“…Medina et al (2002) observed a decreased sugarcane yield when applying doses greater than 300 m 3 ha -1 vinasse. A similar finding was also observed by Zolin et al (2011), who reported an increase in sugarcane crop yields until the third year of vinasse application and a decrease in productivity from 12 to 20 years of application of 150 m 3 ha -1…”

Sugarcane harvesting is predominantly mechanical because of environmental restrictions, reduced requirements for manpower, and the quest for improved efficiency. Therefore, large amounts of straw remain available in the soil. Vinasse, a liquid waste, is a main byproduct of the sugar and alcohol industry, in addition to sugarcane straw. Both accumulate in sugarcane fields; however, the effects of their interaction are unclear. In this study, the effects of applications of sugarcane straw and vinasse on the pH and the potassium (K), calcium (Ca), and magnesium (Mg) concentrations of a dystroferric sugarcane straw and incubated for 60 days. Following the analysis, by layer, the data were subjected to analysis of variance by partitioning the degrees of freedom into orthogonal polynomials. The pH and the Ca, Mg, and K concentrations increased throughout the soil profile upon vinasse application. An acid-base imbalance was observed in the topsoil layers in association with the high K saturation. The application of sugarcane straw enhanced the effects of the vinasse across all of the depths analyzed but did not increase the pH. The best results were obtained when applying a dose of 300 m 3 ha -1 vinasse and 6 t ha -1 sugarcane straw.

Somada à palha, a vinhaça é o principal resíduo líquido da indústria sucroalcooleira. Ambos são depositados a campo; porém, o efeito da interação entre os mesmos, ainda não está esclarecido. Avaliouse a influência da aplicação de palha de cana-de-açúcar e vinhaça no pH e nos teores de potássio (K), cálcio (Ca) e magnésio (Mg) em Nitossolo Vermelho distroférrico de alta saturação por bases. Em 64 colunas de PVC de 0,036 × 0,30 m (diâmetro × altura) foram reproduzidos perfis do solo coletados nas profundidades 0-0.05, 0.05-0.10, 0.10-0.20 e 0.20-0,30 m, em área de cultivo. Os solos foram tratados com vinhaça, em doses equivalentes a 0, 125, 250 e 500 m 3 ha -1 e 0, 3, 6 e 9 t ha -1 de palha de cana-deaçúcar e submetidos à incubação por 60 dias. Após as análises por camada, os dados foram submetidos à análise de variância com desdobramento dos graus de liberdade em polinômios ortogonais. Com a

“…The environmental damage caused by discarding vinasse into the soil or running waters was an incentive to studies aiming to find alternative, economic applications for this residue. Results from such studies indicate that, properly used, vinasse contributes to improvements in soil quality [15][16][17][18][19][20][21][22][23][24][25] and agricultural productivity [19,[24][25][26][27][28][29][30].…”

Utilising organic residues in agriculture contributes to the conservation of natural resources by recycling carbon and mineral elements. Organic residues produced by the sugar and alcohol agroindustries have great potential for use in conservation agriculture. The production of sugar and alcohol generates large quantities of byproducts, such as filter cake and vinasse, which can be used as soil improvers and substitutes for inorganic phosphorus and potassium fertilizers. However, the use of these residues in agriculture requires specific recommendations for each pedoclimatic condition to prevent environmental damage.

Zolin et al (2011) found a K movement between depths of 0-20 and 20-40 cm during 20 years of vinasse application, noting that the long application time intensified the displacement of the element in the profile. Silva et al (2014) also pointed out that the vinasse provided significant increase of K to 40 cm deep, in an Ortic Quartzarenic Neosol, though, in this same situation there was a reduction of exchangeable K content, in an average of 54.5 to 50.0%, at 0-10 and 20-40 cm, respectively, from the first to the third cutting.…”

RESUMOImpacts of vinasse and methods of sugarcane harvesting on the availability of K and carbon stock of an Argisol Soils of tropical regions are more weathered and in need of conservation managements to maintain and improve the quality of its components. The objective of this study was to evaluate the availability of K, the organic matter content and the stock of total carbon of an Argisol after vinasse application and manual and mechanized harvesting of burnt and raw sugarcane, in western São Paulo. The data collection was done in the 2012/2013 harvest, in a bioenergy company in Presidente Prudente/SP. The research was arranged following a split-plot scheme in a 5x5 factorial design, characterized by four management systems: without vinasse application and harvest without burning; with vinasse application and harvest without burning; with vinasse application and harvest after burning; without vinasse application and harvest with burning; plus native forest, and five soil sampling depths (0-10 10-20, 20-30, 30-40, 40-50 cm), with four replications. In each treatment, the K content in the soil and accumulated in the remaining dry biomass in the area, the levels of organic matter, organic carbon and soil carbon stock were determined. The mean values were compared by Tukey test. The vinasse application associated with the harvest without burning increased the K content in soil layers up to 40 cm deep. The managements without vinasse application and manual harvest after burning, and without vinasse application with mechanical harvesting without burning did not increase the levels of organic matter, organic carbon and stock of total soil organic carbon, while the vinasse application and harvest after burning and without burning increased the levels of these attributes in the depth of 0-10 cm.Key words: soil fertility, organic matter, straw, leaching. Impactos da vinhaça e formas de colheita da cana-de-açúcar na disponibilidade de K e no estoque de carbono de um ArgissoloSolos de regiões tropicais são mais intemperizados e necessitam de manejos conservacionistas para manter e melhorar a qualidade dos seus componentes. O objetivo desta pesquisa foi avaliar a disponibilidade de K, o teor de matéria orgânica e o estoque de carbono total de um Argissolo, diante da aplicação de vinhaça e da colheita manual e mecanizada de cana, queimada e crua, no oeste paulista. A coleta de dados ocorreu na safra 2012/2013, em uma empresa de bioenergia de Presidente Prudente, SP. Utilizou-se o delineamento em parcelas subdivididas, em esquema fatorial 5x5, caracterizado pelos manejos (sem aplicação de vinhaça e com colheita sem queima; com aplicação de vinhaça e com colheita sem queima; com aplicação de vinhaça e colheita com queima; sem aplicação de vinhaça e colheita com queima; mata nativa), cinco profundidades de amostragem de solo (0-10, 10-20, 20-30, 30-40, 40-50 cm), em quatro repetições. Nas amostras foram determinados o teor de K do solo e o acumulado na biomassa seca remanescente na 96 Claudinei Alberto Cardin et al.
