Phenology 2013-Present

Phenology recorded from 2013 to present. Data from 2010 to 2012 are in another data table since the protocol changed. Phenological data gives a record of the timing of major life events in the GLBRC crops.

This datatable is part of the GLBRC Phenology dataset. Phenology data used to characterize the growth of biofuel crops are collated here.
