AB  - Tillage methods and intensity can be used as means of improving macronutrient and trace element concentration in soil and crops. A two-year field experiment was conducted to examine the impact of two cropping systems-intensive (ICS) and conservation (CCS), on the macro- and microelements in the soil and their accumulation in the grain of two cultivars of winter wheat. The experiment was conducted in a randomized complete block design with three replications of each tillage treatment. The results showed that the content of available N (0.7 kg ha(-1)) and organic matter (0.04%) slightly increased in CCS compared to ICS. The concentrations of Ca, K, and S macroelements and microelements such as Ba, Cr, Hg, and Sr in the soil were significantly higher in CCS than in ICS. Higher concentrations of macroelements K and P, microelements such as Fe, Zn, and As, and the greater value of the bioaccumulation factor for elements essential to humans such as P, Cu, Fe, and Zn, were also found in CCS compared to ICS. On the other hand, wheat cultivars grown in ICS were more efficient at accumulating macroelements and some trace elements than ones grown in CCS. While it is not without challenges, the conservation cropping system could represent an important part of the long-term strategy to sustainably improve soil fertility and the nutritional quality of the wheat grain.

AB  - Cocoa beans are part of the cocoa plant fruit (Theobroma cacao L.) used to prepare various products such as chocolate, cocoa butter, jelly, liqueurs, cosmetics, etc. Dark chocolate is consumed worldwide by different populations and is known for its good taste, making it one of the most favoured food products. This work aimed to determine the content of total polyphenols (TPC), total flavonoids (TFC), and the antioxidant potential measured through the ability to scavenge DPPH free radicals (DPPH), ferric reducing power (FRAP), and total antioxidant capacity (TAC), as well as major and trace elements contained in twelve commercially available dark chocolate samples, with cocoa content ranging from 40% to 99%. The total polyphenols content ranged between 10.55 and 39.82 mg/g GAE, while the total flavonoid content was from 10.04 to 37.85 mg/g CE. All applied antioxidant assays indicate that the sample with the highest cocoa percentage shows the greatest antioxidant activity (DPPH: 48.34% of inhibition; FRAP: 89.00 mg/g GAE; TAC: 83.86 mg/g AAE). Statistical methods were applied to establish the differences between the samples concerning TPC, TFC, DPPH, FRAP and TAC, as well as to differentiate the samples according to the mineral content. The results indicated that the differences in TPC and TFC between different samples depended on the cocoa content and the addition of dried fruit pieces. A good correlation between antioxidant potency composite index (ACI) and declared cocoa content was noticed (R-2 = 0.8034), indicating that the declared percentage of cocoa is a reliable indicator for antioxidant activity of analysed dark chocolate samples. The nutritional evaluation proved that the studied chocolate samples were an excellent source of Mg, Fe, Mn and Cu.
