Hydroponic Cultivation
This study explains what hydroponic farming is, how to grow using this method, and what materials are needed. It also discusses the advantages and disadvantages of hydroponic farming. Research into hydroponic farming is important because it is a promising solution to many of the challenges facing agriculture today. With a growing world population and limited resources, such as water and arable land, hydroponic farming offers a way to produce food more efficiently and sustainably. It requires less water than traditional farming, and it can be implemented in cities or areas where land is not suitable for farming.
Background
Sustainability and self-sufficiency
As population increases and environmental challenges increase, sustainable farming methods are becoming increasingly important. A key goal is to reduce dependence on imported food and promote self-sufficiency through local production. Hydroponic farming offers a solution where water and nutrient use are optimized, reducing both resource consumption and climate impact.(Dergipark,2018). This approach can help create more robust food systems and ensure the availability of fresh produce in urban areas where land is limited. This is particularly relevant in regions where arable land is limited or where climate change creates precarious conditions for traditional agriculture. Furthermore, hydroponic systems enable year-round cultivation, regardless of external weather conditions, which is crucial for improving food security and reducingtransportation emissionslinked to the import of fruit and vegetables(Dergipark, 2018).
Hydroponic Cultivation and Cultivation Methods
Hydroponic farming is a method in which plants are grown without soil, with the roots instead exposed to a nutrient solution in water. This technique allows for control over the plant's environment, which provides better conditions for growth and harvest. Compared to traditional agriculture, hydroponic farming can reduce water consumption by up to 90%, as the water is recirculated within the system (IOPScience, 2021). Common types of hydroponic systems include:
● Nutrient Film Technique (NFT):A thin film of nutrient solution flows continuously over the plant roots. ● Deep Water Culture (DWC): The roots of the plants are completely submerged in an oxygenated nutrient solution. ● The cultivation raft:A system where the plants float on the water surface, allowing constant access to oxygen and nutrients.
These systems differ in how the nutrient solution is supplied and how the roots are exposed.The cultivation rafthas proven particularly effective for crops such as cucumber, thanks to its simplicity and reliability (ScienceDirect, 2022).
