The correct answer is:

planters (D)

Explanation:

The key statement in the question is that Andrew wants to apply pesticides and fertilizers to all his crops across his large land. The most effective way of doing this is by using a planter to apply both the fertilizer and the pesticide as the planting occurs. This will ensure that the fertilizers and pesticides are applied directly to the crops and not scattered on the vast land.
