V nalogi, ki je del širšega projekta Daljinsko in bližnje zaznavanje suše (DABLIS) iz programa Po kreativni poti do znanja, smo predstavili podatke meritev vsebnosti vode v tleh. Na izbranih njivah podjetja Panvita d.o.o. v Prekmurju smo opravili občasne točkovne meritve. Prav tako so potekale kontinuirane meritve na globini 20 cm. Vsebnost vode v lahkih tleh je bila nižja kot v težkih tleh. Prav tako so obstajale razlike med nenamakanimi in namakanimi tlemi. V lahkih nenamakanih tleh je bila povprečna vsebnost vode 17,1 vol. %, v lahkih namakanih pa 23,5 vol. %. Vsebnost vode v težkih nenamakanih tleh je bila 23,6 vol % ter v težkih namakanih 24,0 vol. %. Razpršenost podatkov je bila večja pri lahkih tleh (od 4,3 do 30,3 vol. % pri lahkih tleh in od 15,5 do 27,9 vol. % pri težkih tleh). Prav tako je bil koeficient variacije praviloma večji za vsebnost vode v lahkih tleh (od 1,6 do 35,1 % pri lahkih tleh in od 2,3 do 9,6 % pri težkih tleh). Ob primerjavi nenamakanih in namakanih tal je bil koeficient variacije večji pri namakanih tleh (od 1,6 do 28,4 % pri nenamakanih tleh in od 2,3 do 35,1 % pri namakanih tleh).

• Title: Variability of soil water content at selected locations in Prekmurje

Abstract

In our work, which is part of the wider project DABLIS in the program On the Creative Path to Knowledge, we presented the data of soil water content measurements. On selected fields of Panvita d.o.o. in Prekmurje we made occasional accurate measurements. We also performed continuous measurements at a depth of 20 cm. Water content in light soils was lower than in heavy soils. There are also differences between non-irrigated soils in irrigated soils. In light non-irrigated soils a water content was 17.1 vol. % and in light irrigated soil 23.5 vol. %. Water content in heavy non-irrigated soils was 23.6 vol. % and in heavy irrigated soil 24.0 vol. %. Dispersion of data was greater for light soils (4.3 to 30.3 vol. % for light and from 15.5 to 27.9 vol. % for heavy soils). In addition the coefficient of variation for water content was greater for light soils (1.6 to 35.1 % for light and 2.3 to 9.6 % for heavy soils). Taking comparison of non-irrigated soil and irrigated soil the coefficient of variation was greater for irrigated soil (from 1.6 to 28.4 % for non-irrigated and from 2.3 to 35.1 % for irrigated soil).
