“…In 1982, the time required to plant 10 ha of upper coastal plain soil was 11 h for a machine-planting crew or 15 h for a hand-planter [64]. In contrast, some container-only machines plant less than 400 seedlings per hour [72,73]. The time required to machine plant 1000 pine seedlings depends on the spacing between seedling rows.…”

Artificial regeneration is successful when high-performing seedlings are transported with care to the planting site, stored for a short period in an environment without desiccation or fungal growth, and planted in a deep hole, so roots are in contact with moist soil. One of the requirements for success is the ability to avoid common planting mistakes. Due, in part, to the use of container stock plus an increase in rainfall, the average first-year survival of pine seedlings (89%) in the southern United States is about 15% greater now than 45 years ago. However, when survival is less than 50% six months after planting, some landowners seek reimbursement for their loss. Some assume poor seedling quality was the cause without realizing that anaerobic soils or sudden freeze events, shallow planting holes, pruning roots, a lack of rain or underground insects can kill pines. With a focus on pines planted in the southern United States, we list non-nursery factors that have killed seedlings in North America, Africa and Europe.

Currently, in the Russian Federation, a large number of areas require reforestation. Introduction of new technologies in artificial reforestation (planting seedlings with a closed root system) requires the use of new means of mechanization when planting seedlings. The assessment of the degree of similarity and difference of the selected structures was carried out on the basis of statistical analysis (hierarchical classification). The country's industry practically does not produce tree planting machines for planting seedlings with a closed root system. Imported specimens of forest planting machines are expensive, require aggregation with heavy equipment, which is practically absent in forestry. In addition, climatic conditions may also be a limitation in the use of imported equipment. In connection with the above, Voronezh State University of Forestry and Technologies has developed designs of universal planting machines with rotary and chain planting mechanisms. They enable planting of both standard seedling and seedlings with closed root system. The use of universal tree planting machines in forestry enables to keep one tree planting machine instead of two specialized ones. This will significantly save on maintenance and storage of mechanisms
