Soil pH — Resource Gradient Experiment

Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Soil pH of surface (0-25 cm) soils collected periodically in the fall to monitor the need for soil liming.

This datatable is part of the Resource Gradient Experiment dataset. This dataset contains the agronomic yields and soil properties of the LTER Resource Gradient Experiment, which applies nine different rates of nitrogen fertilization (F1-F9) to annual row crops under rainfed (since 1999) and irrigated (since 2003) conditions. Since 2006, row crops have followed the same rotation as the LTER Main Cropping System Experiment (MCSE; corn-soybean-wheat); continuous corn was grown from 1999-2005. Nitrogen fertilization rates differ by crop (since 2008) and are given on the plot map.

The experiment moved to its current location in the LTER Main Site in 2005; previous experimental designs and locations are given here
