Aboveground Net Primary Production in Row Crop Agriculture
This data set contains information about above ground net primary productivitiy (ANPP) for all main site cropping systems as well as for the forested sites added in 1993. Main site cropping systems include all treatments as described in the data set descriptor for the main cropping system study . ANPP is measured as peak biomass for a given cropping system; in some systems with complex communities peaks occur at different times of year and measurements are taken at multiple times as described in the ANPP protocol.
