“…Haney et al [17] found that in 0-30 cm soils increased with application rate, presumably as a result of higher wheel traffic required to land-apply at greater biosolids rates, but not with application duration at the lowest rate [17]. Results from the current study and previous reports are consistent with the variability in soil responses found in other studies on surface-applied biosolids which have reported no effects or increased [12,32,33,40] or decreased due to biosolids application [24,27].…”

“…Here, surface application rates were positively correlated with SOC and total N in the top 15 cm soil layer, somewhat deeper than other studies reporting that SOC and N gains are limited to the top <10 cm of soils [24][25][26][27]. The current results underscore the fact that the effects of application rate and duration on SOC and total N stocks can be highly variable and depend on biosolids-specific composition as well as site-specific factors (e.g., soils, management) [5,7,28].…”

“…Other field studies on repeated surface-applied biosolids also have found increases in SOC [4,12,[24][25][26][27]29] and found that increases are positively correlated with application rate [4,25]. Site-specific increases in SOC have been reported for application rates as low as 2 to 7 Mg ha −1 yr −1 [24,30].…”

Mid-to long-term impacts of land applying biosolids will depend on application rate, duration, and method; biosolids composition; and site-specific characteristics (e.g., climate, soils). This study evaluates the effects of surface-broadcast biosolids application rate and duration on soil organic carbon (SOC) stocks, soil aggregate stability, and selected soil hydraulic properties in a municipally operated, no-till forage production system. Total SOC stocks (0-45 cm soil) increased nonlinearly with application rate in perennial grass fields treated for 8 years with 0, 20, 40, or 60 Mg of Class B biosolids (DM) ha −1 yr −1 (midterm treatments). Soil organic C stocks in long-term treatment fields receiving 20 years of 20 Mg ha −1 yr −1 were 36% higher than those in midterm fields treated at the same rate. Surface-applying biosolids had contrasting effects on soil physical properties. Soil bulk density was little affected by biosolids applications, but applications were associated with decreased water-stable soil aggregates, increased soil water retention, and increased available water-holding capacity. This study contrasts the potential for C storage in soils treated with surface-applied biosolids with application effects on soil physical properties, underscoring the importance of site-specific management decisions for the beneficial reuse of biosolids in agricultural settings.

“…Additional soil variables were measured to identify the main drivers of the effects tillage and organic amendment on BGa in the second sampling period. These variables, measured in air-dry sieved soils (<2 mm) were: organic matter content (SOM) (measured with hot hydrogen peroxide), which is related to soil compactibility [20]; electric conductivity (EC) and pH determined in 1:2.5 soil:water suspensions; the Middleton's dispersion ratio defined as [(% dispersed silt + clay after mild dispersion)/(% dispersed silt + clay after drastic dispersion)] × 100 [21] as a rapid measure of structure stability; and water stable aggregates, measured according to Kemper and Rosenau [22] (Table 1). …”

Influence of Tillage Practices, Organic Manures and Extrinsic Factors on β-Glucosidase Activity: The Final Step of Cellulose Hydrolysis

β-glucosidase is a key enzyme in the C-cycle, and its activity is strongly influenced by soil management practices and by extrinsic factors such as weather conditions. However, the variability of β-glucosidase activity (BGa) over time and how this variability is affected by tillage and organic fertilization remain poorly elucidated. We investigated how contrasting tillage practices (zero, minimum, conventional or deep) and organic amendment application (dairy cattle slurry or green compost) govern BGa. Strong correlations (r = −0.98; p < 0.001) were found between BGa and preceding cumulative rainfall for soil without crops. Under cropped soil conditions, BGa was 53% greater under zero and minimum tillage than under ploughed treatments (p < 0.05) six years after their applications. These differences could be explained by associated effects of tillage on organic matter content, electrical conductivity and water stable aggregates. The separated organic residue experiment showed that BGa was 36% greater in soil amended with slurry than in soil amended with compost (p < 0.05) five years after their applications. Finally, the response ratio of BGa was calculated in order to study the effect size of each treatment at each sampling period. This simple strategy mitigated the variation on BGa measurements between two sampling periods, and may be applied in future studies to improve the interpretation of other potential soil quality indicators that are sensitive to seasonal changes.

“…Biosolids significantly reduced soil bulk density and increased soil porosity at flowering and maturity (Figure 2). This was primarily attributed to the organic matter that binds flocculating soil particles to form stable aggregates, thus improving soil structure and increasing total volume of macro-and micro pores (Mariscal-Sancho et al 2011). Cardelli et al (2017 also reported an increased biological activity.…”

In a two-year pot experiment, the effect of five growing media on the growth, flowering, decorative value of Pelargonium peltatum cv. Maxime as well as on their uptake of the nutrients and heavy metals were studied. The media were prepared from four composts (made from: sewage sludge 70% or 35%, potato pulp 35%, straw 30% or sawdust 30%) and peat in 1:1, V:V ratio. In the 1<sup>st</sup> year of research 7-month-old composts and in the 2<sup>nd</sup> year 18-month-old composts were used. Plants cultivated in 7-month-old composts showed better growth-related parameters, created more inflorescences and were more decorative than those cultivated in 18-month-old ones. The medium with compost consisting of 70% sewage sludge and 30% straw gave the best results. Composts application increased nutrients and heavy metals content in pelargonium leaves. Heavy metals content was definitely lower than the value considered toxic to plants.
