“…Sendo considerada uma suspensão de sólidos orgânicos e minerais, a vinhaça, contendo os componentes do vinho, vinhoto ou restilo, não arrastados na fase de destilação, além de quantidades residuais de açúcar e álcool. É uma suspensão com teor de sólidos, com cerca de 7%, desses 75% orgânicos e biodegradáveis, apresentando elevadas DQO e DBO, por conta desse fator seu alto potencial poluidor, somando-se a isso, apresentando solução tamponada com pH em torno de 4,3, quando obtida em altas temperaturas, fato que lhe atribui característica corrosiva (Cabral Filho et. al., 2019).…”

A adoção de práticas que minimize os impactos ambientais e melhoria da fertilidade do solo para exploração agrícola tem sido realizada com maior frequência. O presente trabalho teve como objetivo avaliar a qualidade do solo em áreas com diferentes doses de vinhaça e torta de filtro sobre os atributos químicos do solo. O experimento foi realizado na Estação Experimental do IPA, Vitória de Santo Antão - PE, constituído de dois tratamentos e cinco níveis de aplicação de doses de vinhaça 0;19,42; 77,68; 155,36 e 310,72 m3 ha-1) e cinco doses de torta de filtro (0; 2,75; 11,0; 22,0 e 44,0 t ha-1), em blocos casualizados com quatro repetições. Os dados obtidos foram submetidos à análise de variância e de regressão, utilizando o software SAS, com níveis de significância de 5% para o teste F. Com relação aos atributos químicos do solo tratados com torta de filtro foram verificados efeitos lineares significativos (p<0,05) para os teores de fósforo, cálcio e capacidade de troca de cátions (CTC) no solo. Relacionado a vinhaça foi verificado efeito quadrático significativo (p<0,05) proporcionando redução no teor de fósforo no solo, posteriormente, ocorrendo incremento de 8,88% com a dose máxima aplicada. Os resíduos aplicados torta de filtro e vinhaça promoveram melhoria nas propriedades químicas do solo potencializando seu uso na agricultura.

The data obtained were submitted to analysis of variance and regression, using the SAS software, with significance levels of 5% for the F test. Regarding the chemical attributes of the soil treated with filter cake, significant linear effects were verified (p < 0.05) for phosphorus, calcium and cation exchange capacity (CTC) in the soil. Related to vinasse, a significant quadratic effect (p <0.05) was observed, providing a reduction in the phosphorus content in the soil, subsequently, with an increase of 8.88% with the maximum applied dose. The residues applied filter cake and vinasse promoted an improvement in the chemical properties of the soil, enhancing its use in agriculture.Keywords: filter cake, vinasse, soil attributes, conditioners, fertility.

“…However, there are many studies that show the importance of N in the sugarcane crop (Wiedenfeld andEnciso, 2008, Silva et al, 2009;Franco et al, 2011). To Cabral Filho et al (2018) the appropriate application of agricultural inputs, contributes to the preservation of the environment, besides optimizing the enterprise's profitability, as it allows greater productivity and minimizes waste.…”

Sugarcane is the most promising crop among renewable biofuels producers and one of the countries that produces the most green matter per unit area, whose greater limitations to productivity are mainly related to the adequate availability of water and mineral nutrients, in particular nitrogen (N). Based on the hypothesis that the source and the availability of nitrogen influence the growth, development and yield of irrigated sugarcane in the cerrado region. The objective of this study was evaluate the biometric variables and yield of irrigated sugarcane, in the cane-plant cycle, as affected by source and nitrogen rate. The soil utilized was an Oxisol (Rhodic Hapludox), cerrado (savannah) phase. The experiment was carried out at Farm of the Raízen Mill, located in the municipality of Jataí, Goias State, Brazil. The variety IACSP95-5000 was used in a randomized block design, analyzed in a split-split-plot scheme, with three replicates. The treatments were four N rates (0, 60, 120 and 180 kg ha-1); two fertilizer sources (urea and ammonium nitrate). The factors evaluated were in the plots of four doses of N (0, 60, 120 and 180 kg ha-1). In the subplot two sources of N (urea and ammonium nitrate) and as sub-subplot were represented by four evaluation periods (210, 250, 290 and 330 days after the planting-DAP). The irrigation was by sprinkling, in a central pivot. The evaluated variables were: plant height, stalk diameter, total number of leaf, leaf area, number of industrializable tillers, stalk yield, pointer yield and total recoverable sugars. The highest stalk yield, pointer yield and total recoverable sugars occurred at the average dose of 143.61 kg ha-1 of N, with an average increase of 25.87%.

“…According to Seixas (2006), the acidity of the effluent is mainly due to the presence of sulfuric acid that is added to the must during the fermentation stage, in addition to the presence of organic matter that is basically in the form of organic acids. Even though vinasse is an acid residue, it is capable of increasing the pH of soils, due to the reduction reactions (which consume H + ) that occur after the application of vinasse; in addition to the neutralization of H + , Al 3+ and Fe 3+ in the soil the negative charges of functional groups of organic matter provided by vinasse (Rosado et al, 2007;Cabral Filho et al, 2019).…”

The objective of this study was to evaluate efficient analytical methods of wet digestion using the official method of analysis, a mixture of nitric acid and perchloric acid (HNO3 + HClO4), for the analysis of vinasse and also verify the effects of nutrients on stored vinasse. The analytical methods compared were: 1) Nitroperchloric (HNO3), 2) Nitric (HNO3); 3) Chloridric + Hydrogen Peroxide (HCl + H2O2); 4) Sulfuric + Hydrogen Peroxide (H2SO4 + H2O2) and 5) Solubilization with 1 molar Chloridric acid (HCl 1 Mol L-1). Phosphorus, potassium, calcium, magnesium and sulfur were determined over different storage periods, and these nutrients were analyzed at 5, 30, 90 and 150 days of storage, to verify the behavior of these nutrients over the time they are stored in laboratory conditions. The efficiency of the methods was evaluated by comparing the results of the nitroperchloric method obtained for each nutrient with the results obtained from the other methods. The results showed that the nitric (HNO3) and chloridric + hydrogen peroxide (HCl + H2O2) digestions presented good to excellent precision equivalent to the nitroperchloric digestion (HNO3) for the analyzed nutrients. The solubilization method with 1 molar chloridric acid (HCl 1 Mol L-1) presented a low accuracy and did not present the expected efficiency for quantification of any analyzed nutrient. With the exception of potassium contents, all the other nutrients analyzed in the study reduced at the end of the vinasse storage days.
