“…Also, soil organic matter content, which were equal to 3.39 and 2.00 dag kg -1 in the layers of 0-0.20 and 0.20-0.40 m before the experiment, and classified as medium and low, increased to 3.62 and 2.10 dag kg -1 , respectively, resulting in the change of classification for the layer of 0.20-0.40 m from low to medium, according to Alvarez V. et al (1999). Chiba et al (2008), studying sugarcane, also verified increase in soil organic matter content with the application of sewage sludge.…”

The aim of this study was to evaluate the effect of thermally dried sewage sludge on soil fertility, growth and yield of sunflower. The experiment was conducted in a Nitosol area of the Institute of Agricultural Sciences of the Federal University of Minas Gerais, in Montes Claros-MG, Brazil. The treatments consisted of four doses of sewage sludge (0, 10, 20 or 30 t ha-1, dry weight basis), with six replicates in a randomized block design. The levels of nutrients in soil and plant, soil fertility indices, stem diameter, plant height, head diameter and grain yield were evaluated. Stem diameter, plant height, head diameter and grain yield increased with increasing doses of sewage sludge. The application of the residue increased linearly the contents of soil organic matter and N in sunflower leaves. On the other hand, pH, the exchangeable bases, total and effective cation exchange capacity, base saturation, H+Al, Al, soil contents of P, K, Ca, Mg, S, Zn, Cu, Mn, Fe and B, and the leaf contents of P, K, Ca, Mg, S, Zn, Cu, Mn, Fe and B were not influenced by the application of sewage sludge doses of up to 30 t ha-1.

“…The SS application increased the foliar nitrogen concentration in the eucalyptus (Eucalyptus grandis), when compared to the mineral fertilizer (Guedes & Poggiani, 2003). Other authors also concluded that its application can increase the absorption of elements, which are normally present in lower concentrations in the sludge, such as the phosphorus (Chiba et al, 2008). …”

One option for the increasing production of sewage sludge (SS) is its agricultural use in crops with high nutritional demand, such as the rose. Therefore, the aim of this work was to study the application of SS from primary stabilization pond in roses of the variety 'Carola'. For the experiment, the roses were planted in 20 L recipients using increasing doses of sludge (T2 -12 Mg ha ), mineral fertilizer (T5) and control treatment (T1, without N) in a randomized block design. The evaluated parameters were: roots dry mass, aerial dry mass, total biomass, leaflets area and nitrogen concentration in the leaf. The SS application resulted in better development of the rose, increasing the roots and the aerial biomasses, the leaflets area, and nitrogen content in the leaves compared to the control (T1). There was no statistical difference between the use of mineral fertilizer (T5), and the SS under the highest dose (T4). With these benefits, the use in agriculture of sewage sludge derived from stabilization ponds proved to be an adequate option for its disposal.Uso de lodo de lagoa de estabilização no cultivo de roseira R E S U M O Uma opção para a crescente geração de lodo de esgoto (LE) é seu uso na agricultura em cultura com alta demanda de nutrientes, como a roseira. Portanto, o objetivo deste trabalho foi estudar a aplicação do lodo de lagoa facultativa primária em roseiras da variedade 'Carola'. Para a realização do experimento as roseiras foram plantadas em baldes de 20 L utilizando-se doses crescentes de lodo (T2 -12 Mg ha ), adubo mineral (T5) e testemunha absoluta (T1) com delineamento em blocos casualizados. Os parâmetros avaliados foram: massa seca das raízes, massa seca da parte aérea, biomassa total, área dos folíolos e concentração de nitrogênio no tecido foliar. A aplicação de LE resultou em melhor desenvolvimento da roseira aumentando a biomassa das raízes, da parte aérea, área dos folíolos e o teor de nitrogênio nas folhas quando comparado com o tratamento controle (T1). Também foi constatado que não houve diferença estatística entre o uso de adubo mineral (T5) e LE na maior dose (T4). Com esses benefícios o uso de lodo de lagoa facultativa em roseira mostrou ser uma opção adequada para o destino deste resíduo.

“…In Brazil, numerous studies have shown benefits from using SS in farming areas either for recovery of degraded areas or as partial or total fertilization of soils under forestry (ANDRADE et al, 2005;PELISSARI et al, 2009), fruit plantation (COELHO, et al, 2011) or crops as cotton, wheat, sugarcane, soybean, black oat, sunflower, among others (FIGUEIRÊDO et al, 2005;CHUEIRI et al, 2007;CHIBA et al, 2008;BEHLING et al;;LOBO et al, 2012a;LOBO et al, 2013).…”

Several research lines are required to ensure a proper disposal of sewage sludge in Brazil; among them, we may highlight agricultural use. In this sense, this study aimed at assessing the effect of exchanging nitrogen sourcing via conventional fertilization (chemical) with growing doses of composted sewage sludge (CSS) on wheat crop performance. The experiment was performed in a completely randomized design with seven treatments and ten replications, being defined as T0 (control -without fertilization); T1 (100% mineral fertilization); T2 (50% mineral + 50% CSS); T3, T4, T5, and T6 (100, 150, 200, and 250% nitrogen fertilizing from CSS). Results showed that the use of CSS increased wheat production and development, therefore enhancing its performance. Thus, exchanging mineral fertilization with CSS application raised wheat yields.
