Abstract: Results from field experiment showed that corn yield is increased from 25.0% to 26.3% and soybean yield is increased from 8.93% to 10.0% in the sandy soil and grass clay through using bacterial sludge.The structure of soil can be improved and the content of organic matter and the quantity of microorganism can be increased by using it.Therefore,bacterial sludge may be applied to agriculture as an activated organic fertilizer.
