What is one essential tool used for soil tillage?

A plow is an essential tool used for soil tillage because its primary function is to break up and turn over the soil, making it suitable for planting crops. Tillage serves several critical purposes in agriculture: it aerates the soil, incorporates organic matter, and prepares seedbeds by creating an ideal environment for seeds to germinate and grow.

While a tractor can provide the necessary power to pull the plow, it is not specifically designed for soil tillage on its own. A seed drill is utilized for planting seeds at the correct depth and spacing but does not prepare the soil in the same way a plow does. A harvester, on the other hand, is used for collecting mature crops and plays no role in soil preparation. Thus, the plow is uniquely suited to the task of tilling soil, making it a critical tool in agricultural practices.
