Abstract

Zachary Brecheisen, Dan Richter, Mac Callaham, Will Cook, and Paul Heine have sampled and analyzed soils from 15 locations in the Calhoun CZO. Sampling is underway, though all soil texture samples have been collected and are in process. The first quarterly invertebrate sampling occurred in September 2015. Bulk density, Ksat, and water stable aggregate sampling and analyses will occur in 2016. This work targets 3 different land forms: flat uplands, mid-slopes, and steeper slopes in 3 different land use comparisons. The land uses consist of 3 reference hardwood forests minimally degraded by human activity, 3 old-field secondary succession pine forests >60 yo, and 1 pseudo-replicated agricultural plot which has been, to the best of our knowledge, continually cultivated from the 1930’s at the latest. The goal of this sampling is to identify physical anthropogenic signals in the upper meters in the soil profile of cultivated lands and to evaluate their persistence or lack thereof in old-field pine forests relative to reference hardwoods.

comments	Properties analyzed/measured include water stable aggregates, texture, bulk density, Ksat, soil macroinvertebrates. Biological/invertebrate samples are collected from the litter and upper 30cm of the soil profile in a 30x30cm cube. Water stable aggregates, bulk density, and Ksat will be derived for at least the upper 2m of the profile. Soil texture is calculated from the surface to 5m depth. All of these analyses are performed at the same 15 locations as the gas sampling wells.
