What does vertical farming involve?

• A. Growing crops in open fields
• B. Utilizing controlled-environment agriculture in stacked layers
• C. Farming only in rural areas
• D. A focus on soil-less gardening in direct sunlight

Answer: (B)

Vertical farming involves utilizing controlled-environment agriculture in stacked layers, which allows for the cultivation of crops in a way that maximizes space and efficiency. This method often incorporates technology such as hydroponics or aeroponics and is designed to produce food in urban environments where land is limited. The controlled environment helps to optimize plant growth by regulating factors such as temperature, humidity, light, and nutrients.

This approach contrasts with traditional farming methods that rely on open fields, as well as soil-based gardens that depend on direct sunlight and require more land. Vertical farming is particularly beneficial in urban settings where space is at a premium, making it a sustainable and innovative solution to the challenges of urban food production.
