“…O uso de HDLs carregados com P para aplicação como fertilizante em cultivos de alface (Lactuca sativa L.) foi estudado pelos autores. 124 O material pós processo de adsorção com fósforo foi chamado de HDL-P. A melhor forma de aplicação desse material, segundo os autores, foi a incorporação do HDL-P em substrato de turfa na concentração 1,0% m/m. Plantas tratadas com esse grupo apresentaram 21% a mais de biomassa que o grupo controle, além de maior retenção de água.…”

“…Não foi detectada lixiviação significativa de alumínio em concentrações tóxicas. 124 Como os materiais inorgânicos e argilosos estudados para remoção de fósforo apresentam em sua composição, em geral, magnésio, alumínio, lantânio, zinco ou ferro, 16,92,[125][126][127][128] a toxicidade no solo e para plantas desses elementos é um parâmetro importante a ser investigado. Nota-se que muitos estudos não realizam os testes com plantas e ensaios de fitotoxicidade.…”

SUSTAINABILITY IN PHOSPHORUS USE: A BIBLIOGRAPHIC REVIEW FOCUSING ON THE CURRENT SITUATION IN THE STATE OF SÃO PAULO, BRAZIL. Phosphorus is a non-renewable element essential for the existence of life and also for food security. This resource has the property of limiting plant growth, becoming a fundamental part of agricultural production. On the other hand, when this element is present in high concentrations in aquatic environments, it can start a phenomenon called eutrophication, which causes a series of changes in biological succession processes and strongly negative impacts on species’ biodiversity and wealth. In this context, this work aimed, from an extensive bibliographical review, to gather strategic and essential information related to phosphorus sustainability, provoking a reflection regarding scenarios that involve this indispensable nutrient, focusing on the current situation of the State of São Paulo, Brazil, an important case study, both for the Brazilian and international scenario, by a gathering of data on the current situation of two of the main watersheds in the corresponding region. Relevant technologies used for phosphorus removal in eutrophicated environments are also addressed. Finally, the possibility of reusing the nutrients present in eutrophicated water bodies as an alternative source of phosphate fertilizer for agriculture is demonstrated.

“…Securing sufficient P will be critical for future food security [46]. Phosphorus is a vital element required in relatively large quantities for the development of plants, which are usually derived from a nonrenewable phosphate rock resource [48][49][50][51]. Globally, about 50-60% of the phosphorus-based fertilizer need is attained by mineral fertilizer [52].…”

This paper reviews relevant facts and statistics about the benefits and impacts of the growing use of chemical fertilizer with a focus on soil fertility, crop productivity, and alternative sources of biofertilizers. Agriculture in Ethiopia is the main source of the economy, and it is the key contributor of the export value and provider of raw materials to processing industries. However, Ethiopian agronomical production is characterized by low output, lack of infrastructure, and low level of technology and is enormously dependent on rainfall availability. In Ethiopia, soil fertility reduction is evolving as a serious contest causing low crop yields, and research findings reported that, at the country level, nutrient balance indicated a depletion rate of 122 kg N ha−1 yr−1, 13 kg P ha−1 yr−1, and 82 kg K ha−1 yr−1. To control soil fertility depletion, primarily fertilizers are used as the source of essential plant nutrients. In Ethiopia, the use of chemical fertilizers to increase crop production was low relative to other developing countries; however, now, it is steadily increasing. Urea and diammonium phosphate are common practices for maintaining soil fertility. Chemical fertilizer consumption increased from 12 kg/ha in 1996 to 36.2 kg/ha in 2018. The main cereals’ production increased from 16.5 quintal/ha in 2009 to 23.94 quintal/ha in 2018.

“…They also offer a relatively high surface area, crystalline structure, water resistance, and biocompatibility . Some studies also reported the prospects of LDHs as sources of macro- and micronutrients. − Due to their high anion-exchange capacity, LDHs are considered to be suitable sorbents for various types of anions, including agricultural nutrients. The anion adsorption by LDHs occurs via various mechanisms such as electrostatic attraction (on the surface), anion exchange with interlayer anions, and surface complexation .…”

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.
