This makes clarification of various factors affecting its secretion at tapping quite relevant. Drained pine stands on transitional peat soils in the Vologda Region were taken as an example to study how the following factors influence turpentine output at tapping: absolute peat humidity, air temperature at different peat soil depth and in the area of incisions, as well as ground-water level throughout the inter-channel space of the drained forest belt. It was empirically found that mature drained pine forests in the southwest of the Vologda Region have high resin productivity. It has been proved that resin productivity is strongly influenced by the level of soil and ground water, soil temperature at the depth of 5 and 10 cm and current air temperature at the level of resin blaze location. Dependence of pine turpentine output from one cut at tapping is well presented in the graphical equation y=9.407e0.49x. Fluctuations of pine turpentine output variability from one cut on the inter-channel space remain at a low level (9–10 %). Soil humidity proved to have no significant effect on resin output at tapping; however, at the depth of 20 (30) cm from the surface, it produced a negative effect on resin productivity.Authors
