“…The authors found that there were no significant differences in grain protein content between the three N rates studied, which they explained by the effect of variable weather conditions during cultivation in the individual years of the experiment. A greater effect of weather conditions on the content of major nutrients than the effect of the type and rate of fertilizers is also confirmed by the study of Mayer et al (2015).…”

“…Mayer et al (2015) found a significantly higher crude protein content (180 g kg -1 DM) in wheat fertilized with mineral fertilizers or mineral fertilizers in combination with organic fertilizers than in wheat fertilized with organic fertilizers, even at double rates, and in non-fertilized wheat (about 150 g kg -1 DM). In their research, wheat without fertilization was characterized by a significantly higher content of dry gluten (more than 120 g kg -1 DW) compared to the other fertilization treatments (about 100 g kg -1 DW).…”

Non-standard materials used for plant fertilization, require characterization to reduce any possible undesired effects. The aim of this study was to investigate the effect of fertilization with biogas digestate (BD) and mining waste (carboniferous mudstones (MS) from coal mine) on wheat yield quality and the bioaccumulation of heavy metals in wheat grains in relation to conventional fertilization (NPK) and no fertilization. Using the co-application of waste (MS+BD), the highest yield was obtained in the first and second year, but in the third year, a slight decrease in yield was observed compared to NPK. In all years, BD and MS+BD fertilization increased the content of protein, wet gluten, and phenols in wheat grain compared to NPK and no fertilization. Waste fertilization had a positive effect on the antioxidant capacity index of grain but only in the first year. The bioaccumulation index (BAI) demonstrated that NPK decreased BAI for Zn, B, Cd, and Mn, whereas MS+BD decreased BAI for Cu, Sr, Pb, Co, Ba, and Cr.

The processing quality of 37 wheat varieties grown in Hungary and Austria (2011-2013) were assessed under organic and conventional low input management. The varieties studied were developed using three breeding strategies (conventional, organic and their combination: BFOA). The aim was to evaluate the effect of the field management and to assess the performance of varieties developed using different breeding methods, based on their quality traits under different managements. Furthermore, properties were identified that could characterize wheat quality and be used effectively for selection under both types of growing conditions. Strong year and genotype effects were found for all the quality traits (protein, starch, gluten, GI, Zeleny, Farinograph water absorption, development time, stability and quality number, falling number, flour yield, hardness index) of the studied varieties, while the effect of the management was significant for the physical properties (test weight, thousand-kernel weight, hardness) and gluten quality characters (gluten spread, GI, dough stability) of the grain. The standard deviation of the gluten quality traits characterized the differences between the breeding 3 strategies. It proved possible to pre select organic varieties for quality traits with high broad-sense heritability under conventional growing conditions, but direct selection in organic fields is suggested for gluten quality characters.

Plant roots are major transmitters of atmospheric carbon into soil. The rhizosphere, the soil volume around living roots influenced by root activities, represents hotspots for organic carbon (OC) inputs, microbial activity, and carbon turnover. Rhizosphere processes remain poorly understood and the observation of key mechanisms for carbon transfer and protection in intact rhizosphere microenvironments are challenging. We deciphered the fate of photosynthesis-derived OC in intact wheat rhizosphere, combining stable isotope labeling at field scale with high-resolution 3D-imaging. We used nano-scale secondary ion mass spectrometry and focus ion beam-scanning electron microscopy to generate insights into rhizosphere processes at nanometer scale. In immature wheat roots, the carbon circulated through the apoplastic pathway, via cell walls, from the stele to the cortex. The carbon was transferred to substantial microbial communuties, mainly represented by bacteria surrounding peripheral root cells. Iron oxides formed bridges between roots and bigger mineral particles, such as quartz, and surrounded bacteria in microaggregates close to the root surface. Some microaggregates were also intimately associated with the fungal hyphae surface. Based on these results, we propose a conceptual model depicting the fate of carbon at biogeochemical interfaces in the rhizosphere, at the forefront of growing roots. We observed complex interplays between vectors (roots, fungi, bacteria), transferring plant-derived OC into root-free soil and stabilizing agents (iron oxides, root and microorganism products), potentially protecting plant-derived OC within microaggregates in the rhizosphere.
