Kmetijska raba površin znotraj suhega zadrževalnika Brdnikova

Podlesnik, Aljaž (avtor), Zupanc, Vesna (mentor)

Namen diplomskega dela je bilo ugotoviti, kakšna je kakovost in raba kmetijskih zemljišč znotraj suhega zadrževalnika Brdnikova in kako ta zeleno siva infrastruktura vpliva na kmetijsko pridelavo. S pomočjo topografskih kart in Franciscejskega katastra smo pregledali rabo tal na območju zadrževalnika Brdnikova in vodoprispevnega območja Glinščice in kako se je spreminjala od sredine 19. stoletja naprej. V drugem delu smo obiskali območje suhega zadrževalnika in na treh izbranih lokacijah odvzeli porušene in neporušene vzorce tal. Določili smo poroznost in gostoto tal, količino vode pri poljski kapaciteti (pF 1 in 2,54) ter pri točki venenja (pF 4,2). V tretjem delu smo naredili pisno anketo med obdelovalci zemljišč na območju suhega zadrževalnika Brdnikova. Na podlagi kart smo ugotovili, da je območje s časom postalo zelo urbanizirano, z večjim razmahom urbanega dela v 21. stoletju. Ohranila so se zemljišča vzdolž potoka Pržanc in Glinščica. Na sedanji videz območja so najbolj vplivala melioracijska dela, ko je bil zgrajen suh zadrževalnik za protipoplavno zaščito v 80 letih prejšnjega stoletja. Gostota tal je bila med 0,94 in 1,19 g/cm3, poljska kapaciteta med 43 in 55,8 %, točka venenja med 17,7 in 22,3 %. Anketa med obdelovalci zemljišč je pokazala, da imajo z razširitvijo kapacitet zadrževalnika Brdnikova negativne izkušnje, pogoji za kmetovanje se slabšajo, kmetijska zemljišča na območju se namenja za vzpostavitev habitatov.

Izvleček

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.
