Effluents from different industrial supply conglomerates are often discarded in the environment without proper treatment. The concern for an economically viable industrial production line, which is both environmentally sound and socially acceptable, is increasing. Some of these effluents are alkaline in nature and may be used as an alternative to chemical conditioners for acidic soils in agricultural systems. This research aimed to evaluate changes in the chemical attributes of a Dystroferric Red Latosol (Oxisol) after application of an effluent from a pharmaceutical industry. The experiment was conducted in a greenhouse using PVC tubes of 1-m length and a 0.2-m diameter filled with soil and different doses of the effluent. After 3 days, 100 mm of water was applied to each treatment. The PVC tubes were incubated for 30 days; thereafter, the tubes disassembled, and soil chemical analysis were ResumoOs efluentes das diversas cadeias produtivas industriais são muitas vezes descartados no ambiente sem tratamento adequado. A preocupação por uma linha de produção industrial economicamente viável, ambientalmente correta e socialmente aceita é cada vez mais preconizada. Alguns desses efluentes apresentam caráter alcalino, e podem ser utilizados como condicionadores químicos de solos ácidos, em sistemas agrícolas. Objetivou-se com a realização do presente trabalho, avaliar alterações químicas de um LATOSSOLO VERMELHO distroférrico, após aplicação de efluente da indústria farmacêutica. O experimento foi realizado em casa de vegetação e conduzido em tubos de PVC de 1 m de comprimento e 0,2 m de diâmetro. Nos tubos, preenchidos com solo, foram aplicadas diferentes doses do efluente. Após 3 dias, 100 mm de água foi aplicado sobre cada tratamento. As colunas foram incubadas por 30 dias, posteriormente desmontadas e feitas análises químicas nas diferentes profundidades: 0-0,2; 0, 2-0,4; 0,4-0,6; 0,6-0,8 e 0,8-1,0

“…The use of urban waste compost in agriculture allows the cycling of organic matter and nutrients (Melo et al, 2011), and thus helps to maintain or restore soil chemical, physical and biological properties (Kray et al, 2011;Krob et al, 2011). In this sense, several studies have addressed the changes in soil chemical properties and plant nutrition induced by the application of urban waste compost (Sampaio et al, 2010;Krob et al, 2011;Lima et al, 2011).…”

SUMMARYThe use of urban waste compost as nutrient source in agriculture has been a subject of investigation in Brazil and elsewhere, although the effects on soil physical and chemical properties and processes are still poorly known. The aim of this study was to evaluate the effect of application of urban waste compost and mineral fertilizer on soil aggregate stability and organic carbon and total nitrogen content of a Rhodic Hapludox under no-tillage in the northwestern region of Rio Grande do Sul, Brazil, in the 2009/2010 and 2010/2011 growing seasons. The experiment was arranged in a 2 × 6 (seasons and fertilization) factorial in a randomized complete block design with four replications. The factor time consisted of two growing seasons (sunflower in 2009/10 and maize in 2010/11) and the factor fertilization of five rates of urban waste compost (0, 25, 50, 75 and 100 m 3 ha -1 ), and mineral fertilizer. Soil samples were collected from the 0.0-0.10 m layer to determine aggregate stability (mean weight and geometric diameter), soil organic carbon (SOC) and total nitrogen (TN). Rates of up to 75 m 3 ha -1 of urban waste compost, after two years of application to no-tillage maize and sunflower, improved aggregation compared to mineral fertilization in a Rhodic Hapludox. After the second crop, the SOC and TN contents increased linearly with the levels of urban waste compost.Index terms: soil organic carbon, aggregate stability, total nitrogen, soil structure, organic manure.( A utilização de composto de lixo urbano como fonte de nutrientes para a agricultura vem sendo investigada; entretanto, as alterações físicas do solo ainda são pouco conhecidas. Objetivouse avaliar a influência do uso de composto de lixo urbano e da adubação mineral na estabilidade de agregados e nos teores de carbono orgânico e nitrogênio total de um Latossolo Vermelho, em sistema plantio direto na região noroeste do Rio Grande do Sul. Utilizou-se o delineamento de blocos ao acaso, em esquema fatorial 6 × 2 (adubação e épocas), com quatro repetições. O fator épocas de avaliação constituiu-se dos anos agrícolas de 2009/10 (girassol) e 2010/11 (milho). O fator adubação foi composto por cinco doses de composto de lixo urbano (0, 25, 50, 75 e 100 m 3 ha -1 ), além de um tratamento adicional com fertilização mineral. Na camada de 0,0-0,10 m, foram determinados a estabilidade de agregados (diâmetro médio geométrico e ponderado), os teores de carbono orgânico (CO) e o nitrogênio total (NT). A utilização de doses crescentes de composto de lixo urbano favoreceu melhorias na agregação do solo, em relação à fertilização mineral. A utilização de até 75 m 3 ha -1 de composto de lixo urbano, após dois anos de aplicações em cultivos agrícolas com milho e girassol em um Latossolo Vermelho, sob sistema plantio direto, promoveu melhorias na agregação do solo, quando comparada à fertilização mineral. O teor de CO e o de NT, após o segundo cultivo, apresentaram incrementos lineares, em relação às doses de composto de lixo urbano.Termos de indexação: carbono orgâ...

“…Increases in the values of OM and V of the soil with the addition of organic fertilizers are reported in the literature (Strojaki et al, 2013). The increment of OM promotes improvements of soil chemical and physical attributes, resulting in greater availability of nutrients, permeability and water movement in the soil (Krob et al, 2011;Sampaio et al, 2012), besides providing organic acids that are important for the solubility of the minerals and increment in the recycling and mobility of nutrients (Pavinato & Rosolem, 2008).…”

The fertilization with biofertilizer associated with the use of irrigation favors nutrient uptake by plants and soil chemical properties; however, these effects are little studied in Tithonia diversifolia in semiarid regions. This study evaluated the effect of doses of bovine biofertilizer and irrigation on accumulation of nutrients in the leaves of Tithonia diversifolia plants and on soil chemical attributes. The study was carried out from December 3, 2014 to November 28, 2015, and arranged in a 2 x 5 factorial scheme, consisting of five doses of bovine biofertilizer (0, 40, 80, 120 and 160 m3 ha-1), combined with and without irrigation. The experiment was set in a randomized block design, using three replicates. Irrigation promoted increased accumulation of N, P, K, Ca, Mg, S, Zn, Fe, Mn, Cu and B in leaves of Tithonia diversifolia in the first cutting. However, the high bicarbonate concentration in the irrigation water and the occurrence of rainfall during the second crop increased the accumulation of Cu in the leaves of Tithonia diversifolia under rainfed condition, compared with irrigated plants. The increase in biofertilizer doses contributed to the increment of base saturation and the contents of organic matter, P and K in soil.
