“…Similar observations were made by Mazzoncini et al (2015), who found that syringic acid was dominant in winter wheat and its content was significantly increased by organic fertilization (compared to conventional cultivation). Also, Hung et al (2011) found syringic acid to be the main compound in the free phenolic alcoholic extracts of the wheat meal representing 77.0% of the total amount of detected free phenolic compounds.…”

The food industry faces the problem of soil contamination and consequently the deterioration of the quality of plant products. Here, we present a study on evaluation of the effect of fertilization with sewage sludge (SL) with varying, rates of biochar (BC 2.5, 5 and 10% of DW) on yield quality and the accumulation of heavy metals in wheat grains. The greatest grain yield with the highest content of protein and gluten as well as the highest total content of phenols and flavonoids, was obtained when SL+5%BC fertilization was applied. The addition of 5%BC and 10%BC to SL resulted in the greatest increase in the antioxidant capacity of grain. Among phenolic acids, syringic acid was found in the largest amount in grain in the SL+2.5%BC treatment. A significant decrease in Pb accumulation in wheat grain after application of SL+5%BC and a successive decrease in Al content with increasing BC addition were observed. To increase the quality of wheat grains and to reduce the bioaccumulation of harmful elements after the application of biochar to the soil is important in the context of food safety and health of humans especially in food production on acidic and/or contaminated soils.

“…For comparison, ChP of the grain of six spelt wheat cultivars can have a value ranging from 29.8 to 91.4 extract EC 50 mg DW ml -1 (bound) ). In the study by Mazzoncini et al (2015), the fertilization system (organic/conventional) did not significantly affect the antioxidant power (DPPH and ABTS) of white flour, whereas the antioxidant power in bran showed higher values under the organic system relative to the conventional system. The rate of fertilizer also has a significant influence on the antioxidant power.…”

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.

“…3 and Table 4). Considering the general low quality of organic wheat grain, it is quite usual for the farmers to gain a substantial increase of the selling price for slight improvement of the grain protein content (Mazzoncini et al, 2015), so even a small increase should not be disregarded in terms of net income for the farmers.…”

“…In conventional agriculture, the use of split application of mineral N fertilizers has been shown to increase fertilization effi ciency and the harvest index of wheat (Blandino et al, 2015;FuertesMendizábal et al, 2010). In organic farming, side dressing fertilization is not commonly used and the management of N fertilization is normally based on: (i) increasing the presence of legumes in the crop rotation (Th omsen et al, 2013), (ii) broadcasting organic compounds before sowing (Mazzoncini et al, 2015;Petersen et al, 2013) and (iii) adopting cereal-legume intercropping (Pelzer et al, 2012). An improvement in the use of legume crops represents the most promising option for the achievement of farm N self-suffi ciency (Amosse et al, 2014;Farneselli et al, 2013).…”

Nitrogen Fertilization Strategies for Organic Wheat Production: Crop Yield and Nitrate Leaching

et al. 2016

Nitrogen fertility management represents a crucial aspect for common wheat (Triticum aestivum L.) production, particularly when we deal with organic agriculture. Th is study was conducted to determine the eff ect of fi ve N fertilization strategies on yield, grain protein content, and N leaching risk. In a 3-yr fi eld experiment, a faba bean/wheat temporary intercropping (TIC) and four fertilization treatments with extra-farm N sources were compared. Extra-farm N sources were represented by blood meal (BM) and roasted leather (RL) (broadcast all-at-once at seeding or split into one-half at seeding and one-half at tillering in a side-dressing application). Unfertilized and mineral fertilized controls were included. Th e eff ect of the legume on TIC wheat N uptake was always positive while dry weight accumulation and yield were generally poorly aff ected. Regardless of the broadcasting method, BM treatments generally showed a slightly higher yield and grain protein content compared to wheat fertilized with roasted leather (this was also confi rmed by fertilizer release effi ciency). Th e risk of N leaching was maximum at the onset of drainage (i.e., during the fi rst phase of crop growth), so using organic fertilizers at preseeding stage appeared to be a very risky practice, especially if quick-N-releasing ones are used. Splitting the organic fertilizer rate avoided a large amount of mineralized N to be leached in the watershed during the critical stage of drainage onset. Th e TIC was the best option in terms of environmental preservation, and assured a constantly higher grain protein content compared to the other organic fertilization treatments.
