“…Despite the changes on K + content, it probably was not enough to increase the dispersion of the clay fraction. This affirmation corroborates Melo et al (2018), testing doses of sugarcane vinasse in a Cambisol from Brazil, who observed that the increment of K + up to almost 5% of the cation exchange capacity was not enough to increase the water-dispersible clay content.…”

Purpose Many studies evaluate the effect of successive applications of chicken manure on soil attributes. In Brazil, the commercialization of this waste is common, implying on its sporadic use instead of many applications at the same area. The short-term effects of a single application of chicken manure and the role of its composting on soil structural stability are not fully understood. This study investigated application of in natura (uncomposted) and composted chicken manure on the structural stability of a Rhodic Ferralsol after a short period following single application. Methods The experiment was performed in a Rhodic Ferralsol in Londrina, Paraná. Brazil. We applied in natura and composted chicken manure at doses of 4.5, 9.0, 13.5, and 18.0 Mg ha −1 plus a control without application. Soil samples were collected after 185 days at the 0.0-20.0 cm layer for laboratorial analysis. Results The composting of chicken manure did not affect soil structural stability. Chicken manure did not alter water-dispersible clay (x = 21.7%), but increased the mean weight diameter of water-stable aggregates (MWD = 5.43 + 0.068 × dose) through the agglomeration of aggregates with 0.5-4 mm into 8-19 mm. Conclusion Even after a short period of 185 days, the application of chicken manure increases the structural stability of Rhodic Ferralsols and its composting, in the way performed by many farmers, is not associated with the improvement of soil structural stability in short-term. However, other advantages arise from the composting of the manure and need to be considered prior its use.

“…Some authors [23,26,29] affirm that contamination of groundwater and nutrients leaching is not significant below 300 m 3 ha -1 yr -1 . However, it depends on the characteristics of the soil, like ion CTC (Exchange Capacity), infiltration rate, storing capacity of nutrients, besides distance from water bodies [30].…”

“…Several authors have investigated technologies for vinasse treatment only based on technical and economic aspects without considering the environmental aspects quantified in the cash flow of the project. Many authors [30,48,49] address the environmental aspects of the best technological option but in a qualitative only way and considering only economic aspects for its analysis. This work needs additional studies of economic feasibility of these treatments considering the environmental aspects and others scenarios.…”

Vinasse improper disposal can cause damages to the environment. Fertigation, concentration and digestion aerobic or anaerobic generating fuel gas are the main technologies for vinasse use. Such alternatives present different impact on the environment; however, the weight of environment aspect in the decision remains under discussion. In this paper, authors present a discussion and valuations of environmental aspects about the main technologies of vinasse treatments. First, authors elaborated questionnaires, consulting specialists about the environmental and economical aspect of decision for changing to more environmentally friend technologies. The answers strongly suggest that the decisions of companies are mainly motivates by economics issue, and changing the current technology would be possible only if IRR (Internal Rate of Return) remains around 25%-30%. Then, authors proposed and performed calculations for inserting environmental aspects in the economical evaluation of technologies. The environmental resources performed considering carbon credit, economy with mineral fertilizers and the cost avoided with environmental fines. Scenarios and sensitivity cases performed, presenting discussions about the weight of environmental aspect in technology choice. It is possible to propose government policies that can economically value environmental benefits, such as tax reductions for people using vehicles to RGN (Renewable Gas Natural) or the implementation of a green label for companies that use biogas or RGN in their production processes (green label can be a differential or an extra score for company in future public bids, for example). The results showed that environmental aspect impacts directly the NPV (Net Present Value) of each technology, which can lead even to positive financial returns to companies; however, depending on valuation of environmental resources. Considering the environmental feature in economic impacts, the best option is the use of anaerobic digestion to produce energy that reduces carbon dioxide emissions or anaerobic digestion to produce gas if considering environmental scenario with the government policy of exemption from the tax on the ownership of motor vehicles. From the point of view of the land and water, it is possible to value economically in qualitative aspects through sectoral governmental policies.

“…Observando os efeitos principais da vinhaça sobre os atributos químicos do solo, Melo et al (2018), constatou elevação no pH, onde esta modificação está relacionada com o ambiente reduzido imposto pela vinhaça devido à sua elevada demanda bioquímica de oxigênio. Outros efeitos nos solos, relacionados com os complexos de troca, como o aumento da saturação por potássio, da soma de bases, da capacidade de troca de cátions e do aumento nos teores de macro e micronutrientes (Fuess et al, 2017).…”

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. Application of Waste from the Sugar Alcohol Industry in Soil as a Way to Mitigate Environmental Impacts A B S T R A C TThe adoption of practices that minimize environmental impacts and improve soil fertility for agricultural exploitation has been carried out with greater frequency. This work aimed to evaluate the soil quality in areas with different doses of vinasse and filter cake on the chemical attributes of the soil. The experiment was carried out at the IPA Experimental Station, Vitória de Santo Antão - PE, consisting of two treatments and five levels of application of vinasse doses 0; 19,42; 77.68; 155.36 and 310.72 m3 ha-1) and five doses of filter cake (0; 2.75; 11.0; 22.0 and 44.0 t ha-1), in randomized blocks with four replications. 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.
