Abstract

The research aimed to evaluate the effect of vinasse on the chemical properties of a eutrophic Alfissol cultivated with sugarcane (S. officinarum spp.), for 10 years, in two areas of the Usina São José do Pinheiro, located in the city of Laranjeiras, Sergipe State, Brazil. The experimental design was randomized blocks, with ten replications, which consisted of two areas (Area A - cultivated with sugarcane and fertirrigated with vinasse, for over 10 years; and Area B - cultivated with sugarcane without vinasse fertigation) and three soil sampling depths (treatments): 0-15 cm, 15-30 cm, and 30-45 cm. The experimental areas dimensions were 50 m x 20 m (1,000 m2) and 30 samples were collected from each site. After the analysis of pH, soil organic matter (SOM), and levels of macro and micronutrients from soil samples, it was observed that the addition of vinasse to sugarcane crops, for ten years, has altered the soil chemical properties, with increase of soil organic matter and macronutrient content and decrease of micronutrients availability. Based on the results obtained, it was concluded that the application of vinasse increases the fertility of soil cultivated with sugarcane.
