Integrated Analysis of Resource Capture and Utilization

A set of mathematical identities is derived which relates drymatter production to the availability of above- and below-groundresources, to the efficiency of resource capture, to the efficiencyof resource utilization, to the activity of above- and below-groundorgans and to the partitioning of dry matter in the plant. Thisintegrated analysis can be adapted in various ways accordingto the needs and objectives of the study in hand: it ultimatelyrests upon relatively simple primary data and gives clearlyrelevant derived quantities.
