“…a similar result was obtained with maize plants treated with up to 500 m 3 ha -1 Bs from gelatin industry (taniguchi, 2010). an increase in soil mineral-N in areas of application of other wastes was frequently reported (smith et al, 1998;Vieira & Cardoso, 2003;Boeira & maximiliano, 2009Boeira & maximiliano, ). taniguchi (2010 found that mineral-N increased in an ultisol (sandy clay loam) proportionally to the application of Bs from gelatin industry.…”

summary the impact of agro-industrial organic wastes in the environment can be reduced when used in agriculture. from the standpoint of soil fertility, residue applications can increase the organic matter content and provide nutrients for plants. this study evaluated the effect of biological sludge from gelatin industry on the chemical properties of two ultisols (loamy sand and sandy clay) and an oxisol (clay). the experiment lasted 120 days and was carried out in laboratory in a completely randomized design with factorial arrangement, combining the three soils and six biological sludge rates (0, 100, 200, 300, 400, and 500 m 3 ha -1 ), with three replications. Biological sludge rates of up to 500 m 3 ha -1 decreased soil acidity and increased the effective cation exchange capacity (CeC) and n, Ca, mg, and P availability, without exceeding the tolerance limit for na. the increase in exchangeable base content, greater than the effective CeC, indicates that the major part of cations added by the sludge remains in solution and can be lost by leaching. index terms: waste, nutrients, soil ph, effective CeC. resumo: ATRIBUTOS QUÍMICOS DE SOLOS TRATADOS COM LODO BIOLÓGICO DE INDÚSTRIA DE GELATINA O impacto dos resíduos orgânicos agroindustriais no ambiente pode ser reduzido com o seu uso agrícola.

“…According to Boeira and Maximiliano [18,19], the available N in sewage sludge-amended soils is one of the restrictive factors for residue application in great amounts. This criterion must be considered in regulations for agricultural use of sewage sludge to avoid nitrate enrichment because of its potential to pollute subsurface water bodies.…”

“…This quantity, combined with mineral N in the sludge, determines the amount of N in sewage sludge that will be available during the growing season [19]. The purpose of the Boeira and Maximiliano [18] study was to verify the potential availability of mineral N in a Latossol under corn previously treated with sewage sludge ( Table 2). The N mineralization potential estimated by the single exponential model was 28 mg kg −1 for soil without sludge and ranged from 28 to 100 mg kg −1 for soil treated with Franca sludge and from 40 to 113 mg kg −1 for soil treated with Barueri sludge after four sewage sludge applications [18].…”

A long-term assay was conducted to evaluate the environmental impacts of agriculture use of sewage sludge on a tropical soil. This paper describes and discusses the results obtained by applying a interdisciplinary approach and the valuable insights gained. Experimental site was located in Jaguariúna (SP, Brazil). Multiyear comparison was developed with the application of sewage sludge obtained from wastewater treatment plants at Barueri (domestic and industrial sewage) and Franca (domestic sewage), São Paulo State. The treatments were control, mineral fertilization, and sewage sludge applied based on the N concentration that provides the same amount of N as in the mineral fertilization recommended for corn crop, two, four, and eight times the N recommended dosage. The results obtained indicated that the amount of sewage sludge used in agricultural areas must be calculated based on the N crop needs, and annual application must be avoided to prevent overapplications.

“…Trabalhos que avaliam a mineralização do N de lodos de esgoto após aplicação no solo são comuns; porém, os que avaliam áreas sujeitas a sucessivas aplicações do resíduo e estimam a quantidade mineralizável de N para cálculo das doses são escassos (Felipó & Garau, 1987;Boyle & Paul, 1989;Boeira, 2005;Hseu & Huang, 2005;Boeira & Maximiliano, 2009;Andrade et al, 2010;Gil et al, 2011). A quantificação do efeito residual do lodo e o estabelecimento da relação entre o N potencialmente mineralizável no solo e a nova dose para aplicação são caminhos que podem aprimorar o sistema de recomendação de lodo no Brasil (Conselho Nacional de Meio Ambiente, 2006).…”

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.
