1. Cost-Optimized NPK Fertilizer Recommendation Using Linear Programming and Mixed Integer Linear Programming for Precision Agriculture

Fertilizer management is one of the most cost-intensive stages of crop production, yet many small and medium-sized brazillian farmers still rely on empirical experience or generalized guidelines to make fertilization decisions. This often results in nutrient imbalances, economic inefficiency, and unnecessary environmental impact. While precision agriculture technologies such as variable-rate application systems and georeferenced soil sampling have advanced considerably, accessible computational... M. Bodanese, R. Sobjak, C.L.
