Soil Bulk Density

Only a few bulk density samples were taken to characterize the Resource Gradient. Soil cores taken using ‘root corer’ – dimensions: 14.0 cm height x 7.9 cm diameter
On 08/21/2007 soil samples weighed using metal tins – sample dried in oven at 60 Celsius for 24 hours

This datatable is part of the Resource Gradient Experiment dataset. This study provides a gradient of 9 different rates of nitrogen fertilization under rainfed and irrigated conditions. Irrigation began in 2003. Corn was grown from 2000-2005 and subsequently the crop rotation (wheat, corn, soybean) followed the crop of the LTER main site. Nitrogen applications differ by crop after 2007.

The experiment was moved to its current location on the LTER main site in 2005. The experiment location/history are explained here.

Plots are 5×30 m arranged in each of 4 replicate blocks .

Crop yields, nitrous oxide and soil temperature, moisture and nitrogen data are available for this study.
