“…Chlorella, compost, and vermicompost effectively improve their activities. Sulfur of 90–98% is known to exist in organic forms in soil environments, and sulfate ester occupies 30–75% organic S. ARS hydrolyzes this organic S and transforms it into inorganic forms [ 77 , 78 ]. Like the other enzymes, ARS was effectively activated by chlorella, vermicompost, and compost ( Figure S6e ).…”

Soil health deteriorates through the contamination and remediation processes, resulting in the limitation of the reuse and recycling of the remediated soils. Therefore, soil health should be recovered for the intended purposes of reuse and recycling. This study aimed to evaluate the applicability and effectiveness of several amendments to revitalize total petroleum hydrocarbon contaminated soils remediated by the landfarming process. Ten inorganic, organic, and biological amendments were investigated for their dosage and duration, and nine physicochemical, four fertility, and seven microbial (soil enzyme activity) factors were compared before and after the treatment of amendments. Finally, the extent of recovery was quantitatively estimated, and the significance of results was confirmed with statistical methods, such as simple regression and correlation analyses assisted by principal component analysis. The landfarming process is considered a somewhat environmentally friendly remediation technology to minimize the adverse effect on soil quality, but four soil properties—such as water holding capacity (WHC), exchangeable potassium (Ex. K), nitrate-nitrogen (NO3-N), available phosphorus (Av. P), and urease—were confirmed to deteriorate through the landfarming process. The WHC was better improved by organic agents, such as peat moss, biochar, and compost. Zeolite was evaluated as the most effective material for improving Ex. K content. The vermicompost showed the highest efficacy in recovering the NO3-N content of the remediated soil. Chlorella, vermicompost, and compost were investigated for their ability to enhance urease activity effectively. Although each additive showed different effectiveness according to different soil properties, their effect on overall soil properties should be considered for cost-effectiveness and practical implementation. Their overall effect was evaluated using statistical methods, and the results showed that compost, chlorella, and vermicompost were the most relevant amendments for rehabilitating the overall health of the remediated soil for the reuse and/or recycling of agricultural purposes. This study highlighted how to practically improve the health of remediated soils for the reuse and recycling of agricultural purposes.

“…The growth of ARS-producing bacteria is promoted by the presence of S in organic form in the soil and its activity may not be repressed by inorganic sulfate [25]. Soil amending with plant residues, wheat, fescue, and mustard, exhibiting different C:S ratios, revealed that residues with high S content significantly stimulated the population density of ARS-producing bacteria as compared to those with low S content [45]. Similar findings were also reported in [46], demonstrating that rhizosphere soil arylsulfatase activity was influenced by the fertilization regime; the application of large amounts of manure and mineral fertilizer resulted in higher soil arylsulfatase activity than mineral fertilizers or the unfertilized control.…”

Previous experiments have shown that the application of fertilizer granules containing elemental sulfur (S0) as an ingredient (FBS0) in durum wheat crops produced a higher yield than that produced by conventional ones (F), provided that the soils of the experimental fields (F vs. FBS0) were of comparable quality and with the Olsen P content of the field’s soil above 8 mg kg−1. In this experiment the FBS0 treatment took place in soil with Olsen P at 7.8 mg kg−1, compared with the F treatment’s soil with Olsen P of 16.8 mg kg−1, aiming at reducing the imbalance in soil quality. To assess and evaluate the effect of FBS0 on the dynamics of the rhizospheric bacteria in relation to F, rhizospheric soil at various developmental stages of the crops was collected. The agronomic profile of the rhizospheric cultivable bacteria was characterized and monitored, in connection with the dynamics of phosphorus, iron, organic sulfur, and organic nitrogen, in both the rhizosoil and the aerial part of the plant during development. Both crops were characterized by a comparable dry mass accumulation per plant throughout development, while the yield of the FBS0 crop was 3.4% less compared to the F crop’s one. The FBS0 crop’s aerial part showed a transient higher P and Fe concentration, while its organic N and S concentrations followed the pattern of the F crop. The incorporation of S0 into the conventional fertilizer increased the percentage of arylsulfatase (ARS)-producing bacteria in the total bacterial population, suggesting an enhanced release of sulfate from the soil’s organic S pool, which the plant could readily utilize. The proportion of identified ARS-producing bacteria possessing these traits exhibited a maximum value before and after topdressing. Phylogenetic analysis of the 68 isolated ARS-producing bacterial strains revealed that the majority of the isolates belonged to the Pseudomonas genus. A large fraction also possessed phosphate solubilization, and/or siderophore production, and/or ureolytic traits, thus improving the crop’s P, Fe, S, and N balance. The aforementioned findings imply that the used FBS0 substantially improved the quality of the rhizosoil at the available phosphorus limiting level by modulating the abundance of the bacterial communities in the rhizosphere and effectively enhancing the microbially mediated nutrient mobilization towards improved plant nutritional dynamics.

“…The p‐nitrophenol released during enzyme hydrolysis was determined with a spectrophotometer at a wavelength of 400 nm (Beijing Dongxun the Heavens and the Earth Instrument Co. Ltd, Beijing, China). Arylsulphatase activity was determined by measuring the release of nitrophenol from nitrophenol potassium sulphate as described previously (Chintala et al ., ; Piutti et al ., ).…”

Until recently, the relation between the microbial community structure and paddy soil enzyme functions has not been clear. Two types of paddy soil, located only 2 km apart and involved in the same field experiment, were used. We found a clear spatial effect on the bacterial community structure that could be related to the types of soil. The bacterial community structure was linked statistically to four indices of soil enzyme activity involving Gram‐positive and Gram‐negative bacterial phospholipid fatty acids (PLFAs), suggesting that the bacterial community has a more important role than fungi and other eukaryotes in modulating enzyme function in paddy soil. Redundancy analysis also showed that the two soil bacterial communities regulated soil enzyme activity with different effects. The α‐diversity of the bacterial community was positively associated with invertase activity, and negatively associated with the biomass normalized urease and arylsulphatase activities. In addition, the differences in soil enzyme activities were closely linked to dominant optimal taxonomic units (OTUs), most of which were phylogenetically related to enzyme producers from Planctomycetes, Proteobacteria and Chloroflexi with different 16S rRNA gene sequence similarity levels. Our results suggested that the enzyme function of paddy soil was linked to both the diversity and composition of bacteria in this study. Highlights We quantified the relation between the soil enzyme functions and bacterial community. Enzyme activities of paddy soil correlated with G+ and G− PLFAs. Bacterial α‐diversity was correlated statistically with paddy soil enzyme function. Species of Planctomycetes, Proteobacteria and Chloroflexi comprised the primary enzyme regulators.
