One of the modern ways to achieve this is through precision farming. Precision farming allows farmers to move away from blanket fertiliser application to applying fertiliser to a specific infertile area. Precision farming also allows farmers to compare harvest information and to identify non- fertile spots in their fields. This enables farmers to investigate the causes of infertile soil on their farms. 4.1.1 Identify THREE ways by which precision farming results in optimum use of resources from the scenario.
