“…It has been suggested that most of the DOM consists of extracellular polymers (mainly polysaccharides) released by anaerobic bacteria, and also metabolic products of their decomposition. Aliphatic acids and other simple molecules may also be present (Fletcher and Beckett, 1987). The IR of the DOM of Sw, C, C-S, and Sw-S samples were qualitatively similar to one another, although some important differences in peak intensities were observed (Fig.…”

“…Aliphatic acids and other simple molecules may also be present (Fletcher & Beckett, 1987). The SS band spectrum was 1720 cm -1 (C=O stretch of carboxyls and carbonyls of differing nature), 1550 cm -1 (amide II band, aromatic C vibration), and 1125 cm -1 (aliphatic alcohols), which were not detected in the soil (Figure 1).…”

SUMMARYThe application of sewage sludge is a concern because it may affect the quality of organic matter and microbiological and biochemical soil properties. The effects of surface application of sewage sludge to an agricultural soil (at 18 and 36 t ha -1 dry basis) were assessed in one maize (Zea mays L.) growing season. The study evaluated microbial biomass, basal respiration and selected enzymatic activities (catalase, urease, acid and alkaline phosphatase, and β β β β β-glucosidase) 230 days after sewage sludge application and infrared spectroscopy was used to assess the quality of dissolved organic matter and humic acids. Sewage sludge applications increased the band intensity assigned to polysaccharides, carboxylic acids, amides and lignin groups in the soil. The organic matter from the sewage sludge had a significant influence on the soil microbial biomass; nevertheless, at the end of the experiment the equilibrium of the soil microbial biomass (defined as microbial metabolic quotient, qCO 2 ) was recovered. Soil urease, acid and alkaline phosphatase activity were strongly influenced by sewage sludge applications.Index terms: basal respiration, biosolids, enzymatic activities, metabolic quotient, microbial biomass.(1) Received for publication in August 15, 2011 and approved in July 10, 2012.

“…Most of the water-soluble organic carbon (WSOC) in soil solution is composed of organic acids and soluble carbohydrates (Cook & Allan, 1992), and aliphatic acids and other simple molecules may also be present (Fletcher & Beckett, 1987). The immediate effect of the application of an organic material to soil is an increase in WSOC (Figure 1), which may pass into the soil solution, thus enhancing the native soluble organic fraction of the soil (Liu et al 2013).…”

The effects of applying sewage sludge (SS) to agricultural soil (at low rate\ud of 22.5, LRS, and at high rate of 45 t ha−1 dry basis, HRS) were monitored\ud over a 120-d experimental period. Total organic carbon (TOC), water-\ud soluble organic carbon (WSOC), alkali-soluble phenols, basal respiration, 10\ud specific enzyme activity, dehydrogenase activity (DH-ase), metabolic\ud potential (MP) and FDA-hydrolytic activity (FDA) were strongly increased\ud by both rates of SS applications. In the SS amended soil, about 70% of\ud the organic C added with the material remained at the end of the\ud experiment. Basal respiration increased with increasing SS doses. The 15\ud specific enzyme activity and the MP indicate an increase in the enzyme\ud activity in soil.\ud AQ10\ud The addition of SS led to higher values than the control of all the\ud tested parameters up to the end of the experimental period. The anti-\ud oxidant capacity (trolox equivalent antioxidant capacity, TEAC) was influ- 20\ud enced by SS addition only when applied at HRS. After 120 days only HRS\ud value of TEAC (5.13 mM g−1) was higher than control (4.09 mM g−1). The\ud pattern of TEAC did not enable any link to be established between\ud antioxidant capacity and both alkali-soluble phenols and basal respira-\ud tion in soil
