11. Soilless Cultivation of Plants for Phytoremediation

Thisi review examines the possibility of soilless cultivation systems as a means of overcoming resource scarcity in many places of the world, such as good soil and clean water. The conventional usage of arable land is becoming more difficult, especially in light of climate change. Soilless farming systems not only allow you to save water and grow plants without soil, but they also allow you to grow food in urban locations, such as residential rooftops, near to where people dine. The review compares the uses of soilless farming systems to those of conventional farming.i It examines economic viability, sustainability, and current events in this field. The review discusses three major soilless farming systems: hydroponics, aquaponics, and vertical farming. In terms of how they affect the environment, these systems are distinguished from one another and compared to conventional cultivation techniques to the maximum extent possible. In order to set the framework for future research and practical applications, the review compares published data on the yield of hydroponic cultivation systems with soil-based cultivation methods. This research provides an overview of how profitable each strategy is. The review also compares the sustainability of the most major neutral substrates used in hydroponics to highlight their environmental effects and assist future projects in selecting the appropriate substrate. The review examines the major soilless cultivation systems and discusses the difficulties and improvements to current approaches. It seeks to provide a comprehensive image of soilless farming systems so that further research may be conducted and they can be deployed in the actual world in the future.
