The objective of this work was to determine the quality and use of agricultural land within the Brdnikova dry reservoir and how this green-gray infrastructure affects agricultural production in the detention area. Using topographic maps and the Franciscan cadaster, we examined land use in the area of the Brdnikova dry detention basin and the Glinščica watershed as it changed since the mid-19th century. In the second part, we visited the area of the dry reservoir and took disturbed and undisturbed soil samples at three selected sites. We determined the porosity and density of the soil, the amount of water at the field capacity (pF 1 and 2.54) and at the wilting point (pF 4.2). In the third part, we conducted a survey among land users of the Brdnikova dry reservoir using a questionnaire. Evaluation of the maps showed that the area has been heavily urbanized over time, with urban work increasing in the 21st century. The areas along the Pržanc and Glinščica streams were preserved. The current appearance of the area was influenced mainly by land reclamation works, when a dry reservoir was built in the 1980s for flood control. Soil density ranged from 0.94 to 1.19 g/cm3, field capacity from 43 to 55.8 %, and wilting point from 17.7 to 22.3 %. A survey of land users showed that they had negative experiences with the expansion of the capacity of the Brdnik dry reservoir, that the conditions for agricultural production were deteriorating, and that agricultural land in the area is increasingly being used for the construction of habitats.
