Alternate Identifier:

DOI PLACE HOLDER

Abstract:

Root biomass was measured from root cores taken in New Hampshire at the Bartlett Experimental Forest, Hubbard Brook Experimental Forest, and Jeffers Brook as part of the Multiple Element Limitation in Northern Hardwood Ecosystems (MELNHE) study. Pretreatment, in 2008 roots were collected at JB and HB and in 2010 roots from all BEF stands except C3. Stands were sampled post-treatment as follows: C2 in 2014 and 2018; C1, C4, C6, C7, and C9 in 2015; and C3, C5, C8, HB, and JB in 2016. Roots were picked, sorted by size and vitality, oven-dried and weighed to determine live fine root biomass in response to NxP fertilization.

Additional detail on the MELNHE project, including a datatable of site descriptions and a pdf file with the project description and diagram of plot configuration can be found in this data package: https://portal.edirepository.org/nis/mapbrowse?scope=knb-lter-hbr&identifier=344

These data were gathered as part of the Hubbard Brook Ecosystem Study (HBES). The HBES is a collaborative effort at the Hubbard Brook Experimental Forest, which is operated and maintained by the USDA Forest Service, Northern Research Station.

Description:

This study took place in all 13 stands in the Multiple Element Limitation in Northeast Hardwood Ecosystems (MELNHE) at Bartlett Experimental Forest (BEF), Hubbard Brook Experimental Forest (HB) and Jeffers Brook (JB) in New Hampshire.

More information on this project design can be found in the following file:

Yanai, R.D., M. Fisk, and T.J. Fahey. 2022. Multiple Element Limitation in Northeast Hardwood Ecosystems (MELNHE): Project description, plot characteristics and design ver 1. Environmental Data Initiative. https://doi.org/10.6073/pasta/bcfc628d26e78b3dff648c34a33da1a3

Pretreatment, in 2008 roots were collected at JB and HB and in 2010 roots from all BEF stands except C3 were collected. Stands were sampled post-treatment as follows: C2 in 2014 and 2018; C1, C4, C6, C7, and C9 in 2015; and C3, C5, C8, HB, and JB in 2016.

We hammered 5-cm PVC pipes 25-30 cm into the ground near each soil respiration collar in each plot. Soil cores were divided into 0-10 cm and 10-30 cm increments. Live roots of 0-1 mm and 1-5 mm diameter from each depth range were picked out of the soil and sorted by size. Roots were rinsed of excess soil, dried at 60 °C and then weighed.
