Step-by-step explanation:
Agriculture in Eastern Europe is threatened by deteriorating soil quality, according to a study by a European Union (EU) research center. More than 16% of land in the EU is affected by soil degradation. In the eastern European countries that entered the EU, more than one third of the land is affected.
Expensive measures to improve soil fertility add pressure to the so-called Common Agricultural Policy (CAP), the EU's agricultural subsidy system, according to the European Soil Atlas document. According to this study, urbanization, climate change, pollution and unsatisfactory agricultural practices all contribute to the decline in soil quality.
