Agriculture has been growing more and more due to the demand for food, fiber and biofuels and advanced technological resources, elements that support the optimization of intensive production. It can be noted that along with this development comes the concern with the quantity and destination of tailings produced in the livestock activity. With this, the producer must promote an adequate planning that helps him in his decision-making. Now, in Modeling and Mathematical Programming, we have important tools to help rural producers. Therefore, this research aimed to develop a mathematical model aimed at linear programming, developed in the LINGO 4.0 software that would subsidize the production planning process and assist in decision-making activities, providing the optimization of agriculture by considering two conflicting factors: the increase in productivity, giving rise to greater profitability and the adjustment of the Agricultural Production Unit (UPA) to current environmental legislation. For this, a pilot property in the municipality of Santa Helena located in the west of Paraná was selected. At first, visits and interviews were carried out with the rural producer of the chosen unit to obtain the interpretation of agricultural production and characterization of the relevant elements to obtain the results. After data collection, analysis was performed and a mathematical model developed to optimize an agricultural production unit characterized by crop-livestock integration. The main result of this research was the maximization of the annual economic result (REA), which proved to be more effective than the simulation of the monthly economic result (REM), with regard to the use of the useful area surface and the waste generated in the activity farming. The total reuse of swine effluents, which are the most impactful, in the UPA itself was obtained; on the other hand, poultry waste, due to its ease of handling, high added economic value and easy-to-apply logistics, the model suggested commercialization as organic fertilizer. |
