Soils [Chapter 4.2]

Publications Posted on: October 07, 2015
Soils are crucial for profitable and sustainable biomass feedstock production. They provide nutrients and water, give support for plants, and provide habitat for enormous numbers of biota. There are several systems for soil classification. FAO has provided a generic classification system that was used for a global soil map (Bot et al., 2000).

Rapid response tools and datasets for post-fire modeling: Linking Earth Observations and process-based hydrological models to support post-fire remediation

Publications Posted on: October 05, 2015
Preparation is key to utilizing Earth Observations and process-based models to support post-wildfire mitigation. Post-fire flooding and erosion can pose a serious threat to life, property and municipal water supplies. Increased runoff and sediment delivery due to the loss of surface cover and fire-induced changes in soil properties are of great concern.

Protocols for understanding variability and change in soils

Science Spotlights Posted on: October 05, 2015
Productive forest soils are the underpinning for sustainable forest activities, and monitoring is the key to ensuring productivity has not been altered by land management. The Forest Soil-Disturbance Monitoring Protocol (FSDMP) Toolkit developed by Forest Service scientists helps meet the challenge of developing meaningful soil quality standards that can evaluate the full range of variability found in forest soils. Additionally, the Station sponsored workshops in every Forest Service Region to outline the protocol and conduct field training sessions.

Effects of fuels reduction treatments on the soil temperature, heat-flux, water content, and CO2 at Manitou Experimental Forest

Datasets Posted on: August 27, 2015
From 2001 to 2006 data were collected to measure the effects of different fuels reduction treatments on the soils of the Manitou Experimental Forest, Colorado. The data includes profiles of temperature, heat-flux, water content, and CO2 at different depths in the soil and a horizontal transect surface radiation . Fuels reduction treatments included slash-piles, broadcast/lop-and-scatter areas, chipped areas, and control areas.

Data product for "Effects of water and nitrogen availability on nitrogen contribution by the legume, Lupinus argenteus Pursh"

Datasets Posted on: August 27, 2015
We conducted a greenhouse experiment to examine the separate and interacting effects of water and nitrogen (N) availability on biomass production, tissue N concentration, nodulation, nodule activity, and rhizodeposition of Lupinus argenteus (Pursh), a legume native to sagebrush steppe. Plants were grown in a replicated, randomized block design with three levels of water and four levels of N.

The nutrient content of Rocky Mountain vegetation: A handbook for estimating nutrients lost through harvest and burning

Documents and Media Posted on: August 20, 2015
Samples of forest components that are normally burned or removed during harvest were collected at the Coram Experimental Forest and the Lubrecht Experimental Forest and analyzed for elemental content.Document Type: White Papers

Using biochar to improve soil quality on decommissioned roads

Science Spotlights Posted on: August 20, 2015
Biochar is created from excess woody biomass that would normally be burned. Biochar use on forest sites can (1) sequester carbon, (2) improve soil moisture conditions, (3) decrease soil bulk density, and (4) improve native vegetation success. These four attributes combine to improve the success of soil restoration activities, particularly on drought-prone sites. 

Preliminary soil-site studies in the western white pine type

Publications Posted on: August 14, 2015
A guide for estimating site quality on bare, cut-over, or burned-over lands in the western white pine type is needed for planning the management of these lands. On many areas trees may be entirely lacking or an insufficient number in the proper crown classes remain on which reliable site index determinations can be based.

Preliminary report on soil-rootlet relationships to pole blight of western white pine

Publications Posted on: August 14, 2015
Results of a coordinated soil-rootlet mortality study in 1954 indicate that the severity of the pole blight disease of western white pine (Pinus monticola Dougl.) is significantly correlated with certain physical soil characteristics and rootlet mortality. The finding of this relationship does not necessarily imply that these factors are the cause of pole blight.

Fall sowing and delayed germination of western white pine seed

Publications Posted on: August 06, 2015
Experiments to determine the best time to sow seed of western white pine (Pinus monticola) have been under way in the northern Rocky Mountain region since 1912, partly in northern Idaho at the Priest River Forest Experiment Station, but mainly at the Savenac nursery on the Lolo National Forest in western Montana.
