AB  - This study was conducted to compare soil particle density (ρs), soil total porosity (TP), liquid limit (LL), plastic limit (PL), and plasticity index, and their relations with soil organic matter (SOM), of non-carbonate silty clay Fluvisols under different land uses. Three neighboring land uses were studied: native deciduous forest, arable land, and meadow, managed in the same way for more than 100 years. Soil was collected from 27 soil profiles and from three depths (0–15, 15–30 and 30–45 cm). Land use caused statistically significant but different impacts on soil properties, particularly in the topsoil. The forest topsoil measured the lowest ρs and bulk density (ρb) but the highest SOM and soil water content at PL, compared to meadow and arable soil. Statistically significant linear relationship was observed with the SOM content and ρs (− 0.851**), ρb (− 0.567**), calculated TP (0.567**) and measured TP (− 0.280**). There was a nonlinear relationship between SOM and LL (0.704**) and PL (0.845**) at the topsoil. The findings suggested that SOM content strongly affected ρs, ρb, TP, LL and LP. This regional study showed that the conversion of forestland into agricultural land without appropriate measures to conserve SOM leads to the degradation of physical and rheological soil properties.

AB  - Human activity can significantly alter land cover characteristics and subsequently hydrological and other processes in river basin. The aim of this study was to determine infiltration of surface (0-30 cm) sandy loamy Fluvisol under natural meadow vegetation and adjacent Fluvisol which is used more than 10 years as the arable soil, with similar conditions of pedogenesis in the Nišava River Valley, in the vicinity of Pirot (Serbia). The other conditions of pedogenes were similar. Measurement of infiltration was performed by double cylindrical infiltrometer. Three infiltration runs were carried out for each location. The results showed that the in the arable soil compared with meadow, constant (steady state) infiltration rate and cumulative infiltration were about 699% and 447% higher, respectively. The change in soil structure caused by loosening of the plowing layer because of tillage is the main factor causing the increase in infiltration of water into the soil after conversion of natural grassland to arable soil. These results can be used in predicting surface runoff, saturated hydraulic conductivity of the surface layers and groundwater recharge, and also in the development or selection of the most efficient methods of irrigation sandy loam soils.

AB  - This study examines the effects of different irrigation regimes on seed yield and yield components of sprinkler-irrigated soya bean [(Glycine max (L.) Merr.] under field conditions in 2006, 2007 and 2008 in Zemun Polje (Srem, Srbija). Four irrigation regimes: 80-85% (T1), 70-75% (T2), 60-65% (T3) of field capacity, and non-irrigated regime (T0) were evaluated each experimental year. The experimental design was a randomised complete block with four replications on a Calcaric Chernozem. Water stress (drought) during growing season in the non-irrigated treatment (T0) decreased plant physiological activity, vegetative growth, and productivity of soya bean. Irrigation treatments significantly (P  lt  0.01) influenced soya bean seed yield and yield components. The treatment T2 produced higher seed yield than T1 and T3. Irrigation regimes had statistically significant different effects on yield components such as the plant height at harvest, number of pods per plant, number of seeds per plant, mass of pod with seeds per plant, 1,000 seed mass and hectoliter mass of soya bean seeds. Yield reduction was mainly due to a lower number of pods and seeds per plant and lower seed mass. The T1 treatment had the highest plant height of soya bean in all three growing years. The results have shown that under water scarcity, the treatment T3 is an acceptable irrigation strategy to stabilize and increase soya bean yield in Srem and neighboring countries in the region, provided that this practice is not prevented by economic constraints.
AB  - U ovom radu ispituje se uticaj različitih režima navodnjavanja orošavanjem na prinos i komponente prinosa semena soje [(Glycine max (L.) Merr.] u poljskim uslovima u 2006, 2007. i 2008. godini u Zemun Polju (Srem, Srbija). Svake godine istraživana su po tri režima navodnjavanja, i to sa 80-85% (T1), 70-75% (T2), 60-65% (T3) poljskog vodnog kapaciteta i prirodni vodni režim bez navodnjavnja (T0). Ogled je izveden po metodi slučajnog blok sistema u četiri ponavljanja na karbonatnom černozemu. Deficit vode u toku vegetacionog perioda u nenavodnjavanom tretmanu (T0) smanjio je fiziološku aktivnost biljaka, vegetativni rast i produktivnost soje. Navodnjavani tretmani su vrlo značajno (P  lt  0,01) uticali na prinos zrna soje i komponente prinosa. Na tretmanu T2 postignut je veći prinos semena nego na tretmanima T1 i T3. Iako je tretman T2 dobio oko 37% manje vode za navodnjavanje u poređenju sa T1, prinos soje povećan je u proseku za 11%. Navodnjavani režimi imali su statistički značajno različite uticaje na komponente prinosa kao što su visina biljaka u vreme žetve, broj mahuna i zrna po biljci, masa mahuna po biljci, masa zrna po biljci, masa 1.000 zrna i zapreminska masa zrna. Smanjenje prinosa je uglavnom posledica manjeg broja mahuna i zrna po biljci i manje mase 1.000 zrna. Tretman T1 imao je najveću visinu biljaka u sve tri godine ispitivanja. Rezultati su pokazali da je tretman T3 prihvatljiva strategija navodnjavanja za stabilizaciju i povećanje prinosa soje u Sremu i susednim zemljama regiona u uslovima ograničenih vodnih resursa, pod uslovom da ova praksa nije sprečena ekonomskim ograničenjima.

AB  - Changes in land use can significantly affect aggregate distribution and water stability of structural aggregates. This study was conducted in the Kolubara River Valley, Western Serbia, to determine the effects of land use changes on composition and water stability of aggregates in humus horizons (0-30 cm) of noncarbonated Gleyic Fluvisols. This study was conducted at nine sites, where each site contained two adjacent land uses of natural grassland and arable land which underwent crop rotation for >100 years. Soil samples were taken from depths of 0-10, 10-20 and 20-30 cm for each land use. When the grassland was converted into arable land, the content of the agronomically most valuable aggregates (0.25-10 mm) of cultivated soils for a depth of 0-30 cm was significantly reduced by 22-40%, while the percentage of cloddy aggregates (>10 mm) increased by 41-68%, compared to grassland. In addition, the long-term arable soil had significantly (p lt 0.05) lower aggregate stability, determined by wet sieving, than grassland. The lowest aggregate stability was found in aggregates > 3 mm. Their content is ≈ 2.3 times lower in arable soil (12.6%) than in grassland (28.6%) at a depth of 0-10 cm. In addition, meanweight diameters of dry and wetstable aggregates and structure coefficient showed significant differences between land use at a depth of 0-30 cm. The results showed that the conversion of natural grassland to arable land in the lowland ecosystems of Western Serbia degraded aggregate distribution and stability.
AB  - Istraživanja su sprovedena u dolini reke Kolubare da bi se utvrdili efekti promene načina korišćenja zemljišta na agregatni sastav i vodootpornost strukturnih agregata u humusnom horizontu (0-30 cm) beskarbonatne livadske crnice. Izabrano je devet lokacija koje su na bliskom rastojanju imale površine pod prirodnom livadskom vegetacijom i oranice koje su stvorene pre više od 100 godina razoravanjem prirodnih livada. Nakon razoravanja prirodnih livada i njihovog pretvaranja u oranice, sadržaj agronomski najpovoljnijih strukturnih agregata (prečnika 0,25-10 mm) u oranicama na dubini 0-30 cm, značajno je smanjen, za 22-40%, dok je sadržaj grudvastih agregata (>10 mm) povećan za 41-68 %, u poređenju sa livadom. Pored toga, višegodišnje oranice imaju značajno (p lt 0,05) manju vodootpornost strukturnih agregata, određenih mokrim prosejavanjem, od livada. Najmanju vodootpornost pokazali su strukturni agregati prečnika >3 mm. Takođe, prosečni maseni prečnici suvih i vodootpornih agregata i koeficijent strukture pokazali su značajne razlike između različitih načina korišćenja zemljišta na dubini 0-30 cm. Razoravanje livadskih crnica pod prirodnom livadskom vegetacijom istraženog područja i njihova višegodišnja obrada doveli su do značajnih negativnih promena agregatnog sastava i smanjenja vodootpornosti strukturnih agregata.

When the grassland was converted into arable land, the content of the agronomically most valuable aggregates (0.25-10 mm) of cultivated soils for a depth of 0-30 cm was significantly reduced by 22-40%, while the percentage of cloddy aggregates (>10 mm) increased by 41-68%, compared to grassland. In addition, the long-term arable soil had significantly (p lt 0.05) lower aggregate stability, determined by wet sieving, than grassland. The lowest aggregate stability was found in aggregates > 3 mm. Their content is ≈ 2.3 times lower in arable soil (12.6%) than in grassland (28.6%) at a depth of 0-10 cm. In addition, meanweight diameters of dry and wetstable aggregates and structure coefficient showed significant differences between land use at a depth of 0-30 cm. The results showed that the conversion of natural grassland to arable land in the lowland ecosystems of Western Serbia degraded aggregate distribution and stability., Istraživanja su sprovedena u dolini reke Kolubare da bi se utvrdili efekti promene načina korišćenja zemljišta na agregatni sastav i vodootpornost strukturnih agregata u humusnom horizontu (0-30 cm) beskarbonatne livadske crnice. Izabrano je devet lokacija koje su na bliskom rastojanju imale površine pod prirodnom livadskom vegetacijom i oranice koje su stvorene pre više od 100 godina razoravanjem prirodnih livada. Nakon razoravanja prirodnih livada i njihovog pretvaranja u oranice, sadržaj agronomski najpovoljnijih strukturnih agregata (prečnika 0,25-10 mm) u oranicama na dubini 0-30 cm, značajno je smanjen, za 22-40%, dok je sadržaj grudvastih agregata (>10 mm) povećan za 41-68 %, u poređenju sa livadom. Pored toga, višegodišnje oranice imaju značajno (p lt 0,05) manju vodootpornost strukturnih agregata, određenih mokrim prosejavanjem, od livada. Najmanju vodootpornost pokazali su strukturni agregati prečnika >3 mm. Takođe, prosečni maseni prečnici suvih i vodootpornih agregata i koeficijent strukture pokazali su značajne razlike između različitih načina korišćenja zemljišta na dubini 0-30 cm. Razoravanje livadskih crnica pod prirodnom livadskom vegetacijom istraženog područja i njihova višegodišnja obrada doveli su do značajnih negativnih promena agregatnog sastava i smanjenja vodootpornosti strukturnih agregata.",
