Soil microbial activity and abundance data in the rhizosphere and bulk soils of O horizon in the MELNHE study, 2014

The Multiple Element Limitation in Northern Hardwood Ecosystems (MELNHE) project studies N and P acquisition and limitation through a series of nutrient manipulations in northern hardwood forests. This data set includes rhizosphere processes and microbial abundance at the Bartlett Experimental Forest. Samples were collected once, in summer 2014, in the forth year of fertilization with N and P. 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.
