High-density farming, also known as intensive farming, is an agricultural practice designed to maximize the amount of crop yield produced per unit area of land. This method employs a combination of advanced techniques, technologies, and scientific principles to cultivate crops more efficiently. The goal is to produce the highest possible yield from the smallest possible space, often through the use of vertical farming, hydroponics, aeroponics, and other innovative systems.
