Improving modeling of nutrient cycles in crop cultivation

Improving modeling of nutrient cycles in crop cultivationThis 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.
