ABSTRACT
The report shows the results of investigations and analyses on four experimental areas located at the “Kazimierz” quarry (in Pojezierze Kujawskie latitude 52o20’ N, longitude 18o05’ E). The results of the investigations show the dynamics of moisture in the upper layer of post mining grounds are formed under metrological conditions. It shows that the most important dynamic of water retention occurred on the upper cultivated layer of post mining grounds in which there was a moisture reaction to the water precipitation. An unprofitable distribution of precipitation during the vegetation period 2013 caused this water deficit to the plants cultivated on post mining grounds. The longest water deficit (63 days) occurred in profiles typical to crop cultivation (average 12 mm). The results of the investigation confirm that post mining grounds should cultivate plants which are resistant to water deficit and which would benefit from the water reserves in the deeper layers of post mining grounds and which have deep roots system, such as lucerne.
