“…In addition to the difficulty of managing the nutrients, there is also the wastewater that hydroponics generate [14]. Because there is no simple inexpensive method for home gardeners to determine the individual nutrients in the solution, after or during the growing process, the water is often discarded and a new solution is mixed.…”

Development and Testing of an IoT Spectroscopic Nutrient Monitoring System for Use in Micro Indoor Smart Hydroponics

Nutrient monitoring in Micro Indoor Smart Hydroponics (MISH) relies on measuring electrical conductivity or total dissolved solids to determine the amount of nutrients in a hydroponic solution. Neither method can distinguish concentrations of individual nutrients. This study presents the development and testing of a novel spectroscopic sensor system to monitor nitrogen changes in nutrient solutions for MISH systems. The design phase determined that using an inexpensive AS7265x Internet of Thing (IoT) sensor in a transflective spectroscopic application could effectively detect small fluctuations in nitrogen concentraation. Next, a novel transflective sensor apparatus was designed and constructed for use in a MISH system experiment, growing lettuce over 30 days. Two solution tanks of different sizes, 80 L and 40 L, were used in the deployment of the system. Samples from each tank were analyzed for nitrogen concentration in a laboratory, and multilinear regression was used to predict the nitrogen concentrations using the AS7265x 18 spectral channels recorded in the sensor system. Significant results were found for both tanks with an R2 of 0.904 and 0.911 for the 80 and 40 L tanks, respectively. However, while the use of all wavelengths produced an accurate model, none of the individual wavelengths were indicative on their own. These findings indicate that the novel system presented in this study successfully and accurately monitors changes in nitrogen concentrations for MISH systems, using low cost IoT sensors.

“…Plant varieties bred or modified for compact growth, high yields, and improved water and nutrient use efficiency in aeroponic/hydroponic systems would be beneficial, and might be coupled with engineering solutions to increase water and nutrient recycling. [112][113][114] Furthermore, portable, and spaceefficient CEA units designed using SpaceAg technologies could be used as emergency food production units on Earth. These units can be deployed in disaster-hit areas to ensure a continuous supply of fresh produce until traditional agriculture can be re-established.…”

Planned missions to Mars and the moon stress the urgency of developing self‐sustaining food production systems for crewed, long‐term, space exploration. Here we discuss space agriculture (SpaceAg) as a sustainable complete life support system for prolonged space travel and surface missions. The unique challenges and considerations for cultivating crops in space, where radiation, gravity, atmosphere and temperature differ from Earth, are presented. We discuss the selection of suitable crops and approaches to optimise growth traits for the ideal plant form, including the potential of genetic engineering to enhance yield and nutritional content. Plants can serve multiple roles, from providing nutritious foods and wellbeing to acting as biofactories for essential pharmaceuticals. The need for robust and efficient controlled environment agriculture (CEA) systems that are integral to life support is explored. Finally, we discuss promising solutions for sustainable agriculture in controlled environments on Earth, based on SpaceAg research and innovation.

“…Hydroponically grown plants with automatic processing can be used smartly to decrease crops' growth period and save resources such as workforce, water, and fertilizers, thus increasing their productivity (Sanjay and Balasaheb 2021). The buildup of inhibitory allelochemicals that reduce yield and quality due to the autotoxicity phenomenon is a significant concern for recycled hydroponics (Asaduzzaman et al 2022).…”

Hydroponics and aquaponics are emergent agricultural techniques that offer several environmental solutions. It is anticipated that the hydroponic systems will result in a more significant profit from selling vegetables and other plants. The use of new technologies, such as hydroponics and aquaponics, has been demonstrated to increase the number of plants that can be grown. The recirculatory aquaculture system makes it possible to multiply fish production while consuming fewer resources. Essential factors of this technology include higher yield, safety, and water management. In addition, the scope of potential future research in hydroponics and aquaponics has been discussed. Furthermore, the paper identifies and discusses the various applications of hydroponics and aquaponics in agriculture.
