“…Ureña-Amate and co-workers reported similar observations on soil solution where the 50% nitrate released was higher for the simulated soil solution medium than for the decarbonated water medium. Berber et al demonstrated that in a neutral soil solution, 70% of nitrate was released from Mg/Al LDH within 8 days, which was in agreement with the observations of the present study.…”

“…83 Urenã-Amate and coworkers 84 reported similar observations on soil solution where the 50% nitrate released was higher for the simulated soil solution medium than for the decarbonated water medium. Berber et al 85 demonstrated that in a neutral soil solution, 70% of nitrate was released from Mg/Al LDH within 8 days, which was in agreement with the observations of the present study. Nitrate release studies also indicated that the composite bead LB was capable of retaining a higher amount of nitrate at both pH conditions, demonstrating a significantly slower release rate when compared to LDH alone in powder form.…”

Nitrate-loaded Zn/Al, Mg/Al, and Mg−Zn/Al layered double hydroxides (LDHs) were synthesized using the coprecipitation method. The slow-release properties of LDHs were measured in powder form at various pH conditions. Sodium alginate was used to encapsulate Mg/Al LDH to produce composite beads (LB) to further slow down the release of nitrate ions. The prepared LDH samples and LB were characterized by X-ray diffraction, attenuated total reflectance Fourier transform infrared spectroscopy, thermogravimetric analysis, and inductively coupled plasma optical emission spectroscopy. The surface morphologies of LDHs and LB were obtained from scanning electron microscopy analysis. The slowrelease properties of the materials were evaluated using a kinetic study of nitrate release in tap water, soil solution, as well as plant growth experiments using coriander (Coriandrum sativum). The nitrate release ability of LDHs and LB was compared with a soluble nitrate source. The plant growth experiments showed that all three LDHs were able to supply an adequate amount of nitrate to the plant similar to the soluble fertilizer while maintaining the availability of nitrate over extended periods. The ability of LDHs to increase soil pH was also demonstrated.

“…The basal spacings (d) as calculated by Bragg's law (nλ = 2d sin θ), using the (003) reflection, were 8.9, 8.89, and 8.89 Å for Zn/Al, Mg/Al, and Mg-Zn/Al-LDH, respectively. Berber et al 46 and Beni ́cio et al 47 reported a d spacing of 8.9 Å for NO 3 − -intercalated Mg/Al-LDH. Similar d spacings of 8.84 and 8.53 Å were reported for NO 3 −intercalated Zn/Al-LDH by Mahjoubi et al 48 and Velu et al, 49 where the synthesis was done by a coprecipitation method using NaOH in the presence of excess NO 3 − anions; this result has good similarity to the values obtained in this study.…”

Application of Layered Double Hydroxides as a Slow-Release Phosphate Source: A Comparison of Hydroponic and Soil Systems

et al. 2023

The utilization of slow-release fertilizer materials capable of responding to their environment and releasing nutrient ions efficiently over a prolonged period is an emerging research area in agricultural materials sciences. In this study, two-dimensional layered materials were prepared to release phosphor ions (P) slowly into the soil as well as in the hydroponic system. Various P-intercalated layered double hydroxides (LDHs) (Mg/Al, Zn/Al, and Mg-Zn/Al-LDHs) with a molar ratio of 2:1 were synthesized using an ion-exchange method from corresponding LDHs containing NO3 – ions within the layers. Sodium alginate (SA) was used to encapsulate P-intercalated Mg/Al-LDH to produce bionanocomposite beads (LB) to check the effect of the biopolymer matrix on the release characteristics. The prepared materials were characterized by XRD and FTIR to confirm the incorporation of P in LDHs. TGA, SEM, and elemental analysis were also performed to study the thermal decomposition pattern, surface morphology, and chemical composition of synthesized materials. The P-release experiments were conducted in a soil solution. The performance of the prepared materials was investigated in soil as well as in a hydroponic system for tomato plants under a controlled atmosphere of humidity, temperature, and light. The fertilization ability of the prepared materials was compared with that of a soluble P source (KH2PO4), commercial hydroponic fertilizer (Nutrifeed), and a commercial soil slow-release fertilizer (Wonder plant starter). The prepared materials demonstrated a slow release of P in the soil solution. P-intercalated LDHs were not very effective under hydroponic conditions; however, the LDHs were more effective in the soil system in terms of dry matter production and P content in dry matter. Furthermore, LDHs were able to increase the soil pH value over time.

“…[Zn–Al–NO 3 ]–LDH (ZLDH) was synthesized by a co-precipitation method. 8,13,35 A 30 mL solution of Zn(NO 3 ) 2 ·6H 2 O and Al(NO 3 ) 3 ·9H 2 O in 3 : 1 ratio was added to 30 mL of 1 M solution of NaNO 3 in Milli-Q water, with constant addition of a 2 M NaOH solution to control the pH and precipitate LDH, keeping the temperature at 75 °C. The nitrogen atmosphere was maintained throughout to minimize CO 3 2− intercalation.…”
