Mathematical models are used to extend research findings beyond the boundary conditions of the original experiment. Most modeling approaches are based on visualizing and developing conceptual diagrams, conducting focused experiments, creating the mathematics, and testing the model. Each modeling component leads to a better understanding of the problem. This chapter discusses each of these components as well as provides (i) a discussion on how different conceptual models can result in different experimental treatments and possible interpretations, (ii) examples on how to calculate and use rate constants to solve agricultural problems, and (iii) examples on how to calculate the economic optimum fertilizer rate.
