The correct answer is: To plant seeds at the correct depth and spacing in the soil

The purpose of a seed drill is to plant seeds at the correct depth and spacing in the soil. This method of sowing ensures that each seed is placed in an optimal environment for germination, which enhances crop establishment and increases overall yields. By using a seed drill, farmers can achieve uniform planting, which is essential for effective competition among plants for sunlight, nutrients, and water. This precision not only improves germination rates but also facilitates better management of the crop throughout its growth cycle. Additionally, employing a seed drill allows for efficient use of resources, such as seed and soil moisture, and helps reduce the amount of seed wasted compared to broadcasting methods. Overall, the use of a seed drill is a vital practice in modern agriculture that contributes significantly to the efficiency and productivity of farming operations.
