The effect of vinasse application on the structure of bacterial communities in a Entic Dystropept and a Fluventic haplustoll Cauca Valley, Colombia was evaluated. to meet the requirements of K+ crop of sweet corn (Zea mays L.). Experimental design was completely randomized with four treatments and five replications: T1 (100% requirement of K + KCl), T2 (100% requirement of K + with vinasse ), T3 (50% requirement of K + KCl + 50% with vinasse) and T4 (25% requirement of K + KCl + 75% with vinasse). The relationship between microbial community structure and application of vinasse by PCR-DGGE method 16S rRNA gene amplicons was established. The T1 and T2. Entic dystropept showed higher number of amplicons and Euclidean distance cluster analysis, indicate that there similarity of bacterial communities in these treatments where both vinasse as KCl were applied to supply 100% of source of potassium
