root growth were the highest under T2. A high NH4+/NO3− ratio (50/50) promoted the growth of Chinese kale seedlings at the early stage but inhibited growth at the late growth stage. At harvest, the nutrient solution showed acidity. The pH value was the lowest in T3, whereas NH4+ and NH4+/NO3− ratios were the highest, which caused ammonium toxicity. Total N accumulation and N use efficiency were the highest in T2, and total N accumulation was the lowest in T3. Principal component analysis showed that T2 considerably promoted growth and N absorption of Chinese kale, whereas T3 had a remarkable effect on the pH value. These findings suggest that an appropriate increase in NH4+ promotes the growth and nutrient uptake of Chinese kale by maintaining the pH value and NH4+/NO3− ratios of the nutrient solution, whereas excessive addition of NH4+ may induce rhizosphere acidification and ammonia toxicity, inhibiting plant growth.

“…En Colombia, las plantas de clavel (Dianthus caryophyllus L.), se siembran en contenedores con sustrato; el aporte de los nutrientes, se realiza por concentración y el fertirriego por goteo, con bajos volúmenes en periodos cortos (2 a 8 min) y altas frecuencias, buscando ofertar entre 1000 y 1700 L/m 2 -año (Baracaldo et al 2018; González-Murillo et al 2021).…”

El exceso o déficit en el volumen de fertirriego genera desbalances nutricionales, en razón a que influyen en el pH y la CE, afectando el desempeño de las plantas. Además, el descontrol del volumen de fertirriego puede causar excesos de lixiviados con efectos perjudiciales en el medioambiente. La fertirrigación en la producción de clavel en la Sabana de Bogotá, se hace de forma empiríca, por tanto, es indispensable ajustar el volumen de fertirriego a las necesidades del cultivo, para evitar los problemas mencionados. Por esta razón, se evaluó el efecto del control del volumen de fertirriego con lisímetro de peasada, en comparación con el manejo del fertirriego tradicional, en el desempeño de las plantas de miniclavel, sembradas en sutrato, en condiciones de invernadero. Para la evaluación, se realizó un diseño experimental en bloques completos al azar, con los tratamientos de sistema de cultivo con lisímetro (CL) y sistema de cultivo con fertirriego tradicional sin lisímetro (SL). Las variables evaluadas fueron volumen de riego, contenido nutricional de planta completa en cinco estadios fenológicos, pH y nutrientes mayores y secundarios (Ca-Mg), en el sustrato y en la solución drenada. El CL genera un ahorro en el volumen de fertirriego en comparación con el SL. Se encontraron diferencias en el continuo planta -sustrato -lixiviado, en N, K, Mg, así como en el pH del sustrato. El CL fue más eficiente, al generar mayor acumulación de masa seca, con el uso de menos agua y nutrientes, sin afectar el rendimiento, ni la calidad.
