Abstract:

Leaves of eight species (see 'taxonomic extent') were sampled from 71 plots on site A of the BEF China Main Experiment at Xingangshan, Dexing County, PR of China. Per plot 1 to 16 individuals were sampled and samples were analyzed for P, C and N contents. This dataset is part of a master thesis (see below) that aimed at investigating whether tree diversity can overcome the effects of nutrient limitation on forest growth in young afforested tree communities. Therefore it is in close interjunction with the datasets on soil nutrient status in the respective sampling sites (http://china.befdata.biow.uni-leipzig.de/datasets/331; http://china.befdata.biow.uni-leipzig.de/datasets/561). In cases where little material was available, emphasis was put on the measurement of P contents.

Design:

Leaves were dried at 40°C and finely ground. Carbon and Nitrogen was measured after dry combustion with a Elemental Analyzer truspec, Leco, St. Joseph, MI, USA; Phosphorus was measured after digestion with concentrated nitric acid with the molydenum-blue method (Murphy and Riley, 1962)

Spatial extent:

The experimental study plot Site A is located near the village Xingangshan in Dexing County near to Jiangxi province and was planted spring 2009.

Temporal extent:

Leaves were sampled 2013

Taxonomic extent:

Castanea henryi Castanopsis sclerophylla Quercus serrata Choreospondias axillaris Nyssa sinensis Liquidambar formosana Sapindus saponaria Triardica sebifera

Location

Definition:

This column defines the location where the sample has been taken. It ocnsists of the following information: Site-Plot.XX_YY Where XX is the X position in the planting design of BEF China; YY can be: the YY position in the BEF-China planting design OR a short form of the species growing in this position (if known to the sampling person). If one is interested in the species identity of the respective individual, please refer to the species in the XXYY position given in the census data of Site A in 2013 (http://china.befdata.biow.uni-leipzig.de/datasets/473) or (if shown) to the short species identity in this location identifyer.
