Abstract

The eco enzyme (EE) is the result of the fermentation of organic waste that reacts with acid pH < 4. The purpose of the study was to determine the dynamics of changes in the pH of the EE solution because of the application of soil containing inorganic (clay minerals) and organic (humic) colloids.  Several treatments were made by the concentration of EE solution starting from 0%, 5%, 10%, 20%, 30%, 40%, 50%, and 100%. The pH of the solution was measured at room temperature. The next treatment is to add soil (mineral and organic) as much as 0, 5, 10, and 15 g into the EE solution according to the concentration that has been made. The concentration of 5% EE solution significantly lowers the pH of the water compared to a solution without EE, and the pH continues to decrease as the EE solution becomes more concentrated (100%). The more soil colloids are added to various types of EE solutions, the soil pH tends to rise, and the pH containing organic colloids was higher than mineral colloids; this provided useful information when using EE solutions as liquid organic fertilizers in fields. The advantage of this study was that it is faster to obtain the results, but it must be tested further in the field. The application of EE solution as a liquid fertilizer is still safe against a decrease in soil pH and preferably the soil contains sufficient organic matter.


Keywords: eco enzyme solution; mineral soil; soil organic matter; pH; organic colloids; colloidal minerals
