“…Further, the acidic pH influents might be regulated by the worm and microbial activity [40]. This capability could be especially interesting for aquaponic producers, as they often face problems in adjusting extreme pH values within the process water, which is a time-consuming and therefore costly process [41]. The optimal pH for aquaponics is 6.5-7 [42].…”

Vermifiltration is a low-energy and low-cost option to reduce the environmental impact of aquaculture. A comparative study was performed for two different stocking densities of the epigeic worm Dendrobaena veneta (Michaelsen, 1890, Annelida: Oligochaeta), which were fed with sediment sludge from African catfish, Clarias gariepinus (Burchell, 1822), recirculation aquaculture systems (RAS). The intensive (I) and extensive (E) systems were stocked with 15 and 10 g of worm/L filter substrate, respectively, and were compared with a control (C) for four weeks. The total weight gain was 9.4–13.5% for (I) and 13.8–19.5% for (E), with low mortality rates of 3.46–5.84% (I) and 3.57–5.19% (E). The temperature inside the vermifilters was slightly higher than that in the control, indicating a favorable milieu for microbial activity. The worms supported the pH buffering capacity in the systems, with the effluent reaching 7.10 ± 0.02 (I) and 7.26 ± 0.04 (E) at the end of the experiment while the pH in the (C) was significantly higher (7.51 ± 0.05). The removal rates were 68.02–98.84% (I), 71.85–98.67% (E), and 72.80–98.68% (C) for the total nitrogen bound (TNb); 82.77–96.64% (I), 81.65–94.84% (E), and 77.79–94.74% (C) for the total organic carbon (TOC); and 50.43–97.51% (I), 50.89–96.84% (E), and 48.23–96.34% (C) for the chemical oxygen demand (COD). By utilizing the sludge as feed, the worms and associated microbiota significantly altered the African catfish sediments, removing organic loads, upgrading the composition, and reducing the possible environmental impacts.

Many plant-derived products are well known to possess therapeutic properties along with minimum side effectsand relatively competitive efficacies as compared to other chemical counterparts/analogs. Herbal drugs are therefore now widely accepted owing to their long-lasting impact. However, the role of cultivation conditions and associated biotic and abiotic parameters are paramount in affecting the yield of phytocompounds among cultivated plants. Moreover, with the increasing burden on cultivable land available for the production of cash crops, medicinal plants require alternative techniques of propagation for meeting commercial demands without adversely affecting their yield of phytocompounds and their therapeutic potential. Regulating the biotic and abiotic parameters using several methods of propagation (viz. vegetative and plant tissue culture) is instrumental in attaining the desired yield in the harvest. The major drawbacks of these techniques are lack of skilled labour and high monetary expense. Alternative techniques, such as hydroponics and aeroponics are pivotal to overcoming these disadvantages. The ‘Hydroponics’ technique involves plant cultivation in a soil-less nutrient medium. This method offers major advantages over the conventional techniques being more economical and independent of seasonal variations besides eliminating the influence of soil-microbe interactions on the development of plants. This technique is under continuous investigation and improvement with recent advances being made in the inter-disciplinary approaches for improving the technique by the addition of IoT and cloud computing along with other conventional techniques such as vertical farming forhydroponic systems and the development of hybrid models.

“…If the level of nutrients needed is not appropriate, the plant can die, or problems occur in its growth. Therefore, it is necessary to monitor and control periodically and continuously to determine the nutritional water conditions directly related to plant growth [6][7][8][9][10][11][12][13][14][15].…”

This paper aims to develop a design for an automatic hydroponic plant nutrient sprinkler. This plant watering device used an Arduino Mega 2560 microcontroller as the interface and an LCD (Liquid Cristal Display) as a display to indicate nutrient levels. The device design deployed a time system set using an Arduino microcontroller and RTC (Real Time Clock) based watering time settings. The development of this automatic nutrient watering device was equipped with a TDS (Total Dissolve Solid) sensor, which reads the value of the nutrient solution content in the water. The LCD displayed monitoring system performance and the relay functions to turn on and off the water pump connected to the hydroponic media watering pipe installation. The benefits of the device can save time and energy. Therefore, the device is more efficient than the manual watering system.
