Production of biogas and utilization of the resulting digestates as fertilizers has been increasing in Europe in the last few decades. Depending on the feedstock used for the anaerobic digestion process, these organic fertilizers may be a source of different pollutants, such as trace metals. When applied to soils, digestates may influence the natural metal content and enhance the release of metals to the environment since they can be rich in different trace metals and are usually rich in dissolved organic matter. This study focused on investigating metal presence, seasonal variability of their soluble forms and crop uptake in a 2-year field experiment, using two different biogas digestates as fertilizers. The use of digestates as fertilizers was compared to cattle manure, mineral fertilizer and a control without fertilizer addition, with respect to the presence and distribution of the trace metals Cd, Cu, Zn, Ni, Cr, Mn, and Mo, as well as Al in the soil and plant. The results of the study showed that both biogas digestates have caused a 10-20% increase in the total soil concentration of Ni, Cd and Cr compared to control plots without fertilizer addition. Application of biogas digestates had only a minor effect on metal uptake in plants. Overall, the selected application rate of 100 kg/ha of plant available nitrogen has had little effect on plant metal uptake and crop quality and the use of biogas digestates was comparable to the use of animal manure.

“…We have used these background reference concentrations due to the lack of local element background information and also to have a uniform scale for all elements studied, because some emerging contaminants such as Se, Sb, Sn, and Tl have no reported background value in sediments (Birch , 2017). The contamination level accroding to the CF value may be classified as follows: low degree (CF<1), moderate degree (1≤CF<3), considerable degree (3≤CF<6), and very high degree (CF≥ 6) (Luo et al, 2007;Shaheen et al 2017a;Ghosh et al, 2018).…”

“…For example, elements such as V, Cr, and Fe are reported to be closely associated and usually co-exist in sediments/soils(Edwards et al 1995;Aide 2005;Rinklebe et al, 2016;Shaheen and Rinklebe 2017).Also, the positive corelations between the elements (except for Hg) and sediment organic matter (r = 0.64 -0.82; P ≤ 0.05) point to the association of those elements with sediment organic carbon and their possible distribution in the organic fraction assuggested byShaheen and Rinklebe (2014) for Cu and Zn, and byShaheen et al (2017b) for As. Also,Shaheen et al (2017a) found that the total concentrations of Al, Cd, Cr, Cu, Fe, Mn, Ni, and Zn were higher in a soil rich in organic carbon than in an adjacent soil poor in organic carbon. Moreover,Zhou et al (2018) supported the crucial role of OM in the distribution…”

“…Recently, remediation technologies for potential toxic element contamination in soil have been developed, such as chemical immobilization [15,16,17], water management [18,19,20], chemical washing [21,22], and bioremediation [23,24,25]. In situ chemical immobilization is an especially effective method to control the availability of potentially toxic elements [26,27].…”

Cadmium (Cd) in paddy soil is one of the most harmful potentially toxic elements threatening human health. In order to study the effect of lime combined with intermittent and flooding conditions on the soil pH, Cd availability and its accumulation in tissues at the tillering, filling and maturity stages of rice, as well as enzyme activity and the microbial community in contaminated soil, a field experiment was conducted. The results showed that liming under flooding conditions is a more suitable strategy for in situ remediation of Cd-contaminated paddy soil than intermittent conditions. The availability of Cd in soils was closely related to the duration of flooding. Liming was an effective way at reducing available Cd in flooding soil because it promotes the transformation of Cd in soil from acid-extractable to reducible fraction or residual fraction during the reproductive growth period of rice. Compared with control, after liming, the concentration of Cd in brown rice was reduced by 34.9% under intermittent condition while reduced by 55.8% under flooding condition. Meanwhile, phosphatase, urease, and invertase activities in soil increased by 116.7%, 61.4% and 28.8%, and 41.3%, 46.5% and 20.8%, respectively. The high urease activity in tested soils could be used to assess soil recovery with liming for the remediation of contaminated soil. Soil microbial diversity was determined by the activities of soil acid phosphatase, urease and available Cd by redundancy analysis (RDA). The results indicated that the problem of Cd-contaminated paddy soil could achieve risk control of agricultural planting by chemical treatment such as lime, combined with various water regimes.
