Chemical characterization and microbiological safety of different recipes of biofertilizers Bokashi liquid

Abstract

The use of liquid biofertilizers provides several nutrients in a single application and enriches
biologically the system with benefic microorganisms. This study aimed to determine some
parameters (electrical conductivity, pH and nutritional availability) of five recipes of aerobic biofertilizers
used by rural farmers in the Distrito Federal, Brazil. The recipes were aerated using
a blender and the parameters were measured over seven days. The solutions tested reduced
pH and increased the solubility of the nutrients, indicating the necessity to test other recipes
that generate less acidic solutions.
