Advanced technology in horticulture equipment includes?

• A. Shovel, rake, and wheelbarrow
• B. Tractor, weed-wacker, and lawn mower
• C. Hydroponic nutrient monitor
• D. Computerized greenhouse systems, and ebb and flow benching

Answer: (C)

Modern horticulture relies on sensor-based technology to optimize plant nutrition and growing conditions. A hydroponic nutrient monitor exemplifies this advanced equipment because it continuously measures nutrient levels, pH, and often conductivity in the solution, and can be linked to controllers that adjust feeds automatically. This kind of device brings precision and automation to nutrient management, which is at the heart of high-tech growing systems like hydroponics.

The other options reflect more traditional or general equipment. Shovels, rakes, and wheelbarrows are manual tools and not technology-driven. A tractor, weed-wacker, and lawn mower are productive machines but not focused on advanced nutrient control. While computerized greenhouse systems and ebb-and-flow benches are indeed sophisticated, the nutrient monitor specifically demonstrates automated, measurement-based management of the essential inputs that plants need, making it the clearest example of advanced technology in horticulture equipment.
