“…Except for TST area, there was no significant difference between traffic classes. A great deal of research indicated that a higher increment of soil bulk density arises after the third pass and the subsequent passes have a lower effect (Horn et al 2004;Ampoorter et al 2007). The lower bulk density value for TST traffic class of farm tractor in comparison with the other classes depended on the lightweight of the tractor and weight distribution through more wheels (6 wheels).…”

“…In that regard, machine passes have an important influence on soil structural characteristics, soil aeration, soil water balance, and may, therefore, considerably affect soil organisms and root development (Ampoorter et al 2007). Concerns about soil degradation after forest operations and its impact on the future stand have increased during recent decades (Jansson, Johansson 1998).…”

Physical properties of soil can be affected by machines that are used for skidding which have the potential to impact soil sustainability and forest productivity. The present study evaluated the effect of timber skidding by a rubber-tired skidder and farm tractor on the soil physical properties. The study site was located in Hafdaghanan plantation region in the north of Iran. Two treatments that consisted of skidding by HSM 904 skidder and ITM285 farm tractor equipped with trailer were applied. The trails were included in three traffic levels: primary, secondary and tertiary. Treatment effects were tested using analysis of variance (ANOVA) with skidding machine types and traffic levels. Results indicated that machine type and traffic intensity are the effective factors on soil physical properties. The results showed that with an increase of traffic frequency, bulk density increased but total porosity and soil water content decreased. The results of the study provide clear evidence that farm tractor is a more environmentally friendly machine than rubber-tired skidder in the plantation area.

“…In this case there is a need of optimization of interactions between soil, plant and machine, and focusing on such solutions which would allow to obtain high yields which satisfy the economic conditions of nursery production . The issue of the influence of soil density on the forest environment is still tested due to the complexity of the problem and the numerous factors and interactions related to forest production, including ecological and economic aspects (Ampoorter et al, 2007;Blouin et al, 2008;Picchio et al, 2012;Tan et al, 2006). Also, research is conducted in the range of the influence of soil density on forest trees species seedlings cultivated in forest nurseries (Blouin et al, 2008;Cubera et al, 2009;Onweremadu et al, 2008;Zhao et al, 2010).…”

The paper presents the results of an analysis of the influence of soil bulk density in a forest nursery plot on the growth and quality parameters of Scots pine and European beech seedlings. Particular density variants were obtained using a tractor device exerting controlled pressure on the soil, while field examinations were performed on an area of ‘Kłaj’ forest nursery in Niepołomice Forest District. Three series of plots were prepared for each species, applying a unit pressure of the values of 50, 100, 150, 200, 250 kPa, corresponding to the dry bulk density in the range of 1.03-1.19 g cm-3, and control plots without the pressure. Seeds of the examined species were sown on the prepared plots, and after 6 months of growth the seedlings were subjected to biometric analysis determining differentiation in root neck diameter, length of the above-ground part and root system, as well as dry mass of particular parts of the plant. The quality of the seedlings was also determined using the method of Schmidt-Vogt. The results obtained show that the change in dry bulk density soil significantly affected most of the growth parameters of the examined seedlings. Especially high negative correlations were obtained for the length and dry mass of the root system. A significant influence of dry bulk density variant on all growth parameters of Scots pine seedlings, and on some parameters of European beech was demonstrated. An increase in soil bulk density clearly caused also a deterioration of European beech seedlings quality

A literature review on harvester and forwarder equipment was conducted using the open access international scientific databases. The aims of this study were to evaluate the main interests of different research topics elaborated in 28 countries around the world in the last 23 years. The time span of the main articles ranged from the beginning of the year 1990 to end of 2012. The evolution trend of research topics was analyzed for this time period in order to relate them to possible future research directions in Romania. Most of the used literature was extracted mainly from scientific journals and conference proceedings, summing up a total of 105 references that were further analyzed. As expected, the synthesis of the references, pointed out that most of the interests and attention of the scientists has been given to productivity, costs and time expenditure on one hand, followed by studies on soil impact, environment and tree damage on the other hand. Topics referring to fuel-lubricants consumption and computer simulations didn't had the same impact among the researched literature, accounting for the smallest number of the cited articles. The obtained results will fill in the gap in future research by using scientific approaches particular to the Romanian conditions.
