In modern agriculture systems fertilizers are applied to provide the plants with sufficient nutrients to obtain an optimal yield.
If no fertilizer or manure is applied then the yield results are a lot lower. Looking at the total production costs of a crop will probably show that the costs of fertilizers are in the top 3 of all costs items. Over application of fertilizers will result in wastage of money and can also have negative effects on the environment, for example pollution of ground water.
