Which category includes Fertilizer, Pesticides, and Irrigation as examples?

• A. Expenditure
• B. Physical Inputs
• C. Flood Water
• D. Human Inputs

Answer: (D)

In farming systems, inputs are resources added to the farm to boost production. Fertilizer, pesticides, and irrigation are all things that farmers bring in or apply through planning, management, and investment. They are produced, purchased, and operated by people, so they fall under human inputs. Flood water is a natural resource that may influence production but isn’t something a farmer deliberately supplied as part of the farming system in the same controlled way. Expenditure describes the cost aspect rather than the category of input itself, and physical inputs would typically refer to natural resources or equipment not actively managed by people in the same way. So, the best fit is human inputs.
