“…The Northwestern part is the predominantly agrarian community, and a moderate to high pattern of K might be due to the application of NPK and muriate of potash. This is coherent with other studies such as Madaras and Lipavský 72 , Madaras et al 73 , Pulkrabová et al 74 , Asare et al 75 who observed using muriate of potash and NPK for soil stabilization and treatment resulted in high K content in the soil. Potassium enrichment in the northwestern part of the spatial distribution map might be due to the usages of potassium-based fertilizers such as potassium chloride, potassium sulphate, potassium nitrate, sylvinite, and kainit to increase the k content of deficient soil.…”

Soil pollution is a big issue caused by anthropogenic activities. The spatial distribution of potentially toxic elements (PTEs) varies in most urban and peri-urban areas. As a result, spatially predicting the PTEs content in such soil is difficult. A total number of 115 samples were obtained from Frydek Mistek in the Czech Republic. Calcium (Ca), magnesium (Mg), potassium (K), and nickel (Ni) concentrations were determined using Inductively Coupled Plasma Optical Emission Spectroscopy. The response variable was Ni, while the predictors were Ca, Mg, and K. The correlation matrix between the response variable and the predictors revealed a satisfactory correlation between the elements. The prediction results indicated that support vector machine regression (SVMR) performed well, although its estimated root mean square error (RMSE) (235.974 mg/kg) and mean absolute error (MAE) (166.946 mg/kg) were higher when compared with the other methods applied. The hybridized model of empirical bayesian kriging-multiple linear regression (EBK-MLR) performed poorly, as evidenced by a coefficient of determination value of less than 0.1. The empirical bayesian kriging-support vector machine regression (EBK-SVMR) model was the optimal model, with low RMSE (95.479 mg/kg) and MAE (77.368 mg/kg) values and a high coefficient of determination (R2 = 0.637). EBK-SVMR modelling technique output was visualized using a self-organizing map. The clustered neurons of the hybridized model CakMg-EBK-SVMR component plane showed a diverse colour pattern predicting the concentration of Ni in the urban and peri-urban soil. The results proved that combining EBK and SVMR is an effective technique for predicting Ni concentrations in urban and peri-urban soil.

“…However, none of the investigated antibiotics were detected in soils amended with digested and stored sewage sludge in southern Sweden, which indicates that long-term sludge amendment has not led to accumulation of these antibiotics in the soils [32]. In the Czech Republic, the application of sewage sludge represented a negligible risk for antibiotics in the treated soils [33]. Compared to other countries, the restricted and low use of antibiotics and/or wastewater treatment procedure can be considered as the reasons for the low antibiotic contents in the sludge-treated soils.…”

“…Numerous studies have demonstrated that application of animal manure or sewage sludge will improve soil quality [35,36]. Nevertheless, organic amendments will also turn soil into a sink of antibiotics and antibiotic resistance [33,37]. The application of organic fertilizers improved soil physicochemical properties, which will promote the adsorption of antibiotics in soil.…”

Recycling of organic wastes in agricultural ecosystems to partially substitute chemical fertilizer is recommended to improve soil productivity and alleviate environmental degradation. However, livestock manure- and sewage sludge-derived amendments are widely known to potentially carry antibiotic residues. The aim of this study is to investigate how substituting organic fertilizer for chemical fertilizer affects soil quality and antibiotic residues in agricultural soil, as well as their tradeoffs. A field experiment was conducted with the different treatments of pig manure and sewage sludge as typical organic fertilizers at equal total nitrogen application rates. The analysis of variance showed that the increments on the levels of residual antibiotics in the agricultural soils due to organic substitution for chemical fertilizer by pig manure and sewage sludge were observed. The antibiotic residues ranged from 13.73 to 76.83 ng/g for all treatments. Partial organic substitution significantly increased the sequestration of antibiotics in agricultural soil by 138.1~332.5%. Organic substitution will also significantly improve soil quality, especially for nutrient availability. Based on principal component analysis, organic substitution will strongly affected soil quality and antibiotic contamination. Pearson’s correlation showed that soil physicochemical properties had significant correlations with concentrations of antibiotics in soil, indicating organic fertilizers can promote the persistence of antibiotics in soil by modifying soil quality. To balance the benefits and risks, appropriate management practices of organic fertilizers should be adopted.

“…Jones et al (2014) surveyed 28 wastewater treatment works in Great Britain for over a period of 12 months and contaminants such as trace metals, pharmaceuticals, polycyclic aromatic hydrocarbons (PAHs), 'emerging' and regulated organic pollutants were detected in at least some of the sludges sampled. Many investigations documented that the regular long-term application of SS can result in the regular increase of hardly degradable organic pollutants in soils (Singh and Agrawal 2008;Pulkrabová et al 2019). Major limitation of the SS use in agriculture is a potential release of heavy metals from the SS and their accumulation to toxic levels in the topsoil (Hanč et al 2007).…”

The role of low molecular weight organic acids in the release of phosphorus from sewage sludge-based biochar

Low molecular weight organic acids (LMWOAs) are common and abundant compounds in the environment, responsible for the release of the nutrients from rhizosphere into the soil solution and, therefore, facilitating the availability of these nutrients for plants. Sewage sludge biochar (SSB) is considered to be a potential source of phosphorus (P) in soil. In this context, the efficacy of twelve LMWOAs in releasing SSB-bearing P was tested in a laboratory extraction experiment. Moreover, the potential effects of (i) biochar pyrolysis temperature (varying from 220°C to 620°C) and (ii) other elements in SS, to estimate the P bonds attacked predominantly by the LMWOAs, were also assessed. The results revealed citric acid was the most effective extraction agent enhancing the mobility of the SSB-derived P. P release was strongly affected by biochar pyrolysis temperature (the highest P release was from the 320°C biochar, significant at p < 0.05). Moreover, the results showed that P was released preferably from Fe-P bearing compounds in SS. Citric acid was recorded as less effective at releasing other nutrients, such as Ca, Mg, K, indicating the exceptional performance of citric acid in P release from biochar without substantial effect on the other nutrients.
