“…Jerusalem artichoke has been used at . Such high yields of Jerusalem artichoke varieties are evidence of a positive response of this species to the applied sewage sludge, which finds confirmation in scientific literature [38][39]. The amount of yield obtained in the authors own research was comparable to the amount of yield obtained by Baldini et al [10].…”

The aim of our research was to assess the effectiveness of phytoextraction of heavy metals from sewage sludge by 'Rubik' and 'Albik' varieties of Jerusalem artichoke. The 6-year field experiment involved four levels of fertilization with sewage sludge at doses of 0,10,20,40, . The research evaluated the amount of Jerusalem artichoke yield as well as the uptake and use of heavy metals by the Jerusalem artichoke varieties.It was established that increasing doses of sewage sludge had significantly increased the yield of the Jerusalem artichoke varieties. Increasing doses of sewage sludge also had a significant effect on the increase in the content of heavy metals in aboveground parts of plants. The highest heavy metal uptake with the yield of the Jerusalem artichoke varieties was observed at a dose of 60 Mg DM • ha -1. Among the tested varieties of Jerusalem artichoke, Albik had higher yield, higher content and uptake of heavy metals, and greater recovery of these elements as compared to Rubik. Therefore, based on the obtained research results, Albik can be recommended for phytosequestration of heavy metals from sewage sludge amended soil.

“…Fatty acid composition varies in vegetable oils from different sources, mainly depending on cultivar, but also on ripeness and on the area of cultivation and climatic conditions [44]. Rapeseed oil has a well-balanced proportion of linoleic (C18:2; n-6) and α-linolenic acid (C18:3; n-3) at a 2:1 ratio [45].…”

We analysed physical and chemical properties of seeds and oils from different cultivars of winter rapeseeds ('Markus', 'Bios' and 'Feliks') that were cultivated using bio-gas natural manure (digestate) or with a commercially accessible Yara NPK 5014-28 (NPK) fertilizer, both of which were analyzed for element content. Seeds produced without use of fertilizers were taken as control. Prior to cold-pressing of oils, seeds were analyzed for fatty acid content. Cultivar 'Bios' breed with use of digestate showed a lower amount of oleic acid (C18:1), while the 'Feliks' cultivar had higher content of this fatty acid and lower amounts of linoleic acid (C18:2) as compared to respective controls. In the case of the application of NPK fertilizer, the increase in C18:1 was observed for the cultivars 'Markus' and 'Feliks'. In the latter the decrease in the content of C18:2 was observed as compared to control. The oils were analyzed monthly for photosynthetic pigment content and oxidative stability as well as color during a storage period of three months. Oils contained similar amounts of chlorophylls and carotenoids. Oils derived from seeds produced with the use of commercial NPK fertilizer were characterized with higher oxidation stability (induction time) as compared to digestate. Gradual darkening of the oils was observed. Statistical analysis (p<0.05) showed significant correlation between all the color parameters and term of measurements as well as with the applied fertilizer.

“…The absence of digestate phytoxicity was recorded also by other authors, but the conditions were only partially comparable with the present work. Actually, some studies were performed in vivo (Różyło et al, 2015), other applied different exposition periods (Alvarenga et al, 2015) or other kinds of digestate (Massaccesi et al, 2013). In a most recent study, the use of proper concentrations of digestate as a biofertiliser is encouraged, since it causes biostimulation under 20% dose (Pivato et al, 2015).…”

Abstract. Digestate represents a precious by-product in particular in agriculture, however its impact on the environment and human health is still unexplored. In this work, the toxicity of a pig slurry digestate was assessed through 7 ecotoxicity tests and considering 10 different endpoints. Besides, a synthetic index was applied to the outputs of the battery of tests for the environmental risk assessment, in order to evaluate the opportunity to use directly this kind of digestate in agriculture or to introduce an additional treatment. All the organisms were sensitive to digestate toxicity (EC 50 ranged from 14.22% for Cucumis sativum to 0.77% for Raphidocelis subcapitata). The physical-chemical features at the base of this toxicity seem to be the high content of ammonium, salinity, COD, phosphate and colour. The synthetic index showed that the digestate was very toxic and associated to an extremely high environmental risk. Thus a pre-treatment is needed to reduce its toxicity and environmental impact, whatever could 2 be its exploitation.
