Cultivating terrestrial plants within aerated nutrient solutions without soil is known as___________________?
Show answer Hide answer
Answer: D. Hydroponics
Explanation
Hydroponics is the specialized agricultural technique of growing terrestrial plants in aerated nutrient solutions. This soil-less method delivers water and dissolved mineral ions directly to plant root systems. Cultivating crops this way allows precise control over the plant root environment and nutrition. Hydroponic systems can be configured in various designs such as deep water culture or drip systems. Plants supported by inert media like perlite or rockwool anchor themselves while absorbing nutrients. Greenhouse growers utilize this technology to produce high-value vegetable crops year-round efficiently.
Urban agriculture leverages hydroponics to grow fresh produce in limited spaces without arable soil. Water conservation is significantly improved because hydroponic systems recycle nutrient solutions continuously. Arid regions with poor soil quality depend on hydroponics to achieve sustainable local food production. Nutrient film technique is a specific subtype of hydroponics rather than the overarching general term. Hydrology is the scientific study of the movement and distribution of water across Earth. Hydrants are mechanical fire protection water valves rather than a plant cultivation methodology.
