Effect of bokashi compost sources on soil pH, electrical conductiv-ity and CO2 emissions

Abstract

Bokashi is an organic fertilizer that has been increasingly sought after due to its great potential for soil improvement. Therefore, this study was based on analyzing the dynamics of microorganism biodiversity as a function of the addition of bokashi to the soil. The experiment was divided into stages and conducted in a completely randomized design. In the first stage, the variation in soil pH and electrical conductivity were evaluated one and seven days after the application of four bokashi formulations (Plantae Fert®, Kefir, Microrganismos Eficientes (EM) and Sementes Brasil®). In the second stage, the pH and CO2 emissions in the soil solution were evaluated under different conditions (soil; soil + straw; soil + bokashi; soil + straw + bokashi) and application of bokashi (kefir), with four replicates per treatment. The data were evaluated through analysis of variance and compared by the Tukey test with 5% significance. Under ideal conditions, bokashi has an influence on increasing the biodiversity of microorganisms in the soil.
