“…The results of the present study indicate that application of sludge can increase or maintain soil fertility. Soil organic matter and N and P contents following sewage sludge application were significantly higher than after application of chemical fertilizer (Table 2), and this is in accord with previous reports (Su et al 2007;Roig et al 2012;Wu et al 2012). Large amounts of nutrients such as organic matter and organic and inorganic N and P in the sludges as shown in Table 1, especially the domestic sewage sludge, may improve and maintain soil quality (Table 2).…”

The effects of repeated application of two types of sewage sludge, domestic and industrial (petrochemical, PSS) sludges, into paddy fields over a 5-year period on the soil properties and microbial ecology were studied and compared with conventional NPK fertilizer application. Soil organic matter and total nitrogen contents were significantly higher in the two sludge treatments than that in fertilized plots after 5 years. Soil concentrations of potentially toxic metals were low after 5 years of both sludge treatments, but the polycyclic aromatic hydrocarbons (PAHs) showed differences between the two sludge types. Concentrations of high-molecularweight PAHs were significantly higher (p < 0.05) in the petrochemical sludge treatment than the domestic sludge treatment or the fertilizer control, although the total concentrations of 16 types of PAH in the petrochemical sludge treatment were only slightly higher than in the domestic sludge treatment and the control. The biological toxicity of soil dimethyl sulfoxide extracts from the petrochemical sludge treatment was also significantly higher (p < 0.05) than those from the fertilizer control and the domestic sludge treatment when evaluated using Photobacterium phosphoreum T3. Both types of sewage sludge increased soil microbial activity, but only the petrochemical sludge led to enrichment with specific PAH degraders such as Mycobacterium, Nocardioides, and Sphingomonas.

“…De acordo com Nascimento et al (2004), a presença de metais pesados constitui uma das principais limitações ao uso do lodo na agricultura, sendo que, o aumento desses elementos em solos e em plantas tem sido constantemente observado (Singh & Agrawal, 2007;Roig et al, 2012;Nogueira et al, 2013;Bramryd, 2013). De modo geral, as concentrações de metais encontradas no lodo são bem maiores que as naturalmente encontradas em solos, razão pela qual há necessidade de avaliação dos riscos associados ao aumento desses elementos no ambiente em decorrência da aplicação deste resíduo.…”

Objetivou-se, com este trabalho, avaliar os teores de metais pesados no solo e em plantas de girassol adubadas com doses de lodo de esgoto. O experimento foi desenvolvido em Cambissolo Háplico, no período de abril a setembro de 2011. Os tratamentos, distribuídos no delineamento em blocos casualizados, com quatro repetições, corresponderam a um tratamento com adubação química e cinco doses de lodo de esgoto aplicadas com base nos teores de N do resíduo e na exigência de N do girassol (0; 4,84; 9,68; 19,36 e 29,04 t ha-1, em base seca). Os teores de Zn no solo e na planta foram maiores nos tratamentos com a aplicação de lodo de esgoto quando comparados com a adubação química. A aplicação de lodo de esgoto resulta em aumento nos teores de Cu, Ni e Pb no solo e não apresenta influência sobre os teores de Zn, Fe, Mn, B, Cd e Cr neste substrato. Por outro lado, na planta, com o aumento da dose de lodo de esgoto, houve aumento dos teores de Zn, Cu e Mn e redução do teor de Pb.

“…This material can be a useful source of nutrients for the soil environment by turning wastes into valuable resources (Ghoniem, 2007;Dawi, 2014) that contained total N ranging from 1.5% in air-dried lime treated biosolids to 7.5% in liquid mesophilic anaerobic digested biosolids (Rigby et al, 2016). On the other hand, increasing doses of municipal solid wastes could be associated with sharp decrease in soil NO3-N and as a result inhibition of plant growth (Giannakis et al, 2014) or soil properties may not improve or even worsen beyond 40 t ha -1 of sewage application (Roig et al, 2012).…”

Article Info Received : 08.08.2016 Accepted : 07.11.2016 A field experiment was conducted in the Experimental Research Farm of Omdurman Islamic University, Sudan to determine short-term effect of irrigation intervals (7 and 10 days) and sun-dried or composted sewage sludge, recommended mineral fertilizer on straw dry matter yield (SDMY) and N, P and K content of fodder sorghum and soil properties. In the 7 and 10 days irrigation intervals, composted, sun-dried sludge and mineral fertilizer have significantly increased SDMY over the control by 51, 98, 67 and 78, 19, 33%, respectively. Apparent N use efficiency (ANUE) in composted and sun dried plots irrigated at either 7 or 10 days was 9 -36 and 16 -74%, respectively. Reducing the irrigation interval has significantly increased salinity by 13%. Increasing irrigation interval has decreased bulk density by 5%. It could be concluded that, application of composted sludge is a useful practice for improvement of soil properties and consequent yield increase.
