Ugotavljali smo vpliv obdelave tal na hidravlične lastnosti tal. Raziskavo smo izvedli v vinogradu v Purissimi in v Baredih zaradi podobnih talnih in podnebnih razmer. Vzorce tal iz dveh globin (0-20 cm; 20-40 cm) smo v obeh vinogradih odvzeli na treh medvrstnih pasovih, kjer so bila tla trajno ozelenjena, in na treh, kjer so bila tla obdelana in neporaščena. Na porušenih vzorcih smo izmerili rastlinam dostopno vodo (poljska kapaciteta pri 0,33 bar in točka venenja pri 15 bar), stopnjo infiltracije z mini disk infiltrometrom ter gostoto tal in poroznost. Največje vodo zadrževalne lastnosti ima vrhnji sloj (0-20 cm) v trajno ozelenjenem delu medvrstnega prostora v obeh vinogradih. Gostota tal trajno ozelenjenega medvrstnega prostora vinogradov Purissima in Baredi je večja (1,42 oziroma 1,48 g/cm3) od gostote tal obdelanega medvrstnega prostora (1,34 oziroma 1,31 g/cm3). Stopnja infiltracije je bila na trajno ozelenjenih tleh večja od infiltracije na obdelanih tleh. Stopnja infiltracije je bila na trajno ozelenjenem medvrstnem prostoru vinograda Purissima med 33,73 in 50,43 cm/h, na obdelanih, golih tleh pa med 24,10 in 49,71 cm/h, medtem ko je bila v Baredih na trajno ozelenjenih tleh med 18,87 in 22, 62 cm/h, obdelanih pa med 14,37 in 21,31 cm/h. Infiltracija je v povprečju pri obeh načinih obdelave večja v vinogradu Purissima (39,74 cm/h) kot na Baredih (19,17 cm/h).

• Title: The impact of soil tillage of the interrow space in a vineyard on the hydraulic properties of the soil

Abstract

We studied the influence of soil tillage on the hydraulic properties of the soil. The study was carried out in the vineyards in Purissima and in Baredi, since they have similar soil and climatic conditions. We collected soil samples in both vineyards on three inter-row strips with permanent green cover (PGC) and on three strips with cultivated soil with scarce green cover (CS). On the disturbed soil samples, we measured plant-available water (field capacity at 0.33 bar and wilting point at 15 bar), infiltration rate with a mini-disk infiltrometer, and soil bulk density and porosity. The greatest water retention properties were measured in the top layer (0-20 cm) in the rows with PGC in Purissima and Baredi vineyards. The soil bulk density of the inter-row strips with PGC in both vineyards is higher (1.42 and 1.48 g/cm3, respectively) than the soil bulk density of the inter-row with CS (1.34 and 1.31 g/cm3, respectively). The infiltration rate was in general higher in inter-row strips with PGC than CS. On average, infiltration is higher in the Purissima (39.74 cm/h) than in the Baredi (19.17 cm/h). The infiltration rate ranged from 33.73 to 50.43 cm/h in the inter-row strips with PGC of the Purissima, and from 24.10 to 49.71 cm/h in the CS. The infiltration rate ranged from 18.87 to 22.62 cm/h in the inter-row strips with PGCof the Baredi vineyard and from 14.37 to 21.31 cm/h at the CS.
