Soil organic carbon content and composition of 130-year crop, pasture and forest land-use managements
Autor: Thomas E. Reedy, David T. Lewis, Dean A. Martens
Publikováno v: Global Change Biology. 10:65-78
Conversion of former agricultural land to grassland and forest ecosystems is a suggested option for mitigation of increased atmospheric CO2. A Sharpsburg prairie loess soil (fine, smectitic, mesic Typic Argiudoll) provided treatments to study the imp

Numerical taxonomy of soils using spectral information of overlying range vegetation
Autor: David T. Lewis, Scott A. Samson
Publikováno v: Geoderma. 50:1-11
Unique spectral “signatures” of rangeland vegetation were used to identify and delineate soil map units associated with a hydrosequence. Single-linkage cluster analysis was employed to obtain relatively objective and “natural” groupings of sp

Mineralogical implications of high ratios of 1500 kPa water content to percent measured clay for two soils of western Nebraska
Autor: David T. Lewis, N.B. Stolpe
Publikováno v: Geoderma. 47:1-16
Tripp (coarse-silty, mixed, mesic Aridic Haplustolls), and Mitchell (coarse-silty, mixed (calcareous), mesic Ustic Torriorthents) soils of western Nebraska have frequently exhibited high ratios of 1500 kPa water content to percent measured clay. Both

Publikováno v: New Library World. 75:93-102

Use of Satellite Imagery to Delineate Soil Associations in the Sand Hills Region of Nebraska
Autor: Paul M. Seevers, James V. Drew, David T. Lewis
Publikováno v: Soil Science Society of America Journal. 39:330-335
Published soil association maps of counties within the Sand Hills region of Nebraska were used to establish relationships between satellite imagery and soil associations mapped by conventional methods. Soils formed in the eolian sand of this region r
