Soil aggregate stability is an ideal integrative soil quality indicator, but little is known about the relevance of such an indicator with soil depth for salt-affected soils. The objective of this study was to determine soil aggregate stability and identify preponderant aggregation factors, both in topsoil and subsoil horizons in salt-affected conditions. We conducted field investigations by describing soil profiles in pedological pits and by collecting soil samples from different field units. Soils were sampled within different soil horizon types, from superficial tilled organo-mineral horizons to mineral horizons. For all soil samples, we determined the mean weight diameter (MWD) as an indicator of soil aggregate stability and also determined associated physical and chemical properties in some samples. The measured MWD value from 0.28 mm to 1.10 mm could be categorised as unstable, with MWD values and variability decreasing drastically from the topsoil to the deepest mineral horizons. Analysis of MWD in relation to physical and chemical properties suggested that the variability in the MWD value of A-horizons was influenced by both clay fraction abundance and soil organic carbon (SOC) content and the nature of the agricultural practices, while at deeper B-horizons, the decrease in SOC content and the variability in other soil properties with soil depth could be used to explain the overall low aggregate stability. In this study, investigations of soil pits coupled with measurements of soil aggregate stability indicated that it could be possible to restore soil structure quality by limiting deep soil profile compaction in order to improve salt leaching and exportation.

This influence of various rootstocks on the yield and grape composition of Sauvignon Blanc was examined. The yield on rootstock 41B/72 was 1 kg/vine or more higher than on rootstocks SO4 cl. 31, Riparia cl. 1 and Kober 5BB. The vines grafted on the Börner rootstock gave the highest weight of 100 berries (241 g). The highest seed weight of 100 berries (6.9 g) was found on rootstock 196/17 Cl, while the lowest one was on the Riparia cl. 1 (5.6 g). There was a strong, positive correlation (r = 0.91) between the berry and seed weights of vines on rootstock 41B/72 (2003). The total acidity content and the relationship between tartaric and malic acids were affected more by the weather conditions than by the rootstock. Relatively strong correlations between the grape yield and total soluble solids (r = -0.89), and between grape yield and total acidity (r = 0.76) were found in the grape juice on rootstock 41B/72 (in 2002).

Abstract. The choice of rootstock is important not only for the power that it induces on the grafted variety of grapes, but also with respect to its effects on mineral nutrition, content of sugars, total acids and other technological traits. Two table vine varieties-Misket Rusenski and Super ran Bolgar were the objective of the study, grafted on two different SO4 rootstocks (which is widely used in practice and thus accepted control) and Rupestris du Lot (with common name Montikola). A total of 12 technological traits were reported for both varieties during the vegetation. Data obtained were statistically analyzed using Fisher (F) and Student (t) evaluation criteria. The results showed different levels of significance of the individual traits in both varieties using Rupestris du Lot rootstock compared to the control. Via Fisher's criterion it was found that 58 % of the traits showed significant differences in Montikola rootstock compared to the control, as the comparison was made based on variability of the traits, while when using the Student criterion for statistical evaluation, the percentage was only 33. The highest significance was reported in the influence of the rootstock on the traits: number of seeds in 100 berries and resistance of berry to pick up from the fruit stalk for cv. Misket Rusenski, determined via both criteria. Comparing the samples tested regarding variability, significant differences were reported of Rupestris du Lot rootstock for the traits: % of berries in grapes and % of mesocarp in berry mass for the same variety. Rupestris du Lot rootstock has significant influence on content of sugars, total acids and mass of 100 seeds in cv. Super ran Bolgar (by the criterion of Fisher) and traits: % of mesocarp of berry mass and % of skin of berry mass (found by the criterion of Student). These traits influence significantly on tasting qualities of grapes and technological qualities of wine. As a result of the analysis of both vines (Misket Rusenski and Super ran Bolgar) a high degree of variability of the values of some technological traits was determined, and it is recommended both criteria to be used for better statistical evaluation.
