The use of machinery on the forest site, however, can significantly alter some important soil properties and produce both onsite and offsite impacts on forest and related resources.

Soil compaction is one commonly observed consequence of the use of machinery on forest sites. The Value of Forest Soil Productivity. Sustainable Soil Productivity. Soil productivity is defined as the capacity of soil, in its normal environment, to support plant growth.

Because the effects of soil compaction on forest health vary depending upon the degree of compaction, it would be desirable to add another quantitative measure of soil compaction to the FIA program.

Fuels Management Analyst Suite FMA+Plus 3. Users Guide. Sep 01,  · Infiltration is the flow of water through the soil surface into a porous medium under gravity action and pressure effects. First the water moist soil grains and subsequently the surplus water moves down due to resulting gravitational force.

The present study deals with the effect of compaction state and water content on infiltration property, in particular the saturated hydraulic conductivity. Oct 06,  · Soil compaction and effects on soil properties 1. INTRODUCTION TO COMPACTION EFFECTS OF COMPACTION ON SOIL PROPERTIES 2.

Compaction means pressing of the soil particles close to each other by mechanical methods. Air is expelled from soil. likely due to the machine travel. Reasons for increased compaction at the 25 cm (10 in) depth are not clear. Assuming that machine use increased overall soil compaction, a trend of increased compaction across all depths of the soil at all distances from the track would be expected.

Dec 07,  · Physical properties of forest soils develop under natural conditions by the influence of permanent vegetation over a long period of time.

Physical properties of forest soils may be almost permanent properties unless modified by harvesting operations, shifting cultivation, and forest nightcapcabaret.com by: 8. Several studies investigated soil disturbances caused on skid trails by forest logging.

However, there is still a lack of knowledge about the severity and the distance of disturbances along both sides from the trails. The aims of this study were: i) to investigate the changes in physical and chemical properties of soil along the sides of skidding trails; ii) to measure the effects of soil Cited by: 2.

Sierra Nevada Forest Plan Amendment FEIS Volume 4, Appendix F-3 – Regional Soil Quality Standards Soil strength, infiltration, or other alternative measures of detrimental compaction: Recent scientific studies within the project area also indicate that soil strength measured with a cone.

Clayton, J.L. Prescribed fires were applied to ponderosa pine-incense-cedar and white fir-giant sequoia ecosystems in the southern Sierra Nevada. Aerial and heavy fuels were not affected, but weight, depth, and water-holding capacity of fine fuels were reduced.

Forest floor wettability was altered, and some water repellency was transferred to the soil. Compaction of soil is a process of densification of soil by displacing air from the pores by applying external stress on soil at different moisture content.

Factors Affecting Compaction of Soil – Effect on Different Soil Types. Following the different factors affecting compaction of soil: Water content; Amount of compaction; Types of soil. The dry density achieved depends on the method of compaction. Effect of Compaction on Properties of Soil.

Effect of Compaction on Soil Structure. Soils compacted at a water content less than the optimum generally have a flocculated structure.

Soils compacted at water content more than the optimum usually have a dispersed structure. In large catchments, where floods are often produced by the saturation excess mechanism from lower intensity, longer duration storms, the effect of soil compaction of flood peaks is less obvious.

Overall, soil compaction effects on floods tend to increase with the size of the compacted area, but its spatial arrangement in the landscape does nightcapcabaret.com by: Unfortunately, this book can't be printed from the OpenBook.

The Sierra Nevada subalpine zone occurs between 2,–3, metres (8,–12, ft), and is characterized by an open woodland of several conifer species, including whitebark pine, lodgepole pine, western white pine, mountain hemlock, and Sierra juniper.

The vegetation and ecology is determined by the harsh climate. Impact of Soil Compaction on Soil Physical, Hydraulic Properties and Yields Soil compaction due to cultural operations is an acknowledged problem in the Northern Great Plains (NGP).

Mollisols soils (mostly Typic Agriborolls), common to the region, are easily compacted at. Soil compaction due to mechanized harvesting operations in forests can have profound effects on forest soils and, hence, can have a detrimental effect on subsequent forest regeneration.

We performed a meta-analysis to quantify the effect of soil compaction on height growth, diameter growth, and survival of tree nightcapcabaret.com by: The Sierra series consists of deep to very deep, well drained soils that formed in material weathered from intrusive igneous rocks.

Although simplified patterns of Sierra Nevada geology and soil properties can help describe the regional setting, a tremendous variety of local conditions exists throughout the range.

Soil compaction, also known as soil structure degradation, is the increase of bulk density or decrease in porosity of soil due to externally or internally applied loads. Compaction can adversely affect nearly all physical, chemical and biological properties and functions of soil.

hydraulic conductivity (sometimes called permeability) is the movement of water within soil. Soil hydrologic function is primarily controlled by physical soil properties such as texture, structure, and porosity.

Soil texture—the relative distribution of sand, silt, and clay—is not affected by forest. Jul 01,  · The mild climate at the SJER does not generate soil freezing and thawing, known to effect soil bulk density in colder climates.

The rate at which soils recover from compaction from livestock grazing will likely vary based upon soil properties such as texture and structure, as well as antecedent grazing nightcapcabaret.com by:. Deschutes National Forest, Bend, OR Abstract Data on the effects of livestock grazing on soil nutrient availability are virtually nonexistent for meadow systems.

We measured the effect of livestock grazing on soil, emphasizing soil-solution chemistry, in a Sierra Nevada riparian meadow. Treatments.Published Soil Surveys for Nevada. Current, official soil survey information is on the Web Soil Survey.

These research results have encouraged new intuitions on the effects of soil compaction on forest productivity in different soil types and proved the importance of having site-specific soil quality assessments in forests Cited by: 4.
