The ingrowth core method is widely used to assess fine root(diameter < 2mm)production but has many inherent deficiencies.In this study,we modified this method by adopting mini ingrowth cores(diameter 1.2cm),extending sample intervals to a growing season,and developing new models to quantify the concurrent production,mortality and decomposition,and applied them to a secondary Mongolian oak(Quercus mongolica)forest.
