The main purpose of this work was to identify the role of soil humic acids (HAs) in controlling the behavior of Cu(II) in vineyard soils by exploring the relationship between the chemical and binding properties of HA fractions and those of soil as a whole. The study was conducted on soils with a sandy loam texture, pH 4.3-5.0, a carbon content of(More)
Sewage sludge is waste for which the most positive outlet must be sought whilst, at the same time, making use of its qualities. In view of its organic matter and other nutrients content, it may be thought that the best system is to use it for agricultural purposes, although the load of heavy metals it may bear with it proves to be the main obstacle(More)
A spent mushroom substrate (SMS) was mixed with wheat straw (WS) in three proportions, C1 (2:1), C2 (4:1), and C3 (6:1), and composted for 90 days in static piles with periodic turning to ensure adequate aeration. Samples from each pile were collected periodically (after 0, 30, 60, and 90 days), and the humic acid-like fractions (HAs) were isolated to(More)
The purposes of this study were to determine the Cu(II) binding behavior of humic acids (HAs) isolated from biosolid compost (BI), leonardite (LE), a metal-contaminated soil, and the soil remediated with either BI or LE in relation to their structural properties, and to explore the role exerted by the HA fractions in controlling soil Cu(II) bioavailability.(More)
This study seeks to determine the impact of copper-based fungicides on the respiration of vineyard soils. The ISO-17155 is an international standard recommended for monitoring soil quality by the evaluation of the effects of pollutants on soil microbial activity. Respiration curves and derived parameters [i.e., basal respiration (RB), substrate-induced(More)
The objectives of this work were to (a) investigate the short-term effects of applications of mineral fertilizer, municipal solid waste (MSW) compost, and two sewage sludges (SSs) subjected to different treatments (composting and thermal drying) on microbial biomass and activity of soil by measuring microbial biomass C, adenosine 5′-triphosphate content,(More)
Sphagnum peat has been found to efficiently remove heavy metals, oil, detergents, dyes, pesticides and nutrients from contaminated waters since its major constituents, i.e., unesterified polyuronic acids, cellulose, and fulvic and humic acids (HA), show functional groups (e.g., alcohols, aldehydes, carboxylic acids, ketones and phenolic hydroxides) which(More)
Many sites inside a protected area in Apulia region (Italy) have been contaminated with heavy metals (Cd, Cr, Cu, Ni, Pb, Zn) because an inadequate disposal of a variety of wastes with different sources of origin. As first measure in-situ phytoremediation techniques were evaluated using only the natural plants that grew wildly on the contaminated soils, in(More)
A long-term field experiment utilising barley received four different treatments prior to sowing: municipal solid waste (MSW) compost at either 20 t ha (C20) or 80 t ha (C80); cow manure (MA) at 20 t ha; mineral fertilizer (MIN) or NPK (400 kg ha); and NH4NO3 (150 kg ha). The effects of these applications on soil enzyme activities and microbial biomass at(More)
