To compensate for no explicit representation of nutrient cycles and other management options that may affect productivity (e.g., pest control, soil preparation), LPJmL can account for management intensity levels, and can be calibrated to reproduce actual FAO yields ([[Fader et al., 2010]]). However, given the complex interaction with the [[Land-use allocation]] model , LPJmL simulates crop yields without nutrient constraints (potential water-limited yields) in the link with IMAGE. Actual yields are derived by IMAGE by combining potential yields from LPJmL with a management factor that can change over time (see Component [[Agricultural economy]]). As input for the IMAGE land-use components (Component [[Agriculture and land use]]), LPJmL calculates productivity of each crop in each grid cell under rain-fed and irrigated conditions. | To compensate for no explicit representation of nutrient cycles and other management options that may affect productivity (e.g., pest control, soil preparation), LPJmL can account for management intensity levels, and can be calibrated to reproduce actual FAO yields ([[Fader et al., 2010]]).

The crop and grassland component is embedded in the dynamic global vegetation, agriculture and water balance model LPJmL, and thus carbon and water dynamics (Components [[Carbon cycle and natural vegetation]] and [[Water]], respectively) consistently account for dynamics in agricultural productivity and land-use change. | The crop and grassland component is embedded in the dynamic global [[Carbon, vegetation, agriculture and water|vegetation, agriculture and water balance model]] LPJmL, and thus carbon and water dynamics (Components [[Carbon cycle and natural vegetation]] and [[Water]], respectively) consistently account for dynamics in agricultural productivity and land-use change. | ||
