“…The contents of macronutrients in sunflower leaves were not influenced by the residual effect of sewage sludge applied in the first cycle; Mg and S remained below the nutrient sufficiency range in the plant (Table 6) (Albuquerque et al, 2015). According to Zuba Junio et al (2012), the residual effects of sewage sludge fertilization influence the leaf contents of N, P and K, after one year of its application in the soil and two consecutive maize cycles.…”

This study aimed to evaluate the residual effect of sewage sludge fertilization on yield and nutrition of sunflower in its second cycle. The experiment was carried out from April to August 2012. The treatments consisted of four doses of sewage sludge (0, 10, 20 and 30 t ha-1, dry basis) applied in the first cycle of sunflower, distributed in a randomized block design, with six replicates. Sunflower stem diameter, plant height, capitulum diameter and yield increased with the increment in sewage sludge doses, with maximum values observed with the dose of 30 t ha-1. The contents of calcium and magnesium in the soil, pH, sum of bases, effective and potential cation exchange capacity and base saturation increased, while potential acidity and the contents of manganese and iron in the leaves decreased, with the increment in the residual doses of sewage sludge. There was a reduction in yield and growth characteristics of sunflower in the second cycle; thus, additional fertilization with sewage sludge is recommended in each new cycle.

“…The zinc contents (Zn 2+ ) showed an increase with high correlation on the SS fertilizations at the 0 to10 cm depth (p<0.05) (Table 3 and Figure 1). The increments on the Zn 2+ contents on the soil with the use of SS have been observed on several researches on tropical soils (Zuba Junio et al, 2012;Nascimento et al, 2014;Cavalcanti et al, 2015) and, depending on the chemical characteristic of this organic fertilizer, the supply of the micronutrient may reach levels higher than 4 kg ha -1 (Albuquerque et al, 2015).…”

“…The productivity results obtained are considered close to the Brazilian means on single production systems with soy beans on the 2014-2015 crop, estimated at 3.016 kg ha -1 , according to the National Supply Company (Conab, 2015). The use of SS has also shown an increase on the productivity of sunflower seeds (Albuquerque et al, (2015), in addition to similar productivities when mineral fertilizers are used on cultures for the production of castor beans (Cavalcanti et al, (2015).…”

“…One highlight is cattle manure, since it offers benefits to the chemical attributes of the soil, helping to increase mineralization and the availability of nutrients to the plants (Tejada et al, 2008), mainly due to its capacity to interact with metals and metal oxides and hydroxides, creating organometallic compounds, in addition to potentiate the nitrogen and phosphor stocks (Muraishi et al, 2011) Another byproduct, from an urban origin, sewage sludge has been deeply investigated regarding the potential improvements of the chemical attributes of the soil (Ricci et al, 2010;Bittencourt et al, 2012;Costa et al, 2014;Cavalcanti et al, 2015). However, concerns have emerged since it leads to a significant concentration of heavy metals on the soil (Nascimento et al, 2014;Albuquerque et al, 2015). Considering these questions, the search for solutions for an adequate destination for this byproduct has been considered vital, and agricultural recycling seems like the most promising alternative from the economic and environmental perspective (Barbosa et al, 2007).…”

The reuse of organic byproducts in agroforestry systems is a sustainable proposal, since, in addition to preserving the natural resources, it has allowed the fertilization of the soils, obtaining a reduction of costs with mineral fertilizers. Therefore, the objective of this research was to evaluate the chemical attributes of the soil after two years of successive fertilizations using cattle manure and sewage sludge in agroforestry systems. The study was conducted in Goiânia, state of Goiás, Brazil. The experimental design used randomized blocks on a 2 x 4 factorial (cultivation systems and fertilizations), with four repetitions. The cultivation systems were: agroforestry and monoculture systems. The fertilizations used were: cattle manure, sewage sludge, mineral fertilizer and control (no fertilization). Regardless of the cultivation system, the fertilizations with sewage sludge increases the calcium, phosphor and zinc contents of the soil, as well as the pH values, sum of bases and cation exchange capacity, at 0-10cm depth. However, the potassium contents are lower in relation to the use of mineral fertilizers, both at 0 to 10 cm depth and at 0 to 20 cm. Teak plants in agroforestry systems presents similar heights to the monoculture plants, and they are higher on fertilizations with sewage sludge. The soybean grain productivity in the agroforestry system presents similar outputs in relation to the use of sewage sludge and mineral fertilizers. Therefore, it is recommended for farmers to adopt agroforestry systems and the organic fertilization practice with sewage sludge, associating the quality of the chemical attributes of the soil, the growth of forest species and soybean grain yields.

“…Many studies have demonstrated increases in the production of dry matter and/or grains by species of agronomic interest cultivated in soils treated with sewage sludge (Lobo et al, 2012;Albuquerque et al, 2015;Freitas et al, 2015); however, the polluting effect of sewage sludge is related to the levels of microorganisms and heavy metals that it may contain. The presence of microorganisms is undesirable, because of the risks to human and animal health (Backes et al, 2009;Fialho et al, 2010).…”

A B S T R A C TOne of the main urban polluting agents are the sewers, which even with proper treatment end up generating a polluting waste, the sewage sludge. One of the options for the disposal of this sludge is the use in agriculture, due to its high content of organic matter and nutrients. This study aimed to use urban sewage sludge for lemongrass cultivation and essential oil production. The plants were grown in soil containing different organic compost doses (0, 5, 10, 20, 40 and 60 t ha -1 ), formed from the sewage sludge composting process and waste of urban vegetation pruning. At harvest, plants were analyzed for the concentration of nutrients, chlorophyll content, number of tillers, biomass production, essential oil content and the microbiological quality of the leaves. The results showed that the addition of the compost increased the levels of nutrients in the plants, mainly nitrogen, positively influencing the production of tillers, biomass, chlorophyll contents, yield and essential oil content.Produção de óleo essencial de capim-limão (Cymbopogon citratus) sob composto orgânico contendo lodo de esgoto R E S U M O Um dos principais agentes poluidores urbanos são os esgotos que, mesmo com o devido tratamento, acabam por gerar um resíduo poluente, o lodo de esgoto. Uma das opções para destinação deste lodo é sua utilização na agricultura em virtude do alto teor de matéria orgânica e nutrientes. Objetivou-se, com este trabalho, o aproveitamento de lodo de esgoto urbano para o cultivo de capim-limão, além da produção de óleo essencial. As plantas foram cultivadas em solo contendo doses de composto orgânico (0, 5, 10, 20, 40 e 60 t ha -1 ), formado a partir do processo de compostagem de lodo de esgoto e resíduos de poda de vegetação urbana. Na colheita foram analisadas as concentrações de nutrientes nas plantas, os teores de clorofila, número de perfilhos, produção de biomassa, óleo essencial e a qualidade microbiológica das folhas. Os resultados demonstraram que a adição do composto aumentou os teores de nutrientes nas plantas sobretudo o nitrogênio, influenciando positivamente na produção de perfilhos, biomassa, teores de clorofila, rendimento e teor do óleo essencial.
