“…Similar results were reported by Marques et al (2007). However, Bertoncini et al (2004), applying a dose equivalent of 388 t ha -1 sludge to pots containing samples of Red Latosol (Oxisol), found negative effects on the cane quality, e.g., an increase in the reducing sugar content and reduction in the fiber quantity. In this case, aside from the fact that the experiment was conducted in pots and not in field and the high sludge dose (far above the permitted for agricultural use), the cane had probably not reached maturity at the time of cutting, because a late variety, RB 72-454, was used, but harvested only 10 months after planting.…”

“…The reason is that although this use is one of the most feasible alternatives from a technical and economic standpoint, there are still many doubts among farmers and sewage system managers as to the best fertility management of sludge-treated soil (Abreu Junior et al, 2005, besides concerns about environmental contamination, e.g., heavy metals, toxic organic compounds and/or pathogens (Bertoncini et al, 2004;Abreu Junior et al, 2005Camilotti et al, 2009). …”

SUMMARYThe use of sewage sludge in Brazilian agriculture was regulated by the resolution no. 375 Conama, in 2006. However, there is a lack of research to adequate the mineral N and P fertilizer doses to be applied in agricultural fields treated with this residue. In a field experiment, the effects of application rates of sewage sludge and mineral N and P fertilizers on the productivity and technical characteristics of the cane-plant and first ratoon (residual effect) crops were evaluated. Four doses of sewage sludge (0, 3.6, 7.2 and 10.8 t ha -1 , dry base), of N (0, 30, 60 and 90 kg ha -1 ) and of P 2 O 5 (0, 60, 120 and 180 kg ha -1 ) were combined in a factorial and laid out on randomized block design, a with two replications. To evaluate the residual effect of the sludge, 120 kg ha -1 N and 140 kg ha -1 of K 2 O were applied in all plots. Sludge application at cane planting, with or without N and/or P fertilizer increased the stalk yield from 84 up to 118 t ha -1 , with no alteration in the sugarcane quality, compared with the application of NPK fertilizer alone, resulting in a stalk yield of 91 t ha -1 . The study of the response surface for stalk yield on lowfertility soil was the basis for a recommendation of mineral N and P fertilizer doses for sugarcane implantation as related to sewage sludge application rates. It was also concluded that a sludge application of 10.8 t ha -1 , which is the sludge dose established based on the N criterion according to the resolution Conama n o 375, could a) reduce the use of mineral N by 100 % and of P 2 O 5 by 30 %, with increments of 22 % in stalk yield, as a direct effect of sludge application to cane plant crop, and b) increase the stalk yield in the second harvest (first ratoon) by up (1)

“…However, its use can also harm the soil-plant system, due principally to an imbalance in nutrients in this waste (Bertoncini et al, 2004). Furthermore, SS can provide significant amounts of potentially toxic elements, such as heavy metals (Walter et al, 2006;Singh and Agrawal, 2008;Méndez et al, 2012), pharmaceuticals (Redshaw et al, 2008), hormones (Stumpe and Marschner, 2007), aromatic hydrocarbons (Cai et al, 2007), as well as pathogens such as helminth eggs, fecal coliforms, salmonella, protozoan cysts and viruses (Gaspard et al, 1997;Gerba and Smith, 2005).…”

ABSTRACT:Sewage sludge (SS) has been widely used as organic fertilizer. However, its continuous use can cause imbalances in soil fertility as well as soil-water-plant system contamination.The study aimed to evaluate possible improvements in the chemical and microbiological characteristics of domestic SS, with low heavy metal contents and pathogens, through the composting process. Two composting piles were set up, based on an initial C/N ratio of 30:1, with successive layers of tree pruning waste and SS. The aeration of piles was performed by mechanical turnover when the temperature rose above 65 ºC. The piles were irrigated when the water content was less than 50 %. Composting was conducted for 120 days. Temperature, moisture content, pH, electrical conductivity (EC), carbon and nitrogen contents, and fecal coliforms were monitored during the composting. A reduction of 58 % in the EC of the compost (SSC) compared with SS was observed and the pH reduced from 7.8 to 6.6. There was an increase in the value of cation exchange capacity/carbon content (CEC/C) and carbon content. .In SSC, helminth eggs were eliminated, making application sustainable for agriculture purposes.

“…With this in mind, it is important that data from tropical soils is obtained but, first, the extent of existing knowledge and data in this context must be gauged. Many authors have commented on the relative lack of data andyor information on the subject of trace metal behaviour in tropical soils and on the scarcity of studies in this area (Davies, 1997;Kookana and Naidu, 1998;Naidu et al, 1998;Onyatta and Huang, 1999;Mbila et al, 2001;Appel and Ma, 2002;Herpin et al, 2002;Campos et al, 2003;Reeves, 2003;Bertoncini et al, 2004;de Alcantara and de Carmargo, 2004;Udom et al, 2004). A logical first step, and the aim of this paper, is to collate current knowledge and to seek a better understanding about the behaviour of trace metals in tropical soils.…”

The mobility and bioavailability of trace metals in tropical soils: a review

In recent years, initiatives on critical loads of metals have resulted in the development of models to predict critical, i.e. mobile or bioavailable, concentrations of potentially toxic elements in soils. These models have been based on data from temperate soils and, considering the fundamentally different soil chemistry of the major tropical soil types, it is unlikely that such models could be applied successfully in the tropics. In particular, the major tropical soil types, particularly oxisols and ultisols, are distinguished from most temperate soils by low activity clays, low organic matter contents, low pH values and high levels of Fe oxides. The aim of this review paper is to collate existing information on the behaviour of trace metals in tropical soils, particularly in relation to metal mobility and bioavailability, and note differences, where these exist, with temperate soils. The main findings are as follows. The acidic nature of many tropical soils may not, of itself, lead to greater metal solubility. The relatively low organic matter content of tropical soils suggests that it cannot be relied upon to retain metals. However, when it is present, it appears to be important in the retention of copper, lead and zinc. The clay fractions of many tropical soils are dominated by kaolinite which is less able than 2 : 1 layer silicate clays to adsorb metals. However, oxisols and ultisols in particular have relatively high Fe oxides contents and these may be effective in metal sorption. Overall though, soils such as oxisols and ultisols appear to sorb relatively low amounts of added metals, most likely explained by the low activity clay minerals they contain and the rapid decomposition of organic matter incorporated into them. Dominant retention mechanisms, where they occur, are inner and outer sphere adsorption but not precipitation. Cadmium, Cu, Zn and Ni appear to be mobile in tropical soils. Chromium may be mobile in the A horizon but retained in the B horizon. The evidence for Pb points to surface retention, as is often observed for this metal in temperate soils. Metals in contaminated tropical soils appear to be rather bioavailable, judging by the few studies on plant uptake. It should be noted that the above statements are based on a relatively small number of studies. Further work is required if we are to gain an improved understanding of the mobility and bioavailability of trace metals in tropical soils.
