“…This was an expected result, since organic fertilizers with high C:N (16 for the one studied herein) and low inorganic N content are known to be useful to increase organic matter content. The application of organic wastes at similar rates to those used herein has been reported to increase [32,43,45,46] or prevent the decrease of SOM content [47], as is the case for T3. It should also be taken into consideration that the organic matter applied to calcareous soils is more stable, which also contributes to its increase [43].…”

Nitrate vulnerable zones (NVZs) are areas considered to be at high risk of water pollution due to an excess of nitrates and, according to European regulations, codes of good agricultural practice are to be implemented by farmers, such as reducing doses of the applied fertilizers, or the use of fertilizers that minimize nitrate leaching. In this work, the influence of organic fertilization with dried pig manure (DPM) as compared to mineral fertilization with ammonium sulfate nitrate with 3,4-dimethylpyrazole phosphate nitrification inhibitor was studied in a barley crop planted in a NVZ in Fompedraza (Valladolid, Spain). Organic and mineral fertilizers were applied at different rates (85, 133 and 170 kg N·ha −1 ·year −1 vs. 90 and 108 kg N·ha −1 ·year −1 , respectively) over a three-year period, in a randomized complete block design with six treatments and four blocks. DPM-based fertilization resulted in a 65% increase in crop yield as compared to the control soil, reaching 1800 kg·ha −1 for an application rate of 85 kg N·ha −1 ·year −1 . Higher DPM rates were found to increase the electrical conductivity and assimilable phosphorus, potassium, magnesium and organic matter contents, but did not lead to yield enhancements. Final nitrate and ammonium concentrations were lower than 10 mg·kg −1 and 20 mg·kg −1 , respectively, and no increase in soil salinity or heavy metal pollution was observed. DPM fertilization should be supplemented with small doses of inorganic fertilizers to obtain crop yields similar to those attained with mineral fertilization.

“…Copper addition increases the copper concentration in animal waste and manure [17,18]. Copper and other heavy metals show antimicrobial activity and are toxic toward embryos of Gobiocypris rarus and zebrafish [19,20,21]. Excessive Cu can also harm livestock and humans [22].…”

“…During the composting process, antibiotics show the complexation behavior and are usually degraded by microbes and heat decomposition. The combination of oxytetracycline with metal ions (OTC–metal complex), such as copper, significantly affects antibiotic transport and bioavailability during composting [19]. The formation of the OTC-metal complex becomes vital at higher concentrations [19].…”

Changes in Arsenic and Copper Bioavailability and Oxytetracycline Degradation during the Composting Process

et al. 2019

This research focuses on the effects of the composting process on oxytetracycline antibiotic degradation and the bioavailability of arsenic and copper. A compost experiment was conducted using cow and pig manure contaminated with oxytetracycline, and copper and arsenic salts. The changes in physicochemical properties, oxytetracycline concentration, and the germination index were measured. Copper and arsenic were estimated by sequential chemical extraction. We also detected the effects of compost properties, oxytetracycline concentration, and heavy metal (loid)s on the germination index through simple regression analysis. The results showed that the composting process positively and significantly affected heavy metal(loid)s bioavailability, oxytetracycline degradation, and the germination index. Oxytetracycline concentration declined in all treatments, and the decline was more evident in cows’ manure. The copper and arsenic bioavailable fraction decreased significantly, while the low bioavailability fraction increased. The germination index increased above 50%, which showed that the compost was free of toxic substances. This result also showed that the compost properties had the most significant impact on the germination index, and their regression had the highest R2 values (0.84 and 0.99) in the cow and pig manure treatments, respectively. In conclusion, the composting process provides an economical method for oxytetracycline degradation and heavy metal(loid)s bioavailability reduction.

Product maturity represents the efficiency of composting performance, and it calls for high attention in food waste composting. In this study, a 2(4-1) fractional factorial design method combined with well-controlled experiments was introduced to characterize the effects of system factors (i.e., C/N ratio, aeration rate, starting culture amount, and coal ash amendment) on product maturity of food waste composting. The compost maturity was synthetically evaluated by developing a Mamdani fuzzy rule-based inference system. Temperature index, O2 uptake rate, ammonium, OM loss, C/N ratio, and ash content were chosen as indicators of the fuzzy multicriterion maturity evaluation. Evaluation results of compost maturity for the eight experiment runs demonstrated that the proposed method is capable of evaluating the compost maturity in food waste composting. The effect analyses indicated that the starting culture amount and aeration rate contributed the most to the compost maturity in this study. The results could provide decision support for the process control in food waste composting management.
