“…An increase in protein content along with an increase in nitrogen fertilisation was also found in other studies [58,65,66]. An increase in protein content after digestate from biogas plants was also found in winter wheat [41]. The significant differences in protein content depending on the cut date were observed only after application of the digestate.…”

The aim of this study was to assess the effect of a three-year application of digestate from an agricultural biogas plant on the physicochemical properties of highly acidic pHKCl 4.4 ± 0.23, silty loam soils with low macronutrient content and on the yield and nutritional value of switchgrass (Panicum virgatum L.) biomass harvested for green fodder. The experiment included the following treatments: (1) O (control)—no fertilisation, (2) NPK—mineral fertilisation with (in kg ha−1) 150 N, 53.0 P and 105 K, (3) biogas digestate at 30 m3 ha−1 and (4) biogas digestate at 60 m3 ha−1. The higher application rate of biogas digestate significantly reduced soil acidity to pHKCl 4.9 ± 0.18 and improved its sorption properties. It also increased the soil organic matter content from 5.6 ± 0.21 to 6.4 ± 0.22 g Corg kg−1 and of K and Zn. The higher level of biogas digestate significantly increased switchgrass yield to 5.15 ± 0.26 t ha−1. The lower application rate of biogas digestate resulted in forage yield of 4.30 ± 0.20 t ha−1 comparable to that obtained after mineral fertilisation (4.33 ± 0.22 t ha−1). Following application of mineral fertilisers and the higher level of biogas digestate, the number of panicles per plant (150 ± 2.49–157 ± 0.6.17), panicle height (107 ± 1.98–114 ± 2.08), crude ash content (61.2 ± 0.43–65.5 ± 0.38) and protein content (106 ± 0.59–92 ± 1.11) in the switchgrass biomass from the first cut were higher than in the case of unfertilised soil (110 ± 3.81, 93 ± 1.32, 55.5 ± 0.40, 80.3 ± 0.37). The use of mineral fertilisers and biogas digestate increased the content of protein, P and Mg in biomass from the second cut. The results suggest that the use of digestate improved the physicochemical properties of highly acidic soil and increased the yield of switchgrass forage without diminishing its nutritional value.

Microplastics (MPs) occur widely in terrestrial ecosystems. However, information on the interaction of MPs with metals in terrestrial ecosystems is lacking in the literature. The present study investigated the effects of two types of MPs (high-density polyethylene (HDPE) and polystyrene (PS)) with different dosages (i.e., 0, 0.1%, 1%, and 10%) on the uptake and effects of Cd in maize plants grown in an agricultural soil. Results showed that addition of Cd at a 5 mg/kg caused inhibited plant growth and resulted in high Cd accumulation in plant tissues. Polyethylene alone showed no significant phytotoxic effects, but a high-dose of HDPE (10%) amplified Cd phytotoxicity. Polystyrene negatively affected maize growth and phytoxicity further increased in the presence of Cd. Both HDPE and PS caused soil diethylenetriaminepentaacetic acid (DTPA)-extractable Cd concentrations to increase but did not significantly affect Cd uptake into plant tissues. In the soil without Cd addition, HDPE decreased soil pH, while PS did not significantly alter soil pH. However, in the soil spiked with Cd, both HDPE and PS increased pH. Overall, impacts on plant growth and Cd accumulation varied with MP type and dose, and PS induced substantial phytotoxicity. In conclusion, co-occurring MPs can change Cd bioavailability, plant performance, and soil traits. Our findings highlight the ecological impacts that could occur from the release of MPs into soil.

“…The source of mineral mining waste (MS) was carbonate mudstones, which due to geological time belongs to carboniferous roof rocks, bottom rocks, or interlayers of exploited coal seams in a coal mine located in the Lublin region of Poland. A detailed parameters of the wastes and soil used for testing is provided in Table 1 and broader description is available in our previous publications (Różyło et al 2015;Różyło et al 2017).…”

“…Both BD and MS contain huge amounts of OM (total organic carbon (TOC) at 35.6-63.3% DW and 28.1% DW, respectively) (Stefaniuk et al 2015, Różyło et al 2017. In addition to improving the physicochemical properties of the soil, OM also stimulates the growth of the microorganisms and increases the enzymatic activity of the soil.…”

“…In order to prevent negative and irreversible changes occurring in the soil environment, the application of waste materials to the soil must be preceded by the widest testing spectrum that is possible. Różyło et al (2015), Stefaniuk et al (2015), and Różyło et al (2017) conducted chemical and toxicological tests and demonstrated that the application of BD and carboniferous rock to soil disturbs the ionic balance of soil, and they also showed that there was a negative effect of the application of waste materials on certain organisms (e.g., reduction in luminescence of Vibrio fischeri following the application of carboniferous rock (Różyło et al 2015). This suggests that the properties of BD and carboniferous rock added to the soil separately or in combination have a significant effect on the growth of microorganisms and on the enzymatic activity of soil microorganisms.…”

The intensity of organic matter transformation in soil may be subject to various factors, especially to the previously applied non-standard chemical-based fertilizers. The objective of study was to assess the number of selected groups of microorganisms and enzymatic activity in soil after waste utilization. Biogas digestate (1.5 and 3.0%) and mineral mining waste (10 and 20%) were added to podzolic soil. The results demonstrated that the application of these wastes increased the number of microorganisms in the soil. 20% mineral mining waste provided the most favorable conditions for the development of oligotrophs and copiotrophs, whereas 3% biogas digestate most positively affected the total number of bacteria. This waste increased soil enzyme activity proportionally to the applied concentration. The highest activity was obtained for 1.5% biogas digestate. The number of oligotrophs, copiotrophs, and proteolytic microorganisms correlated positively with pH, organic carbon content, total nitrogen, and micronutrients present in the soil, while negatively with phosphorus content. The activity of the majority of enzymes was positively correlated with the content of mineral nitrogen, phosphorus, and potassium. In this study, we were not able to demonstrate a negative correlation between the content of heavy metals and the number of microorganisms in the soil. These results suggest that biogas digestate and mineral mining waste can be used in agricultural practice to improve microbial activity of the subsoil with a large reserve of safety for the soil environment.
