Effect of EM Burger Dirt on the enzymatic activities of the soil planted with Bok Choy (Brassica ruba subsp. Chinensis)

Soil enzymes secure our food security; however, they are sensitive to abiotic stresses. Solving the globe issues of food waste by Bokashi may be secure for our food security. Food waste Bokashi substrate (as soil treatment) and leachate (as seed priming agent and liquid fertilizer) were used to grow bok choy 4 cycles. Soil pH, cation exchangeable capacity, moisture content, aggregate stability and enzyme activity were determined. All variables were positive corelated except catalase activity. Bokashi treatment significantly increased soil pH closed to neutral and CEC. Anaerobic Bokashi treated soil significantly reduced soil catalase activity, however it was gradually increased along the growing cycle. Bokashi treatment significantly maintains the aggregate stability along growing cycles. Hence, Bokashi substrate was recommended to improve soil quality such pH, CEC and urease activity.
