What does the Law of Diminishing Returns state regarding the addition of input in production?

The Law of Diminishing Returns explains that when you keep adding more of one input in production, like labor or fertilizer, while keeping other inputs constant, the extra output you get from each additional unit will eventually start to decrease. For example, if a farmer adds more workers to a field but doesn’t increase the size of the field, each new worker will contribute less to the overall harvest than the previous one. Initially, adding workers might greatly increase the crop yield, but after a certain point, those new workers will crowd each other and not be able to work as efficiently. This means that while you can still get some benefit from adding more input, the added benefit will be less and less over time. Understanding this law helps businesses and farmers make better decisions about how much input to use for maximum efficiency.
