“…Esta situação representa risco ambiental, pois o aumento gradual da capacidade do solo em fornecer N (Jin et al, 2011) deve, teoricamente, ser acompanhado da redução nas doses aplicadas, para prevenir o excesso de N inorgânico, a lixiviação de NO 3 -para águas subterrâneas (Medaile et al, 1994;Oliveira et al, 2001;Dynia et al, 2006) e a emissão de N 2 O para a atmosfera (Chiaradia et al, 2009;Pitombo, 2011).…”

Resumo -O objetivo deste trabalho foi avaliar a dinâmica de mineralização do C e a capacidade do solo em fornecer N após sucessivas aplicações de lodo de esgoto, além de determinar a relação destas com a taxa de mineralização do lodo previamente aplicado. A área experimental recebeu, por sete anos, os seguintes tratamentos: 80 kg ha -1 por ano de N mineral (L0); e 10 ou 20 Mg ha -1 por ano de lodo (L1 e L2, respectivamente). Amostras de solo (0-20 cm) foram retiradas um ano após a última aplicação dos tratamentos. As amostras receberam doses de lodo correspondentes a 0, 120 e 240 kg ha -1 de N e foram incubadas em laboratório por mais de 100 dias, tendo-se determinado o C-CO 2 liberado e o teor de N inorgânico no solo. A mineralização do C e do N foi mais influenciada pelo uso prévio do lodo do que pelas doses incubadas. A taxa de mineralização do nitrogênio (TMN) diminuiu de 16%, em L0, para 11%, em L1, e 8% em L2. No entanto, essa redução não resultou em menor disponibilidade de N no sistema, pois houve incremento do N potencialmente mineralizável (N 0 ) em L1 e L2. Assim, a TMN não é um parâmetro adequado para cálculo da dose de lodo a ser aplicada em áreas previamente tratadas com o resíduo, pois subestima a capacidade do sistema em fornecer N. Neste caso, deve-se considerar o uso do N 0 .Termos para indexação: fertilizante nitrogenado, matéria orgânica, nitrogênio potencialmente mineralizável, resíduo, taxa de mineralização do nitrogênio. Mineralization of carbon and nitrogen in soil after successive applications of sewage sludgeAbstract -The objective of this work was to evaluate the dynamics of carbon mineralization and the soil capacity in providing nitrogen after successive applications of sewage sludge, as well as to determine their relation with the mineralization rate of the sludge previously applied. The experimental area received for seven years the following treatments: 80 kg ha -1 per year of mineral N (L0); and 10 or 20 Mg ha -1 per year of sewage sludge (L1 and L2, respectively). Soil samples (0-20 cm) were taken one year after the last application of the treatments. Samples received sewage sludge doses corresponding to 0, 120, and 240 kg ha -1 of N and were incubated in laboratory for more than 100 days, with determination of C-CO 2 emission and inorganic soil N content. The mineralization of C and N was more influenced by the previous use of sludge than by the incubated doses. The nitrogen mineralization rate (NMR) reduced from 16%, on L0, to 11% on L1 and 8% on L2. However, this reduction did not result in lower N availability on the system, since there was an increase of the potentially mineralizable nitrogen (N 0 ) in L1 and L2. Therefore, the NMR is not an adequate parameter for calculating the sewage sludge dose to be applied on areas previously treated with the residue, since it underestimates the system capacity of providing N. In this case, the use of N 0 should be considered.

“…Then, applications of sewage sludge were in 15 May, 2009, 16 April, 2010, 14 April, 2011, and 28 April, 2012 The sewage sludge was distributed on the whole soil surface of each column, and incorporated at the first 10 cm deep, avoiding the soil revolving for the deepest layers. Considering the content of N found in the sludge and 28% of mineralization rate -in kg ha -1 -in the first year after application (Chiaradia et al, 2009) The ammonium sulphate was added to each lysimeter during the first application of sewage sludge and about four months after, at doses about 188 and 97 kg ha -1 . The potassium chloride was also added to each lysimeter during the first application, according to doses of sewage sludge as follows: 177, 132, 87 and 0 kg ha -1 for doses 0, 11, 22 and 44 Mg ha -1 .…”

Brazil seeks to optimize the use of fertilizers by taking advantage of agricultural residues. The sewage sludge is used as organic matter in various crops such as coffee. However, an experiment in lysimeter was performed seeking to assess the growth, yield and content of zinc, copper, nickel, cadmium, lead and chromium in coffee fruits grown on Dystrophic Red Yellow Latosol (dRYL), Dystropherric Red Latosol (dRL) and Dystrophic Red Yellow Argisoil (dRYA); under successive application of sewage sludge. The sewage sludge increased the content of Cd, Cr, Cu, Pb and Zn found in soils under study. The sewage sludge decreased coffee growth and productivity and increased the content of Cu, Zn and Cd found in coffee peel. Greater content of Cd in coffee seeds for all three soils, as well as greater content of Zn and Pb in coffee seeds grown on Dystropherric Red Latosol was also found.

“…A few studies have reported the effects of SS fertilization on the levels of heavy metals in the soil and castor bean plant, but only related to the applied doses of the sludge (CHIARADIA et al, 2009;CAVALCANTI et al, 2015;NASCIMENTO et al, 2015). However, it is also important to study the processes of SS stabilization and their respective effects on the levels of heavy metals in the soil and castor bean plant.…”

This study evaluated the levels of heavy metals in the soil and castor bean plant after fertilization with sewage sludge (SS) subjected to different stabilization processes. The study was conducted in a Haplic Cambisol with the following treatments: control (CO), fertilization with solarized sewage sludge (SSS), composted sewage sludge (CSS), vermi composted sewage sludge (VSS), limed sewage sludge (LSS), and mineral fertilizer (MF). The experimental design included a subdivided plot scheme with fertilization being the primary factor and soil layers or leaf parts being the secondary factor. The data obtained were analyzed using analysis of variance and the Scott-Knott test with 5% significance. Fertilization with SSS, CSS, and LSS led to the highest increase in Zn in the soil, mainly in the surface layer. In the leaf tissues, Zn and Cu levels were higher with the CO and SSS treatments, whereas the Ni level was higher with SSS, CSS, VSS, and MF treatments. In general, Zn and Cu levels were higher in the leaf limb than in the petiole, whereas Ni, Pb, and Cr levels were higher in the petiole than in the leaf limb. In any case, no symptoms of toxicity in the plants and no risk of soil contamination were observed with any of the fertilization treatments.
