Chapter synopsis: This chapter describes nutrient cycle modelling for nitrogen (N), phosphorus (P), and potassium (K) and is not meant to be a review of existing nutrient models. Most of these existing models were designed to predict the effects of N and P on crop growth response. Given the importance of N in global food production and its impact on the environment, the major emphasis of this chapter has been on N modelling.
