Which of the following sources of farm power will assist in the tillage of more land per unit time?
Answer Details
Among the given sources of farm power, machines are the most efficient for tillage of more land per unit time. Machines are designed to perform specific tasks, and can operate for long periods of time with minimal breaks. This allows farmers to cover large areas of land quickly and efficiently.
Man and animal power are limited by physical endurance, strength and ability to work only for a certain period before needing rest or food. This limits the amount of land that can be tilled in a given amount of time.
Wind power can be harnessed for some farm activities such as milling, but it is not practical for tillage, as the wind is not reliable or constant enough to power large machines.
In summary, while all four sources of farm power can be used for tillage, machines are the most efficient for covering more land per unit time, due to their power, reliability, and ability to operate for long periods with minimal breaks.
