In mechanized timber harvesting, it is common practice to build brush mats from logging residues on skid trails. Protective effects of brush mats against soil compaction are documented by several studies. On the other hand, a large quantity of nutrients is concentrated on the skid trail. Fully mechanized harvesting has been criticized frequently for this reallocation of nutrients. Is there real...

Upscaling an operation typically results in economies of scale, i.e., cost advantages business, especially when the production unit’s utilization rate can be improved.
