“…Plants in a hydroponic system are supplied via the same nutrient solution, which means that plants within the system should have the same requirements. In addition, waterborne diseases can easily spread from one plant to another [84]. Great care is required in controlling plant health.…”

Resources such as fertile soil and clean water are already limited in many parts of the world. Additionally, the conventional use of arable land is becoming increasingly difficult, which is further exacerbated by climate change. Soilless cultivation systems do not only offer the opportunity to save water and cultivate without soil but also the chance to open up urban areas such as residential rooftops for food production in close proximity to consumers. In this review, applications of soilless farming systems are identified and compared to conventional agriculture. Furthermore, aspects of economic viability, sustainability and current developments are investigated. An insight into the most important soilless farming systems—hydroponics, aquaponics and vertical farming—is provided. The systems are then differentiated from each other and, as far as possible, evaluated in terms of their environmental impact and compared with conventional cultivation methods. Comparing published data analyzing the yield of hydroponic cultivation systems in comparison to soil-based cultivation methods enables a basic overview of the profitability of both methods and, thus, lays the foundation for future research and practical applications. The most important inert substrates for hydroponic applications are presented, and their degree of sustainability is compared in order to emphasize environmental impacts and affect substrate selections of future projects. Based on an assessment of the most important soilless cultivation systems, the challenges and developments of current techniques are highlighted and discussed.

“…Similarly, our studies have demonstrated and validated that the pesticide residues in two leafy vegetables (lettuce and celery) and two fruit vegetables (tomato and cucumber) from hydroponic cultivation were significantly lower than in those from conventional cultivation. Although hydroponic cultivation is an advantageous technique, the application of pesticides is inevitable due to the invasion of pathogens and pests outside the hydroponic system and water-borne diseases that can spread quickly from one plant to another [25]. Hydroponic vegetables are considered organic food.…”

Hydroponic cultivation of fresh produce is gaining popularity worldwide, but few studies have provided a comparative assessment of hydroponic and conventional soil-based vegetables. In this study, we analyzed a series of hazardous chemicals, including 120 pesticides, 18 phthalates (PAEs), and 2 heavy metals (lead and cadmium) in four vegetable commodities (lettuces, celeries, tomatoes, and cucumbers) from hydroponic and conventional soil-based cultivation. Our study showed that at least one pesticide was present in 84% of the conventionally grown samples, whereas only 30% of the hydroponic samples contained detectable pesticide residues. Regarding the total PAE concentrations, there was no significant difference between conventional and hydroponic vegetables. The lead and cadmium residues in conventionally cultivated vegetables were significantly higher than in those produced from hydroponic cultivation. Lead is the primary heavy metal pollutant across all vegetable samples. The hazard index (HI) values of the hydroponic and conventional vegetables were 0.22 and 0.64, respectively. Since both values are below one, the exposure to these hazardous chemicals through consumption of the studied vegetables may not pose a significant health risk. The HI values also suggested that the health risks of eating hydroponic vegetables are lower than for conventional soil-based vegetables.

“…It is a method which is more complex and involved than traditional farming. Plant in a hydroponics system is sharing the exact same nutrient and water borne diseases can easily spread from one plant to another (Ikeda et al, 2002) [9] . Hot weather and limited oxygenation can limit production and may result in crop loss.…”

Many challenges have come to the limelight in recent years due to a rapid increase in the world population. One of these challenges is the reduction of the per capita land available for soil-based agriculture, leading to other agricultural and environmental problems. Under these critical circumstances, it became necessary to develop advanced technologies and techniques to withstand the current situation. While several studies have been carried out on soil and in vitro plant cultivation, few of these are based on soilless crops. Soilless agriculture is a new promising method for improving cultivation of different cash crops. Apart from the reservation and restoration of cultivation land, soilless farming, especially close-loop method, has numerous advantages: it uses recycled fixed quantities of water, saves 85-90% of irrigation water, can be implemented in unfavourable areas for ordinary farming, nearly zero contamination of the atmosphere, better yield than traditional farming. Therefore improved space and water management methods of food production under soilless cultivation have shown some promising results throughout the world.
