The effects of soil compaction on soil physical properties may alter soil microbial activities and processes, including carbon (C) cycling, and possibly affect agricultural production and environmental degradation. This study investigated the effects of surface soil compaction on soil C mineralization in a claypan soil amended with poultry litter (i.e. turkey excrement mixed with pine shavings ...

Spatial variability in soil properties has long been observed within uniformly managed fields. Understanding the spatial characteristics of soil properties would be helpful in understanding soil–landscape relationships and in the development of site-specific management. The primary objective of this research was to quantify the spatial characteristics of claypan soil properties for a 4-ha agric...

[1] The nature of the snowpack has the potential to strongly influence the patterns of alpine plant productivity and composition by governing soil moisture levels, growing season duration and the thermal regime of alpine soils. This study evaluates these relationships by modeling the interrelationships of snow depth, snow water equivalent (SWE), snow disappearance rate, soil moisture, attribute...

the underlying processes, capacity, and longevity of C pools in agricultural lands. One of our current challenges is to quantify the mechanisms, capacStudies have shown that increases in SOC levels are ity, and longevity of C stabilization in agricultural lands. The objectives directly linked to the return of fresh organic material of this study were to evaluate the long-term (10 yr) role of C ...

Soil quality (SQ) assessment has numerous applications for managing sustainable soil function. Airborne imaging spectroscopy (IS) is an advanced tool for studying natural and artificial materials, in general, and soil properties, in particular. The primary goal of this research was to prove and demonstrate the ability of IS to evaluate soil properties and quality across anthropogenically induce...
