- Abstract
The aim of research was to assess the changes of annual radial increment of Scots pine forests in the vicinity of intensive and moderate industrial pollution of 'Achema' factory producing mineral fertilizers. Our results indicate that the radial growth of the pine tree can be divided into three different periods: growth promotion, growth inhibition and growth recovery. Low levels of nitrogen emissions were beneficial for tree growth: the radial increment in the intensive and moderate pollution zones increased by 15-25% and 10%, respectively compared to control. During the growth inhibition period, the total annual industrial emission was 37-40 kt, and 40-45% radial growth loss was observed for the closest and 15-20% for the most distant stands. The radial growth decrease slowed down and the recovery of damaged stands began in 1990-1992 then air pollution was considerably reduced. The rate of forest recovery was high for the most damaged stands: their radial growth was close to control in 2000-2011.
