The economic advantage of analyzed Brownfield investments is that there are already certain capacities and infrastructure in a specific location. The research found that the funds invested in the cleaning of the terrain, waste treatment with the so-called. "Wild" landfills, in adaptation of buildings, arrangement of green areas, improvement of infrastructure and the like, have economic and financial justification. In addition, a number of other qualitative effects of general interest have been highlighted. The effects of this investment are considered from socioeconomic, environmental and other aspects, as well as to the development of local economy and environmental protection. In addition to the ecological and economic aspects of investing in Brownfield investment, special attention should be paid to risk management and social aspects of local sustainable development.

The objective of this study is to assess the long-term cumulative effects of change in land-use type on some soil properties in the continental lowland ecosystems of Western Serbia. Three adjacent land-use types (deciduous forest, natural grassland and arable soils that have been converted from forests for more than 100 years) were chosen for the study. Disturbed and undisturbed soil samples were collected from nine sites at each of the three different land-use types from the depths of 0-10, 10-20 and 20-30 cm in noncarbonated Fluvisol. Conversion of forest to grassland and arable soil has led to significant decrease in total porosity (TP), infiltration rate (IR) and soil organic matter (SOM). The bulk density (BD) was lower in forest compared to the adjacent grassland and arable (ex-forest) soils. In addition, microaggregate stability, determined by the clay dispersion ratio (CDR) and aggregated silt and clay (ASC) indices, was significantly higher in forest than in grassland and arable soil. In conclusion, the results of this study indicate that removal of permanent vegetation in the conversion process from forest and grassland areas to cultivated land may lead to loss of soil productivity and serious soil degradation. Obviously, there is a need for greater attention to developing sustainable land use practices in management of these ecosystems to prevent further degradation of soils in the region.

Field experiments were conducted in Vojvodina, Serbia, to expand and improve knowledge about the effects of different levels of irrigation on maize grain yield and quality. The studied irrigation treatments were: full irrigation (I 100), 75% (I 75) and 50% (I 50) of I 100 , and no irrigation (I 0)-rainfed. The irrigation level affects maize grain yield; protein, starch, and oil content; and mineral composition. The results show that that yield decreases with increasing water deficit in three study years. On average, full irrigation results in the highest oil content and rainfed conditions in the lowest. The starch content increases and the oil content decreases with decreasing irrigation. Irrigation significantly increases the concentrations of K, Mg, Fe, Mn, and Zn, and reduces the Ca concentration compared to the rainfed treatment. A 25% water deficit (I 75) has a positive effect on certain maize grain nutrients and the yield is significantly reduced. The highest grain yield and oil content are achievable with full irrigation. For good nutrientional quality of maize, treatment I 75 can be proposed under similar soil and climate conditions.

This comparative study presents the composition and stability of structural aggregates in humus horizons (0-30 cm) of noncarbonate silty-clay Fluvisols in the Kolubara River Valley, W Serbia. Aggregates collected from under a native forest were compared to aggregates from meadows and arable fields which underwent crop rotation for > 100 y. The results show that size distribution and stability of structural aggregates in the humus horizons of arable soil are significantly impaired due to long-term anthropogenization. In the humus horizons, the content of the agronomically most valuable aggregates (0.25-10 mm) decreased by a factor of ≈ 2, from 68%-74% to 37%-39%, while the percentage of cloddy aggregates (>10 mm) increased by a factor of ≈ 2, from 23%-31% to 48%-62%, compared to forest aggregates. The long-term-arable soil had significantly (p < 0.05) lower aggregate stability, determined by wet sieving, than meadow and forest soils. The lowest aggregate stability was found in aggregates > 3 mm. Their content is ≈ 2.5-3 times lower in arable soil (13%-16%) than in forest soil (32%-42%) at a depth of 0-20 cm. The largest mean weight diameters of dry aggregates (dMWD) with a range between 12.6 and 14.7 mm were found in arable soil, vs. 9.5-9.9 mm in meadow and 6.5-8.3 mm in forest. The arable soil had significantly lower mean weight diameters of wet-stable aggregates (wMWD) and a lower structure coefficient (Ks) than forest and meadow soils. The dispersion ratio (DR) of arable soil was significantly higher than that of forest and meadow soils. Forest and meadow showed a significantly higher soil organic-matter content (SOM) by 74% and 39%, respectively, compared with arable soil, while meadow uses decreased the SOM content by 57% compared with forest at a depth of 0-10 cm. In conclusion, the results showed that long-term conventional tillage of soils from natural forest and meadow in the lowland ecosystems of W Serbia degraded soil aggregate-size distribution and stability and reduced SOM content, probably resulting in lower productivity and reduced crop yields.

The study aim of the experiment was to determine the effect of different irrigation regimens on water-yield relationships of potato. The study was carried out at the experimental field of the Institute of Field and Vegetable Crops in Novi Sad in the period 2002-2003. The trial included three irrigation variants (pre-irrigation soil moisture of 60, 70 and 80% of field water capacity - FWC, or irrigation was performed when 70%, 50% and 30% of available soil water, respectively, was consumed), and the non-irrigated, control variant. The trial was established in a system of random blocks and adapted to technical specifications of the sprinkling irrigation. Water used on evapotranspiration of potato was determined by balancing the amounts of water taken up from the soil layer of 2 m depth, from natural rainfall and irrigation. To assess the effectiveness of irrigation IWUE and ETWUE coefficient...

The field experiment was carried out in 2018 on the Experimental field of the Institute of field and vegetable crops in the Department of alternative crops in Bački Petrovac. Maize hybrid NS 6030 was used for the trials. The plants were irrigated by a drip system with a lateral in each row with drippers spaced every 0.33 m. The drippers had an average flow rate of 2.0 l h-1 under the pressure of 70 kPa. The differences in yield of maize in the irrigation conditions were not statistically significant compared to the variant without irrigation because the year was favorable for maize production. As well there was no difference among variants used for the calculation of maize evapotranspiration. Maize evapotranspiration in the growing season (ETm) were 502 mm and 429 mm by using ETo a...

A 3-year field study was conducted to investigate the effects of different irrigation regimes on yield parameters and water productivity of sprinkler-irrigated soybean [Glycine max (L.) Merr.], grown under wet, semi-dry and dry conditions in a temperate environment. Four irrigation levels were applied: full irrigation (I 100), 65% and 40% of full irrigation (I 65 and I 40) and non-irrigated control (I 0). On average, the I 0 treatment resulted in the highest harvest index (HI) and I 100 produced the lowest HI. A significant quadratic correlation between seed yield and crop water use was observed in dry and semi-dry year. The irrigation regime significantly influenced seed yield and water use. I 65 treatment produced the highest seed yield (3.69 t ha-1) and showed the highest water productivity (WP) (0.90 kg m-3) and irrigation WP (1.08 kg m-3). The present study indicated that irrigation is necessary for soybean cultivation in semi-dry and dry years i.e., when seasonal precipitation is lower than about 300 mm. In wet years, with a favourable amount and distribution of precipitation during the growing season, yields are similar to those achieved with irrigation and high ET values of soybean are attributable to increased evaporation.

The Vukan Mountain is formed of Jurassic limestones and dolomites, whereas the foot and toe slopes are of fluviatile-colluvial origin. A total of 42 soil profiles were examined. Soil profile locations were determined with respect to elevation differences, accounting for a set of six profiles for every 5-m elevation increase between 175 and 210 m a.s.l. The area is characterized by the dominance of chernic and mollic topsoil horizons and the major part of the area is covered with Phaeozems. Five Reference Soil Groups were found in a very small area. Eleven soil profiles are Chernic Phaeozems, five are Cambic Phaeozems, and twelve are Rendzic Phaeozems. The central part of the study area is characterized by the accumulation of secondary carbonates and Chernozems were identified. The northern part of the study area is covered with Fluvisols, Calcisols, and Leptic Rendzic Phaeozems, whereas Chernic and Cambic Phaeozems and Eutric Cambisols cover the western part of the study area. The differences in the CaCO 3 content in the gravels, the differences in the gravel content, and the different lateral and vertical distribution of CaCO 3 are strong evidence of surface processes that occurred in the past. The presence of different geological layers and buried horizons suggests fluviatile processes. The spatial distribution of soils is related mainly to parent material occurrence, and colluvial and alluvial processes that occurred in the past. The soil map created in GIS has Reference Soil Group as central unit following Rule 1 for map legend creation, except in the case of Phaeozems, which are present as Phaeozems (Leptic) and Phaeozems (other) following Rule 5. This soil survey with approximately one soil profile per 4 ha has indicated considerable soil heterogeneity in the study area. Detailed surveys are therefore recommended for areas with pronounced heterogeneity of soil-forming factors.

Soil properties were determined following standard procedures, and total contents of PHEs were analyzed by atomic absorption spectrometer. Concentrations of Cd, Co, Fe, Mn, Pb and Zn were the highest in soil profiles sampled 1 km away from the CFPP, concentrations of Ni and Cu gradually increased up to 4 km, and the highest Cr concentrations were measured in samples taken 6 km away from the CFPP. The highest concentration of PHEs analyzed, except Mn, corresponded with predominant wind directions. Depth did not show significant impact on distribution of any PHEs investigated. Among soil properties, the total organic carbon showed the closest relationship with the PHEs. Data were processed by a principal component analysis which enabled distinguishing anthropogenic from natural influences on soil properties and PHE contents. Although the impact of CFPP operations is obvious, assets of principal component analysis did not allow clear distinction of CFPP's contribution from parent material in enrichment of PHE contents in the soil in the study area.

A fundamental task of soil monitoring systems is to serve as a tool for land management in sense of sustainable development. In spite of the fact, that this task is common to all countries nowadays, there are still differences in metodologies and indicators of soil quality. Diversity of soil types may hinder identification of soil quality factors and indicators at a national scale. Assessment of soil quality is the basis for assessing sustainable soil management in this century. The objective of this paper was to identifay some soil physical, chemical and biological indicators for soil quality monitoring in sustainable agricultural management at national level. In many ways, soil quality is one measure of ecosystem health. Conserving soil quqlity means protecting the full range of ecological services high-quality soils provide.

As such, soybean yields vary from year to year and are generally low in dry years. Soybean irrigation leads to yield increase and less variation among years in arid, semi-arid, humid and sub-humid regions (Al-Tawaha et al. 2007, Sincik et al. 2008). Irrigation also affects the chemical composition of soybean (Kumawat et al. 2000, Bennett et al. 2004) including protein, oil, sugar and minerals (Bellaloui et al. 2015). Soybean quality depends on the oil and protein content, as it is the main source of high-quality protein and oil (Grieshop and Fahey 2001). More food of greater nutritional value, such as soy milk and tofu, is produced from soybeans with higher protein content (de Moraes et al. 2006). Users of these products prefer less oil and more protein (Kumar et al. 2006). Soybean is an important source of macro-and microminerals, such as P, K, Ca, Mn, Zn, Fe and B, which are indispensable in human food. A lack of these elements can lead to human malnutrition and health issues (Bouis 2003, Lu et al. 2008). As such, soybean quality improvement is extremely important for enhancing human and livestock nutrition (Bellaloui et al. 2010). According to available literature on the subject, the mineral
