Assessing log extraction related soil disturbance and solutions to protect soil and reduce disturbance of forest ecosystem.
Skid trails are the main routes for wood extraction and also the main source of runoff and sediment production in Forests. This research was conducted in Kuhmiyan forest of Golestan Province to determine infiltration, compaction, strength (resistance to penetration) and moisture content in three treatment including control (in the forest), wheel ruts and middle of skid trail were measured in th...
متن کاملSoil strength response of select soil disturbance classes on a wet pine flat in South Carolina
Harvest operations conducted under conditions of high soil moisture on a wet pine flat in South Carolina resulted in a high degree of soil surface disturbance. Less soil surface disturbance occurred when soil moisture content was lower. Soil strength varied by soil disturbance class in wet harvested locations and highly disturbed areas were associated with low soil strength and elevated levels ...
متن کاملDoes Soil Disturbance Affect Soil Phosphorus Fractions?
Increased turnover of organic matter as a result of soil disturbance (e.g. by soil tillage) is described in principle, but the direct influence of soil disturbance on soil P turnover especially for organic farming systems has not been sufficiently proven. The objective of the study was to evaluate the short term effect of soil disturbance on different soil P fractions in a soil shaking experime...
متن کاملInteractions between soil thermal and hydrological dynamics in the response of Alaska ecosystems to fire disturbance
[1] Soil temperature and moisture are important factors that control many ecosystem processes. However, interactions between soil thermal and hydrological processes are not adequately understood in cold regions, where the frozen soil, fire disturbance, and soil drainage play important roles in controlling interactions among these processes. These interactions were investigated with a new ecosys...
متن کاملResponse of soil invertebrates to disturbance across three resource regions in North Carolina.
We evaluated the potential of soil microarthropods and enchytraeid worms to be useful as bioindicators of soil condition in forest, wetland, and agricultural ecosystems over a range of ecoregions. Selected mesofauna and soil characteristics in soil and litter in relatively undisturbed and disturbed examples of each of three ecosystems within each of three land resource regions were monitored ov...
