“…They further observed that the proportions of elements were different between milling fractions attributing this to different pathways for the translocation and accumulation of individual micronutrients to the grain that are influenced by N. Also Ciampitti and Vyn (2013) reported higher Cu, Fe, and Mn concentrations with N fertilization for maize grain in pure stands. Contrary to that, no effect of N fertilization on concentrations of Fe and Zn in grain of winter wheat and spring barley was observed by Sedlář et al (2014) and on micronutrient concentrations in grain of maize by Lošák et al (2011). Ahmadi et al (1993) observed even lower concentrations of Cu, Zn, and Mn with N fertilization in oat grain, attributing this to a dilution because of a higher grain yield.…”

SummaryIntercropping is of increasing interest in temperate regions. This study assessed the influence of nitrogen (N) fertilization and sowing ratio on concentrations and uptake of micronutrients copper (Cu), iron (Fe), manganese (Mn), and zinc (Zn) in grain and residue of oat and pea in three substitutive intercrops on a fertile soil in eastern Austria. N increased grain concentrations of Cu and Zn in oat and pea but decreased the nutrient harvest indices especially for pea. Intercropping did not affect grain concentrations of oat but those of pea were increased in one year in intercrops with a lower pea share. Residue concentrations of Cu and Zn in oat were increased in intercrops with lower oat share. Pea residue concentrations of all four micronutrients were affected by intercropping. Slightly higher grain nutrient yields could be obtained for Mn and Zn in oat-dominated unfertilized intercrops, whereas the residue micronutrient yields were higher in all intercrops compared to pure stands because of generally higher nutrient concentrations in intercrops. Consequently, advantages of oat–pea intercrops for increasing micronutrient yield in grain were limited, but intercropping can be a strategy for increasing the micronutrient yield in residue that can be used for ruminant feeding.

Soil contamination in the agricultural areas developed on open aquifer systems can be environmental problem. The subject of this study is the Cambisol soil developed in the area of the Velika Gorica well field. The aim of this research was to determine possible agricultural influence on the unsaturated zone of the Zagreb aquifer area where Cambisol soil is developed. Concentrations of potentially toxic metals (Cu, Cd and Zn) and major cations and anions (Na + , K + , NH 4 + , Mg 2+ , Ca 2+ , Cl-, NO 3-, and SO 4 2-) were determined in soil horizons. Correlations between physical and chemical soil properties, analysed ions and potentially toxic metals were made. Samples that were closer to the surface showed increased element concentrations, indicating the increased impact of agricultural activities in the research area. All analysed potentially toxic metals showed highest concentrations in residual fraction, which indicates the possible influence of agricultural activities such as usage of fertilizers, manure, sludge as soil fertilizer and fungicides, or point sources of contamination, uncontrolled, active or untended waste dumps and aerodeposition. Statistical analysis showed strong correlations between the concentrations of the studied potentially toxic metals and some soil properties such as soil texture, pH and organic matter. In addition, correlation results between nitrates and some potentially toxic metals such as Cu and Zn indicate that these elements come from the same source of contamination, in this case probably agricultural activity. Even though the influence of agricultural activities is recognized, all results show that the impact is decreasing after approximately 0.8 m depth.

Foliar Zinc-Selenium and Nitrogen Fertilization Affects Content of Zn, Fe, Se, P, and Cd in Wheat Grain

The grain yield and concentrations of Fe, Zn, Se, Cd, and P in two winter wheat genotypes and in vitro bioaccessibility of Fe and Zn under the effect of different nitrogen fertilization and Zn-Se foliar application were evaluated. The total grain Fe, Zn, and Se concentrations, as well as Fe and Zn concentrations, after in vitro digestion were under the strongest effect of foliar Zn-Se application. On the other hand, Fe and Zn bioaccessibility (%) were under the most substantial effect of genotype. Regarding the need to increase concentrations of essential micronutrients in wheat grain, foliar Zn-Se application is a reliable and accepted agricultural practice, but to improve mineral bioaccessibility in human nutrition, foliar Zn-Se application should be combined with the most responsive genotypes. For this reason, further research on the genotype specificity of wheat regarding micronutrient bioaccessibility should be carried out.
