“…In general, until 22 DAT, the addition of H 2 O 2 increased the Cl − concentration in the nutrient solution but decreased afterwards. At low pH conditions, Cl − solubility increases; then, when the chlorides oxidate in chlorine oxides, they are eliminated as a gas and therefore Cl − concentration decreases at the end of the cultivation for oxyfertigated solutions [47].…”

“…The behavior of Cl − concentration could be due to the joined effects of the low pH, related to the higher solubility of Cl − in the leached solution, and the oxidation of Cl − in chlorine oxides, eliminated in the form of gas, decreasing the concentration of Cl − at the last period of the trial [47]. However, this ion does not cause a problem in crops that have a short growth period and a low transpiration rate, e.g., lettuce (Lactuca sativa) [83] as well as some ornamental plants such as Cordyline fruticose.…”

Leachate reuse is a helpful tool that contributes to the sustainability of agricultural systems, but it requires previous disinfection. Hydrogen peroxide can be found among the disinfectants frequently applied in ecological production systems. Moreover, it can improve the oxygenation of the root system. The objective of this work was to study its effect on C. fruticosa plants fertigated with leachates. A split-plot design with six treatments, three without an H2O2 supply (S0) and three with an H2O2 supply dosage at 2% (SH2O2), was arranged: raw leachate from C. lanatus (L100), raw leachate from C. lanatus diluted with tap water until EC of 2.5 dS m−1 (LWD), and raw leachate from C. lanatus diluted with standard nutrient solution until EC of 2.5 dS m−1 (LNSD). The results produced data about the evolution of the nutrient and leachate solutions throughout the cultivation period. Morphological (height, leaf number, leaf area, total fresh weight, relative water status, and dry weight) and physiological (chlorophyll a, chlorophyll b, carotenoids, chlorophyll a+b, and proline) parameters were studied to reveal the plant response. The efficiency of nutrient utilization was higher with the LWD treatment, and water and nitrogen utilization efficiency decreased under the H2O2 supply. In conclusion, the reuse of diluted leachate is advised for nutritionally undemanding crops, such as C. fruticosa; moreover, the H2O2 supply improved tolerance to salinity and enhanced root growth and Red-Green-Blue (RGB) values.

Mediante el uso de la hidroponía es posible aumentar el aprovechamiento de los nutrientes por los cultivos; sin embargo, el balance de la solución nutritiva (SN) debe ser adecuado, o de lo contrario, se puede afectar negativamente la respuesta de la planta. El objetivo del estudio fue evaluar, durante tres etapas, el crecimiento de plantas de lechuga en hidroponía, usando macronutrientes (NO3-, H2PO4-, SO42- y K+, Ca2+, Mg2+) en las siguientes cinco proporciones: 60:5:35 y 35:45:20 (SN-1, Steiner-testigo); 80:2,5:17,5 y 35:45:20 (SN-2); 40:7,5:52,5 y 35:45:20 (SN-3); 60:5:35 y 43,7:38,9:17,3 (SN-4); y 60:5:35 y 20:55,4:24,6 (SN-5). El ensayo se condujo en un diseño de bloques al azar con seis repeticiones. Se determinó el índice de clorofila (IC), área foliar (AF) y peso fresco de la planta (PF), así como peso seco de hojas (PSH), cogollo (PSC) y raíz (PSR). La SN-2 superó en las tres etapas a otros tratamientos propuestos en las variables de PF, AF e IC, y en determinadas etapas superó al tratamiento testigo. En las variables de peso seco, sólo hubo diferencias en la etapa final para PSH y PSR en la que la SN-2 superó a otras SN propuestas, pero no se diferenció de la SN de Steiner (testigo). El tratamiento con alta proporción de nitrato (SN-2) superó al resto de los tratamientos en diferentes variables, así como eventualmente a la SN de Steiner, por lo que se debería considerar en futuras evaluaciones de soluciones nutritivas para cultivos de hoja.
