The aggregate output in Nowogród Bobrzański region has a long history. Initialy the aggregate was being mined from the bottom of the Bóbr river and from the directly adjacent terrains. The mining of the Dobroszów Wielki Deposit was begun in 1963. N2 - The mining lasted up to the seventies. After the end of the mineral mining, the formed excavations were reclaimed in agricultural direction. This reclamation direction was not the best choice. The reclamation works were performed improperly. The new created grounds had very unfavorable properties for cultivated plants. Improvement of these properties needs to incur high expenditures.
