| Abstract: | Under this approach, the nutrient requirements,instead of being fixed values as in traditional linear programming, are considered targets that the farmer aspires to, although they may or may not be achieved. A penalty system is grafted onto the model, which makes the lower and upper level of nutrients more flexible and realistic. An example is shown applied to a problem based on real data to analyze the optimum combination to fertilizers for sugar beet. In general, the approach proposed permits the farmer to establish trade-offs between the different nutrient requirements and the cost of the combination. |
