Application of the Adsorptive Stripping Voltammetry-Response Surface Methodology (AdSV-RSM) in the simultaneous determination of copper ions in an aquaponics system

ABSTRACT In this paper, the application of the Adsorptive Stripping Voltammetry-Response Surface Methodology (AdSV-RSM) in the simultaneous determination of copper ions in an aquaponics system has been studied. The effects of several parameters studied include variations in Calcein concentration, pH, accumulation potential, and accumulation time. The study design used was Response Surface Methodology (RSM) with 4 factors/variables, 3 levels and 31 treatment combinations. The results of the study, analysis of variance was carried out, and it was decided to accept the second-order model, which means that the independent variable has a significant effect on the response variable (peak current). Based on data analysis with the RSM, the determination of Cu(II) obtained the optimum conditions including peak current 349.196 (Ip); calcein concentration 0.616339 µg/L; pH 6.06208; potential accumulation −0.721104 V and time accumulation of 69.3744 s. The response surface method has been applied successfully for Cu(II) analysis in water, fish, and hydroponic plant aquaponics system, which is an integration between fish farming and hydroponic plant cultivation, with the relative standard deviation value was 1.12%, recovery of 99.23% and the detection limit of 0.75 μg/L.

SDG Implementation through Technology? Governing Food-Water-Technology Nexus Challenges in Urban Agriculture

The 2030 Agenda for Sustainable Development emphasizes the importance of technology as a pillar for the implementation of the Sustainable Development Goals (SDGs). Technology innovation promises benefits especially for the implementation of SDG 2 to end hunger, achieve food security and improved nutrition, and promote sustainable agriculture. Contributing to current debates on SDG implementation, technology innovation, and cross-sectoral governance, we argue that technology innovation carries both the potential to contribute to global goal implementation and the risk of posing new governance challenges. Applying a food-water-technology nexus (FWTN) perspective, we conduct a case study on an emerging technology in urban agricultural production in Germany. The technology connects the wastewater treatment system and the agricultural production system and projects the transformation of a conventional sewage treatment plant into a ‘NEWtrient®-Center,’ which draws the essential resources for urban hydroponic plant cultivation from municipal wastewater. Building on qualitative and participatory research methods, the study provides deeper insights into the governance implications of FWTN issues stemming from the emerging technology. The analysis shows that this technology has the potential to facilitate SDG implementation, but simultaneously fuels new sector interlinkages between water and food and policy demands that substantiate the need for more integrated policymaking to ensure the smart use of technology to reach the SDGs.

The effect of fullerene on the physiological and biochemical parameters of barley plants in hydroponic culture

The differences in the response to the action of fullerene of barley plants (Hordeum vulgare L., cultivar Yakub) grown in water culture (in distillated water or Knop’s nutrient solution) with the addition of fullerene C 60 (10 or 50 mg/l) were studied. The content of chlorophyll, flavonols, and nitrogen balance index (NBI) were evaluated in the 1st leaf during the growing. At the end of the experiment, the relative rate of water loss (RWL) by the leaves was determined, as well as the dry mass of the roots and shoots. The effect of fullerene on the physiological and biochemical parameters of barley plants depended on the concentration of these nanoparticles and the presence of nutrients in the cultivation medium. Under the action of 10 mg/l of fullerene, all investigated parameters were mainly maintained at the level of control values. At the same time, exposure to 50 mg/l of fullerene stimulated a decrease in the content of chlorophyll and flavonols in the first leaf, increased the relative loss of water by the leaves, and slowed down the growth of barley plants grown in water. When 50 mg/l of fullerene was added to the Knop solution, the chlorophyll content in the first leaf increased, the accumulation of flavonols practically did not change, and the NBI increase was more prolonged. In this case, the dry mass of shoots increased, and no significant changes in the relative loss of water by the leaves and root growth were noted. It is assumed that differences in the sensitivity of plants to fullerene during their growth in water and Knop’s nutrient solution are associated, on the one hand, with their anatomical, morphological, and physiological and biochemical characteristics, including the activity of detoxification mechanisms, and, on the other, with possible changes in physicochemical properties nanoparticles in a solution of salts, activation of the delivery of nutrients with the help of fullerene and the influence on the processes that cause the aging of the first leaf to slow down.

Function analysis of nitrogen-responsive transcription factor ZmNLP5 affecting root growth in maize

<p indent=0mm>Improving nitrogen (N) use efficiency of crops is crucial for minimizing N loss and reducing environmental pollution, which is a requirement for the sustainable agriculture. Our previous study found that the transcription factor ZmNLP5 directly regulated the expression of <italic>ZmNIR1</italic>.<italic>1</italic> and promoted nitrogen uptake and assimilation in maize, however, its underlying regulation mechanism is unclear. Here, we performed further phenotype analysis of <italic>zmnlp5 </italic>and wild type (W22) plants in hydroponic culture on sufficient nitrogen (SN) solution and deficient nitrogen (DN) solution. Compared with WT plants, the root length of <italic>zmnlp5</italic> mutant plants was significantly decreased under DN condition. Compared with upper and middle regions of roots, ZmNLP5 was predominantly expressed in root tip regions. Then, we examined the relationship between root length and nitrite content in root tips under a series of nitrite concentrations. The results showed that there was no significant differences in root length between WT and <italic>zmnlp5</italic> until the nitrite concentration reached <sc>2 mmol L^–1</sc> and higher; however, when the concentration of nitrite was higher than <sc>2 mmol L^–1,</sc> the root length of <italic>zmnlp5</italic> was significantly shorter than WT, and the accumulation of nitrite in the root tips of <italic>zmnlp5</italic> was significantly higher than WT. Interestingly, <italic>zmnlp5 </italic>plants also accumulated significantly more nitrite in the root tips than WT under DN condition. The study showed that the transcription factor ZmNLP5 played an important role in the root growth of maize in response to deficient nitrogen condition, and provided the candidate genes for breeding of maize nitrogen use efficiency in the future.

Genetic diversity of VIR Raphanus sativus L. collections on aluminum tolerance.

Radish and small radish (Raphanus sativus L.) are popular and widely cultivated root vegetables in the world, which occupy an important place in human nutrition. Edaphic stressors have a significant impact on their productivity and quality. The main factor determining the phytotoxicity of acidic soils is the increased concentration of mobile aluminum ions in the soil solution. The accumulation of aluminum in root tissues disrupts the processes of cell division, initiation and growth of the lateral roots, the supply of plants with minerals and water. The study of intraspecific variation in aluminum resistance of R. sativus is an important stage for the breeding of these crops. The purpose of this work was to study the genetic diversity of R. sativus crops including 109 accessions of small radish and radish of various ecological and geographical origin, belonging to 23 types, 14 varieties of European, Chinese and Japanese subspecies on aluminum tolerance. In the absence of a rapid assessment methodology specialized for the species studied, a method is used to assess the aluminum resistance of cereals using an eriochrome cyanine R dye, which is based on the recovery or absence of restoration of mitotic activity of the seedlings roots subjected to shock exposure to aluminum. The effect of various concentrations on the vital activity of plants was revealed: a 66-mM concentration of AlCl3 · 6Н2О had a weak toxic effect on R. sativus accessions slowing down root growth; 83 mM contributed to a large differentiation of the small radish accessions and to a lesser extent for radish; 99 mM inhibited further root growth in 13.0 % of small radish accessions and in 7.3 % of radish and had a highly damaging effect. AlCl3 · 6Н2О at a concentration of 99 mM allowed us to identify the most tolerant small radish and radish accessions that originate from countries with a wide distribution of acidic soils. In a result, it was possible to determine the intraspecific variability of small radish and radish plants in the early stages of vegetation and to identify genotypes that are contrasting in their resistance to aluminum. We recommend the AlCl3 · 6Н2О concentration of 83 mM for screening the aluminum resistance of small radish and 99 mM for radish. The modified method that we developed is proposed as a rapid diagnosis of aluminum tolerance for the screening of a wide range of R. sativus genotypes and a subsequent study of contrasting forms during a longer cultivation of plants in hydroponic culture (including elemental analysis of roots and shoots, contrasting in resistance of accessions) as well as reactions of plants in soil conditions.

New Uses of Treated Urban Waste Digestates on Stimulation of Hydroponically Grown Tomato (Solanum lycopersicon L.)

One strategy to re-use solid urban wastes is the production of energy by anaerobic digestion. This process also generates high volume of digestates, which are frequently disposal in landfills. The aim of this work is to assess anaerobic digestates as agricultural inputs. Three different biomethanation wastes from different plants were collected. Firstly, a complete physico-chemical characterization of the wastes was done according to the Spanish regulation, showing that the materials had the 90% of the particles below 25 mm, high values of pH, electric conductivity, organic matter, humic acids and soluble nutrients such as NO3−, SO42−, Ca2+, Mg2+, PO43− and K+. Total concentrations of heavy metals and microbiological parameters were below the threshold levels allowed for agricultural use. The wastes were then treated with a strong acid and a strong base having two different solutions (ATr and BTr, respectively) which were evaluated as biostimulants for tomato plants in hydroponic culture. Those liquid extracts, ATr and BTr, demonstrated their biostimulant ability towards root system of tomato enhancing the hair root density and plant biometric parameters including plants weight and chlorophyll content. This work demonstrates the re-use feasibility of treated digestates in agriculture as fertilizers and more over as feedstock for biostimulants production.
