Forest Soil Productivity
" Minnesota' s forest soils are a fundamental resource on which rests the ability of our forests to provide a wide variety of benefits." Jaakko Pöyry 1992 The goal of these guidelines is to maintain the productive capacity of forest soils in Minnesota. A decrease in soil productivity could affect the level of timber harvesting the forest can sustain, as well as other forest values, such ...

The Complete Guide to Forestry Mulching | GPH Grading
Instead, with forestry mulching, a single machine is used to cut, grind, and clear vegetative growth and saplings, leaving behind a shredded blanket of mulch. This protective layer of organic material is left to break down and be reintroduced into the soil, making it richer and more fertile. The biodegradable toplayer (mulch) becomes a natural protective barrier over the soil that stabilizes ...

Compaction of forest soils with heavy logging machinery ...
Soil compaction is widespread but tends to be most prevalent where heavy machinery is used in landfill sites, agriculture and forestry. Three forest sites strongly disturbed by heavy logging machinery were chosen to test the physical effects of different levels of compaction on soil bacterial community structure and soil functions. Community analysis comprised microbial biomass C and TRFLP ...
Machinery's impact on forest soil porosity — ISTVS
· Abstract: The heavy machines used in forest operations not only cause reduction of the total amount of soil pores but also drastically modify their size distribution. The effects in these terms of repeated passages of a tracked skidder and a wheeled one of quite similar size were evaluated in a forest of central Italy. In particular, we focused on macroaggregates, the ones of centimetric ...
Changes of carbon dioxide concentration in soils caused by ...
The primary objective of this paper was to determine the impact of forestry machine traffic on subsurface soil CO 2 concentration. We measured CO 2 concentration in the areas undisturbed by machinery and in the ruts in skid trails in eight forest stands. The measurements were performed using a Vaisala MI 70 meter. The results confirmed significant differences in gas concentrations between the ...
(PDF) Compaction of forest soils with heavy logging machinery
Heavy machinery in different farm forestry programs produces shear stress on the soil surface (Edlund et al., 2013; Naghdi et al., 2017), and trampling from domestic animals (Ferrara et al., 2015 ...

MachineryInduced Damage to Soil and Remaining Forest ...
Damage to forest soil can be characterised mainly by rutting, soil displacement and soil compaction caused by passage of machinery or load [12,13]. Soil compaction is in fact one of the main causes of soil degradation because it reduces soil production capacity, and leads to degradation processes, such as erosion or floods [ 13 ].
Physical recovery of forest soil after compaction by heavy ...
Abstract Soil compaction, which results from the skidding of heavy machines used in forest operations, can seriously damage forest productivity. Indeed, it alters soil structure, disturbs its physical features and consequently affects gas exchange and biological activities. The impact of compaction on soil health has been widely studied, but less is known about the recovery of soil properties ...
Stress Distribution under Forestry Machinery and ...
· Stress impacts of forestry machinery exceed soil stability and cause soil degradation. Special forestry machinery is able to reduce stress impacts significantly. Only weight reduction and cleat tracks combined lead to stable soil conditions in topsoil. The major principal stress (σ 1) of modern wheels and cleattrack forestry machinery was evaluated regarding changes in soil strength during ...
